Thank you, I would like to do it sooner, but in the current situation it is difficult...

I totally understand yet cannot fathom...stay safe brother.

Beautiful! All of your hard work is really coming together nicely. Getting the engine and driveline installed is a big step, you'll have it running in no-time.

Collection_153. Engine installation

So, finally everything is completely ready and this day has come! :)
Since my garage is not very suitable for installing the engine due to the lack of a normal floor and a lifting winch, I had to do it in my friend's garage. The same place where it was removed from the car earlier. But, for this, first you need to somehow get that engine out of the basement... It has quite a lot of weight, so they pulled it out in a simple and ingenious way! :)


I drew my "x" on a sheet of metal along with a wooden pallet. It turned out quite quickly and easily!


But it was more difficult to load it into the car! But the four of us did it.


Now it was necessary to get the car out. It seemed that it was even easier, but it didn't work the first time. This is all because of the "reliable" Chinese towing cables that broke three times! It was not without "victims"... my "x" suffered a little - a metal hook flew right into the bumper grill... :( But it's good that it didn't hit the headlight, or the glass, or the radiator... And it's even better that not in the "thirties"!


After all, the E30 rolled out onto the street for the first time in several years!






Of the brakes, only the handbrake works, because the calipers have not yet been installed. Therefore, we slowly and very carefully drove to our friend's garage. It's good that it's nearby, we got there without any problems.


During the work, there was no time for a photo, so the result is already ready - everything is installed from below, except for the exhaust system.


The photo on the way home was a bit unsuccessful :)


The descent into the garage was also successful.
So, the engine, gearbox with clutch and cardan shaft are installed. It remains to connect the wiring and hoses.
But even so it looks good - I like it! ;)












This is some progress! :)
Now I'm installing all the parts under the hood - next time I'll write about it.

Your build looks so beautiful! слава україні! One question, how important is this damper? I'm restoring a 1988 4 door (building into a drift car), I have been away from the car for about decade, but do have two E30's worth of parts to a certain extent so it's been a lot of digging through bins I labeled long ago. Also have ordered half an M20's worth of parts from pelican from what was available. It's a 2.7L with a 325is head and Shrick 288 on MegaSquirt 3.0 with external Bosch mosfet's driving MSD GM 44kv coil packs in a wasted spark configuration, 42lbs Mustang injectors...

Thanks!
Героям слава!!
This damper is important for comfort. It dampens vibrations from the transmission. But how noticeable this effect is, I can't say, because I haven't had it before. I think that the difference is not significant. It is definitely not needed for motorsport - it is an extra one and a half kilograms of weight that needs to be rotated.
You have a cool sports specification!

There is no photo of the cardan shaft assembly. They collected it in a friend's garage - there was no time to take pictures. But it looks somewhere the same ;)
Cardan shaft / universal joint


Part No. 1 - cardan shaft of a 5-speed manual transmission (26 11 1 225 635).

The crosses are in good shape so I left them as they were.

Briefly on the assembly of the cardan shaft.
First, we change the centering sleeve No. 1. Although it was possible to leave the old one, but I decided to replace it. It turned out not to be so simple. It was possible to pull out the old sleeve only by hollowing out its rubber part and cutting a thread on it. We press a new one.
Then we press the bearing of the intermediate support No. 10 with the shoulder close to the file No. 8. We install file no. 11, fix it with locking ring no. 12. We put the ring No. 13 (No. 15) and toothed washer No. 14 on the shaft.
We connect both parts of the cardan shaft along the slots. When I took it apart, I marked the relative position of both parts. They collected it according to these marks. Otherwise, you will have to rebalance the gimbal. We tighten the threaded ring No. 13.
We insert the elastic coupling #2 into the damper #3 and fasten it to the cardan shaft with three bolts #4.
The cardan shaft is ready for installation.

But, in fact, it was not so simple! :)
As I wrote in the previous post, the gimbal rested on the short-stroke Z3M link, so I had to replace it with a standard one. And these are not all problems.
I didn't have damper #3 before. Since, according to ETK, it should be on the 325i model, I decided to install it. But with the Z3M backstage, of course, it was completely out of place. After replacing the scenes with a standard one, I had to get up. But again, no! He resisted the pull. Since the work was being done at my friend's garage, which had to be vacated quickly, there was no time to deal with it and look for other details. Therefore, they removed that damper and installed the cardan shaft without it, as it was before.
But I was wondering what the problem was, so now, I figured it out at least a little... at least theoretically! ;)

So, as I wrote in a previous post, the pull and clamp are different before '89 and after '89. Photo from the Internet.
An early clip shifts the traction to the side, thereby moving it away from the damper.


In addition, the early thrust (25 11 1 220 838) in the area of the damper has a special stamping, and axles of different lengths.


Perhaps this is exactly what allows you to install a damper.

The late drive (25 11 1 221 657) is straight, with axles of the same length as mine.


There is also a curved thrust (25 11 1 221 250), which according to ETK is applied to engines M40, M42 in E30, and to M50, M20 in E34.


There are also two types of dampers for the E30.
Until 1988 (23 13 1 222 514).


And after 1988 (26 11 1 434 254).


So, I have a post-89 bracket, a post-89 tie rod, a post-88 damper - everything fits... Why doesn't it fit?? :)
How to make this "puzzle"? If anyone knows, I would be grateful for tips. Later, when it may become completely boring, I will still try to install it... ;)

Next time, finally, I will write about the installation of the engine, gearbox with clutch, and cardan shaft.

[The_Glory]

Collection_151. ETK_25_Gearshift mechanism

The gearbox is ready for installation, but you still need to install the gear shifting mechanism on it.
Gear shift mechanism

Manual Gear Shift Mechanism




Part No. 1 (No. 2...No. 12) - gear shift lever (25 11 1 220 326) - 1 pc. The lever is assembled, and of course I did not disassemble it completely. Second lever (25 11 7 527 254) for Z3 M3.2. This is a more "sporty" short-stroke lever. But running ahead, I will say that it was not possible to install it - it rested on the gimbal. I don't know why, but somehow they put it on the E30... Maybe for this you need a cardan with a smaller diameter from the younger models. Therefore, it was necessary to replace it with a standard lever.

Part No. 13 - gear shift lever cover (25 11 1 220 204) - 1 pc. It comes complete with a plastic frame for its fastening. I have it sewn from a leather substitute. Maybe later I will order from genuine leather.


The design of the shift mechanism is significantly different before September 1985 and after September 1985. At the same time, on early versions of the manual transmission, there is no attachment for a later mechanism, and on late manual transmissions, both types of gear shifting mechanisms can be installed. In September 1989, minor changes were made to the design and mounting of the shifter linkage. In my case, this is the latest option, after 1989 - but I realized this only when I encountered some difficulties during installation. :)
Manual Gear Shift Mechanism




Part No. 1 - gearshift lever support frame (25 11 1 221 201) - 1 pc. It can be of different lengths for different motors and manual transmissions.
Part #2 - sleeve L=26MM (25 11 7 519 669) - 1 pc. Rubber sleeve.
Part No. 3 - support frame mounting axis D=10MMX40MM (25 11 1 221 849) - 1 pc.
Item No. 4 is not used.
Part No. 5 - terminal (25 11 1 220 837) - 1 pc. Plastic clip for fixing the wiring on the frame.
Part No. 6 - gear shift lever support (25 11 1 220 600) - 1 pc. Plastic sleeve.

Part No. 7 - casing (25 11 1 220 912) - 1 pc. Rubber lever cover.
Part No. 8 - hinged bracket for fastening the gear shift lever support frame (25 11 1 220 707) - 1 pc. A metal bracket with a rubber sleeve for rear frame mounting.
Part No. 9 - M8 nut (07 12 9 906 196) - 1 pc.

Part No. 10 - straight gear shift drive rod (25 11 1 221 657) - 1 pc. After 1989. For some reason, I have it boiled in the middle, it must have been shortened. They are of several types and of different lengths. It has some nuances, but I will write about them in the section on the cardan.
Part No. 11 - plastic washer 10X16X0.9 (25 11 1 220 439) - 2 pcs.
Part No. 12 - locking clip (25 11 7 571 899) - 1 pc.
Part No. 13 - gear selection rod clip (25 11 7 503 525) - 1 pc. After 1989.
Part No. 14 - ring of round cross-section 10X2.2 (25 11 1 221 243) - 2 pcs. Only until 1989. For the version after 1989, they are not used and do not physically fit on the axle. But I didn't know about it and I still put one ring in there! The second one didn't fit :)

Part No. 15 - spacer washer 16X10.2X0.65 (25 11 1 220 199) - 1 pc. For the version after 1989, washer #11 is used.
Part No. 16 - locking washer 8.0 (07 11 9 932 863) - 1 pc.

Part No. 17 - cylindrical pin (23 41 1 466 134) - 1 pc.
Part No. 18 - elastic sleeve (25 11 1 203 682) - 1 pc.
Part No. 19 - plastic washer (25 11 1 434 194) - 1 pc. Soft plastic insert.
Part No. 20 - reverse lamp switch wiring (23 14 1 220 263) - 1 pc.
Part No. 21 - terminal (61 13 8 364 037) - 1 pc. Metal clip for fixing the wiring on the manual transmission.

The rubber sleeve is pressed into the frame using a regular bolt with a nut.


We insert the lever into the pivot support No. 6. We click the support in frame No. 1, turning it clockwise. Lubricate the hinge. We put rubber cover No. 7 on the lever and pass wiring No. 20 through it. We fix the wiring on the frame with plastic clip No. 5. We install bracket No. 8 on the frame. The upper part of the mechanism is assembled.


In clip #13, there was a large artifact in the plastic sleeve. I ordered a new bushing from the turner and pressed it into the clamp.


We insert the soft insert No. 19 into the clip. The clip is fixed on the gear selection rod with a cylindrical pin #17. The pin is fixed with an elastic sleeve No. 18.


We install the clip on the No. 10 pull. We install the thrust on the lever.
Gear shift mechanism is fully assembled.




We install the clip on the gear selector rod and fix it with a pin.


We fix the pin with an elastic sleeve.


We insert the axle of the frame #3 into the body of the manual transmission and snap it into place. We put the metal clip No. 21 on the body of the manual transmission and fix the wiring in it. We connect the wiring to the reverse lamp switch.


The gear shifting mechanism is installed on the manual transmission.


Now the gearbox is completely ready for installation on the car.


It remains only to install the handle on the lever.
Before restyling, "round" handles were available in various versions.
Gear Knob / Covers / Emblems


Maybe one day I will buy such a handle for the collection, but for now I will have the handle installed after the restyling.
Gear Knob / Covers / Emblems




After the restyling, the handles were also available in many variants. In my case, it is a wooden handle - I already wrote about it in the section on decoration from valuable wood species.
Part No. 11 - wooden lever handle (25 11 1 221 674) - 1 pc.
Item No. 3 - 5-GANG/SCHWARZ sticker (25111221611) - 1 pc.


I also already wrote about the condition of the pen - it will be restored. The emblem will also be replaced by #8 (25 11 1 221 612) M-TECHNIK.
In addition, I want to make this pen with a light. In the original for the E30, such handles were only covered with leather. But I want to keep the wooden handle. That will be later.
Retrofit kit for manual transmission leather handle with illumination




Part No. 1, No. 3 - a complete set of retrofitting, no longer available for ordering.
Part No. 2 - leather manual transmission handle with M-TECHNIK illumination (25 11 2 231 551).
Part No. 4 - leather manual transmission handle with M-SPORT/5-GANG illumination (25 11 2 231 550).
Part No. 5 - wiring of the handle with illumination (61 10 2 230 890). I don't see the point of buying it, it's easier and cheaper to make it yourself. I have already installed it, and I wrote about it in the section on wiring the interior heater. It is connected there, parallel to the ashtray backlight lamp.


The connector is original.


So, the entire gearshift mechanism is ready for installation.

Then about the gimbal.

Part No. 12 - stop (11 81 1 133 377) - 2 pcs. 1 pc is specified in ETK. But there, in the notes to detail No. 7, 2 pcs. I ordered two.
I waited almost a month for these stands under the engine pillows! Finally, they have arrived, and it is possible to complete the assembly of the motor before installing it in the car.




We screw the support brackets to the engine block.

rights


Now, finally, the engine is completely ready for installation in the car! I will install it in this form.










I like it - beautiful! ;)

However, it is necessary to install supports.
I don't really understand the function of these parts (#12), but they are called "stops". What and how they support, I do not understand - the pillow becomes free in them, and they do not support it in any way.


Maybe it's heat protection and only one is installed on the right side...? It's not clear... that's probably why almost no one has them... some kind of "extra" detail, and it's not cheap either :) But it's not for nothing that I've been waiting for them for almost a month, so I'll put them on both sides! :)

A thermal shield (No. 11) is also installed on the right side from above. I didn't have it before either.


The entire set of regular thermal protection.


I disassembled the front part again :) Thoroughly washed the entire engine compartment from dust and prepared everything for engine installation.






I will install it soon.

Collection_149. ETK_11_Engine. Cooling system water hose

For 1985 it should look like this:
Cooling system water hose


But on my car, the entire cooling system was installed with an E34 M20B25. Including a radiator with a built-in expansion tank. Its lower fastening was self-made. Now I have the stock restyling mount installed, and accordingly, the radiator will be fixed with the stock mount. The radiator will be larger, for the air conditioner. So I see no point in going back to the 1985 cooling system. Moreover, even visually, that expansion tank looks too archaic for me. And I can't install the restyling expansion tank, because another interesting tank already stands in that place, but more on that later.
Finally, all the little things have arrived, and you can continue assembling the engine.


So, the M20B25 E30 cooling system is similar to the M20B25 E34. Maybe someone will say that this is a "kolkhoz", but I will say that this is an "upgrade"! :)
Cooling system water hose




Part No. 1 - water hose (11 53 1 287 651) - 1 pc.
Part No. 2 (No. 5) - clamp L42-48 (07 12 9 952 119) - 2 pcs.
Part #3 - hose holder (11 53 1 714 433) - 1 pc.

Part No. 4 - water hose (11 53 1 722 214) - 1 pc.

Part No. 10 - bolt with washer M6X16 (07 11 9 915 123) - 1 pc.

Part No. 11 - water hose D=45MM (11 53 1 718 982) - 1 pc.
Part No. 12 - supply hose (64 24 1 374 911) - 1 pc. Supply to the interior heater. This hose is from E30.
Part No. 13 - return hose (11 53 1 720 524) - 1 pc. Return from the interior heater. This hose is from the E34.

Part No. 15 - clamp L16-30 (64 21 8 367 179) - 2 pcs.
Part No. 16 - clamp D=24.5MM (61 13 1 379 580) - 2 pcs. Plastic clamp for interior heater hoses.
Part No. 17 - bandage 120MM (61 13 1 379 580) - 2 pcs. Plastic strap for the hose (#13) of the interior heater. It is inserted into the holes on the left spar of the restyling body. My body does not have these holes, so this part is not used in my case. Instead of them, I will use a metal bracket for the restyled body.
Detail No. 5 on the first diagram for 1985 - bracket (11 53 1 279 946) - 1 pc.

Part No. 18 - water hose (13 54 1 705 568) - 1 pc. Supply for heating the throttle. This hose is from E30.
Part No. 19 - water hose (13 54 1 289 976) - 1 pc. Throttle heating return. This hose is from E30.
Part No. 20 - clamp L15-18 (11 15 1 727 509) - 4 pcs.
Part No. 21 - wire holder (61 13 1 378 529) - 2 pcs. Plastic clamp for throttle heating hoses.
Part No. 22 - hose holder (12 51 1 309 471) - 1 pc. Plastic clamp for interior heater hoses. For restyling E30.


I installed the metal tube (#8) earlier, along with the water pump pulley.


By the way, it was because of its attachment to the pump that the pump itself had to be changed. Because before the restyling, the pump did not have this attachment.


I start installing the hoses with the interior heater hoses.
By the way, in the ETK section on heating and air conditioning, there is a separate section on these hoses.
Additional water pump / water hose




Part No. 1 - return hose (11 53 1 720 524) - 1 pc. Return from the interior heater. This hose is from the E34.
Part No. 2 - supply hose (64 21 1 380 527) - 1 pc. Supply to the interior heater. This hose is from E30.
Part #3 - clamp L28-33 (07 12 9 952 113) - 3 pcs.
Part No. 3 - clamp L16-30 (64 21 8 367 179) - 2 pcs.
All other parts for M20B25 are not used.

All hoses are original and in good condition, so I don't see the point in changing them to new Chinese ones that crack after a year... All clamps are also original, some are old, some are new.
So, I start with the interior heater hoses. On the flange of the cylinder head, we install the supply hose to the interior heater radiator.


We lay the T-shaped return hose from the interior heater radiator to the main radiator and thermostat.


We install two plastic clamps (#16) on the metal bracket and fix the hose in them.




The hose will go to the radiator along the left spar.


There it will be fixed with a metal bracket to the spar.




Next, we lay the throttle heating hoses.


We screw them to the throttle flanges.


On the flange of the cylinder block, we install the supply hose for heating the throttle.




We install two plastic clamps (#21) on the metal bracket and fix the hoses in them.


We screw the return hose from the throttle heating to the lower flange of the thermostat.


We fix the hose in a plastic clamp (#21).


So far, I have installed the plastic hose holder (#22) like this - on the oil dipstick tube.


I'm not sure how it should be, but I have no other ideas :) Maybe after installing the engine, that holder can be used to fix the fuel hose... I don't know. I'll see you later.

Let's move on to the main hoses of the cooling system.
Install the hose holder (#3). It is inserted into the hole on the bracket and fixed with a pin.


I already wrote that I laid the wire from the impulse sensor of cylinder 6 together with the wire of the crankshaft position sensor. Well, that's not right! There is a special eyelet for this wire on the slag holder. I had to extract it, then translate it correctly.


Next, we fix it in a rubber shield


And we take it to the bracket.


We install the hose and fix it in the holder.


We screw the hoses to the water pump and tube.


But to the thermostat.


All hoses of the cooling system are installed.


Next, about the engine suspension.

[The_Glory]

Really fun to watch this from you!

when do you think it will drive for first time?

It's hard to plan anything during a war...
First of all, because of the damn Muscovites, I have had problems with work for the third year already, and for the last 5 months I have been completely without a job, and accordingly, without a salary. But any project needs stable financing, so everything is delayed...
Secondly, because of the damned Muscovites, now we have electricity available for only a few hours a day, and even at night. My garage is in the basement of my house, so I can't do anything in the dark. This delays even more…
Thirdly, because of the damned Muscovites, there is now an active military mobilization, and every day there is a possibility that they will be sent to the front. In this case, it is not at all known what and how it will end... it may never end at all...
That's why I haven't set any "dead lines" for a long time - it will be as it will be...
