Dryer tank/pneumatic switches/small parts


Part #1 - insulating tape (64 50 1 352 059) is no longer available, so I replaced it with ordinary thermal insulating tape from a hardware store.
Part #2 - rubber sleeve (64 53 1 372 609)
Part No. 3 - spacer nut ST 6.3 (64 12 1 379 221) - 5 pcs.
Part No. 4 - clamp D=10/6.4 (12 14 1 305 0280 - 2 pcs.
Part No. 5 - clamp D=16/6.4 (12 42 7 840 4060 - 1 pc.
Part #6, #7, #10 - self-tapping screw 4.9X19 (64 50 1 380 494) - 5 pcs.
Part No. 8 - bracket (64 50 1 372 610)
Part No. 9 - sheet nut (16 11 1 152 613) - 1 pc.
Part No. 11 - M6 nut (07 12 9 922 705) - 1 pc.
Part No. 12 - clamp (64 53 1 372 613) - 1 pc.
Part No. 13 - spacer washer 6.4 (07 11 9 931 044) - 1 pc.
Part No. 14 - spring ring B6 (07 11 9 933 082) - 1 pc.

Part No. 15 - gasket (17 11 1 150 1700
Part No. 16 - clamp D=22/6.4 (64 53 1 357 128) - 1 pc.
Part No. 17 - self-tapping screw 4.9X40 (64 50 1 380 496) - 1 pc.

Part #18 - dryer tank (64 53 8 391 025) In my case it is Knecht-Mahle (AD123000S)

I haven't quite figured out the sensors yet, so I bought a few:
Part #19 - safety pneumatic switch (64 53 1 390 070) new for E30, E32, E34 on 4 contacts
Part #20 - safety pneumatic switch (64 53 8 390 971) for E30 on 2 contacts
(64 53 8 390 536) - for E23 with 4 contacts

Part No. 21 - sealing ring. I bought a universal set of rings of different sizes - it's easier and cheaper that way.
Part No. 22...No. 25 - used to fasten early radiators for M20. In my case, they are not used.
Part No. 26, No. 27 - not used.
Part No. 28 - cap (64 53 1 363 569) - 2 pcs.
So, all the fasteners are new, small parts are ready - you can install pipelines.
Pipes

They did not look very good.

Therefore, first sandblasting.

Then electroplating.

In different years, the numbers of the hoses differ, and there is also a difference in the type of freon. I will probably deal with this directly when refueling the air conditioner. For now, just what I actually have.
Part #1, #2 - not used
Detail No. 3 - compressor-condenser pressure pipeline
Detail No. 4 - condenser-drier pressure pipeline
Detail No. 5 - pressure pipeline drier-double tubes
Detail No. 6 - pressure pipeline double tubes-evaporator
Detail #7 - evaporator-compressor suction pipeline
Detail #8 - evaporator-compressor suction pipeline
We start the installation of pipelines by installing a rubber insert in a special hole in the body. The hole was closed with a metal plug - I knocked it out while disassembling the car. So we insert a rubber insert and treat it with a wax sealant. We push tubes No. 6 and No. 7 into it.

We screw these tubes in the cabin to the evaporator valve. A rubber ring of the appropriate size is placed in each tube joint.

We install the bracket for mounting tube #8.


We screw tubes #5 and #8 to tubes #6 and #7, respectively.

We lay them along the right wing and fasten them with clamps.


Two clamps near the hood bracket.

But one collar near the hood shock absorber.

The protective corrugation on tube #8 was torn, so I replaced it. But I had to take a thermocorrugator with a larger diameter so that it would fit through the large nut. Therefore, he fixed the corrugation at the ends with metal ties. We fix the tube with a clamp to the bracket.

We install the dryer in a special hole in the body. The hole was closed with a metal plug - I knocked it out while disassembling the car. Depending on the manufacturer, the dryer can be attached with two or three self-tapping screws. In my case, two.


We install a spacer and a clamp for tube #3.

At this stage, that's all for now. Tubes #3 and #4 will be installed together with the compressor and condenser. Then the dryer and sensors will be connected. But it will be after installing the motor.
