How do I get this off??

[MIKe30]

Am trying to take the lower timing chain cover off but i need to get the crank pulley/nut off first. Dont see it in the bentley how it's done and it's not coming off with a wrench and a screw driver wedged between two bolts i put back in.

tried sending a picture to my email twice but its not working. I'll look on real oem to help you all get a better understanding of what exactly i mean...

thanks

+1 I think the big bolt and a lot of force is your solution. I'm sure w/ being stuck on there tight since it rolled off the assembly line its gonna take a bit of force to work it loose.

gotta remove the bolt. its speced at 600 ft lbs if i recall correctly, and a real bitch to get off. i use a 3/4" impact gun for mine.

[golde30]

have to take off the big bolt for sure. get a 1/2 socket wrench on there with a 5ft pipe, will come off that way.

Like Cary said, long pipe and a buddy to hold the engine. You may also need a spanner tool to hold the crankshaft from spinning. The big bolt takes 300 ft-lbs to remove. For the hub (circled in red in you pic), you'll need a hub puller, check sears for that.

Puller in use:

yes, it's the big bolt i can't get off. Looks like i need to get the crank lock tool... old man's air gun didnt work either.


thanks

only m5x nut i ever removed took my ingersol 1/2" impact, 150psi and like a minute of solid hammering then it spun free.

Is the motor in the car or on a stand? On a stand easiest way to lock crank is probably pull oil pan and wedge a block of hard wood between a crank counterweight and the block.

In the car put the rear wheels on the ground, ebrake on, tranny in 5th

If you use the impact gun do it for 1min+ continuously. I know it took at least that long to remove mine.

thanks guys. I started doing it for a little bit but i need to find the 6pt socket that's around somewhere... the 12 pt is doing a number on the nut

Dude-make or buy the hub-holding tool. It's totally worth it. Take a 1/2" 3-foot breaker bar, stick the end into a pipe, put it on the bolt so that the pipe is up at an angle, and pull down slowly. I installed the holding tool and rotated it up so that it became wedged on the water pump. I then held the engine with my left hand, reached up with my right to grab the pipe, and then pulled down slowly.

If your air tool is not working, you may need a compressor that puts out more cfm's. My air gun only goes to 220 ft-lbs or so, so that may also be your problem. Good luck!

How do I get this off?

Use lubricant, rub gently, repeat.

One other handy thing that Funkmasta taught me was to take a 2x4 and stick it inbetween the crank to get it so it won't turn. It'll bite into the wood a bit when you try and turn, but won't score anything since its wood.

That won't help if you're trying to do a front crank seal in the car.

I would take an old crank damper and weld a pipe to it. Oh wait, I already did... :p

[Dissembler]

holy crap, it took you guys ONE MINUTE of solid hammering with an impact gun to get that big retaining bolt out!?!?! I also have a 1/2" ingersoll and my shop only runs about 110 psi, mine came off in all of 5 seconds on my M52

MIKe30, make sure you remember how the vibration dampener, pulley and hub all line up-they've been spinning together in one orientation for a long time, and vibrations can develop when that marriage is changed.

you should not need to use a puller to get those off. If you get that big main bolt out, everything you want will wiggle/GENTLY pry off as an assembly. I've pulled vibration dampeners off a lot of cars, and the only ones that need a puller tool are some GM vehicles because they are designed to be pressed on and off. Mossman is right about how to prevent the crank from moving. Also, whatever you do- NO HEAT. And the dowel pins on those lower covers can be a pain as well as the little torx bolts that go through the head into the top of the cover (all 4 of em)
