914World.com _ 914World Garage _ crank shaft end play

Posted by: rfinegan Apr 24 2021, 09:33 AM

Hi World,

I added the shims to my 2056 I took out of the engine to get a base line. Same crank and shims but new bearings. So cleaned the shims and installed new Flywheel WO seal and clean shims.

tight or just right? Do I hose the lube out with brake clean( dry bearing)?

Please advise

Tolerance is .003 to .006"
Lube shouldn't make a difference.

That extra .001" you see prying with a screwdriver, you're actually bending the crank /flywheel ever so slightly.
Don't do that.

Mark is the man.

I can't tell in this video if you have more than .001 end play. You should see .003 to .006 AFTER pulliing / pushing, with no further force applied. In the video it looks like you have .003 while still leveraging with the screwdriver. Or is that needle bouncing because you're pushing, resting, and pulling again? You're looking for .003-.006 at rest.

I thought I remember doing this by hand, no prying tools but it has been a while... Really feels like you are bending something more than measuring some play.

I had inconsistent results with lube on the flywheel shims, cleaned them off then got better results. then re-lubed them before torquing the flywheel

I use the feeler gauge type, I found it's just as accurate. I use two shims, measure and do the math. I then add the third shim and RMS. Don't forget the flywheel O-ring, pilot bearing, felt washer (seal) and a new large lock washer.

Once done I do one last check, so to me the lube doesn't make a difference when measuring.

Pro tip use an old lock washer when measuring your end play so the bolts don't mark the flywheel.
