914World.com _ 914World Garage _ Swapping flywheels and end play

Posted by: yeahmag Dec 4 2018, 12:23 AM

I’m getting ready to swap flywheels and was pondering end play. Assuming the new flywheel has the same measurement from the thrust surface to the crank mating surface the end play should be the same. Right?

Not, everyone is different. Got to set the end play. I set it every time I have the case's apart.

When I built my engine the end play was on the loose side of the range but with the available shims it was either that or too tight at something like .0025.

then when having the engine out again for a suspected RMS leak at 2K miles I discovered the end play had opened up some, and by switching shims got it too a much more respectable .0032

I would check it anytime the trans is off the cases.
