crankcase shims

[1951 adam]

I was bolting my crankcase in the frame, and I found .010 gap between the right front ear and the frame boss....should I shim in between the case and the engine , There were no shims when I removed the engine...but .010 seems a bit much for me...I was looking for a shim washer in my stash...nothing that thin, any suggestions?

.010 isn't that much of a gap and yes you should shim it. The colony kits has different thickness shims and there are some thinner ones in there. Or you could use shim stock, etc.

cut the .010 piece off your old extra feeler gauge if you have one.

Funny I was thinking of that....but its not wide enough across to fit through the bolt, I think I need more surface for the case to sit on. Thank you for that

Adam, do not do this! The front feet have to be totaly supported. Do not use alumimum by no means! Bolt your rear down tight and use a feeler gauge. Go to McMasters and just get some stainless steel shim stock and do the job the right way. Bob L

ps: I run an 1/16" shims on my 48.

[1951 adam]

Bob, I will look for some stainless stock, I also think that aluminum will crush too much, I'll see what I come up with at my shop, Thanks for the imput, Adam

Thank you George

Your welcome...

If you were here where I live, I would bring you home a 1" x 6" piece of .010 titanium stock that we have at work, for engine cowlings and heat shields........cut on a big shear we have in the Airframe shop.

Come to think of it, I may just make myself a couple to pack away for when time comes to put my project together.

Enough pressure to crush an aluminum shim will snap that crankcase in half first.
