Main clearance is 0.001" to 0.0025". If larger than 0.003" at the center will produce a low speed thump and rear an oil leak.

Rods can be a tad tighter but no less than 0.001". Best way to check clearance is to take out shims until it just locks on the crank. Then add one shim on the camshaft side. Roll to see if there are any tight spots. If none then go to the next one.

Chipper,
Can I ignore the third party repair manuals the tell me that I must remove an equal number of shims from both sides of the connection rods?
So far on my rebuild I have adjusted almost all of the connecting rods on this '32 194 to a "snap fit" using an equal number of shims on both sides of the connecting rod. However, there is one connecting rod I can still move by hand.

I have never had a problem with using an uneven number of shims. That way you can effectively take 0.001" at a time. Elsewise you are limited to 0.002" increments. Just remember to take the extra shim from the camshaft side.
