I know what he means[Gene Fleury and I discussed this one night].
Basically it's as simple as snugging the caps and tapping the crank end for end with a rubber mallet.This helps to seat the thrust bearing[old trick BTW].
It doesn't hurt to gently pry the rods,side to side to square the caps before the torquing procedure either.Be "nice" when you do this.
Hope that helps a little bit.

mainly just the mains...

if you put your trust bearing cap on the block without the crank in you'll notice that the cap can be forward or rearward of the block which will offset the upper and lower trust bearing surfaces..

if you basically just snug the trust bearing cap and tap the crank forward and rearward it will line the trust surfaces up between the upper and lower bearing then torque it down.

That's an old trick, but I thought everybody knew about it??
Guess it's just one of those things, that you seem to do automatically when assembling, and never give it much thought.

Thats not a trick thats a procedure that should be done on every rebuild. Reds has it right. Make sure you check for proper clearance with a dial indicator or feeler gauge if you dont have a gauge. Frank

Thanks all...I understand.

I work at a major diesel engine mfg plant and because our 14 and 15 liter main and rod caps are dowel pinned, or ring dowelled, there is no "setting" possible....thrust surface alignments are a result of tolerances...not tricks or procedures.

This is good info to know...I probably would not have thought about doing it during rebuild.

Thanks again, Bob

And Frank...I'm going to get with you again ref the heads....still working on my wife
