Crankshaft spin effort during build

1slowfiveoh · Sep 18, 2006

Just curious, how easy should the crank spin by hand when the maincaps are torqued down snug? Mine spins pretty easily without a bolt in the crank and the plastigage was within spec. when I checked all the bearings for clearance. I just am just being cautious because I don't want bad stuff to happen. Thanks!

what were the clearances on the mains

it should spin without much effort.

SBF, They were all within .025mm if I remember correctly.

Brand spankin' new block
Brand new crank
standard size bearings

I am just really nervous about assembling this engine because it is my first time doing so. I have 2 books and 1 DVD but I still can't help but be a bit aprehensive.

you mean .0025-.0030?

1slowfiveoh · Sep 19, 2006

oops.....I guess I forgot a zero.

R2D2 · Sep 19, 2006

your fine, what was the thrust? How many thou?

1slowfiveoh · Sep 19, 2006

The thrust I measured with a feeler gauge because I do not have a dial gauge. If I remember correct it was between .006 and .007 both forward thrust and back.

I looked at the Chilton manual and they say .004 Through .008 is acceptable. Please, correct me if I am wrong.

Thanks for your help!!! I am sure I will have more questions as my assembly goes on.
