Grumpy:
I got involved in a discussion about friction reduction during assembly of an engine. The other person was saying that the crankshaft can be easily spun after torquing the main caps prior to assembling of piston/rod combination. Just wondering what your experience is in checking the alignment of main caps, with and without bearing inserts, crankshaft main journal alignment or concentricity to make certain both the block and crankshaft are as near perfect in alignment.
It would seem that if the alignment and clearances were where they should be and applying oil pressure to the mains ALONE, the crankshaft SHOULD spin freely. As in spin it by hand easily.
Looking forward to your comments on this situation. Thanks.
