I picked up my case and crank from the machine shop and am trying to determine which bearings to purchase. Starting with the case and crank:

Measurements from the machine shop are:
crankshaft housing bore sizes:
#1 2.757"
#2 2.757"
#3 2.757"
#4 1.970"

according to the workshop manual section 0.2-2.2 tolerances and wear limits:
bore for crankshaft bearings
#1-3 2.7559-2.7567"
#4 1.9685-1.9701"

Measurements from the machine shop are:
crankshaft main journal sizes:
#1 2.3612"
#2 2.3613"
#3 2.3614"
#4 1.5740"

according to the workshop manual section 0.2-2.2 tolerances and wear limits:
#1-3 2.3610-2.3618"
#4 1.5740-1.5748"

All this looks to me to be standard size bearings but I am asking for comments and observations etc, TIA.
