So a little progress. Rear main seal(National #5414) is in after a few questions/concerns that were answered in a separate thread here on fabo (thank you!)
Crank installed, Lord what a bear taking it in and out. I remember carrying 2 -3 cases of beer at a time as a youngster.
Mains torqued to 85 lb/ft in 3 steps.
Started at #5 then 4/2/1. Cap#3 I left finger tight so I could get #3 bearing centred.
Pried crank fwd and torqued #3 down.
Crankshaft end lay was .006" I checked it a few times.
Next is checking rod journal clearance.
Question in the last pic I have gently/loosely laid a con rod and connected to crank.
Is it ok to check rod bearing clearance with plastigauge this way? Or should rod be in the bore?
Thanks all.
