Hi guys,
Just put new rings on my pistons, honed the cylinders to remove the glaze and had the crank polished and all new bearings. Now that I have the crank in, and the rods and pistons I'm wondering how much effort it should take to turn the crank. Seems the oil rings are fairly tight. All end gaps are within spec. The rings I pulled off of the tractor had huge gaps, some as much as close to 1/8" .
It has been about 25 years since I rebuilt a motor of any kind and would appreciate some feedback here.
There seems to be one spot in the rotation that is causing a bit of resistance more than in other areas.
This is a 1949 8N, with the thicker cylinders.
