I need some advise on what may be an abnormal problem. I had my crank turned at the machine shop and my block fully dipped cleaned and tested. They turned the crank for .010" over and I installed appropriate brgs. Issue is that the crank is difficult to turn when in the block without any caps installed. I can get it to turn but not easily. When I install any cap the crank is very difficult to turn.
- I verified the clearances with plastigage and right on at approx. .00175".
- I am thinking the bearings themselves may be too large in diameter because there is wear on the bearings at the gap. See pics.
- the wear in the pics if from only several hand turns of the crank. The small one in JPG 336 had not been rotated with a cap installed, only cap installed for plastigage.
I have not assembled an 1800 before but other cranks turn very easily. this cannot be normal??? Crank bent?
