i got my block back from the machine shop and started putting the parts back together. i put the crankshaft bearings all in place and used some bearing grease to spin the crank. without the lower crank case the crank was spinging. so i put the case over it and tryed to spin it again and no luck....... i printed the torque specs of mitchel and it says 15ftpounds and the a degree turn (dont remember what degree this moment) so i pulled the lower case off and every thing looked alright..... tryed it again and it did the same thing. i got really frustrated and quit for the night



any ideas?

15lb/ft + 70* SI says to use clean engine oil to lube the bearings. Thats what I use when doing them under warrenty and have never had a problem. Maybe the grease is too thick. Did they have to redo the bearing surfaces? Make sure you have the right size bearings. Just throwing out some ideas.

never trust new bearings are perfectly right.

that crank should spin easily.
