Listers,
 
I am attempting to measure the crankshaft end float as described in the
Workshop Manual.
According to it, you take a feeler gauge and measure the space between
the central bearing cap and the thrust washer.
 
My issue is that I cannot move the crankshaft to one extreme end in
order to create this space.
The crank rotates freely enough, but I can't get it to slide end to end.
 
Using Plastigauge I measured the clearance between each crank journal
and bearing to be:
 
Front - .002"
Center - .0015"
Rear - .002"
 
These measurements are all within range.
 
I was contemplating backing off the center cap bolts a bit to loosen the
tension, but would this create an inaccurate measuring scenario?
 
Any suggestions?
 
 
 
Peace be with you!
