I bolted up my flywheel with the bolts that came with it and torqued them. I noticed that the bolts protrude through the back of the crank a little, maybe 2 or 3 threads and come very close to the back of the block. The clearance is a little more than a sheet of paper. Is that normal? If not, is it safe to use grade 8 washers with the bolts to compensate?



A sheet of paper??? I wouldn't run it! Just grind a thread or two off (carefully) clean up with a die and sleep well
