Do you have the original engine and trans combo? Or has your been replaced with say an automatic? If so you have a flex plate inplace of the flywheel, inwhich case the ring gear is welded to the plate. If in fact you do have the original flywheel you simply cut the old gear off . Heat up the new gea...

Mine served with the USFS than was sent to South Saulty volunteer FD in Alabama. I called and spoke with the Chief had a long conversation about the truck. It too had the bed removed, a ton of switches added to the dash, partial 12volt conversion. Which made the truck hard to start. It served as a b...

pulley
Front crankshaft pulleys are secured in two manners that I know of. 1) Woodruff key. 2) Blind spline. These engines use the woodruff key.

one other thing that I have seen before is a broke crankshaft usually ringht at the end of a main jurnel.

This will remove any small high spots or grinding grooves left over from the stones. Also the lapping compond must be cleaned from both valve and se...
