Hamster,
Use Genes method. I also prefer to use dial indicator. Feeler gages are ok if you have theoil pan off anyway, and if the thrust faces of the crankshaft and the crankshaft timing gear are square and not scored. My "B" ran on the original bearings for almost fifty years. When I overhauled it the thrust faces of the front main bearing were the worst ones in the whole engine. Maybe the idea of only having thrust faces on one half of the bearing made a weak point, but fifty years service is not too bad!! Anyway, both the face of the crank gear and the thrust face of the front main journal were both scored and worn. New bearings would have helped, but not cured the problem. We ground the thrust face on the crankshaft bearing journal to square it up and remove the scoring. Then the shoulder on the crankshaft that positions the crankshaft timing gear was ground back accordingly to make the space between the gear and the face of the front main journal fit the new bearing properly. Sounds complicated, but it really isn't and it really isn't much of a job if you are set up to grind the crankshaft anyway. Worked great for me and have not had any more problems. Be sure to center the timing cove ron the crankshaft when you put the engine back together. Guys who just work on new car engines aren't used to actually adjusting things as an engine is assembled, you'll leak oil badly if this isn't right. Good Luck, Paul

Normally the end play is not adjustable but to check the end play push or pull the crankshaft as far as you can with a pinch bar or such and just apply slight pressure to the bar. Set up a dial indicator on the end of the crank. Zero the indicator with the crank at one end then move the crank all the way in the opposite direction as far as it will go. Read the indicator and that will tell you the end play. If the oil pan is off you can use a set of feeler guages and push the crank all the way to one end and stick feeler guages between the crank thrust face and the bearing face and this will give you the clearence or again use the indicator. Feeler guages are not as accurate as the dial indicator(recommended) . Most main bearing are made with the thrust made on the shell itself. Some engines the thrust is pinned or locked on the bearing cap and saddle in the block. If excessive end play is experienced you may get oversized bearings but in years of building diesel and gas I have never came across excessive end play unless the bearings spun and eat up the saddle at which time it will have to go to a machine shop and be built up and turned down.
