END PLAY
Setting crankshaft end play on engines that you do frequently can be made easy and save time. If you do enough engines, you will always find yourself lapping thrust bearings to get desired end play. Start recording the width of thrust bearings after you have lapped them and achieved the end play you like. Keep these measurements in your notes. If you prep the bearings before final assembly, you won’t have to play the “Crank thrust games” when everything is lubed up and ready to assemble.
