[QUOTE="whenfoxforks-ruled, post: 1415003, member: 73147"] Drive the crank ends as straight on as possible. Only kawasaki main bearings stick to the crank, and move around in the bore, imo. That crank should move back and forth relatively easy, and the main bearings should stay put. A loose case bore to bearing is bad, red loctite, and keep it out of the oil passage. Both your main bearings installed from the inside, or the right one is held in from the right? The drive gear and collar is not pushing the bearing into the bottom end I hope? Next idea is if the crank got pressed all the way together? Generally the big end pin is flush on the outside of both crank halves? The left main bearing is flush with the inside case? The right should appear the same. You are sure you have the correct collar, and the drive gear is not backwards? Lastly, you do have the correct main bearings? The size is usually printed on the bearing, except real hardcore Chinese junk. Not recommended! [/QUOTE]
