[QUOTE="greg brillus, post: 148391, member: 597"] The punch locking was only done in a light fashion to simply stop each bearing from falling out of the hot case when the case is flipped over to carry out work on the other side of the case........Not to hold the bearing firmly into the bore for each bearing. If the punch marks are done too heavily, you will deform the bearing directly where the punch marks are, and the inner will spin with a ratchet like action. The use of screws to secure the bearing is probably ok on a stock road engine, though it is something I don't do myself.......I've seen it done on a chopped race engine with absolute disastrous results, the drive side case split right through were these screws were used to anchor the bearing.......There were other reasons why this happened, but it still did it. I've only seen lipped bearings used on one engine i had here, and their use needs to be done very carefully.......as the width of the lip needs to be set up wide enough for the total width of the crank set up.......On this one, when the case halves were bolted up together, the crank would lock up.......So I heated the cases and replaced the bearings with normal rollers. The cases should be heated to around 170 to 180 degrees Celsius max......200 is too hot, this will anneal the alloy........Measure the housings accurately races should have 0.001" minimum interference........Most bearings measure 2.499" so housing should be 2.498" or slightly less........Good luck.
