gomerkfx700 Posted June 24, 2013 Report Share Posted June 24, 2013 I'm putting a engine together for a friend who bought a rebuilt crank from a member the crank came strate from hjr. When I went to put the crank in the bearing keeper groves on the bearing and in the case doesn't line up. Its off by about half the thickness of the keeper has anyone had this problem before. Its a 4mm hot rods crank that Kevin replaced I think a rod on and trued and welded. It was shipped strate from Kevin to my buddy no middle man Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted June 24, 2013 Report Share Posted June 24, 2013 Move the bearing. Press or pull it. I believe that's what your talking about. The drive side? Quote Link to comment Share on other sites More sharing options...

gomerkfx700 Posted June 24, 2013 Author Report Share Posted June 24, 2013 Well I have tried moving the bearing they both are pressed as far as they can go. I'm afraid to put any more pressure on the crank its like the webs were welded without being to specs Quote Link to comment Share on other sites More sharing options...

camatv Posted June 25, 2013 Report Share Posted June 25, 2013 is the other side of the crank rubbing the case? if its too wide it will rub OR there is a wacko chance you have a screwed up bearing. or a screwed up machined side webb on the crankshaft..?

gomerkfx700 Posted June 26, 2013 Author Report Share Posted June 26, 2013 Bearing will not press any farther. But the rod tolerances from side to side inside the webs are sub pose yo be between .25-.75mm one side us just a little more then 1 mm. I believe there us were the problem is when the crank was rebuilt and welded it wasn't pressed together fully. Quote Link to comment Share on other sites More sharing options...
Wildcardracing Posted June 27, 2013 Report Share Posted June 27, 2013 Rod clearance should be around .020 Quote Link to comment Share on other sites More sharing options...
gomerkfx700 Posted June 27, 2013 Author Report Share Posted June 27, 2013 The stator side is 1.295mm and clutch side is .711mm I'm no professional but im pretty sure if those was in specs I wouldn't have this problem Quote Link to comment Share on other sites More sharing options...
