slag_350300 Posted April 22, 2011 Report Share Posted April 22, 2011 I split the cases on my engine a minute ago and found one of the pins on the clutch side outer crank bearing wasnt in the hole on the bottom of the bearing seat on the case and made a indentation on the corner of the case where my finger is pointing. on the other side there is a factory machined slot for that pin to lay in and not on the other side. also the piston blew apart in a million peices and scraped and dented the case where the crank rotates. Do I need another set of cases? Quote Link to comment Share on other sites More sharing options...

dirtydownunder Posted April 22, 2011 Report Share Posted April 22, 2011 they look ok, the main area for the bearings is still pretty good. just clean up the edges of the damage. are you going to run a crank that has the orings on the bearings instead of the pins ?

okbeast Posted April 22, 2011 Report Share Posted April 22, 2011 You should be fine. If the next crank you get has the pin on teh bearing just make sure it lays good in the groove. And on the bottom case, just make sure the crank rotates fine without hitting anywhere. Quote Link to comment Share on other sites More sharing options...
slag_350300 Posted April 22, 2011 Author Report Share Posted April 22, 2011 The next crank I will be putting in is a hot rods +4 stroker crank with the max load bearings. I wasnt aware they made ones for o ring instead of clips. Good to know I was worried Id have to find some cases. Im starting my 421 serval build. Pics will be posted in the process.
