Primary drive housing broken, need some insight please.

Recommended Posts

 And the new 300FW is already wounded. Something got in a bind and blew the whole chunk of case out around the primary drive gear at the back of the motor. In the pic you can see the crack along the top...there is a big chunk missing from the bottom. And it won't roll....but the front and rear diffs both seem fine. Unfortunate. This looks to be a bit of a project. Still feels like it will shift through gears so i'm wondering if the ring and pinion just jumped a bit and blew something to pieces.  I have a parts bike.  But will this require the case to be split and transmission completely disassembled?  I assume you can't just slide the broken primary drive out and slide the replacement in?

To update this thread: Pretty sure it's going to be the one and only u-joint in this bike...the one in the axle tube.  Apparently it's not unusual to grenade the u-joint and when it does it blows the side out of the primary output shaft housing.  My oldest picked up a complete parts bike for $50 and last night i picked up the housing without the gears on feebay dirt cheap so we have some options.  The trick here is going to be getting the broken shaft out and inserting the new one without having to split the case.  I've read you can lay it on it's side and slowly slide the old one out and new one in.  Or possibly backtrace the old shaft on it's way out with thin tubing.

      It will go into neutral, 1st, 2nd, and reverse but nothing after 2nd gear. The shifter moves freely going up completely nothing but when you shift down it works. I’m not sure if it’s tranny issue worth messing with or if I should just buy a new one.  Overall besides that the thing runs like new.
