Lower case

[Michael<NOOB>]

Hey guys noob here and don`t know a whole lot about 4 wheelers but I borrowed my friends 2002 banshee. We went riding and i attempted a hill climb and failed. After the fall to the bottom the right crank case had busted, after removal of that lower crank case broke.

 

Question is do you have to remove the engine to replace the lower case?

 

We kicked it over after it busted and it fired right up, we shut it off. Just a noob that now has a new addiction.

Yes you do. You will need to replace the top and bottom case as a pair.

You can't just replace the lower half. You're talking about complete engine disassembly and case replacement.

Is there a place other than ebay that you can buy the complete case together?

I bought the lower case off a guy on here. Good seller shipped quick and amazing packaging along with it. Now to rebuild ended up needing a piston to. So now we are waiting on that to get here. Im going to search torque specs next. Thank you guys for your help.

Pick up a manual and get some yamabond or decent gasket sealer.

put the case halves together empty and check the alignment of the holes for the bearings, to make sure they all line up, case halves are machined in pairs, but sometimes you get lucky. you may be ok if your lucky.

They MAY line up, BUT are they machined correctly to the right diameter? Yamaha line bores the case set when they are bolted together and when you start mixing and matching case halves it throws off the diameter of the holes for the crank and tranny shafts/bearings, due to the parting line being slightly different in EVERY set of cases. If I was your buddy, I would demand that you use a MATCHING SET of cases. Some guys have got away with mixing them, but other people have had ALL KINDS of wierd problems after doing it. Be a REAL FRIEND and fix your buddy's bike correctly instead of turning his pride and joy into a POS.
