Damaged crankcase on '99 Mountain Max 700.
Which other model's crank cases fit my sled? I have a dilemma here as a beginner.. Two of my piston skirts broke and left a crack in my crankcase, so I need a new case # (8CH-15100-01-00) according to Partzilla cross reference..
As I'm asking on the TYclassifieds, many people are offering complete bottom ends from '01 mountain max etc. saying it will fit my sled even though the crank case has a different part # than mine..
I Checked on Partzilla an on '01 and other sleds that people said their complete bottom halves would fit my sled, and they use the same crank part # as mine (according to partzilla) but a different case (8CH-15100-03-00)..
Can I just purchase the newer (8CH-15100-03-00), put my crank in it and be good? Why doesn't partzila state this? Sorry if this question seems dumb I'm pretty new at taking apart engines and much mechanical work.. Thanks.
I need the right case that will fit my 99 mm 700. Will (8CH-15100-03-00) case fit my sled and crank. Thanks!

Partzilla isn't always right with that stuff. As far as I know....u should be able to use any redhead 600 or 700 case from 98 on up.

You can use any 600/700 red head triple that came with single headlight bulb. Different models switch to dual in different years. Dual bulb sleds have hotter ignition with different stator and flywheel. Honestly with your broken cases and at least 2 pistons broke I would be looking for as complete motor as I could find and slap the whole motor in.

I damaged my motor last year, I finally found a 2001 700 redhead motor, complete with wiring harnesses. Now I have a twin headlight! Can't ride yet, not enough snow here, but I'm psyched!
