chaincase replacement advice?

[coryf89]

Hey guys. Ive got a 2013 m8 limited here with smashed left and right side chain cases. they look like theyre a bit of a big job.

ive never wrenched on sleds before, although ive been in the dirtbike game for 10 years... so im no beginner.

just wondering what exactly is all involved in popping both chain cases off? track removal? full clutch disassembly? does the motor stay in the frame?

is there any threads here that walk you through? or a youtube video?

any tips, advice, or specialty tools required would be greatly appreciated!! thanks.

It's a pretty straight forward job. If you have to replace the case, chain and gear set, I would recommend looking at replacing with a Belt Drive vs. chain/gear set. There are a few guys making these right now. I have a MVM and have had zero problems with it. It's a sweet upgrade.

well thats good to hear its nothing insane.

this is just a sled that I bought from an auction for cheap. gonna fix it up and get it running. not gonna mod it to the nuts, so just gonna throw two oem cases on it and whatever else it needs.

Cheap 0 mile set here with all internals

Oops! minus the inner case.https://www.snowest.com/forum/showthread.php?t=430941

yeah I seen that olzy.

I need JUST the cases. no gears or anything.

I got both cases for $190. theyre gonna be showing up at my door tomorrow. just need to figure out how exactly to swap these out now!

well... super helpful forum we got here!

me and a buddy figured it out today.. pacing ourselves, having a few drinks. weve got 8-9 hours into it and had to stop because my tensioner is ruined. new one wont be here for 4 days. otherwise we woulda had it up and running in about 11 hours of wrenching. was fairly easy.. just took a long time.

skid comes off, easy.. 4 bolts.
secondary comes off, thats easy too.
few rivets on the bottom.
a few circlips are a tac tricky.

overall fairly easy, no special tools needed.


few important questions would be sweet if I could get answered.

1. chain case oil.. what kind and how much? I bought the sled with smashed cases and no oil in it.

2. chain case chain tension? how do I set it properly?

3. track tension. how is that set?

4. frogskin patches under my busted air box. new airbox didnt come with the frogskin screen. can I heat it up, and transfer it again with a sticky spray adhesive. or buy a sheet of 4x6 frogskin mesh, cut it myself, and use spray adhesive?

ok I did some reading, answered one question



for the chain tension.. Install the ratchet block; then set the tensioner in the fifth notch in the block as it is self tightening

Do yourself a favor and replace it with a manual tensioner.

Manual tensioner

Do yourself a favor and replace it with a manual tensioner.

I agree.
I'd install a manual tentioner instead of the factory one.
It'll save you some future head aches.

ah. too late now.. already ordered and pre paid for the part.

this sled isnt a keeper... just fixing whats broke, back to OEM. nothing fancy, then the next guy gets to mod it.
