cracked case

[fesse]

Hi guys. New here. I' ve been out of the fourwheeler thing for a couple years and decided that a little blaster would be a cheap way to get back into it. After some searching I picked one up with a broken case. The trans oil leaks into the engine. I did a search but had trouble finding any good information on rebuilding the bottom end on a new case. My question is how hard is the rebuild and am I better off just trying to buy a new engine/rotating assembly

A great thing about owning a Blaster is how easy they are too work on Get yourself a manual and give it a good once over and you shouldnt have any problems rebuilding your bottom end.

Oh by the way welcome to BF. Your all you need to know about your Blaster one stop shop.

Oh and here is a link to a downloadable Blaster manual.

it's very aparent. and it's welded back together. i have a lead on a good case from a blaster that locked up. i'm only woried about trying to seperate the case without any recomended tools.

I bought a bearing seperator kit at harbor frieght for my kdx and it worked great on the blaster I only needed a couple of long m8 bolts

it was like this one but only $29 - Harbor Freight Tools - Quality Tools at the Lowest Prices

and I used that black double fork thingy in the middle with the m8 bolts on the flywheel side.
