1987-2004 warriors are the same and so is the 04-12 raptor cases will also interchange. so any warrior/raptor 350 lh crank case will fit

If you try to weld that use a tig..
But chances are your going to need to replace that side of the case..

 

[WarriorNut]

ok thanks duneracer so do they carry a differant part number and i can puchace anew one then or do i have to find a used one still and thanks again

Well I think that the reason most people don't weld them is because they crack?? Then of course leak oil all over the place..

ya thats probally what i will do had the money to buy all new ball joints and all the a-arm bearings and bushings but have to use it to fix this now but buying all my parts from the states much cheaper there alredy replaced the tierods with quad boss 12mm for 104 dollars complete vs 90 dollars apiece here plus 40 dollars for the connecting rods each and they are only stock 10mm parts

How big is the hole?
Not sure if the JB will work? Kind of thin don't want any to get in to places you don't want it to.
I have used the two part epoxy that is in a clear tube, you usually find it on the counter at a good auto parts store.
Clean the aluminum real good. I used a wire wheel on a 4" grinder. Then clean with good brake cleaner. After that dries it doesn't hurt to heat the spot up with a heat gun(not a torch). Then kneed those two epoxies together(follow the directions) and apply them to the spot. I did this on one of my other warriors it worked well.
Cheap, and very little labor.
If it doesn't work guess what its just still broke and you are going to have to change the case anyhow.
These kind of major repairs I try to save for off season.
My 0.02$

well i think my off season is here this bike is in need of some major overhauling so if iam going to do it iam going to try and do it right i have some pics now will upload them and say what my plans are and will be looking for some advise on what parts and stuff so stay tuned and thanks for all the input

dude you can Jb weld that no problem

 

[WarriorNut]

ya i know i can i actually have one that has been but i have decided to just redo the bike now 25yrs old and never been touched so figure if iam going to do it just do it right the first time my friend had the rings and that done in it just before i bought it but it needs more than that valves etc i think it needs a hole new top end jug and cylinder head talked to the shop that did it they had a hard time getting it to stop leaking with just gasgets so figure i will replace the hole thing just not sure what iam going to do with it might over size it might put new sleve in it not sure i can do the work but dont no much about the technical part matching it all up if i change the cam i know doing things to it it all has to match up plus if i keep it stock i dont know much about boring over or new sleeve and somthing about the nickel coating can do one and not the other that is why i have joined this sight iam in no hurry want to learn that stuff and do it right
