my scramblers transmition casing has cracked 2 times since i bought it in 2000,wich is the year it was made.the first time happend with 2 hours of riding.the second time wich was august 5/02 i was on a weekend trip to the mountains outside of banff alberta.needless to say my whole trip was ruined.the first time it happend warranty covered the 900.00$ expense.this time its coming out of my pocket,and im pissed.iam now going to sell it and avoid polaris.so does anyone know what the hell is wrong with this machine or have you ever heared of such a problem?

 

If your trans case has been changed out, you may now have (not sure of the first available year)a trans case that has the provisions for the Polaris case saver. Walexa had one. A couple of things you can try:

Make sure to let off the gas before landing...when jumping.
Install an a chain tensioner. HPD and Hot Seat both sell them.
Use a good quality chain..Hot Seat sells them.
Keep the chain tensioned correctly and lubed.

MAKE SURE you have the newer style thick transmission brackets. I'm not sure what year Polaris started using them instead of the cheap thin ones, but they are a much better design.

 

Good call Kev, those came out the tail end of 99...so I'm told.

i known what you feel,i bought my 2x4 tranny last fall and it already
leak out chain case oil where the case is screwed and it is not for poor low maintenances job,didn't have a year
of running on it...that sucks!

 

Just got mine back from the shop and they said I had cracked my tranny case. How does this happen? Jumping? Rolling it?

 

polaris had some weak castings back the of the 2x4 chain drives.
cracks right around the output shaft.

I forgot what exactly they did to fix it but i think they improved the casting process and maybe added some addition webbing in that area.

(thats just what they said at the service update school)

you should be able to buy a newer style casing half, and if your mechanically inclided enough, fix it fairly cheaply.
if not i think the labor on it is 3hr 45min. plus parts.
