I have a 2000 trailblazer and need to change the front sprocket. I believe all i have to do is remove the c-clip. Is this correct ???? I also heard they make a tool for this application... i'm sure its worth it but can I do this without the tool somewhat easily (getting off and putting back on - greased). I'm sure I could pop it off but is it easy to get back on without the tool.....

also I see there's a yellow "dip stick" plug w/two o-rings and a "safe" zone area for the drive fluid ??(sprocket side). well mine doesn't even read anything. possibly dry. what type lube is required and where do I fill it at (same plug hole?)

thank Scott

 

Having a quality C-clip tool is a must for anyone who does there own repairs/maintenence. They are cheap and just about any hardware store should have them. I wouldn't chance bending the c-clip and having it (and the sprocket) come flying off while riding by not using a <$10 tool.

 

THANKS !!! I'm buying one today !!!!!!! will need it for front wheel bearing change on my sons kx80 also, new to the repair world !!!!

You can change the front sprocket without snap ring pliers but you almost need 3 hands. It's a real pain if you don't have them. If you can, buy a pair with interchangeable tips. The tip with a 90 degree bend at the ends seems to work best.
I did buy the pliers before I changed the front sprocket the last time and it was so much easier.
As for the trans fluid, the only fluid you can use is Polaris's transmission fluid. You might want to top it of before you do anymore riding. We're talking big bucks if anything were to break.
I just replaced both sprockets (Sunstar) and the chain (Renthal Gold "O"Ring R-3). Should I expect these to last longer than those sold by Polaris?

Snap ring pliers are a must if you do your own maintenance. Like he said, make sure you buy the pair with movable ends. I just changed two front sprockets, and found the 45 degree angle setting to be perfect for getting to the snap ring. Even a newbie should be able to change a front sprocket in about fifteen minutes, if that.

 

Thank stickinmud, but can I use a 5-30 or even a 10-40 weight oil like I do in my sons kx80 dirt bike.....(like yamalube made for gearbox/transmission, that polaris stuff cost $10 a quart for synthetic and yam's is semi-sinthetic) .

anyone, thanks Scott

 

For something you only have to change annually, use the designed fluid. Polaris synthetic gearbox for the trans, and I would recommend Mobil 1 10W30 for the counter balancer. I think the trans only takes around 12-13 ounces. You can buy the jumbo jug, save money, and cover yourself for many years. The money you save cutting a corner, could cost you a trans.
