Hey guys I have a question about the rear sprocket. On my Raptor there is some free play where the piece that holds the rear sprocket mates up to the rear axle. Is this a big deal? Is it normal? How much does this usually cost to fix?

 

Hopefully you can get by and tighten up the axle nuts but if your bearings are shot then your looking at about 100.00 or less in bearings. I wouldnt ride it that way for sure, you can cause more damage.

 

If you ride it with to much play you will eat up your carrier also.Much cheaper to replace barrings.

 

I don't think you guys understand what I am talking about. If you grab the rear sprocket and push is backwards or forwards there is some play. However this play is not due to where the sprocket connects to the piece that holds it, but instead it is where the piece that holds the sprocket is connected to the rear axle. It seems like the splines that the "sprocket holder" is seated on are worn.

 

Tighten up the 2 nuts on your axle. Every stock rapter I've seen is like this, you brake rotor will be the same too.

I agree. If you want to tighten those locknuts properly, you will need a set of Yamaha ATV axle wrenches from Motion Pro. They allow you to get the correct torque settings.

By the way, this generally starts to happen as your bearings begin to wear out which is why so many jumped into saying replace your bearings now before it is too late.

Good luck.

how hard are the bearings to replace. I will do it myself but I want to make sure that I can.

 

can someone please tell me how hard of a job it is to replace the rear bearings.

 

It is not your bearings. It is just a problem of the splines on your axle and the splines on your sprocket hub (the piece that holds the sprocket) wearing. It is normal. It happened on mine within a couple months of purchase. The bearings did not wear out for over a year. Eventually the splines will wear to the point that the axle and sprocket hub need replaced, but depending on your riding and abuse level, that may take a long time, a few years. By that time you will be ready to jump up to a new, wider axle anyway.

I figured that but while inspecting my bike this afternoon I noticed that one of the rear bearings is shot to hell. How hard is it to replace the bearings yourself?
