Roller channel wear, what is acceptable?

I bought this primary sheave as a spare so I could experiment with machining the face and seal hump. I had it shipped to me as the guy selling it was several hours away. I cleaned all the grease out of it today and the roller channels are worn about .015" at the inside on some and about .005" on others. My original sheave has around 1000km on it and shows no wear whatsoever so I don’t really have a point of reference. It also looks like the bushing has been hot. It measures at 1.3796 (35.042mm) at the outside and 1.3791 (35.029mm) at the inside. I couldn’t find the specs in the service manual. Anyone have any input?

06 grizzly 660 axle boots

I’ve got a torn axle boot on a right rear gorilla axle on my 06 660. When I went to the gorilla axle website it asked if the axle was 19 or 21 spline. Does anyone know which an 06 grizzly would have? I don’t want to take anything apart until I get all the parts ready.

2014 700 shim and spring?

Hey guys I have an all stock ’14 700 EPS I just put 27x10x12 in front and 27x12x12 in the rear. I want some more low end right now it’ll only pull the front end in low. From everything I’m reading it looks like my best bet is 1.5mm shim and purple spring? Anything else I should do?

Shim mod

Hey guys I got a 2014 700 and got a shim to put in it just have a couple questions.

Should I order a new seal for clutch housing bike only has 500 hours on it?

And what is the torque spec for bolt on the clutch for when reinstalling clutch.

Any other advice our tricks would be helpful thanks

Tranny problems

It seems that my Grizzly has some transmission issues. Is the transmission part of the engine on these units? I just parked the thing and will look at it tomorrow. It seems to be making a clunking sound and you can feel it. I did raise the wheels and ran it. It does this in two wheel drive.

Anyone else ever have this issue. I am hoping I do not have to split the engine case. My health is not that good and no way I am able to do this, not without help.
