On my MSRX I went to thinner split collars to allow the primary clutch sheaves to engage the belt without having to move .080 to actually come in contact with the belt. I thought this would help while trying to engage the clutches and move at slow speeds while boondocking through the deep mountain powder. As far as I am concerned it was a great success. Now on my RX-1 I am thinking the same thing. It has to cut down on wear of the entire drive train because the jarring from a rather rapid clutch engagement is reduced down to what ever belt gap you'd like. Here's my question. I would think you'd want the gap as small as possible without belt dragging. The .010 collars appear to be the thinnest available on up to .060 through the aftermarket. I think the stock collars are .080. Is this the way to go or the .020 I used on my MSRX? Come on you racer types help me out on this one. Powder Blue
 

Split collars

PB, I know we discussed this last year. Go With the 20's or 30's and if you are not happy, you can always use a belt sander and a caliper to fix your problem. You are definitely looking where you should be. Good luck, I know you can make it work! 8)
 
Thanks Buckeye. I'm going to measure the gap I have with a new belt and buy the sheave that leaves me very little gap. I am guessing it will be much thinner than stock. Hey, at least I got one answer :lol: PB
 
Thanks Treewhacker. I'd still like to try to get over there this winter. Last winter was a non winter in our area and we are hoping for a real winter this year.
I will probably use the thinnest collars available and leave roughly .015 between the belt and the sheave.One little tidbit is I guess we COULD use the 89L or the sticky 87X belt without using the new collars. These belts I believe are a little wider than the 8DN but not nearly as durable.
I ordered a Dayco/Carlise Ultimax 3. I was a little late to pick it up today but I'll get it Monday. The cheapest place I found was an autoparts store. They retail for $69 and I am getting one for $48 (with my military discount). So, check your local autoparts store if you want to try a Dayco belt before you pay the dealers price. Sorry to drift off the topic. Powder Blue
 
Does anyone know the thickness of the stock RX01 split collars? I found the ones that were stock on my MSRX. They mic at .140
Is that thinner than the RX-1 collars? If the stock RX-1 collars are .200 then this is the thickness I would get if I purchased the collars that are .060 thinner.
Help. Powder Blue
