Well my season has been done for a bit now but, before putting the sled to bed I figured some clutch maintenance was in order. My first debockle occurred trying to get the primary off with my removal tool from my Rev . That's right, the Rev tool fits the newer XM's, or at least it did for 3 prior clutch removals on the XM but on the 4th it failed miserably, tearing the threads on the primary! Needless to say that was a pricey mistake. As you can see from the pic the newer XM tool on the right is a bit different, most importantly the threads engage more of the clutch than the older Rev bolt, who knew!!
The primary was still in pretty good shape after 4700km and no repairs! However, as you can see from the wear pattern on the ramp, there was the start of roller wear and/or pin wear so, the cheapest route to do the primary is just to buy the clutch kit and get the new bushing/clip for the outer sheave. I included a pic of the belt wear on the outer sheave simply to show that it is time for a new belt, still have the original on, only adjusted the secondary twice over 4700km! The belt actually looks in primo shape but, I'm guessing that heat has taken its toll on it and its starting to break down so new one for next season.
The secondary turned into a bit of a gong show. I made a puller for taking the fixed secondary off, still like the old secondary design better. It was all pretty much pristine but there was wear showing on the helix bushing as seen in the pic, so figured I should swap that out. Here's the weird part, you can order a new bushing and clip, but the shop won't put it in for you, because the BRP manual says to replace the entire helix. Bushing, $28, new helix, $145 ?????????????? Well, being the cheaptard that I am I of course went for the bushing. The shop "tried" to get the old bushing out, to no avail. There is no "lip" on the inside of the helix to be able to pound or push the old bushing out. So, I cut the bushing in several spots in an attempt to merely pop out the pieces of cut bushing and then press the new one in. No go, would appear the bushing was also glued in at the factory, because it would not budge. Well, at least until the point a chunk of aluminum broke off with the bushing attached, ya, need a new helix!! Also put a pic in of the secondary spring, the new one is nearly a 1/4" longer, definitely time to replace that.
All in all I am very impressed with the clutch and the performance of it over 3 seasons, so I guess a couple bucks into it at this stage is warranted. Clutch parts and a new set of plugs (originals again, was hard starting near the end of this season but the new plugs fixed that!). Still cheaper than a new 2018 !
