    So belt anignment is wrong and the adjust thing is doing nothing, the "big nut" on the end of second clutch what pushes the helix. What is wrong with it?! :D

    This weekend my local dealer sold me a 417300551 belt, I cannot find any information that says this is the correct belt for me. Partzilla and skidoo parts nation says I should have a 417300531. Anyone have any information or first-hand experience running a 551 on this sled? It seems to be for...

    I want to start a discussion on pulley distance and alignment on the Gen5 deep snow series. I have information to share and I'm sure others have too. The only one I saw was on Big John's facebook (Sled Head Racing). I have access to a Gen 5 D.S. and take both measurements, static XYZ and loaded...

    From the Factory my 900R belt was even with the secondary. (top of the ribs) In the owners manual it shows that the bottom of the ribs to be even with the secondary. This adjustment seems to be in line with all 850's. Before the first ride I adjusted it to where the owners manual and all other...

    So I blew a belt the other day on the trail, went to go swap it out and when I took the belt tool out it somehow pulled the grooves it goes into with it now they’re stuck to the belt tool. I tried adjusting the deflection since it wasn’t sitting right on the secondary but not sure what I’m...

    My clutch will not tighten down on the belt creating almost zero power. Any suggestions? Out of the blue this happened

    Working on a 2017 850 summit, trying to adjust the belt as it is way too high in sheaves. The adjuster nut is against shaft and shim is loose but belt is still to high. Any help much appreciated
  8. REV-GEN 4 & 5- Summit/Freeride/ 850 Turbo
    So, I bought new-to-me 850 Summit SP 146. I've only put something like 100 miles on it. Lots of power. It's an awesome sled so far. However I am a bit concerned with the reputation this sled has for blowing belts. Out for a ride today and I decided to wind it out and see what she'll do. I...

    Alright guys, just got back from a ride today that included a lot of lake running and I officially have the slowest 850 in the group, by A LOT <_< at the start of the season I installed a Laflamme clutch kit and at the same time switched to an ultimax 821. RPM today was right around 8000 but...

    2009 800 ptek renegade. So earlier last week I was riding along and all of a sudden I lost drive and could hear the belt aggressively slipping. I stopped immediately and saw that the clutch sheaves were pretty much all the way open. I took off the belt, inspected it, and put it back on and then...
  12. REV-XP / XM Chassis - Mountain Sleds
    Hello everyone just curious if anyone has any solutions for lowering temperature near the clutching? My sled tends to eat some belts due to high high temps. Don’t get me wrong I ride it hard and things get clogged so I know the temps get hot but I take breaks during hard riding but it’s...

    I have about 1500 miles on the first belt on a 2018 G4 850 Backcountry and am wondering about when to replace the belt. I have adjusted the driven pulley several times and it needs an other adjustment but the top of the belt still measures 1.47 inches which is the same as a new 531 belt that I...

    Just picked up a left over 600r for my wife. I was checking over the sled this morning and noticed the sled had a 417300383 drive belt installed on it. When I look at the accessories catalog the PN for the machine calls for 417300551 belt. Does the dealer install the belt or the factory? Zero...

    2008 Expedition TUV 600 HO SDI Stumped as to how to access the belt height adjustment screws and nuts on the secondary clutch. Myself and a mechanic friend can't figure out how to get a tool in there since it is so close to the gearbox. The service manual makes brief mention of a belt height...

    Hey all. As my name suggests Im new to sledding. Bought an '06 500ss with 4500 miles. Runs great but I get a "clunck" when the clutch engages the belt. Normal? Or is this something I should get out ahead of? Thanks
