  1. REV Chassis - Performance and Trail Models
    Hello, I have been looking everywhere and cannot find an answer. I have a 2003, MXZ 600 H.O. My engine is getting to a point where I think it may need to have its bearings repacked. It currently has 7500 - 8000 Miles on it. My question is if the 03 rev only has sealed bearings on the outside...
  2. REV Chassis - Performance and Trail Models
    So I've been working to transplant a 04 600ho motor to a different chassis. The sled had been sitting for about 5 years without running as it was in a pretty bad accident. I finally decided to make use of the motor as it ran good, had a pretty new topend, and I found cheap chassis to put it in...
  3. REV Chassis - Mountain Sleds
    I am ready to put my 06 Summit 800 engine together and have found I have a problem. Earlier this year I bought a MCB reman crank with right around 1000 miles on it. Everything appeared to be in order and the bearings all felt tight. Today upon inspection I found that the PTO connecting rod had a...

    My 2004 Summit 800 Shut off while I was riding. I tried to pull it over and the pull cord came out but would not retract. When i got it home i tried turning the primary clutch and it will turn by hand until a certain point then i need to use a bar but then it frees up again. When i turned the...

  9. REV Chassis - Performance and Trail Models
    Hello, I have an 2005 REV 500ss. I´m going to do an engine rebuild this summer. The motor has 12000 kilometers on it. Should I regrease the crank bearings or drill the cases for pre-mix to get to the bearings (what is the best thing to do?)? How is the reability if I should drill holes for...

    I have a project that I've started. This is the first time that I have worked on the bottom end of an engine. Just wondering how much, if any, play there should be in the crankshaft bearings. After pulling the crankcase apart the center three bearings have what I would consider a lot of play...

  14. REV Chassis - Performance and Trail Models
    looking for someone to rebuild my crank for my 03 rev 800, it spun the PTO bearing but i think it can be cleaned up. I tossed a used lower end in the sled for the season, and figured id start looking to have it rebuilt. im not sure if it would be worth it to do the center seals but for sure id...
  15. REV Chassis - Performance and Trail Models
    I just had a 05 800ho rebuilt at the ski doo shop with weiscos and a rebuilt crank with oversized bearings from JJ crankshop. New carb boots. I just dropped the sled off with all the parts paying no particular attention to bearing types figuring everything was good. About 3000 miles on the sled...

    Hi All. I am replacing the outer crank oil seals on my 77 340 olympic. i have the crank case apart and the old seals off. I have been reading about centre seals. Does this sled have a centre seal? I only see bearings in the centre of my crankshaft. Sorry if this seems very obvious but this...
  17. Mach Z / Mach 1 / Formula III Triples
    I have a 97 mach 1 700 that a o ring or headgasket went bad and poured antifreeze in the cylinder then it back fired and hydro locked and bent a rod. I found a used crankshaft for a 97 FIII 600 for $160 in good condition. I need to know if it will fit my mach 1 700 motor or not. or should i buy...
  18. Mach Z / Mach 1 / Formula III Triples
    After center oil link cracked causing havoc I tore down the entire engine to find that the crank is also bad. The PTO bearings spewed bearings onto the work bench and I found plastic shards around the mains. I know these cranks are hard to find but what are my chances and what might it cost to...

    Phasing Runout Concentricity - Part 4 of the Survivor Series After truing the clutch using a mediocre setup for the Long Range Dial Indicator, it became apparent to the experienced eye that I should take a closer look at the Runout and Concentricity of the tapered stub. I took the opportunity...
  20. Mach Z RT and MXZ 1000 SDI Models
    Tossing and Turning When I first measured the runout on the crank @ 0.0065 in (0.165 mm) the first thing I feared was the clutch being tossed around. With a little work I was able to get the fixed half of the clutch trued, well as much as I could to compensate this huge runout. At an inch from...
