    Hello,

    I just swapped engines in my ultra and now my clutch doesnt seem to be working properly. It will shift into first and hardly crawl. It doesnt move at all in any other gears. I looked at PG's site for installation of the clutch and its not very descriptive, any suggestions? Thank guys

    Z,
    Belt is the most common problem. Take the hood covers off and have someone spy on the drive pulley to determine whether or not it is turning. Centrifugal clutch should engage at a certain rpm say around 1500. Paint a white spot on it. If the belt is slipping you won't get far. Try a new belt--I think they are 43 inches. Make sure idler is working properly, (and spring has good tension). Call the factory--they are helpful and friendly. If all else fails try a smaller belt. Check the weights and springs inside clutch to make sure they move freely.

    How did you get a new motor? They stopped making that motor last year.

    yea, this isnt per say the same motor. The belt has good tension. I can see the bolt that goes into the engine shaft spinning like crazy but the clutch will spin for a couple of seconds real slow then stop and continue that cycle

    The clutch should spin all the time (at least from what you can see from the outside), even when the machine is not moving. That sounds like a belt issue.

    i took the belt off the clutch spins freely, as soon as i put the belt back on the clutch slows way down again, the actual drive shaft still spins much faster, any ideas?

    Is the engine turning 3600 RPM when in nutrel and running full throttle?

    Sounds like maybe you need what we used to do with both our Ultras. Spray some Fluid Film or WD-40 in the clutch. Run it for a couple of minutes, and that should free it up. For us, this extended the lifespan of the clutch for a few more months until we needed a new one.

    I would think spraying something in a clutch that works on friction would have the opposite effect. If I get water in mine it slows down.

    I'd be willing to bet money on the engine rpms being the issue, especially with a new motor just installed. 3400rpms is too little, and will cause the unit to barley crawl, 3700 is to much, could cause engine damage, and cause the unit to move at idle speed. It has to be at 3600 give or take 50 to work. That is in nutrel at full throttle. It will be slightly less when actually moving. I know all this because I had the same issue and talked to PG about it.

    thanks guys, im working on figuring out how to hook up the hour/tachometer to this engine. I hope this engine can turn 3600 RPM's. I never thought of that.
