  2. Proper way to size new wear ring?

    Jet Boats
    I am rebuilding a 12jc and the impeller clearance will be a little tight with an undersized .045 wear ring. Question, Do I install the .045 wear ring and cut the impeller to .025 clearance, or can I get a wear ring to the exact clearance needed to match my impeller?
  3. Wear ring question

    Jet Boats
    Im sure this is a stupid question(s). But i wanted to run it by you guys. Currently, i have an "undersize" Ultimate wear ring in my boat. Its .010 undersize. When i measured my old impeller it came out to 7.220 and Duane recommended a .010 undersize and never run it on the trailer. Now i...

    V-Drives
    During recent teardown/inspection I noticed that the spline on the input shaft to top gear appears to be getting beat up on one side (top side in photo right were gear sits), causing slop between the gear and shaft. How bad is too bad? Time for a new shaft? Thanks Chuck

  10. Impeller Skirt Wear Ring Help

    Jet Boats
    What would cause this? I dug a few chunks of balled up bronze out of the grooves in the impeller skirt. It is obviously contacted the wear ring some how, but when installed a few years ago the clearances were good and it rotated freely. I did seize up a motor a few years back while running at...

  15. Dominator Wear ring

    Hi How tight should the blue plastic ring be on the bronze wear ring on the impeller when fitting it. It seems to me to be too tight / I can get it on ok but is a slight tap fit to get it in position. Then the OD of the blue ring into the housing / what should the fit be like there. Stainless...
  16. Wear Ring Removal and Installation

    Jet Boats
    Ok guys I am questioning myself. I heated up the insulator ring and as it was melting i removed the brass wear ring. The insulator looks ok I think. My new wear ring will not go in. Do I need to heat it up again and slide it in? I have a pic I will post in just a few

  20. Ultimate Wear Ring Thread (Question For DuaneHTP)

    Jet Boats
    The Ultimate Wear Ring has a much lower coefficient of friction to water as compared to that of a metal wear ring. This reduces frictional horsepower loss within the pump's mechanical assembly (between the impeller and wear ring), which slightly reduces the load on the engine, allowing the...
