MadMike 11 Posted May 4, 2012 Time to do a full fluid change. Manuals list alternates for the Hydro unit. Multi purpose simplicity fluid or Trans A, F, or Dextron. What about the Bevel Gear Box, manual doesn't list alternates for it? I would assume the same alternates would work, but thought I would check. Thanks in advance.

BLT 725 Posted May 4, 2012 The bevel gear needs a lubricant that has EP(Extreme Pressure)qualites because of its hypoid gear design similar to automotive rear drive differentils. I don't think there are many choices there. Share this post Link to post Share on other sites
