If the RGM drive is the same as Hayward then the belt is ok to run in oil or ATF. This gets rid of the need to ventilate the case to cool the alternator & would keep various bearings/sprag clutches lubricated. ~I must have thi only clutch that has worked great from day one with original bronze plates. It did need the plates cleaning every 3000 miles or so as it would slip under power, until I cut radial grooves in all the bronze plates about 1/2 inch apart, to disperse the oil off the surfaces quicker. I have not needed to touch the clutch since.
