I have a late model 2004 Sportsman 500 HO.
The service manual calls for the front gearcase to have 150 ml of "Premium Demand Drive Fluid for the Centralized Hilliard gearcase". There is no mention of a rear gearcase, and if not mistaken it shares with the transmission.
I went to my Polaris dealer and they sold me two bottles.
They said the front should be 120 ml of "Angle Drive Fluid" and the rear has 150 ml of "Demand Drive Fluid for hub and centralized hilliard clutches".
I am confused as to what I should replace the gearcase with. Neither my owners manual nor the service manual mentions anything about a rear gearcase, and the service manual says to put nothing but the Demand drive for Hilliard GEARCASE.
Does anyone know what gives? I am tending to trust the service manual over the counter clerk at the dealership at this point. Last thing I want to do is mess things up right before my big trip.
