An electric wheel motor cooling system includes first and second electric wheel motors (104M, 105M) and gear reducers which use hydraulic fluid for cooling and lubrication. Each of the electric wheel motor housings (104, 105) includes a sump (104S, 105S) and a scavenge pump (204, 205) for return of hydraulic fluid to the hydraulic fluid reservoir (210). A remotely located hydraulic pump (201) interconnected with the hydraulic fluid reservoir supplies and powers first and second locally located hydraulic motors (202, 203) which supply the electric motors and gears with an equal flow of lubricating and cooling oil. The first and second hydraulic motors, in turn, drive a common output shaft which, in turn, drives first and second scavenge pumps. The first and second scavenge pumps have a higher fluid flow rate than the hydraulic motors ensuring that oil is removed from the first and second electric wheel motor housings thus eliminating any churning losses of the motors or gears.
