OIL PUMP ASSEMBLY - Part Number 98-503
This Flow Pro 1 will give an increase in oil return (scavenge) volume over stock pumps, thus increasing horsepower by decreasing drag on the flywheels and other rotating parts. Choice of end cover for custom or stock oil line connections. Cover and body are polished billet 6061-T651 aluminum CNC machined to exact tolerances for the most durable, strong and wear-resistant oil pumps. Matched feed and return gears individually matched to each body. Available for late 1973 & later single cam Big Twins; use on 74" to 140" motors. 1981 & later bolts on with no modification. NOTE: 1973 thru 1980 cases will require a simple drilling for oil drain hole. No provisions are provided for front or rear chain oiling. IMPORTANT NOTICE: Chrome plating is not recommended by Jims. The chroming process and contaminates are very sensitive to the oil pump and therefore Jims voids all warranty if the pump is plated.
