The oil pump is fully CNC machined to maintain close tolerance and strict quality control. OEM width feed and return gears. For the cleanest look possible; this pump is not equipped with a rear chain oiling provision.   Note: Drive gears; supplied in this ''Pump Kit''; will fit 84-89 pinion shafts only (models with multiple parts flywheels) and will not fit late OEM 90-91 straight pinion shafts that are one-piece with the flywheels. This kit is designed to be used with models that are fitted with earlier (pre-1990) multiple parts flywheels.  Note: There may be more differences in Harley-Davidson crankcases than you might think. Plugging or drilling a hole is sometimes necessary. S\u0026amp;S offers a drill jig as MCS 518150. This is a special tool that is mounted on the crankcase and used as a guide to help you drill holes correctly.\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 78-89 Big Twin (Fits 90-91 models with pre-90 style multiple-parts flywheels only).
