Pro Engines CNC Machined Nissan RB20/25/26/30 Oil Pump Drive Collar

Our Nissan RB Oil Pump Drive Collars (also known as Crank Collars) are precision CNC machined from Chrome Moly barstock. Our collar replaces the narrow oil pump drive originally machined on earlier Nissan R32 RB26DETT crankshafts, as well as all RB20DET, RB25DET, RB30E and RB30ET crankshafts. It can also be used to replace a worn oil pump drive on R32, R33 and R34 RB26DETT crankshafts. Our collar provides full engagement on the inner oil pump gear which greatly reduces the likelihood of oil pump gear breakage in these engines.

Each collar is supplied with detailed instructions and fasteners. Machining is required to fit this collar and therefore it can not be fitted to a crankshaft while still fitted to an engine. We can supply and fit the collar to your crankshaft for AU$350, or AU$550 to chemically clean your crankshaft, supply and fit the collar, check journal sizes, micropolish the crankshaft journals and fit screw in oil gallery plugs.

We have collars in stock ready to ship.
AU$150 each or AU$125 in multiples of 5 or more

Customer Testimonials:

"I have purchased 4 or 5 (collars) so far from Pro Engines. Very good service and they get it to you very quick as well "

"We have used the Pro Engines crank collars on 10 or so RB30's and not had a single problem. They are a good sweat fit on the crank and run tight tolerances (clearance) for the N1 oil pump drive flange. Excessive clearance/crank flange wear is one of the causes of oil pump rotor failure.
