Oil Pumps are the most overlooked part of an engine. It doesn't make sense to put big bucks and time into an engine and then tack on just any old off brand oil pump.

CB's Maxi Pumps are the only VW oil pumps that have the main drive shaft locked to the pump gear with a wedge key. They can't slip or lose oil pressure. The driven gear runs on a shouldered shaft that locks it firmly in place. It can't be forced through the pump body and jam against the cam gear as with cheaper oil pumps. CB Oil Pumps are manufactured by an OEM supplier and feature full size 26mm gears. The pumps are assembled with closer tolerances than stock pumps to provide increased oil pressure during low speed operation. They slip right in and increase the life of your engine.

Maxi Pump 3 - The ultimate VW Bug or Bus oil pump. The Maxi 3 was designed to solve oil flow and cooling problems on 1968-71 VW bugs or buses. It provides a way to operate your engine "Full Flow" without the inconvenience and cost of drilling and tapping your engine case as in old-style "Full Flow" systems. Maxi Pump 3 fits between your engine case and the rear mount and provides both outlet and inlet for unrestricted oil flow. Maxi 3 is one in a family of high performance VW oil pumps. The Maxi pumps feature die cast pump housings. The aluminum alloy used in manufacture matches the temperature characteristics of the engine case to help reduce leaks and oil loss. The inner design includes a "pressure chamber" to smooth out the flow of oil. 9 tooth gears and blueprinted specs help provide an oil system that will greatly reduce oil temperature and increase engine performance. Fits Bugs and Buses!
