BMW M54 / M52TU Oil Pump + Drive Shaft Upgrade  -  Complete Ready-to-Fit brand new pump

The BMW M54 / M52TU oil pump drive is a known weak point: vibration/harmonics can work the drive fastener loose and in worst cases lead to drive failure and instant oil pressure loss.
Our solution addresses the two things that matter most for reliability: positive drive engagement and secure, fail-safe retention but with one major advantage: we supply a brand pump that’s ready to install not just loose parts.

What makes our solution different?

Many kits on the market supply only a upgraded shaft and sprocket leaving you to:

 * Press parts together
 * Torque the left hand bolt

This is a ready-to-fit oil pump assembly with the upgraded drive already built in so installation is straightforward while you already have the sump off.

Key features of this oil pump shaft upgrade:

* Double “D” drive shaft design to reduce the chance of slip under vibration.
* Left-hand thread drive bolt (correct direction for this application) to resist loosening tendencies associated with rotation and vibration.
* Wire-EDM drilled bolt to allow mechanical locking (safety wire) as a secondary retention method because thread direction alone isn’t enough in a high-vibration environment.
* Pre-assembled and ready to install: sprocket is torqued to specification and assembled using high-strength thread locker.

Why “ready to fit” matters?

With oil pump drive issues the details are everything: press fit, alignment, correct torque and proper locking. A complete, pre-built pump removes common installation variables and saves time especially if you’re doing this preventatively during an oil pan gasket baffle install or track-prep service. 

Result: a clean, professional upgrade path that’s engineered to reduce the risk of oil pump drive failure and the catastrophic oil pressure loss that can follow.
