Achilles Motorsport Upgraded Oil Pump Shaft Kit - M54 M52TU

BMW M54 M52TU Oil Pump Drive Upgrade by Achilles

Protect your BMW straight six with a proven fix for the well-known oiling issue on M54 and M52TU engines. High rpm, resonance and torsional spikes can cause the factory drive to fail, which can instantly drop oil pressure. This Achilles kit replaces the vulnerable components with a far stronger, motorsport-grade solution that resists loosening and keeps your lubrication system secure on the road and on circuit.

We have installed this kit in-house and it does exactly what enthusiasts want from an upgrade. Rock solid at sustained rpm, confidence inspiring on track days, ideal for drift and fast road builds. Our customers love the peace of mind it delivers.

Why this upgrade

• Stops the common oil pump drive failure that leads to immediate pressure loss
• Track proven reliability for spirited use, endurance events, drift and high revving NA or forced induction builds
• Purpose designed to resist loosening where the OE arrangement can back off under resonance

Engineering highlights

• Heat treated chromoly steel shaft, precision ground for perfect concentricity and strength
• Square keyway interface with matching gear to prevent any chance of the gear slipping on the shaft
• Extended length left hand thread securing bolt, EDM cross drilled, supplied with safety wire for proper locking
• High tensile hardware to secure the drive gear to the shaft
• Fully serviceable and rebuild friendly, no grinding required when overhauling

Who is it for

Ideal for anyone building or maintaining a BMW M54 or M52TU powered car who wants a belt and braces solution for oil pressure security. Perfect for track day cars, drift cars, endurance and road cars that regularly see the top of the rev range.

Installation

Professional fitting is essential. The shaft must be pressed into the oil pump inner rotor and the safety wire installed correctly. For installation, we recommend booking with MJ Modifications in Warwickshire. Request a fitting quote at info@mjmodifications.co.uk.
