The M54 engine has well-documented issues caused by harmonics. The extreme vibrations cause the weak oil pump shaft to shear off or the oil pump nut to come loose and fall off, all of which results in an instant loss of oil pressure. Achilles Motorsports decided to develop a solution to fix all of these known issues. Achilles takes their oil pump shafts to the extreme, using only the toughest materials and heat treatment processes to ensure optimum strength. The core of this kit is a hardened Chromoly shaft that is centerless ground to ensure absolute trueness. The shaft is engineered with an exclusive square key lock system that not only prevents the gear from ever spinning on the shaft but also adds strength to the area to which the gear mounts. Achilles Motorsports then replaced the pesky oil pump nut with an extended length bolt that is EDM drilled for safety wire to properly secure it for all conditions. Don't wait for your oil pump to fail and leave you stuck with costly engine repairs! Key Features: Hardened Chromoly centerless ground shaft EDM Drilled Bolt with a piece of safety wire included Grade 8 extended length hardware to secure the gear to the shaft Left hand threaded to prevent it from unexpectedly coming loose Exclusive Square key lock shaft and drive gear 100% serviceable & rebuildable without the need for grinding NOTE: Professional installation required! The shaft requires being pressed into the oil pump's inner rotor.

This pump features two important upgrades: This pump is engineered with VAC's famous Oil Pump Upgrade kit integrated in its design; this means a stronger gear drive mechanism for much lower likelihood of pump failures on the track. VAC has not only improved the physical reliability of the pump itself but also fit a custom gear with a larger sweep area to the pump mechanism, increasing volume by a welcome 22% An excellent upgrade for Road Race, Autocross, Time Attack, Drift, Hill Climb, Rally, Drag Race, Roll Race & forced induction applications. Lubrication issues are a common killer of BMW engines. The dual-pickup pump is much better than a standard single pickup, but this pump is a dramatic improvement over both.

Achilles Motorsports' S54 Swap oil pump upgrade kit is designed to work with late-model M50/S52 generation oil pumps. This is a typical conversion when retrofitting an S54 engine into a chassis such as an E30 or E34 that requires the use of a front sump oil pan. This kit can also be used to upgrade the Euro S50B30 3.0L Single Vanos engine oil pump to the later generation pump utilizing a higher volume pump. The ULTIMATE SOLUTION for your S54 Swapped car offered by Achilles Motorsports! Achilles takes their oil pump shafts to the extreme, using only the toughest materials and heat treatment processes to ensure optimum strength. The core of this kit is a hardened Chromoly shaft that is centerless ground to ensure absolute trueness. The shaft is engineered with an exclusive square key lock system that not only prevents the gear from ever spinning on the shaft but also adds strength to the area to which the gear mounts. Achilles Motorsports then replaced the pesky oil pump nut with an extended length bolt that is EDM drilled for safety wire to properly secure it for all conditions.

The M50/M52/S50/S52 engines are notorious for their well-documented problems stemming from harmonics. The vibration leads to the oil pump shaft becoming weak, causing it to either break or the oil pump nut to loosen and fall off, resulting in an immediate loss of oil pressure. Worry no more! 5150 has the solution! At the core of this kit is a hardened Chromoly shaft, meticulously centerless ground to guarantee absolute precision. This shaft is designed with an exclusive square key lock system, which not only prevents the gear from ever rotating on the shaft but also reinforces the mounting area, adding additional strength. Furthermore, we replaced the problematic oil pump nut with an extended-length bolt, which is EDM drilled to accommodate safety wire for a secure fit in all conditions. Don't wait until your oil pump fails, leaving you facing expensive engine repairs! Key Features: Centerless ground shaft made from hardened Chromoly. Bolt with EDM drilling, including safety wire. Grade 8 extended-length hardware for secure gear attachment. Left-hand threaded to prevent unexpected loosening. Double-D keyed shaft and drive gear. Fully serviceable and rebuildable without the need for grinding.
