Oil Pump

A drop in oil pressure can spell disaster at the wrong time. Although most modern BMWs do not have an oil pressure gauge, the DME continually monitors internal pressure and will let you know if there is a problem with the pump.

Prevent costly failure with this IWIS Engine Oil Pump Chain Kit! This kit contains all of the basic items needed to service your oil pump drive system and prevent failure long before it occurs. Chains can stretch and chain guides and tensioners can wear out, leading to the chain skipping teeth. This prevents the oil pump from being driven at the proper speeds. If not addressed, the chain could begin to "slip" over the gears, failing to drive the oil pump. When this occurs, oil pressure will drop suddenly, failing to properly lubricate sensitive internal engine components such as main bearings, rod bearings, and camshaft ledges and lobes, resulting in severe scoring and eventual engine failure.

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.
