Parts for your 2005 Mitsubishi Pajero-Oil pump

2005 Mitsubishi Pajero oil pump — what it does and when to service it

The 2005 Mitsubishi Pajero definitely uses an oil pump. This is documented in Mitsubishi Motors’ workshop manuals for the Pajero/Montero NM–NS era (Engine Lubrication sections), the 4M41 3.2 Di‑D and 6G7x V6 engine service manuals, and the Mitsubishi ASA electronic parts catalogue, all of which list a crankshaft‑driven oil pump assembly for 2005 Pajero variants.

On this model, the oil pump is a gerotor/trochoid type integrated into the front timing case and driven directly off the crankshaft. Its job is to pull oil from the sump through the pickup, push it through the filter, and feed critical parts like crank and cam bearings, hydraulic lifters, and—on the 3.2 Di‑D—its turbocharger. It also regulates pressure via an internal relief valve so the engine gets steady lubrication across cold starts, high revs, towing, or long highway runs in Aussie and Kiwi conditions.

This pump isn’t a routine replacement item
