Genuine Mazda Oil Pump Drive Chain • LF01-14-151

Genuine Mazda LF01-14-151 Oil Pump Drive Chain

Replacement Genuine Mazda oil pump drive chain for Mazda MX-5 Mk3, Mk3.5 and Mk3.75 / NC models fitted with the 1.8L L8-DE or 2.0L LF-VE petrol engine from 2005/2006 to 2015 listed in the compatibility table.

The chain forms part of the engine's internal oil-pump drive system. It transfers rotation from the crankshaft-driven assembly to the oil-pump sprocket, allowing the oil pump to circulate pressurised engine oil through the lubrication system.

Reliable oil-pump drive is essential for maintaining lubrication to the crankshaft bearings, connecting-rod bearings, camshafts, timing components and other internal moving parts.

This listing supplies one Genuine Mazda oil pump drive chain. One chain is fitted per engine.

Replacement may be required where the original chain has stretched, developed excessive free movement, suffered damaged links or become contaminated by debris following an internal engine failure. Possible signs can include abnormal mechanical noise from the lower timing area, visible chain wear or damage found during oil-pump or timing-cover repairs.
