Genuine Mazda Oil Pump Drive Chain – MX-5 Mk3 / NC • LF01-14-151

Genuine Mazda LF01-14-151 Oil Pump Drive Chain

Replacement Genuine Mazda internal oil-pump drive chain for Mazda MX-5 Mk3, Mk3.5 and Mk3.75 / NC models fitted with applicable 1.8L and 2.0L petrol engines listed in the compatibility table.

The chain forms part of the engine’s internal lubrication-system drive and transfers crankshaft rotation to the oil-pump sprocket.

This allows the oil pump to circulate pressurised engine oil through the crankshaft bearings, connecting-rod bearings, cylinder head, camshaft system and other lubricated engine components.

Correct oil-pump drive is essential for maintaining engine oil pressure and protecting internal components against excessive friction, heat and wear.

Replacement may be required where the original chain is stretched, worn, damaged or producing excessive mechanical noise, or during an engine rebuild or oil-pump repair.

This listing supplies one Genuine Mazda oil-pump drive chain, which is the quantity required per applicable engine.

• Part type: Engine oil-pump drive chain

• Primary function: Transfers crankshaft rotation to the engine oil pump
• System: Engine lubrication system
• Fitting position: Internal lower front section of the engine
• Primary vehicle application: Mazda MX-5 Mk3, Mk3.5 and Mk3.75 / NC
• Engine applications: Applicable 1.8L L8-DE and 2.0L LF-VE petrol engines
• Transmission applications: Manual and automatic according to vehicle specification
• Quantity required per engine: One
• Quantity supplied: One oil-pump drive chain

Typical reasons for replacement:

• Oil-pump chain stretched or excessively worn
• Excessive mechanical noise from the lower front of the engine
• Chain links damaged, tight or unevenly worn
• Oil-pump sprocket or crankshaft drive components being replaced
• Oil pump being removed or overhauled
• Engine being rebuilt
• Chain contaminated by internal engine damage or metallic debris
• Unknown chain condition following a lubrication-system failure

Fitment advice: This chain is used in the internal oil-pump drive fitted to applicable Mazda MX-5 NC 1.8L and 2.0L MZR petrol engines.

Reference advice: Mazda catalogue systems also associate 1F20-14-151 and 1F20-14-151A with LF01-14-151. These references may appear in regional catalogues or on related Mazda applications.

Oil-pump advice: Inspect the oil pump for scoring, excessive internal clearance, pressure loss or damage before fitting the replacement chain. A new drive chain will not correct a worn or defective pump.

Sprocket advice: Inspect the oil-pump and crankshaft drive sprockets for hooked, sharpened, chipped or unevenly worn teeth. Installing a new chain onto worn sprockets can cause accelerated wear and poor engagement.

Guide and tensioning advice: Inspect all associated chain guides, tensioning components and mounting hardware. Worn or damaged components may allow excessive chain movement or noise.

Oil-pressure advice: Low oil pressure can also be caused by insufficient oil level, incorrect oil viscosity, a blocked pickup strainer, worn bearings, damaged seals or excessive oil-pump clearance. Diagnose the complete lubrication system rather than assuming the chain is the sole cause.

Contamination advice: Where the chain is being replaced following internal engine damage, thoroughly clean the sump, oil pickup, oil galleries and related components to remove metallic debris and contaminated oil.

Sealing advice: Access normally requires removal of major lower-front engine components and resealing of disturbed covers or sump sections. Use the specified Mazda-compatible sealant and follow the prescribed bead pattern and curing instructions.

Engine-timing advice: The oil-pump chain is separate from the main camshaft timing chain. Maintain the correct position of all crankshaft, timing and balance-related components during disassembly and reassembly.

Lubrication advice: Lubricate the replacement chain and sprocket contact surfaces with clean engine oil during assembly. Do not start the engine with dry oil-pump drive components.

Priming advice: Prime the lubrication system according to the applicable Mazda workshop procedure before initial start-up. Confirm that oil pressure is established promptly and investigate immediately if the warning lamp remains illuminated.

Other items to consider: Consider inspecting or replacing the oil pump, oil-pump sprocket, crankshaft sprocket, chain guides, pickup-pipe seal, sump sealant, front crankshaft seal, engine oil and oil filter according to their condition.

Useful tools / consumables: Engine-support equipment where required, socket and spanner set, crankshaft-pulley holding tools, torque wrench, suitable pullers, gasket scraper, Mazda-compatible sealant, assembly lubricant, fresh engine oil and a new oil filter.

Difficulty guide: DIY Difficulty: Advanced. Installation requires substantial engine dismantling, accurate component positioning, careful sealing and correct tightening of internal engine fasteners.

Why Genuine Mazda? Genuine Mazda oil-pump drive components are manufactured to the intended chain pitch, link geometry, width and sprocket engagement requirements. Using the correct OE chain helps maintain reliable oil-pump drive and compatibility with the original lubrication system.

What’s in the box: One Genuine Mazda oil-pump drive chain, part number LF01-14-151. Oil pump, sprockets, guides, tensioning components, seals, gaskets, sealant and mounting hardware are not included unless specifically shown or stated separately.

Installation notes: Drain the engine oil and follow the applicable Mazda workshop procedure for accessing the internal oil-pump drive. Secure the engine as required, remove the obstructing covers and lower-engine components, and record the original chain and sprocket arrangement. Inspect all drive components, install the replacement chain with the correct alignment and tighten all fasteners to specification. Reseal disturbed joints, refill with the correct engine oil and prime the lubrication system before starting the engine.
