Diagram Ref No 9

The oil pump must operate whenever the engine is running to circulate lubricant through the engine. This chain forms part of the mechanical drive system that keeps the pump operating, supporting lubrication of bearings, crankshaft components, camshaft and valvetrain parts, timing components and other moving internal surfaces.

Although designed for extended service life, an oil pump drive chain is subjected to continuous mechanical loading, friction and heat. Wear to the chain links, pins and associated sprockets can gradually increase chain slack and reduce the reliability of the drive system.

What This Product Does:
The oil pump chain transfers mechanical rotation through the engine's oil pump drive system, allowing the oil pump to operate continuously while the engine is running.

Reliable pump operation allows engine oil to circulate to critical components including:

• Crankshaft bearings
• Connecting-rod bearings
• Camshaft components
• Valvetrain components
• Timing chains and sprockets
• Timing guides and tensioners
• Other internal moving and friction surfaces

The chain itself does not generate engine oil pressure. It provides mechanical drive to the oil pump; the pump and lubrication system are responsible for producing, regulating and distributing the required oil flow and pressure.

Symptoms Of Wear Or Failure:
Possible symptoms of deterioration within the oil pump chain or associated drive components include:

• Metallic rattling or clattering
• Mechanical chain noise
• Rattle during engine start-up
• Noise that changes with engine RPM
• Excessive chain slack
• Chain elongation
• Excessive chain movement
• Visible wear to chain links or pins
• Abnormal sprocket wear
• Worn or damaged guides, where fitted
• Excessive tensioner travel, where applicable
• Metal or plastic debris in the engine oil
• Wear debris in the oil filter
• Oil-pressure warning light
• Low oil-pressure warning
• Oil-pressure-related diagnostic faults
• Increased mechanical engine noise associated with inadequate lubrication

A low oil-pressure warning does not automatically indicate a failed oil pump chain. Low oil level, oil pump wear, a restricted pickup, pressure-control problems, incorrect oil, excessive bearing clearance or an oil-pressure sensor fault can produce similar symptoms.

Why Replacement Matters:
The Oil Pump Timing Chain performs a critical mechanical function within the engine lubrication system.

Replacing a confirmed worn, elongated or damaged chain can help:

• Restore reliable oil pump drive
• Maintain dependable engine oil circulation
• Reduce excessive chain slack
• Reduce abnormal mechanical noise
• Restore reliable sprocket engagement
• Protect associated sprockets
• Protect guides and tensioning components
• Reduce the risk of chain derailment
• Reduce the risk of chain breakage
• Support correct engine lubrication
• Protect bearings and other internal components
• Reduce the risk of lubrication-related engine damage

Because the engine depends on continuous oil circulation, a confirmed fault within the oil pump drive system should not be ignored.
