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.

The OE Match timing chain adjuster (also known as a chain tensioner adjuster) is an engine timing component used in Porsche 964 and Porsche 993 models. These adjusters help maintain the correct tension in the engine’s timing chain system, ensuring accurate synchronization between the crankshaft and camshafts.
Fits:
Porsche 964 1989 - 1994
Porsche 964 Turbo 1993 - 1994 3.6L
Porsche 964 RS
Porsche 993 1994 - 1998
Diagram Ref no 9 and 10.
The OE Match versions correspond to Porsche reference numbers 96410507900 / 96410507901 (left side) and 96410508000 / 96410508001 (right side) and are designed as direct replacements for the original factory components.
The timing chain adjuster is part of the camshaft timing system used in air-cooled Porsche flat-six engines. The component works together with the timing chain tensioner and guide rails to keep the chain correctly tensioned as the engine operates.
Each engine uses separate left and right adjusters, depending on the cylinder bank.
The chain adjuster maintains the proper position and tension of the timing chain, preventing slack or vibration within the timing assembly. By keeping the chain properly tensioned, it helps ensure precise valve timing and smooth engine operation.
Replacing worn adjusters helps prevent timing chain noise, improves reliability and protects critical engine components from excessive wear.
Function
• Timing Chain Tension Control: Maintains proper tension in the camshaft timing chain
• Valve Timing Accuracy: Ensures correct synchronization between crankshaft and camshafts
• Engine Protection: Prevents chain slack, vibration and premature wear
• Smooth Operation: Helps eliminate chain rattle and timing instability
Timing components are constantly exposed to engine heat, oil pressure and mechanical load. Over time adjusters can wear or lose precision, leading to timing chain noise, unstable valve timing or reduced engine performance. Replacing worn chain adjusters ensures proper tensioning of the timing chain and helps protect the engine’s internal components.
Consider replacing the timing chain adjuster when:
• Timing chain rattle or knocking noise appears
• Performing timing chain or tensioner replacement
• During engine rebuild or top-end service
• High-mileage engines with original timing components

The camshaft timing chain is a critical engine component that maintains precise timing between the crankshaft and camshaft(s). This timing governs when the engine’s intake and exhaust valves open and close relative to piston position - a key factor in efficient combustion, engine power, emissions, and overall drivability. The chain connects the rotating crankshaft to the camshafts so that valve timing is mechanically linked and constant.
Function:
• Synchronises engine timing: Maintains crankshaft-to-camshaft rotation alignment
• Supports combustion efficiency: Ensures accurate valve events for intake and exhaust strokes
• Transfers mechanical drive: From crankshaft to camshaft drive mechanisms
• Withstands high loads: Engine torque and RPM forces over long service life.
Unlike timing belts, timing chains are metal-to-metal and designed for durability, although they can stretch or wear with high mileage or inadequate lubrication.
The timing chain is at the heart of the engine’s mechanical timing system. While chains are generally long-lasting, wear can occur due to mileage, heat cycling, lubrication contamination, or slack from chain stretch. A worn or stretched timing chain can lead to:
• Incorrect valve timing
• Engine noise (rattle at startup or idle)
• Reduced power and efficiency Irregular idle and misfires
• Potential catastrophic engine damage if timing deviates too far.
Replacing a worn chain with an OE Match unit restores correct timing precision and helps protect major internal engine components.
When to replace. Install a new timing chain when:
• There is timing chain noise (rattling) at startup or idle
• Chain tensioner or guides are being replaced
• Engine has high mileage with original timing components
• You are performing engine rebuild, top-end service, or head removal
• Diagnostic codes indicate timing inconsistencies
