Information
Chain tensioner adjuster.
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
