Pivot Bolt - Timing Chain Tensioner Blade is the shouldered fastener that locates the primary timing chain tensioner blade within the AJ-V8 front timing assembly.

It threads into the cylinder block face behind the timing cover and forms the pivot about which the tensioner blade swings, allowing the hydraulic tensioner to maintain constant tension on the primary chain as the chain and guides wear. Because it is reachable only with the front timing cover removed, it is normally handled as part of a timing chain overhaul rather than as a standalone job. The blade it pivots is NCA2025AB.

Supplied individually.

Frequently asked questions

What is the NCA2028AA pivot bolt?
The NCA2028AA is the pivot bolt for the primary timing chain tensioner blade on the Jaguar AJ-V8 engine. It holds the tensioner blade in place so it can bear against the timing chain. It's an OEM Jaguar part.
Which vehicles does this timing chain pivot bolt fit?
This pivot bolt fits the Jaguar S-Type (1999-2008) V8 and the Jaguar XJ (X308, 1998-2003) 3.2L and 4.0L V8. It's a Jaguar fitment only, with no Land Rover application.
Should this pivot bolt be reused during a timing job?
Timing chain fasteners like the NCA2028AA are typically renewed when the timing cover or tensioner is disturbed, since they can be torqued into a critical assembly. Fitting a new bolt is the safe choice during a timing chain repair.
