Frequently asked questions

What does the AJ813898 primary timing chain tensioner do?
The AJ813898 primary timing chain tensioner keeps correct tension on the primary timing chain. It takes up slack as the chain wears and damps chain oscillation to keep valve timing accurate. Fitted to Jaguar 3.0L supercharged V6 (AJ126) and 5.0L V8 (AJ133) petrol engines.
Which Jaguar engines and models use this tensioner?
This primary timing chain tensioner fits Jaguar AJ126 3.0L supercharged V6 and AJ133 5.0L V8 petrol engines, used in XF 2009 on, XE 2015 on, XJ 2010 on, F-TYPE 2014 on and F-PACE 2016 on. Confirm the engine with your VIN, as tensioner design can vary by build.
What are the symptoms of a worn timing chain tensioner?
A worn primary timing chain tensioner typically causes a rattle from the timing cover on start-up or under load, and can trigger camshaft correlation fault codes on Jaguar AJ126 and AJ133 engines. Left unchecked, a failing tensioner risks chain slap and timing errors, so it's usually replaced with the chain kit.
