This is our world renown Hydraulic Timing Chain Tensioner Kit for the XK120 and also Early XK140 version engines that used a spring blade type chain damper. It replaces the C2156 / C4100 / C8245 tensioner blades and C2284 / C4100 springs, which are prone to wearing completely through and dropping into the bottom of the timing chest at the front of the engine. This kit is based on the original, Jaguar Racing Division's racing conversion for these series engines as used in XK powered race cars such as the iconic C-Type Jaguar in the 1950's. The original was cast, but a solid block is more reliable as it will be far less likely to have faults in it that could cause failure

The oil spray bar is removed and the oil flow from this point is re-routed to a later XK150 type hydraulic (self adjusting) damper assembly C10332 (and it is advised to have the conical filter fitted behind to prevent oil blockage). So no more rattling timing chain........ ever,  after you fit this very popular and effective conversion. 

As adapter is a brass block, it will require fettling at the back, as shown, to fit the various different engine castings that Jaguar evolved during this early period of the XK engines long life. We cannot accept kits back after they have been fitted or modified for fitting, so make sure you have someone competent to fit it properly. This kit consists of : damper, adaptor block, bolts, gasket and fitting instructions.

You will see this re-sold in many places, marketed under lots of companies own names. Here you are dealing directly with the actual first line manufacturer, supplier and specialist to ensure you get the all right parts, proper fitting information and back-up advice!

If you want to cure the other XK120 main engine fault, see our XK120 Front Crankshaft Seal Conversion Kit ( SE823)  - to cure the annoying oil drips from the old style 2-piece front rope seals!

This part number is SE822. Original Jaguar part number is not relevant as this was a later modification.
