Here's a new Timing Chain Kit for the following models from Triumph -

TRIUMPH

Triumph 1300FWD Saloon        (1965- 70)

Included in this kit are the following -

Timing Chain
Oil Seal for Timing Cover
Tensioner
Gasket for Timing Cover

(Your model must be listed here - there are variations. This is the kit with the earlier small oil seal - The external diameter of the seal is 6.0cm).

You need this kit for any engine rebuild, the oil seal will have gone hard and the timing chain will have stretched making it noisey and more likely to break.
