8472KIT x 1. This is a new pulley kit suitable for use on the Later spec Jaguar XK150, which uses the heavier duty 1/2" (13mm) fan belt system, and is excellent to upgrade other XK models to the stronger fan belt that uses the dynamics of a smaller pulley to upgrade the charging system too (known as over-running).

This Kit includes a new cast aluminium crankshaft pulley & water pump pulley (as originals do wear away) and the steel (was originally cast iron) smaller diameter XK150 dynamo pulley and correct XK150 length fan belt to suit. 

This complete setup will interchange onto XK140 and XK150 early spec. 10mm wide belt systems if you wish to upgrade. A very good upgrade for the  XK120 if you have a later pump fitted as it deletes the obsolete 20mm belt and pulleys and over-runs the dynamo for better charging too.

NOTE: We can also substitute the Dynamo Pulley for one with a 0.595" dia hole for fitting to a Lucas ACR Alternator. State when ordering to change to a : SE336P pulley.

The part reference for this crank pulley is 8472, the pump pulley is 8474, the dynamo pulley is 8479, and 13mm fan belt is 8024.
