This puller is for removing the camshaft sprockets on all V6 Audi/VW engines (early 2 valve AND later 5 valve per cyl. engines but not VR6.) and V8 Audi and VW engines. Essential for a proper timing belt replacement on these engines. Not for 3.0 liter V6. Also useful for removing the injection pump sprockets on all VW/Audi Diesels up to mid 1999 (A1, A2 & A3 chassis G/J/NB, and B4 chassis Passats). Durable, heat treated arms and jackscrew.
