Change to Mechanical Belt Tensioner - Refer to Application Chart for model usage
Up to 2002 all Pumpe Duse engines used a HYDRAULIC timing belt tensioner covered by tools supplied in DT.VAG Timing Kit – DT.4638 Tensioner Locking Tool and DT.4637 Tensioner Adjuster.
From 2002 Pumpe Duse engines started to be fitted with a MANUAL belt tensioner
New Tensioner Tool for Mechanical Tensioners – DT.4640T7 Tensioner Locking Pin

IMPORTANT: Belt tension adjustment must only be carried out when the engine IS COLD
Using DT.4637 Tensioner Adjuster, turn tensioner roller anti-clockwise until DT.4640T7 Locking Pin can be inserted. Then turn clockwise until it reaches a
"stop". Tighten roller nut and remove old belt.
Fit new belt, ensuring taut on non-tensioned side and that camshaft sprocket is in position within elongated slots.
