Section 4:
VAG PETROL ENGINES
Twin Cams – 1.4 & 1.6 16v.
Refer to Application Chart for model usage
These engines have a main drive belt (crankshaft to inlet camshaft), and a separate exhaust camshaft drive belt (from inlet to exhaust camshaft).
15
DT.4635 Camshaft Setting Tool
Dependent upon engine type (see above diagram), DT.4635 Setting Tool is used either as an assembly of the two pins and a bridge piece or as the two pins only
(without the bridge).
Check that the camshaft sprocket setting holes are in correct position to accept the tool or pins. (see above diagram).
16
Ensure that DT.4635 Setting Tool is installed correctly – insert the pins fully into the sprocket locking holes and then slide the bridge piece down to rest on the
sprockets. When correctly installed the two balls on the ends of the pins should be parallel.
Tensioner Tools

DT.4440T1 and DT.4593E1
DT.4440T1 Retainer and DT.4593E1 Pin are used to compress and 'lock' the timing belt tensioner on
V W 1.8 petrol engines.
DT.4440T1 is fitted and applies pressure to the plunger to release tension off the belt.
DT.4593E1 Pin is then inserted to 'lock' the plunger in the retracted position.
