Intermediate Sprocket Tightening Sequence
Note
♦ Always replace the intermediate sprocket. Otherwise the
backlash will not adjust itself and it could result in engine dam‐
age.
♦ The new intermediate sprocket has an anti-friction coating that
wears off after a short period of use, which automatically ad‐
justs the backlash.

2. -1- The intermediate sprocket
must not have any play. Loos‐
en and tighten it again if nec‐
essary.

VW GOLF TIMING CHAIN
Note
♦ The painted links of the chain must be positioned on the mark‐
ings on the chain sprockets.
♦ Do not pay attention to the position of any additional painted
chain links that may also be present.
– Lay the balance shaft drive chain, and position the painted
links -arrows- with the markings on the chain sprockets.
– Install the guide track -1- and tighten bolts -arrows-.
– Engage the camshaft timing chain with the painted links
-arrows- on the camshaft pins.
– Lay the oil pump drive timing chain onto the three stage chain
sprocket.
– Tilt the three stage chain sprocket in the direction of the
-arrow- toward the engine and secure it to the crankshaft. The
marking -arrows- must be positioned opposite each other.
1. Install the Tensioning Pins – T10531/2- in the crankshaft and
tighten hand-tight.

the Adapter – T40266- until the Camshaft Lock – T40271/2-
-2- can be pushed out of the chain sprocket splines. Release
the camshaft.
– Remove the Camshaft Lock – Component 1 – T40271/1- and
Camshaft Lock – Component 2 – T40271/2- .
– Check the adjustment. The painted chain links -arrows- must
line up with the markings on the chain sprockets.
– Install the bolts -arrows- and tighten them. Tightening specification.
– Lubricate the holes -arrows- with engine oil.
Note
Adapter sleeve -1- is not present on every bearing bracket.
– Attach the bearing mount. Do not tilt it when doing this. Handtighten the bolts -arrows-.
– Remove the Tensioner Locking Tool – T40267- .
– Tighten the bearing bracket bolts -item 5-
– Install the pilot valves
– Let the engine turn a second time in the direction of engine rotation.
Note
Due to the ratio, the painted chain links no longer match up after the engine has been turned.
– Remove the turning over tool and install the lower timing chain
cover. Refer to ⇒ page 109 .
Note
Tighten the bolts -1 and 4- with an additional turn after installing
the vibration damper. The bolts must be removed again to install
