Injection Pump Locking Pins
3&4
DT.3054V3 and DT.4440V2
- Refer to Application Chart for model usage
Locking Pins are designed to pass through datum holes in the sprockets into fixed holes on the engine.
DT3054V3 is the larger diameter of the two locking pins and is used on engines having a One Piece Injection Pump Sprocket.
DT.4440V2 is used when 2-Part Sprockets are fitted (Sprockets with three retaining bolts securing a front sprocket to a rear mounting).
Tensioner Adjustment
5
DT.4444 Tensioner Adjuster
The tensioner roller has two holes into which the two "pegs" of DT.4444 locate to allow the tensioner to be turned to apply tension to the timing belt.
Section 2:
Pumpe Düse (Unit Injection)
DIESEL ENGINES
VAG Pumpe Düse diesel engines use a constant pressure fuel pump and each of the injectors are operated directly by the camshaft.
Crankshaft Position
6
DT.4636 Crankshaft Locking Tool
The crankshaft is turned clockwise to TDC position so that the timing marks align correctly.
The crankshaft gear is the 'locked' in this position using DT.4636 Locking Tool. The tool slides into the gear teeth from the front and locates into the hole in the oil seal
housing.
7
IMPORTANT: The timing mark "arrow" on the DT.4636 Locking Tool must align with the mark on the crank gear. Temporarily remove the plastic knob off the tool to
improve visibility.
Camshaft Timing
8
Timing mark alignment for the camshaft.
The notch of the camshaft sprocket hub (located behind the sprocket teeth), should align with mark on the casting – "3Z" (on left) for ANY & AMF engines, or with
"4Z" (on right) for the other Pumpe Düse engines listed in the Application Chart. Lock the camshaft in position by inserting DT.4440V2 Pin through elongated hole
on the left-hand side of sprocket.
Tensioner Tools
9
DT.4638 Tensioner Locking Tool
Use a suitable allen key locate onto the tensioner and depress the tensioner until DT.4638 Locking Tool can be inserted to retain the plunger.
Remove the tensioner device and timing belt together.
10
DT.4637 Tensioner Adjuster
Locate DT.4637 Adjuster into the two holes in the tensioner roller and turn clockwise until pointer (1) comes to a stop at position (2).
Re-install the tensioner device and fit new timing belt. Turn the tensioner roller anti-clockwise, using DT.4637 Adjuster, back towards position (3) until the DT.4638
Locking Tool can be easily removed.
Set the gap on the tensioner at position (A) as follows:-
ANY & AYZ engines to 7mm +/- 1mm.
Other Pumpe Düse engines on Application Chart to 4mm +/- 1mm.
