The cam lobe will rise, Fig. 3 and the DTI will return to the zero datum point and continue to the correct nominal value of 0.55 +/- 0.03mm.
WARNING: If the nominal value is not obtained, cam timing must be adjusted.
Fig.3
Adjusting Timing
Counter-hold the camshaft using a spanner on its 22mm hexigon whilst releasing the camshaft sprocket bolt,
allowing the sprocket to be 'free to turn' on the camshaft.
WARNING: Ensure crankshaft position remains fi xed.
DT.4130 Plate remains pushed to the left in its left stop position with the dial test indicator resting on the cam lobe,
as Fig. 3. Turn camshaft carefully, with spanner in the normal engine direction, until the dial test indicator reads approx. 0.80mm.
Use the spanner to turn the camshaft in opposite direction of normal rotation until dial test indicator gives a reading of 0.60 – 0.64mm.
Remove DT.4130 ensuring the DTI position within the Plate is not altered.
Secure the camshaft in this position whilst fi tting a new sprocket bolt and tighten to specifi ed torque.
WARNING: DO NOT allow the camshaft position to change.
Remove all tools and rotate crankshaft 2 times and return to TDC position
Install DT.4130 Plate in its left stop position with DTI resting on cam lobe to check that the correct timing nominal value of 0.55 +/- 0.03mm. has been achieved.
Crankshaft Timing
DT.4149 Flywheel TDC Setting Tool
(X17DTL engines –97) – Refer to Application Chart
DT.4149 Setting Tool is essential to determine the fl ywheel/crankshaft TDC position
and is attached to the fl ywheel housing to provide the 'pointer' position on which
to align the TDC mark on the fl ywheel.
DT.4298 Flywheel Locking Pin (X17DTL engines 97-) – Refer to Application Chart
DT.4298 is used in place of DT.4149 Setting Tool on the later engines having two-part oil pan. It is inserted through
a hole in the gearbox bell housing and locks the fl ywheel/crankshaft at TDC position.
The crankshaft is carefully turned in the normal direction of engine rotation, until DT.4298 can be located
into the fl ywheel. DT.4298 Pin is supplied with a retaining spring. This is attached to a nearby bolt
to retain the pin in its hole during work on the engine.
DT.3054/14 Injection Pump Locking Pin (X17DTL engines 98-) – Refer to Application Chart
From MY98 onwards, the injection pump sprocket provides a datum hole to establish pump timing.
When renewing the timing belt, the pump sprocket retaining bolts are slackened and timing position
established using DT.3054-14 Locking Pin.
DT.4150 Flywheel Holding Tool
Locking Pins or Bolts MUST NOT be used to counter-hold the crank or cam whilst releasing or tightening
the crankshaft pulley – use Holding Tool DT.4150 to secure the fl ywheel in place during this application.
X20DTL/DTH / X22DTH / Y20DTL/DTH / Y22DTH
CHAIN DRIVE Di diesels
These Opel 2.0 and 2.2Di diesel engines require the following tools from DT.OPEL Timing Kit -
DT.4481 Camshaft Setting Tool
DT.4482 Crankshaft Locking Pin
DT.4483 Injection Pump Locking Pin
DT.4484 Timing Adjustment Assembly
The correct engine 'timing' position will need to be re-established whenever service work requiring cylinder head removal, camshaft/valve train
adjustment, or major engine repairs have been carried out – see "Timing Adjustment".
IMPORTANT: With the 1 cylinder at TDC, the timing position is correct only when the Crankshaft Pin, Injection Pump Pin and Camshaft Setting Tool can all be installed on the engine.
