How to Adjust the Timing Opel Omega B

DOHC Diesel Engine 4 illustrations ~394 words

Note. Before adjusting the timings, the timings must be checked – see operation "Timing, Check".

Engine is locked in 1st cylinder ign. TDC position with KM-813 .

Remove

  1. 1. Remove vacuum pump – see operation "Vacuum Pump, Remove and Install".
  2. 2. Remove torx bolts (1) and (2), then insert new torx bolts – when releasing, counterhold at hex on camshafts.

Install

  1. 3. Screw in torx bolts to the stop – it must still be possible to twist the sprockets toward the camshaft.

Adjust

  1. 4. Position peg gauge (2) from KM-6267 onto intake camshaft (1) and align intake camshaft until peg gauge rests on cylinder head without any gap (arrows).
  2. 5. Secure peg gauge from KM-6267 with hold-down positioner from KM-6267 .
  3. 6. Tighten Torx bolt (5) for intake camshaft sprocket – counterhold at hex of intake camshaft – tightening torque 20 Nm /15 lbf. ft. + 35°.
  4. 7. Position peg gauge from KM-6267 onto exhaust camshaft (3) and align exhaust camshaft until peg gauge rests on cylinder head without any gap.
  1. 8. Secure peg gauge from KM-6267 with hold-down positioner from KM-6267 .
  2. 9. Tighten torx bolt (4) for exhaust camshaft sprocket – counterhold at hex of exhaust camshaft – tightening torque 20 Nm / 15 lbf. ft. + 35°.
  3. 10. Take peg gauge (1) from KM-6267 off exhaust camshaft. Remove, detach
  4. 11. Pull KM-813 (2) out of bore in drive disc / flywheel.

Adjust

  1. 12. With KM-6269 at torsional vibration damper hub, turn crankshaft 720° in engine rotational direction until KM-813 latches into bore for drive disc / flywheel.

Important. Important:

  1. 13. Ensure that for vehicles with automatic transmission, the test drift does not latch into the depressions in the fastening bolts of the converter.

Inspect

  1. 14. Position peg gauge from KM-6267 on intake camshaft and exhaust camshaft – peg gauge from KM-6267 must rest against cylinder head (arrows) without any gap.

Note. If peg gauge from KM-6267 does not rest on cylinder head without any gap, the operation must be repeated.

Remove

  1. 15. Detach peg gauge and hold-down positioner from KM-6267 .
  2. 16. Pull KM-813 out of bore in drive disc / flywheel.

Install

  1. 17. Attach closure plugs to cylinder block.
  2. 18. Install vacuum pump – see operation "Vacuum Pump, Remove and Install".
  3. 19. Install cylinder head cover – see operation "Cylinder Head Cover, Remove and Install".
