MITSUBISHI MAGNA TE 3.0L V6 (6G72 Engine) 1996-97 Timing Belt Installation
MITSUBISHI MAGNA TF 3.0L V6 (6G72 Engine) 1997-99 Timing Belt Installation
MITSUBISHI MAGNA TH 3.0L V6 (6G72 Engine) 1999 Timing Belt Installation
(Suits models with Automatic Hydraulic Tensioner)
refer Timing Belt Diagram at bottom.
Removal
1. Remove Auxiliary Drive Belts.
2. Remove Upper Timing Belt Covers.
3. Remove Crankshaft Pulley.
4. Remove Lower Timing Belt Cover.
5. Temporarily refit Crankshaft Pulley.
6. Rotate Engine Clockwise until the Timing Marks are aligned as per the Diagram.
7. Rotate Crankshaft Anti-Clockwise 3 Teeth from the Timing Mark.
This avoids contact between the Valves and the Piston at TDC if the Camshafts turn.
8. If Timing Belt is to be re-used, mark direction of Rotation on Belt.
9. Remove Right Engine Support Bracket.
10. Remove Crank Angle Sensor.
11. Remove Automatic Tensioner.
12. Remove Timing Belt.
Camshaft Sprockets may turn due to Valve Spring Tension.
Installation
1. Place the Automatic Tensioner in a Vice.
2. Slowly compress the Piston into the Automatic Tensioner Body to align the Holes.
3. Insert a 1.4 mm Hex Key into the Holes to lock the Piston in place.
4. Install Automatic Tensioner.
5. Ensure the Crankshaft Sprocket Mark is 3 Teeth Anti-Clockwise from the Timing Mark.
6. Rotate the Camshafts slightly to align the Timing Marks and hold in position.
Camshaft Sprockets may turn due to Valve Spring Tension.
Be careful not to catch fingers if Camshafts turn.
7. Rotate the Crankshaft to align the Crankshaft Timing Marks.
8. Fit the Timing Belt in the following order: (Keep Belt taut when fitting)
Crankshaft
Idler Pulley
Front Camshaft
Water Pump
Rear Camshaft
Tensioner
9. Lightly press the Tensioner Pulley against the Timing Belt.
10. Temporarily tighten the Tensioner Pulley Centre Bolt.
11. Check Timing Marks are aligned.
12. Rotate Crankshaft Anti-Clockwise 90°.
13. Rotate Crankshaft Clockwise 90°.
14. Check all Timing Marks are aligned.
15. Loosen the Tensioner Pulley Centre Bolt.
16. Fit Mitsubishi Special Tool EMB998767 to the Tensioner Pulley.
To Fabricate Special Tool similar to Mitsubishi Part #MD 998738
refer diagram at bottom.
Weld the pins to the steel plate to correspond to the holes in the tensioner pulley.
Fit the plate to the pulley.
Hold the socket against the steel plate central to the tensioner pulley.
Mark and weld to steel plate.
An accurate torque measurement is not possible if the socket is not welded central to the pulley.
17. Apply a Torque of 4.4 Nm Anti-Clockwise to Special Tool to tension the Belt.
18. Torque the Tensioner Pulley Centre Bolt.
19. Rotate Engine Two Complete Turns Clockwise.
20. Check Timing Marks are aligned.
21. Allow to stand for 5 Minutes.
22. Remove the 1.4 mm Hex Key from the Automatic Tensioner.
23. Check the projection of the Automatic Tensioner Piston - should be 3.8 to 5 mm.
If the Hex Key cannot be removed easily or the Piston Projection is not as specified:
Repeat Installation Procedure from Step 16 to obtain the correct Timing Belt tension.
24. Re-fit Crank Angle Sensor.
25. Refit Lower Timing Belt Cover.
26. Refit Crankshaft Pulley.
27. Re-fit Right Engine Support Bracket and Torque Bolts in the correct sequence.
Torque sequence is Anti-Clockwise starting from the Bolt at the 12 O’Clock Position.
28. Re-fit Upper Timing Belt Covers.
29. Re-fit Auxiliary Drive Belts.
