MITSUBISHI MAGNA TE 2.4L SOHC (4G64 16 Valve Engine) 1996 - 97 Timing Belt Installation
refer Timing Belt Diagram at bottom
Removal
1. Remove the front covers.
Do not remove the crankshaft centre bolt until the main belt has been removed.
2. Rotate the engine clockwise until all timing marks are aligned as per the diagram.
This may take up to 6 engine revolutions.
(#1 cylinder should now be at TDC on compression stroke)
3. Remove the blanking plug from the rear of the oil pump sprocket.
4. Insert an 8mm diameter rod (or screwdriver), 60mm into the hole.
If the Rod (or screwdriver) can only be inserted 20mm, rotate the crankshaft 360deg.
5. Remove tensioner "A".
6. Remove automatic tensioner and main belt.
7. Remove the crankshaft main bolt and pulley.
8. Loosen tensioner "B" locking bolt and lever the tensioner away from the belt.
9. Temporarily tighten tensioner pulley "B".
10. Remove balance shaft belt.
Installation
Two special tools are required for this job.
1. Required for tensioner pulley adjustment. (Mitsubishi Part # MD 998752)
2. Required for tensioner lever adjusting. (Mitsubishi part # 998738)
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.
1. All timing marks must be aligned.
2. Fit balance shaft belt and loosen the tensioner nut.
3. Fit main timing belt in the following order:
Crankshaft.
Oil pump / Balance shaft.
Guide.
Camshaft.
Tensioner.
4. Compress auto tensioner (in vise) and secure piston in body with a suitable pin.
Protect protruding plug at the base of the tensioner body from damage when compressing shaft.
5. Fit tensioner pulley and auto tensioner on main belt.(do not release locking pin).
6. Push tensioner pulley against the main belt and temorarily tighten the locking bolt.
(To hold the belt under some tension without the aid of the auto tensioner.)
7. Rotate engine anti clockwise 90°.
8. Rotate clockwise to TDC.
9. Tighten balance shaft pulley "B" and check deflection.
Counterbalance Shaft Belt Deflection.
Should be:
5 to 7 mm at point ‘A’ with 10 Kg load.
10. Loosen the main belt tensioner locking bolt.
11. Fit special tool to tensioner pulley "A".
12. Using special tool, apply a torque of 3.6 Nm anti clockwise.
13. Tighten tensioner "A" locking bolt.
14. Rotate engine clockwise two revolutions to TDC.
15. Wait for 15 minutes.
16. Measure how far the shaft on the auto tensioner extends from the tensioner body.
It should be:
3.8 to 4.5 mm.
If this measurement is not to specifications, repeat installation procedure.
If measurement is still not to specifications, suspect faulty auto tensioner.
Tightening Torques
Automatic Tensioner Bolts.
24Nm
Balance Shaft Sprocket.
57Nm
Camshaft Sprocket Bolt.

110-130Nm
Crankshaft Sprocket Outer Bolts.
20-30Nm
Oil Pump Sprocket Bolt.
55Nm
Main Belt Tensioner Bolt.
48Nm
Balance Shaft Tensioner Bolts.
19Nm
R&R Time
1.90 hours (Add 0.50 hour for vehicles with airconditioning and power steering).
