Timing Belt Installation

Install the No. 1 belt idler with the 3 bolts.

Torque:

for bolt A:

44 N*m{449 kgf*cm, 32 ft.*lbf}

for bolt B, C:

19 N*m{195 kgf*cm, 14 ft.*lbf}

HINT:

1. The bolt lengths for bolt A, B and C as follows.
   
2. Bolt C is combined with the No. 1 timing belt idler.
   

Standard Bolt:

Item	Length
A	76.5 mm (3.01 in.)
B	42.9 mm (1.69 in.)
C	41.3 mm (1.63 in.)

Using the crankshaft pulley bolt, align the groove of the crankshaft pulley with the timing pointer by turning the crankshaft clockwise.

NOTICE:

Do not turn the crankshaft pulley counterclockwise.

Set the timing and drive pulleys at each position.

NOTICE:

1. Make sure the engine is cold.
   
2. When turning the crankshaft or camshaft, the valve heads will hit against the piston top. Do not turn them more than necessary.
   

Remove any oil or water on each pulley, and keep them clean.

Install the timing belt to the crankshaft timing and timing belt idlers.

Using SST, slightly turn the injection pump drive pulley clockwise. Install the timing belt to the pulley, and align the timing marks of the drive pulley and timing belt case.

Check that the timing belt has tension between the injection pump drive and camshaft timing pulleys.

Install the timing belt to the No. 1 timing belt idler.

Loosen the No. 1 timing belt idler bolt (A), and stretch the timing belt.

Slowly turn the crankshaft pulley.

NOTICE:

Always turn the crankshaft clockwise.

Tighten the No. 1 timing belt idler bolt.

Torque:

44 N*m{449 kgf*cm, 33 ft.*lbf}

Slowly turn the crankshaft pulley 2 revolutions from TDC to TDC.

NOTICE:

Always turn the crankshaft clockwise.

Check that the timing marks for each pulley align as shown in the illustration.
If the timing marks do not align, remove the timing belt and reinstall it.

Install the timing belt guide with the cup side facing outward.

Install 2 new gaskets to the timing belt cover.

Install the timing belt cover with the 11 bolts and washers.

Torque:

for bolt A:

8.5 N*m{85 kgf*cm, 75 ft.*lbf}

except bolt A:

11 N*m{107 kgf*cm, 8 ft.*lbf}

Install the idle pulley bracket with the 2 bolts.

Torque:

29 N*m{300 kgf*cm, 22 ft.*lbf}

Align the key groove of the pulley with the pulley set key, and slide the pulley onto the crankshaft to install it.

Using SST, install the pulley bolt.

Install the fan shroud (LandCruiser RM00000144D02KX.html).

Warm up the engine.

When using the intelligent tester:

1. Connect the intelligent tester to the DLC3.
   

   Idle speed:

   720 to 820 rpm
   

   NOTICE:

   1. Turn all the electrical systems and the A/C off.
      
   2. When checking the idling speed, the shift lever should be in neutral.
      

   HINT:

   Refer to the intelligent tester operator's manual for further details.

When not using an intelligent tester:

1. Using SST, connect the tachometer test probe to terminal 9 (TAC) of the DLC3.

   NOTICE:

   1. Turn all the electrical systems and the A/C off.
      
   2. When checking the idling speed, the shift lever should be in neutral.
      
   3. Confirm the terminal number before connecting them. Connecting the wrong terminal can be damage the engine.
      

Start the engine.

Fully depress the accelerator pedal.

Check the maximum speed.
