Visually check the belt for cracks, oiliness or wear. Check that the belt does not touch the bottom of the pulley groove.

If necessary, replace the belt.

Check the vane pump V belt deflection by pressing on the belt at the point indicated in the illustration with 98 N (10 kgf, 22 lbf) of force.

• Standard Deflection:

• Item	Specified Condition
  New belt	8 to 10 mm (0.314 to 0.393 in.)
  Used belt	10 to 15 mm (0.393 to 0.590 in.)

Using a mirror, check that the matchmarks of the injection pump flange and timing belt case are aligned.

Loosen the following nuts and bolts.

Align the matchmark by slightly tilting the injection pump.

Tighten the following nuts and bolts.

Warm up the engine.

When using the intelligent tester:

When not using an intelligent tester:

Start the engine.

Fully depress the accelerator pedal.

Check the maximum speed.

• Maximum engine speed:
• 4850 to 4950 rpm

Warm up and stop the engine.

Remove the glow plugs.

Disconnect the spill control valve connector.

Check the cylinder compression pressure.

Install SST (attachment) to the glow plug hole.

• SST
• 09992-00026(09992-00121)

• Момент затяжки:
• 13 N*m{ 133 kgf*cm, 10 ft.*lbf}

Connect SST (compression gauge) to SST (attachment).

• SST
• 09992-00026(09992-00121,09992-00211)

Fully open the throttle valve, and start the engine.

While cranking the engine, measure the compression pressure.

• ПРИМЕЧАНИЕ:

• This measurement must be done as quickly as possible.

• УКАЗАНИЕ:

• Always use a fully charged battery to obtain an engine speed of 250 rpm or more.

Repeat the steps above for each cylinder.

• Standard compression pressure:
• 3138 kPa (32.0 kgf/cm², 455 psi) or higher

• Minimum pressure:
• 1961 kPa (20.0 kgf/cm², 284 psi)

• Difference between each cylinder:
• 490 kPa (5.0 kgf/cm², 71 psi) or less

If the cylinder compression in one or more cylinders is low, pour a small amount of engine oil into the cylinder through the glow plug hole and check the compression pressure for the cylinder with low compression.

• УКАЗАНИЕ:

Remove SST.

Reinstall the glow plugs.

Reconnect the spill control valve connector.
