(1) Bottom mounts (Rubber mounts of body bottom plate) 1. Insert a spacer 43 mm thick (dimension marked with a) in the body end.

2. Measure distance b between the center of the body mount and the frame top (8 places on both sides).

3. Insert (b1 - 35), (b2 - 35), (b3 - 35) and (b4 - 35) pieces of shims (561-74-61531) in the points of b1, b2, b3 and b4 respectively. Omit the figures after the decimal fractions.

4. Install the bottom mounts and remove the spacers.

5. Lower the body and check that all of the 8 bottom mounts are in contact with the frame top. If not, adjust the shims.

6. Finish adjustment of the bottom mounts. * Before installing the frame temporarily, remove the paint from the grounding surface.

(2) Front mounts (Rubber mounts of body front plate) 1. After the above adjustment of the bottom mounts, place and tack-weld brackets 561-468A890 and 561-46-8A870 on the frame so that the clearance between the body and bracket will be 57 mm. (See Fig. 1) 2. Raise the body and weld the brackets permanently.

3. Insert 7 shims 561-74-61540 7 mm in total and install rubber pad 561-74-61521.

4. Lower the body and check that the total thickness of the rubber pad is 50 mm. If it is not 50 mm, set it to 50 mm by adjusting the shim.

5. Finish adjustment of the front mounts.

2. After the body is assembled, the discrepancy between the protector and cab must be 59 Âą 30 mm.

If the discrepancy is not 59 Âą 30 mm, adjust the shim of hinge pin (561-7461740) (See A-A).

Loosen the air bleeder valves of the right and left front suspensions to bleed all air.

(Check that air does not come out any more (only oil flows out), and then tighten the valves again. (Tightening torque: 39.2 – 49 Nm {4 – 5 kgm})) Check that the valves are closed and install the suspension gas filler unit to the suspension cylinders.

Connect the hoses of the suspension gas filler unit to the nitrogen gas filler valves. (Since there are 2 hoses, connect them to the right and left suspension cylinders so that pressure will be applied to both cylinders evenly.)

Open the valve of the suspension gas filler unit gradually.

When the suspension cylinders rise to the specified level shown above, close the valve.

(Supply the gas to the front side according to the decal and to the rear side so that the dimensions in the figure will be obtained.)

Remove the hoses from the nitrogen gas filler valves and move the chassis forward and in reverse to fit the suspension cylinders, and then stop without applying the brake. (Finally, stop the truck without applying the brake to prevent an uneven load caused by braking.)

Apply the parking brake and check the length of the suspension cylinders.

If the length of the suspension cylinders is out of the standard range, repeat steps 3 – 7. (Usually, adjustment is completed by repeating those steps 3 – 4 times.)

Precautions

1. Bleed air from the cylinders.

Quantity of oil to be supplied = 16.5 l (Reference) 2. Fill both suspension cylinders simultaneously.

3. Do not extract the suspension cylinders to the stroke end.

4. After moving the truck forward and in reverse, stop it without applying the brake.

5. Do not steer the truck before finishing this adjustment. (If it is steered, the piping may be broken.)
