Vehicle Systems Testing And Adjusting

Tilt cylinder pivot eyes can loosen if the torque on

the pivot eye clamping bolt is not tight enough. This

will let the tilt cylinder rod turn in the tilt cylinder eye.

The cylinder rod may then twist our of the pivot eye

and the tilt cylinder will be out of alignment or may

let the mast fall and cause personal injury or

damage. When the rod lengths are made even, the

tilt angle differences or the mast alignment will no

longer be a problem.

3. Tighten bolt (2) and the nut to a torque of 95 L 15

NIm (70 L 10 lbIft).

4. With mast at full back tilt, install shims (4) as

required to permit no gap between spacer (5) and

head (6). Shim so mast does not twist at full tilt

back.

Drift Test

Drift is movement of the mast or carriage that is the

result of hydraulic leakage in the cylinders or control

valve. Before testing the drift:

Personal injury can be caused by sudden move-

ment of the mast or carriage. Use wood blocks

and clamps to hold the mast in this position. Keep

hands and feet clear of any parts that can move.

1. Check the chain adjustment and tilt cylinder align-

ment and make necessary adjustments.

2. Lift the mast approximately 762 mm (30 in). Use

wood blocks and clamps to hold the mast in this

position.

3. Check the mast hinge bolts to make sure they are

tight.

4. Remove the blocks and clamps and lower the

mast.

Drift Test For Lift System

1. Put a rated capacity load on the forks of the lift

truck. Operate the lift truck through a complete lift

and tilt cycle until the oil is at normal temperature

of operation, 45 to 55ûC.

2. Put the mast in a vertical position.

Raise a rated capacity load to a sufficient height to

test the lift cylinders.

3. Measure any drift of the carriage for a ten minute

period. Drift for all models shall not exceed 100.0

mm (4.00 in).
