Tilt Cylinder Leak Check

STEP 6.

Install a new wiper seal in the retainer. Turn the re-
tainer into the cylinder shell until the threads have
started. Push the piston in and out several times to
make sure the alignment is correct.

Tilt Cylinder Leak Check

WARNING

Never allow anyone under a raised carriage.
Do not put any part of your body in or through
the lift mechanism unless all parts of the mast
are completely lowered and the engine is
STOPPED.

Do not try to find hydraulic leaks by putting
your hand on hydraulic components under
pressure.

Hydraulic oil can be injected into

the body by the pressure.

1.

Put a capacity load on the forks. Use a safety
chain to hold the load to the carriage. Raise the
load approximately 2.5 m (8 ft). Put the mast in
a vertical position.

2.

Measure the distance that the rod for tilt cylin-
der extends from the shell. Check the distance
the rod moves in five or ten minutes. Multiply
the rate in Table 1 by the time of the test and
compare the numbers.

3.

If the tilt rate is greater than the specifications,
lower the mast and remove the load from the
forks. Install a valve between the port at the
front of the tilt cylinder and the hydraulic line.
Put the load on the forks again. Close the valve.
Tilt the mast forward just past the vertical posi-
tion. If the mast continues to tilt slowly forward,
the seals on the piston are leaking.
