Follow steps 1 to 3 in chapter on ‘Instructions for
Replacement of Sleeve’.
Replacement of Hydraulic Parts
Loosen the hose connectors (3) slightly so that the pistons
do not create a vacuum when removing the hydraulic
parts.
Tools required
: Open-ended spanner size 19.
Place a drip tray below the fork. Unscrew the cylinder
head(s) (5) using a cylinder head spanner (4) and a
ratchet.
Tools required
: Cylinder head spanner, 1/2’’ ratchet.
*Cylinder head spanners are only available from Meijer
Handling Solutions B.V. (Art. Nº RE0058049).
Pull the entire hydraulics set (6) consisting of the piston,
cylinder head and piston rod out of the fork.
Caution:
Take care with the surface of the piston rod.
Minor damage to surface can cause leaks.
Clamp the piston rod at the rod end (7), not on the piston
rod itself to prevent damage (see step 4 in this chapter).
Use a size 19 (8) open-ended spanner to loosen the piston
(9). If the piston cannot be loosened, heat the piston with
a burner.
Tools required
: Open-ended spanner size 19, clamp.
Note:
When heating the piston with a burner, it must be re-
placed due to the damage to the seals caused by heating.
Warning:
Do not use a burner in an area not equipped/in-
tended for his purpose because of fire hazard.
Warning:
Do not carry out maintenance work on the
KOOI-REACHFORKS® whilst there is pressure
in the hydraulic system (remove key from forklift
ignition switch).
