4
Removal of the legs/leg pivots can be done, as follows.
5
Remove the mast and boom assembly and set aside. Turn the lift base upside down and unscrew the 24 off M6 CSK head
screws that secure the base plate to the cross member.
6
Remove the base plate.
7
To enable the leg pivot pin to be inspected, it will be necessary to remove the set pin that holds the piston end of the actuator
in place on the cross member. Once the pin is removed the leg and the actuator can be lifted free from the cross member.
8
Remove the leg and actuator taking care not to lose the bronze bearing washers at each end of the leg pivot pin.
NOTE:
Support the actuator to prevent damage to the mounting point still attached to the leg. If any work is to be done on the
leg, it is safer to remove the actuator.
9
The leg pivot pin can now be withdrawn and inspected.
10
Clean the pin of any debris or replace the pin if worn.
11
Inspect the leg pivot bush in the leg. Clean the bush in the leg of any debris or replace the leg if it is worn.
RE ASSEMBLY OF THE LEG PIVOT PINS
1
Lubricate the leg pivot pin with any light mineral-based grease, or silicon spray.
2
Place one of the bronze washers over the hole in the main base casting of the cross member.
3
Refit the pin into the leg with the deeper shoulder of the pin going into the main base casting of the cross member.
4
Place the leg over the pivot.
5
Place remaining bronze washer over the leg pivot pin so that it rests on the surface of the leg bush.
6
Replace the set pin
(after applying threadlock)
that secures the actuator piston to the centre of the cross member and
tighten to 5 Nm
.
7
Replace the plates.
8
Apply loctite to the M6 CSK screws and
tighten them to 5 Nm
.
9
Ensure the leg actuators open and close the legs correctly.
NOTE:
Before applying threadlock to any screw or bolt check it can be screwed into the component without hindrance from old
remaining threadlock. This could affect the proper torque setting.
CROSS MEMBER - LEG ACTUATORS
To remove the actuators you will need to remove the base plate and leg assemblies as per the procedure listed under
“Cross
member - legs / leg pivot pins”
(parts 4 to 7, page 13).
1
The set pins can now be removed from the leg end on the actuators.
2
Disconnect the bullet connectors on the wiring looms to remove the actuators from the hoist.
3
After inspection or replacement, reconnect the bullet connectors.
