1.
Disconnect the hydraulic hoses.
2.
Remove the forks from the forklift truck.
3.
Take the box rotator from the forklift truck / tractor and put it on its back on a flat, stable surface.
4.
Take the pressure off the
guide block
by loosening the pressure
bolts M16x60
.
5.
Support the rotating cylinder so it will no longer rest on the gear wheel of the
fork carrier foldaway
model/fork carrier plug-in model
(use appropriate lifting equipment; the minimum lifting capacity must
exceed the weight of the box rotator; see technical data in chapter 2.1)
6.
Remove the
locking plate
after unscrewing the
socket bolts M12x30
. Prevent the fork carrier of the back
plate from unexpected movements.
7.
Pull the fork carrier from the shaft of the fork positioner, clean the shaft of the fork positioner of the
back
plate
and check for wear and tear.
Contact the dealer after detecting any wear. Also check the lubrication.
The lubricant must be applied to the bearing bush via the grease nipple and the opening on the shaft of the
fork positioner. Clean the lubrication duct, if necessary.
8.
Push the old
sleeve bearing
out of the bearing housing from the gear wheel side to the front of the fork
carrier. Clean the bearing housing and the shaft of the fork positioner.
9.
Push the new
sleeve bearing
into the bearing housing. Make sure the
sleeve bearing
fits well and avoid any
damage. The front of the sleeve bearing must be flush with the front of the bearing housing.
10.
Return the
fork carrier
with the new
sleeve bearing
onto the
back plate
. Avoid any damage to the
sleeve
bearing
by means of good support and guidance. Make sure the
fork carrier
and the
rotating cylinder
are
correctly repositioned.
11.
Mount the
locking plate
with three
bolts M12x30
and secure firmly (100Nm).
12.
Return the
guide block
and put it under pressure by using the
pressure bolts M16x60
(60Nm). Secure the
bolts using the
lock nuts M16
.
13.
Put the box rotator back onto the forklift truck/tractor and return the forks.
14.
Lubricate the bearings, connect the hydraulic hoses, and check that the box rotator is working correctly.
Always use original WIFO parts for replacement in order to comply with the warranty terms and conditions.
