Instructions for replacing the tapered roller bearings of K54A-Z/K54C-Z/SK5A-Z/SK54C-Z
1.
Disconnect the hydraulic hoses.
2.
Remove the forks of 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.
Turn the
adjusting bolts M10x35
of the bearings in the
locking plate
back one full stroke.
7.
Remove the
locking plate
after unscrewing the
bolts M12x50
. Prevent the fork carrier of the back plate from
unexpected movements.
8.
Pull the fork carrier from the shaft
of the
screwable fork positioner
. Remove the
tapered roller bearings
from the shaft of the fork positioner and from the bearing housing of the fork carrier. Clean the bearing
housing and the shaft of the fork positioner, 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.
9.
Push the new bearings around the shaft of the fork positioner and into the bearing housing, as shown in
figure 3.3.1.
10.
Return the
fork carrier
with the new
tapered roller bearings
onto the
back
plate
. Avoid any damage to the
bearings by means of good support and guidance. Make sure the
fork carrier
and the
rotating cylinder
are
repositioned correctly in relation to the back plate.
11.
Mount the locking plate using the bolts M12x50 and secure firmly (100 Nm)
12.
Fasten the
adjusting bolts M10x35
of the
bearings
in the locking plate by hand and then turn back a quarter
of a stroke. Secure the adjusting bolts M10x35 using the lock nuts M10.
13.
Fasten the adjusting bolts of the
adjusting strip
by hand and then turn back half a stroke.
14.
Return the
guide block
and put it under pressure by using the
pressure bolts M16x60
(60Nm). Secure the
bolts using the
lock nuts M16
.
15.
Put the box rotator back onto the forklift truck/tractor and return the forks.
16.
Lubricate the bearings, connect the hydraulic hoses, and check that the box rotator is working correctly.
