3.3.1 Instructions for replacing the sleeve bearing of K55A, K55C, SK55A en SK55C
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 rack shaft by loosening the entire rack section . First loosen the two lock nuts M12
on the top of the rack section and then loosen the two bolts M12x60 . Loosen the six bolts M12x30 on the
side of the rack section a few turns to take the pressure off the rack shaft.
5. Support the rotating cylinder so that it no longer rests on the fork carrier gear wheel.
(Use appropriate lifting equipment; the minimum lifting capacity must exceed the weight of the box rotator;
see technical data - chapter 2.1)
6. Turn the nuts M12 and the adjusting bolts M12x40 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 plug
. Remove the
tapered roller bearings
of the shaft plug from the
bearing house of the fork carrier . Clean the bearing housing and the shaft plug, 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 plug. Clean the lubrication duct, if necessary.
9. Push the new tapered roller bearings around the shaft plug and in the bearing house, as shown in figure
3.3.1.
10. Return the
fork carrier
to the
back plate
. Avoid any damage to the
tapered roller 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 and firmly secure the locking plate, using the bolts M12x50 . (100 Nm)
12. Fasten the adjusting bolts M12x40 of the roller bearings in the locking plate by hand and then turn back a
quarter of a stroke. Secure the adjusting bolts M12x40 , using the lock nuts M12 .
13. Fasten the two
bolts M12x60
on top of the
rack section
(60Nm) until the
rack shaft
slips back into the
gear
wheel . Secure the rack section by tightening the six bolts M12x30 on the side of the rack section.
14. Put the box rotator back onto the forklift truck/mast and return the forks.
15. Lubricate the bearings, connect the hydraulic hoses, and check that the box rotator is working correctly.
