Maintenance, repair and care
Citan BAG0014.4
Brake shaft bearing, outer and inner
Caution! Ensure that no grease or oil will get into the brake. Depend-
ing on the design the cam bearing is not sealed at the brake side.
Only use lithium saponified grease with a drop point above 190° C.
Automatic slack adjuster ECO-Master
Whenever the brake lining is replaced:
1. Remove rubber seal cap.
2. Grease (80g) until fresh grease escapes from the setting screw.
3. Use the ring spanner to turn back the setting screw by approx.
one turn. Manually actuate the brake lever repeatedly.
4. Ensure a smooth automatic re-adjustment. If necessary, repeat
for several times.
5. Apply seal cap again. Grease once more.
Exchanging grease of the wheel hub bearings
1. Safely jack up the vehicle and release the brake.
2. Remove wheels and rod caps.
3. Remove the split pin and unscrew the axle nut.
4. Use a suited gear puller to remove the wheel hub with brake
drum, the taper roller bearings and the seals from the stub axle.
5. Mark the removed wheel hubs and bearing cages to ensure that
they are not mixed up then fitted again.
6. Clean the brake, check for wear, ensure that it is in ordinary
condition and check for function, replace worn parts.
Keep the interior of the brake free from grease and dirt.
7. Carefully clean the wheel hubs inside and outside. Completely
remove the old grease. Carefully clean bearings and seals (die-
sel oil) and check for reusability.
Before mounting the bearings slightly grease the bearing seating
and assemble all parts in the opposite order. Carefully drive the
parts on the force fits without tilting and damage by using tube
bushings.
Prior to fitting apply grease to the bearings, the wheel hub hollow
space between the bearings and the dust cap. The grease
should fill approx. one quarter to one third of the space in the fit-
ted hub.
8. Fit the axle nut and carry out the setting of bearings and brake.
Finally carry out a function check and a test travel and remedy
possibly noted faults.
