8.3.3. Replacing the hydraulic fine filter at rear axle steering
The hydraulic system of the rear axle steering is equipped with a hydraulic fine filter.
The fine filter is situated in the left-hand engine cowling, next to the coarse filter behind the electrical
cabinet (see Picture 8-5 ).
For replacing the hydraulic fine filter, the following steps must be carried out:
1. Turn off the diesel engine of the truck;
2. Place an oil tray under the filter;
3. Unscrew the bottom of the filter (wrench width 19);
4. Remove the filter from the holder;
5. Clean the holder, if necessary, with a lint-free dry cloth;
6. Replace the O-ring by a new one, which is lightly greased (see § 14.4. Specifications
hydraulic system truck );
7. Replace the fine filter by a new one (see § 14.4. Specifications hydraulic system truck );
8. Mount the bottom of the fine filter.
If there are problems with the rear axle steering, the hydraulic fine filter should be checked.
For more information, see § 5.3.6. Maintenance schedule hydraulic system truck.
INFORMATION!
Replace this fine filter once per 5 years when the coarse filter is removed,
related to limited working space.
