Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products. Dispose of all fluids according to local regulations and mandates. |
Note: Three filters are associated with the auger hydraulic system. You should replace all three filters at the same time.

- Park the machine on level ground. Engage the parking brake.
- Lower the bowl to the ground. Shut off the engine.
- Clean hydraulic oil filler cap (2). The hydraulic oil filler cap is located on top of the hydraulic tank.
- The hydraulic oil filler cap is a locking cap. If a padlock is on the cap, remove the padlock. Raise lever (1) in order to engage the lug.
- Turn the hydraulic oil filler cap counterclockwise in order to remove the cap. Slowly remove the cap in order to relieve pressure in the hydraulic tank. Replace the cap after you have relieved pressure in the hydraulic tank.
- Clean the area around the filters.
- Remove the filters with a strap type wrench. Refer to Operation and Maintenance Manual, "Oil Filter - Inspect" for further information. Discard the used filters properly.
- Clean the filter mounting bases. Make sure that all of the old filter seals are removed.
- Apply a thin coat of clean hydraulic oil to the seals on the new filters.
- Install the new filters hand tight until the seal of the filters contacts the filter mounting bases. Note the position of the index marks on the filters in relation to a fixed point on the filter mounting bases.
Note: There are rotation index marks on each filter that are spaced 90 degrees or 1/4 of a turn away from each other. When you tighten the filters, use the rotation index marks as a guide.
- Tighten the filters according to the instructions that are printed on the filters. Use the index marks as a guide. For non-Caterpillar filters, use the instructions that are provided with the filters.
Note: You may need to use a Caterpillar strap wrench, or another suitable tool, in order to turn the filters to the amount that is required for final installation. Make sure that the installation tool does not damage the filters.
- Start the engine. Check for leaks at the filters.
- Check the hydraulic oil level. Add oil to the hydraulic tank, if necessary. Refer to Operation and Maintenance Manual, "Hydraulic System Oil Level - Check" for more information.
