7.7 Hydraulic Oil Change

7.7-1
The hydraulic oil should be changed
every 1000 service hours. Before
beginning the procedure, make sure
the machine is in a clean working
environment. Take any necessary
measures to prevent dirt or debris from
entering the hydraulic system.
To change hydraulic oil and filter:
1. Shut the machine down according to the procedure in section 5.13.
2. Allow the machine to cool, then release any residual pressure in the
hydraulic system by following the procedure in section 4.7 of this manual.
3. Locate and remove the hydraulic fluid drain plug (item 1) through the drain
hole in the belly pan. (fig. 7.7-1)
4. Drain the used oil into a suitable catch container.
5. Dispose of the oil according to local mandates.
6. Reinstall the drain plug and tighten.
7. Refill the hydraulic reservoir (item 3) with Mobil DTE 10 Excel Series 46
Hydraulic Oil, or equivalent. (fig. 7.7-2)
Note: Observe the hydraulic oil level sight gauge (item 4) located on the back of
the hydraulic reservoir to ensure that the level is correct (fig. 7.7-3). Once oil is
visible, fill slowly to avoid overfilling.
8. Once full, start the engine according to the proper starting procedure and
operate all hydraulic circuits to work any trapped air out of the system.
Then, check the oil level. If low, add oil as necessary until full.
