6.7 Hydraulic Oil – Changing
CAUTION!
Risk of burns to exposed skin.
Hydraulic oil becomes hot during
operation. Hoses, lines, and other
parts become hot as well. Wait for
the oil and components to cool
before starting any maintenance or
inspection work.
W028
Change the hydraulic oil at 100 hours of operation or
annually. Change the return filter and clean the suction
strainer in the hydraulic tank at the same time.
• Hydraulic oil type: Dexron III ATF.
• Reservoir capacity is 7 US gal (30 L).
The hydraulic tank may occasionally need to be drained. The
drain plug is located at the bottom of the hydraulic tank. Follow
this procedure to drain the tank:
1. Have a drain pan ready of suitable capacity.
2. Clean the area around drain and remove the drain plug.
3. Allow the oil to fully drain, then flush the tank. Dispose of
used oil in a environmentally acceptable fashion.
4. Install the drain plug.
5. Clean the filter suction strainer before filling the tank.
Dispose of used oil in an environmentally acceptable fashion.
IMPORTANT! Be aware of high oil temperatures. Optimum
temperatures are 120–140 °F (50–60 °C). Temperatures
higher than 180 °F (82 °C) could cause seal damage and
degrade the hydraulic oil. High oil temperatures are often a
symptom of another problem.
6.7.1 Clean Suction Strainer
With the hydraulic tank emptied, the suction strainer should be
removed and cleaned. The strainer is made of stainless steel
screen and is reused.
The suction strainer is located on the back of the tank, between
the fuel tank and the battery box.
1. Remove the suction hose, then remove the strainer.
2. Place the suction strainer in a solvent tank and use a small
brush to clean it. Examine the strainer screen and replace it
if there are holes or damage.
3. Dry the suction screen thoroughly, then re-install.
6.8 Hydraulic Oil Filter
With the hydraulic tank emptied, the hydraulic return filter should
be changed.
For optimum performance, the filter element should be
changed every 100 hours.
The filter is located on top of the
hydraulic oil tank.
1. Have a drain pan ready to catch any dripping oil.
2. Remove the three screws on the filter cover and pull the
cover off.
3. Remove the filter element and clean the bottom of the bowl.
4. Check that the O-rings are not damaged. If they are, replace
them.
5. Install the new filter element.
6. Reinstall the filter cover and tighten the screws to 44 lbf•in
(5 N•m) .
7. Fill the tank with clean oil. The proper oil level is when it is
visible in half the glass window.
