2. Remove the check/fill plug and fill the differential
with oil as specified in the Lubrication chapter.
When the oil flows out the oil check/fill hole,
replace the plug. Wait 10 to 15 minutes and repeat
this process until the axle is full. Repeat the pro-
cedure with the other axle (see illustration).
Axle Planetary Hubs
The axle hubs have one plug each used for draining
and filling (see illustration).
1. Position the wheel until the drain/fill plug points
down. This will allow the oil to drain out.
Remove the drain/fill plug.
IMPORTANT: DO NOT discharge oil onto ground.
Catch and dispose of per local waste disposal
regulations.
2. Re-position the hub so the drain/fill plug is hori-
zontal. Fill with fresh oil as specified in the
Lubrication chapter. Re-install the drain/fill plug.
Repeat this procedure on the other hubs.
CHECKING ALTERNATOR AND
FAN BELT CONDITION
Refer to the engine manual for proper belt tension
adjustment and replacement procedures. If the belt is
worn or cut, it should be replaced. Order replacement
belts from your Gehl dealer.
CHECKING EXHAUST SYSTEM
Examine the muffler and tail pipe for possible holes.
Re-tighten any loose clamps and make sure the mani-
fold outlet gasket is not leaking.
NOTE: Perform all other service requirements up
to this point as well as the following:
CHECKING HYDRAULIC SYSTEM
RELIEF PRESSURES
Pressure settings for relief valves
are pre-set at the factory. A test port
is provided at the hydraulic pump.
Before conducting any pressure
checks, check the engine speed.
Engine speed must be 950 to 1000
rpm at low idle, and 2690 to 2750
rpm at high idle.
Steering Relief Pressure
Plug a 3000 psi (207 bar) oil or liquid-filled gauge in
the main/steering test port. Turn the steering full to the
right or left. The gauge should read 2500 psi (172 bar).
Checking Main Relief Pressure
With the gauge in the main/steering test port and the
boom extended, retract the boom fully. The gauge
should read 3000 psi (207 bar).
CHANGING HYDRAULIC RESERVOIR
OIL AND STRAINER
Clean all dirt and debris from around the area where
the hydraulic system suction (large) hose connects to
the wall of the reservoir.
1. Remove the drain plug and drain oil. Wash or
blow off any collected particles on the magnetic
drain plug.
IMPORTANT: DO NOT discharge oil onto ground.
Catch and dispose of per local waste disposal
regulations.
