Clean Spark Arrestor Muffler
(Non-Turbo Units only)
IMPORTANT: Non-Turbo powered loaders are
factory-equipped with a USDA Forestry Service
approved spark arrestor muffler. Muffler
maintenance is required to keep it in working
condition. Refer to local laws and regulations for
spark arrestor requirements.
To clean the muffler, open the rear grille and engine
access cover. Loosen the front muffler clamp and
remove the rear clamp and muffler. Dump the contents
of the spark chamber and reinstall the muffler. Check
that the muffler clamps are secure and, after starting the
engine, that the exhaust system is quiet and NOT
leaking.
Check Alternator/Fan Belt Tension and
Condition
Refer to the Adjustments chapter and the separate engine
manual for setting proper belt tension. If the belt is worn,
cracked or otherwise deteriorated, replace the belt
following the procedure in the separate engine manual.
Tighten Wheel Nuts, Check Drive Chain
Tensions and Check Oil In Chaincases
Torque the wheel nuts to 170-180 ft-lbs (244 N·m).
Check drive chain tension following the procedure
under the “Drive Chains” topic in the Adjustments
chapter of this manual.
Each SL46/4835 drive chaincase requires 8 U.S. quarts
(7,6 liters) of SAE motor oil. Fill until oil runs out of the
oil level check plug. This quantity of oil should be
maintained at all times.
Check Hydraulic Filter Indicator (Fig. 10-2)
WARNING
Before servicing the hydraulic filter, BE SURE
the lift arm is lowered.
When checking the filter indicator, STAY
CLEAR of the rotating cooler fan blades. If you
come in contact with the fan blades, serious
injury will result.
To check the hydraulic filter element, run the engine at
full throttle and normal operating temperature. Lift the
engine access cover. Observe the hydraulic filter
indicator located on the filter head. If the indicator is
green, the filter does not need replacing. If the indicator
is red, replace the filter following the instructions
below.
1. Turn OFF the engine.
2. Open the reservoir drain plug located in front of the
right rear tire.
3. Drain the oil out to a level below the point where the
filter attaches to the reservoir.
4. Replace the reservoir drain plug.
5. Refill the hydraulic oil reservoir with oil. Refer to
the Lubrication chapter for hydraulic reservoir oil
recommendations.
6. Spin off the old hydraulic filter element and spin on
the new filter element.
For replacement spin-on hydraulic filter element, refer
to the “Replacement Parts” topic at the beginning of this
chapter.
