Engine Service

Refer to the Maintenance Interval chart (page99) for change intervals. Refer to the Replacement Parts chart (page58) for filter part numbers.

Refer to the Engine Operator’s Manual for detailed engine information.

Checking Engine Mounting Hardware

All bolts that secure the engine mounting brackets to the engine and the loader frame should be checked and re-torqued as necessary. Refer to the Torque Specifications Chart (page109) for torque information.

Warning

Allow hot engine and hydraulic system components to cool before servicing.

Checking Engine Oil Level

Open engine cover (page60), pull out the dipstick and check the oil level. Markings on the dipstick represent FULL and LOW (add oil) levels.

Changing Engine Oil and Filter

Note: For new units, the initial oil change should be after the first 50 hours. Important: Always dispose of waste lubricating oil according to local regulations or take to a recycling center for disposal; do not pour onto the ground or down the drain.

The engine oil filter is located on the left side of the engine. Access the filter by removing the left rear access panel (two rubber latches), (Figure43).

Access for draining the engine oil is located on the belly plate of the chassis inside the left rear tire (Figure44).

To add new oil, open the engine access cover. Remove the oil fill cap and add the recommended type and quantity of oil. Refer to the Lubrication chart, page63. Visually inspect the remote oil drain hose for damage or leaks.

Changing Fuel Filter

The fuel filter is located on the right side of the engine. Unlatch the right engine access panel to access the filter and clean dirt from around the filter head. Remove the filter from the engine. Replace with a new filter element. Lubricate the seal on the new filter element with fuel before installing. Pump the hand primer on the water separator to fill the element, if it was not filled prior to installation. Start the engine and check for leaks. See page69 for location on the engine.

Checking the Water Separator

The water separator is located between the fuel tank and main fuel filter and is used to remove finely dispersed water in diesel fuel. Check on a daily basis and drain if necessary. If excess water collects in the separator an alarm will be shown on the information center electronic display. Water can be drained from the separator by opening the valve located at the bottom of the separator bowl.

Note: A water-in-fuel sensor leading from the bottom of the separator may need to be unplugged to open the valve.

After draining the separator, prime the fuel system with a hand pump located on top of the separator (Figure45).

Engine Diagnostic Chart

When detecting faults, the information center electronic display (page28) uses a diagnostic trouble code (DTC) screen to alert the operator to the occurrence of the fault conditions.

The following pages list descriptions, diagnostic trouble codes and fault codes for the engine.
