The 3054 Engine in the 914G Wheel Loader and IT14G Integrated Tool Carrier may experience hot restart difficulty or lack of power caused by the fuel lines entering and exiting the fuel filter head assembly. These fuel lines are being changed to eliminate these occurrences. In addition, the wiring harness that crosses the engine bellhousing may be routed incorrectly causing the harness to be cut.

Illustration 2Harness Routing
The 1145344 and 1083261 Harnesses go under the 1164812 Sheet Metal Guard. The 1145344 Harness emerges about 150mm from under the sheet metal guard and crosses the bellhousing at the rear. The vibrations of the engine could cause this harness to be cut by the sheet metal and therefore needs to be routed differently.
The two harnesses are tied together as they cross the bellhousing. When they reach the sheet metal guarding over the Hystat Pump, the thicker 1145344 Harness should cross to go behind the engine (to the starter motor and alternator) before going under the sheet metal. The thinner 1083261 Harness should go under the sheet metal and down the back of the bellhousing to the Hystat Pump.
