Improved Wiring Groups are Used {1403, 1408}
- Off-Highway Truck/Tractor:
- 793D (S/N: FDB1-UP)
- Wheel Loader:
- 994F (S/N: 4421-UP)
Description of Change: The wiring groups in the engine arrangements in the above machines have been changed. Improved pressure sensors have been added. Changes have been made to the lengths of the breakouts in the wire harness in order to accommodate the new leads for the sensors.
Adaptable To: Table 1 lists the former parts and new parts. The new sensors may be used with the previous harness by gathering and tie-wrapping the excess lead.
This change is effective with the engine's serial number (S/N: 8WM01731-UP).
