Description of Change: The sensor-dials resistive elements in the fuel level senders have been improved internally to prevent intermittent or open conditions.Adaptable To: The 138-0444, 139-8661, 139-8662, 139-8663, 139-8665, and 139-8666 Sensor-Dials in the Fuel Level Sender Assembly have been improved effective with date code D97 (D = April, 97 = 1997) at the supplier. The improvement can also noted be noted by checking the part number marked on the top of the complete sender assembly. The change level of the new sender has been marked after the part number, while senders made before the improvement DO NOT have the change level marked after the part number. The part numbers of the improved Sensor-Dials and the part numbers of the associated former Sensor-Dials are shown in Chart 1. The location of the sensor-dial is shown in Illustration 1. To check effectivity for the machine being serviced, and to find the correct Fuel Level Sender Assembly part number and improved Sensor-Dial part number, refer to Chart 2. This is a partial list of effective serial numbers because not all effective serial numbers are known at this time. As a reference, the sensor-dial will read approximately 95 ohms at the full position and 2 ohms at the empty position when using the Caterpillar 6V-7070 Multimeter or equivalent. Typically, the sensor-dial is all that needs to be replaced on a malfunctioning sender assembly.
