The article referenced above contains a chart listing effectivity of new fuel level senders. Additional effectivities have been added to chart 2 for fuel level senders. The new 159-0647 Sensor Kit and 159-0240 indicator Assembly are used when replacing the former 139-8662 Sensor Kit. The new sensor kit change has been added to charts 1, 2, and 3. The article states that the fuel level sender resistance should be about 95 ohms at the "full" position and 2 ohms at the "empty". Actually, the resistance is 64 to 255 ohms at empty and 0 to 29 ohms at full (varies depending on P/N). An additional chart has been added to Service Magazine SEPD0453, Article 27, Page 17 giving the expected resistances for specific part numbers. See the Service Magazine SEPD0453, Article 27, Page 17 named "Fuel Level Senders Improved to Prevent Open Circuit Conditions" for the corrections and additions.

On Page 30, Chart 2 contains incorrect information. The row with the Sales Model Number 950F Series II has an incorrect serial number and sender part number. Under the Effective Serial Number column, 5SL2982 is incorrect. The correct serial number should be 5SK2982. Under the Sender Part Number coumn, part number 107-1846-02 is incorrect. The correct part number should be 107-1849-02.

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.
