INJECTION-PUMP ASSEMBLY
Information:
Introduction
Correction to D3G failures of the fuel injection pumpProblem
The D3G has had failures of the fuel injection pump. The failures are seen as low power, running rough, smoking, and hard starting. The failures occur from 8 to 1350 hours. Most failures have been concentrated in the 8 to 400 hour range. There appears to be no environmental aspects or application aspects to the failures at this time. Solution
The rotary fuel pump that is used on the Track-Type Tractors uses diesel fuel for lubrication of the pump. One plunger is used for all 6 injectors. This increases the sensitivity to fuel quality. Customers that are having problems should use 256-4968 Fuel Conditioner . This should help fuel quality by increasing the lubrication. This additive can also be used with low sulfur diesel. Use this fuel conditioner according to directions. For more information, refer to , PELJ0525, "Introducing New Cat Diesel Fuel Conditioner". Low sulfur diesel is already available in many states per the 2007 Highway Diesel Rule. Refer to the following map that shows the areas that produce lower sulfur diesel fuel.

Note: Toyu fuel is not suitable for use in these machines. Toyu fuel does not provide any lubrication for the pump. Using this fuel may cause early failures.
