- Track-Type Tractor:
- D11N (S/N: 4HK1-UP; 74Z1-UP)
- D11R (S/N: AAF1-UP; 8ZR1-UP; 9TR1-UP; 9XR1-UP; 7PZ1-UP)
Description of Change: Several improvements have been made to the D11R and D11R CD implement pump and hose configuration.
The new gear pump is a more rugged design in order to improve overall quality of the pump. Also, these improvements will decrease the possibility of leaks within the pump.
Note: The main suction hose from the hydraulic tank to the implement pump has also been changed. This new suction hose must be used with a new pump.
Adaptable To: The new 227-9383 Gear Pump (implement pump) replaces the former 6E-5294 Gear Pump (implement pump). This new 227-9383 Gear Pump (implement pump) requires the use of the new suction hose.
The new 228-4838 Gear Pump (implement pump) replaces the former 157-4761 Gear Pump (implement pump). This new 228-4838 Gear Pump (implement pump) requires the use of the new suction hose.
The new 221-0293 Hose As (suction hose) replaces the former 9U-8509 Hose As .
The new implement pumps and suction hose are effective with the following machines in 1.
