A New Alternator Support and a New Belt are Used {1397, 1405}
- 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: A new alternator support is used that improves the alignment between the drive pulley and the alternator pulley. The new support helps prevent premature wear to the alternator belt. A new alternator belt with improved belt material is used.
Adaptable To: The 293-3324 Alternator Support and the 294-0110 Belt are adaptable to the D11 Track-Type Tractors that are listed above.
The 7E-6617 Alternator Support is cancelled and replaced by the 293-3324 Alternator Support. The 294-0110 Belt replaces the 100-3725 Serpentine Belt. The 100-3725 Serpentine Belt is still used in other applications.
Serial number effectivity is listed in Table 1.
