- Track-Type Tractor:
- D3G (S/N: CFC1-UP; CFF1-UP)
- D4G (S/N: FDC1-UP; CFN1-UP)
- D5G (S/N: FDH1-UP; FDW1-UP)
Description of Change: A new assembly procedure will prevent the bolts that are securing the hydraulic oil filter base to the mounting bracket from loosening. The new procedure utilizes a thread lock compound. Also, the torque for the bolt (1) has been increased.
Adaptable To: The 154-9731 Thread Lock Compound is now used on bolt (1). The new torque for bolt (1) is 35 ± 5 N·m (26 ± 4 lb ft). The new assembly procedure is effective with serial numbers that are listed in Table 1.
| Model | Serial Number Effectivity |
| D3G | (S/N: CFC381-UP; CFF368-UP) |
| D4G | (S/N: CFN424-UP; FDC303-UP) |
| D5G | (S/N: FDH885-UP; FDW504-UP) |
Note: The hydraulic oil filter base may become loose on machines that are not listed in the effectivity above. Machines that were built prior to the machines that are listed above can be reworked with the following procedure. The new procedure is adaptable to all machines.
Rework Procedure
- Remove bolts (1) that are securing the hydraulic oil filter base to the mounting bracket.
