Pipelayer:
572RSeries II (S/N: DSC1-UP)
Track-Type Tractor:
D7R (S/N: 9HM1-UP; 2EN1-UP; 3DN1-UP; 2HR1-UP)
D7RSeries II (S/N: AEC1-UP; AFG1-UP; ABJ1-UP; AGN1-UP; ACS1-UP; ADW1-UP)
D8R (S/N: 7XM1-UP; 9EM1-UP)
D8RSeries II (S/N: AKA1-UP; 6YZ1-UP)
D8T (S/N: J8B1-UP; KPZ1-UP)

Description of Change: A new cover plate for the bottom guard is now used. The new cover has two improvements. The first improvement is the addition of a stiffener plate that will lessen the possibility of debris from puncturing through the cover into the engine oil pan. The second improvement is a change from a cover with two bolts for mounting to a cover with one bolt and a tab for mounting. This improvement will prevent the bottom bolt from getting sheared when the machine is used in adverse conditions.

Adaptable To: The new 318-0640 Cover Assembly can be installed on existing bottom guards as a direct replacement for 107-6174 Cover Assembly. A new washer and a new bolt are also required. For bottom guards that have metric threads, the new part numbers will be 8T-4136 Bolt and 8T-4222 Plated Washer. For bottom guards that have standard threads, the new part numbers will be 4L-6454 Bolt and 2D-6414 Washer .

If a new middle bottom guard is ordered, a new 318-0640 Cover Assembly will be ordered automatically, as the old 107-6174 Cover Assembly is not adaptable to the new middle bottom guard assemblies.

This improvement is effective with the following machines:

  • 572RSeries II (S/N: DSC533-UP)

  • D7RSeries II (S/N: ABJ1715-UP; AGN1933-UP; AEC2246-UP)

  • D8R9EM5521-UP

  • D8T (S/N: KPZ3576-UP; J8B2206-UP)

This improvement is adaptable to the following machines:

  • 572RSeries II (S/N: DSC1-532)

  • D7R (S/N: 3DN1-UP; 2EN1-UP; 9HM1-UP; 2HR1-UP)

  • D7RSeries II (S/N: ABJ1-1714; AGN1-1932; AEC1-2245; AFG1-UP; ADW1-UP; ACS1-UP)

  • D8R (S/N: 9EM1-5520; 7XM1-UP)

  • D8T (S/N: KPZ1-3575; J8B1-2205)
