D8N/R/T GENERAL DUTY
UNDERCARRIAGE INTRODUCTION
AVSpare
introduces Cat? General Duty Undercarriage. AVSpare created
the new line for Cat machines operating in lower usage or lighter duty
applications where the full value of Positive Pin Retention Undercarriage is
not realized. General Duty Undercarriage is
AVSpare designed and
available exclusively through Cat dealers. Additional machine models will
follow this offering in the future.
Key Features of
General Duty Undercarriage

-
In some circumstances, a turn can be completed with lower post-turn life expectations compared to PPR
-
-
Requires minimum maintenance using standard inspections
-
Checking for loose or broken hardware, leaks, dry joints, shoe overlap, etc.
-
-
CTS Wear Charts will be available
-
Service major groups
-
Track Groups & Link Assemblies
-
Idler Groups
-
Roller Groups
-
Sprocket Segments
-
-
General Duty groups and assemblies can be repaired with Heavy Duty components
-
