- Cat wheel loaders 924F/G/H, 928F/G, 930G, 938F/G/H, 950G/G II/H, 962G
- Cat track-type tractors and integrated tool carriers using 1G-8878
- Cat skid steer loaders, telehandlers, and small excavators with the matching circuit
- Cat hydraulic excavators 320B L, 325B L, 345C in service positions specifying 1G-8878
Verify the filter callout in your machine’s parts manual or operator’s manual before ordering. Cat uses 1G-8878 in both hydraulic and transmission positions on different models — confirm by part number, not application name.
