Fitment and Service Notes
The 1R-0719 is one of the most widely used hydraulic/transmission return-line cartridges in the Caterpillar range, which is exactly why it matters to get the cross-reference right. It is a cartridge-style element — not a spin-on can — and it is fitted in the return-line circuit, where it catches wear debris before oil goes back to the tank. Common fitments include the D9N/D9R/D10N track-type tractors, the 120H/140G/140H motor grader family, the 966/980 wheel loader series and the 777/785/789 mining truck range. The same element also appears on compactors, scrapers, articulated trucks and underground LHD loaders.
Before ordering, read the part number stamped on your old element. 1R-0719 (written 1R0719 on some labels) is the number to match; equivalent aftermarket numbers include Baldwin PT189, Fleetguard HF6097 and HF35539, Fram CH155PL, Donaldson P559740/HFP559740/P164200/P165024 and AC Delco PF295/PF87. We supply high-quality aftermarket elements cross-referenced to the OEM number, typically 40–60% below genuine Cat pricing, and we confirm fitment against your machine serial before anything ships.
