Assembly intelligence
Know what the reference includes
Mating interface
Gasket seating, threads and head arrangement require their own exact evidence. The canister envelope cannot establish those interfaces.
Performance evidence
No micron threshold, beta ratio, bypass-valve setting or service interval is inferred from these dimensions or the item name.
Variants & relationship boundaries
No replacement, supersession or interchangeable part pair is accepted in this identity record. Similar dimensions and supplier cross-references cannot establish a reciprocal or transitive replacement.

Research identity is separate from installed fitment
- Accepted research scope
- Exact part identity profile
- Serial-specific installation
- Not established
- Before ordering
- Confirm the actual assembly, configuration, applicable manufacturer evidence and serial/build restrictions.
Model names, physical resemblance, dimensions and seller-reported associations cannot replace that evidence. No universal interchangeability is implied.
Identification workflow
Build a useful identification record
- Preserve Caterpillar and the full raw identifier 1R-1807, including its hyphen.
- Identify the actual engine/build and installed filter head or lubrication assembly.
- Use applicable manufacturer documentation to confirm the service element, interfaces and configuration restrictions.
- Keep seller inventory, condition, provenance and availability separate from the technical identity; confirm the application before ordering.
What these specifications mean
Diameter and length describe an outside envelope. They cannot establish thread, gasket, media performance or a machine installation. Converted metric values below are arithmetic references derived from the published inch values, not new measurements.

1R-1807: Engine oil filter
The manufacturer identifies this as an engine lubrication filter. Dimensions are identification context; matching dimensions do not establish an equivalent filter or machine application.

Values retain the manufacturer’s original published units and item scope. They do not prove interchangeability. The raw identifier, including its hyphen and leading characters, is preserved.
Confirm before ordering
- Check the current manufacturer catalogue against the machine and installed engine or assembly.
- Confirm applicable serial, regional and configuration restrictions with an authorized source.
- No machine application is established by this record. Check any documented service-package conditions separately.
