Compatibility toolPart fitment and serial number checker
Check a part number against a machine model and, when the cited manufacturer or technical source publishes a structured serial range, test the entered serial number against that documented rule.
Part + modelrequired to test a stored fitment relationship

Source-backedresults only; missing data is never converted into a fitment claim
Verified model fitment found
Verified model fitment found. No structured serial-number restriction is recorded for this fitment.
The model relationship is documented. Add a serial number when available; some applications depend on serial break, market or configuration.
ConfigurationCurrent North America WORKMASTER 55/65/75 utility tractor; Tier 4B catalog family from 09/18 onward
Fitment note30-micron spin-on fuel filter listed for the current WORKMASTER 55, 65 and 75 utility model family (09/18-present). Depending on the fuel-system arrangement this filter may serve as a pre-engine or water-separator stage; verify configuration before orderi

Verified rangeFits verified serial range
The stored source explicitly supports the model and the entered serial falls inside its documented range.
Model-level evidenceSerial unverified
The model fitment is documented, but a machine-specific serial rule is unavailable or cannot be tested from the current source.
No assertionNo verified direct fitment
This means the catalog lacks a direct cited relationship for the query. It does not mean the part is definitely incompatible.
This tool only confirms rules already stored from cited sources. A missing fitment or missing serial rule is not proof that a part is incompatible. Always verify the complete machine PIN, model year, market and configuration before ordering. See
Data Sources & Methodology for the publication rules used by this site.
