Seal-kit fitment taken from Caterpillar's own Mini Excavator Parts Reference Guide — Genuine CAT Parts (newer edition, opened in full as a mirror of the Caterpillar-authored PDF — the same OEM-authorship basis as the Parker Hannifin and Phoenix Contact datasets in this catalogue). Every record is one row of the guide's "Cylinder Parts — Blade Lift / Blade Tilt" table: the machine model, its serial-number prefix, the cylinder application, the seal kit part number, and the cylinder tube and rod part numbers printed in the same cell. Covered models: 303E CR, 303.5E CR, 303.5E2 CR, 304E2 CR, 304.5E2 CR XTC, 305E2 CR, 305.5E2 CR (all sharing Blade Lift kit 469-0717 and Blade Tilt kit 469-0723) and 305.5E2 FB / 306E2 FB, which print separate rod and piston seal kits per cylinder (461-0668 / 461-0669 lift, 461-0859 / 461-0860 tilt).
Corroboration: the 2018 edition of the same guide (Mini Hydraulic Excavator — Parts Reference Guide, PEBJ0124-03, July 2018) prints the same Blade Lift / Blade Tilt kits for the same seven CR models — identical numbers, independently read in that edition's PDF.
Counting basis, stated plainly: one record per model × cylinder application (× rod/piston split where the guide prints one): 7 CR models × 2 applications + 2 FB models × 2 applications × 2 kits = 22 records, 6 distinct seal kit part numbers. The FB rows' bushing kits (461-0309, 461-0857) are printed in the same cells and noted in the file, not counted as seal-kit records.
Honesty notes: the same guide's main Cylinder Parts tables hold dozens more model→seal-kit mappings (Boom, Stick, Bucket, Boom Swing and blade cylinders for 300.9D–308E2 CR VAB), but the PDF text layer flattens those tables' two-row column headers, so the exact cylinder-application label per column cannot be certified from a text read — they are excluded from v1 rather than guessed. The Blade table used here has single-row, explicit headings. No dealer catalogue (SIS), no dealer-only seal book (PEKP1020) and no third-party seal-house table contributed any record. The guide publishes no serial ranges and no prices, so no record carries either.
Verification standard: one Caterpillar-authored guide, opened in full, with the record table read directly by the build run; every record confirmed character-for-character against the printed table, including serial prefixes and tube/rod numbers.
