Caterpillar Belt-Driven Water Pump Assembly Casting 107-7701 No Hole - Used, Untested

Caterpillar belt-driven water (coolant) pump assembly, removed as a take-out. Two-groove V-belt pulley, cast inlet and outlet elbows, flanged bolt-on mounting plate, CAT logo cast into the housing. Casting numbers 107-7701 "NO HOLE" and 4W-0253 "W/HOLE" are cast into the housing — these are foundry casting identifiers, not confirmed orderable CAT service part numbers, and no data plate or stamped service number is present.

Application: not verified. The donor engine model and arrangement are unknown, so no engine fitment is claimed.

Condition: used, untested take-out (Grade C). Paint intact with surface rust on the elbows, pulley and mounting plate. Shaft rotation, bearing play, seal condition, pressure and flow have not been tested. Drained and capped before shipment.

Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
