Hitachi S13-204 12V Starter Motor 129900-77010 - Used, Untested

Hitachi 12-volt starter motor, data plate marked 129900-77010 / S13-204 / 786, MADE IN JAPAN. Cylindrical field frame with cast aluminum drive-end housing, integral solenoid, and what appears to be a 9-tooth pinion drive (buyer should hand-count to confirm).

Application: not verified. The plate number 129900-77010 follows a Japanese-diesel OEM numbering format and this Hitachi S13-series unit is the type fitted to small Japanese industrial and marine diesel engines, but no donor engine plate or catalogue confirmation is in hand. Sold by photographs, identifiers, and dimensions — buyer must cross-reference the number against their own engine model and serial number.

Condition: used, untested take-out. Complete in appearance with solenoid attached. Paint is heavily chipped with scattered surface corrosion and rust on the pinion. It has NOT been bench tested, no-load tested, or cranked, and we make no claim that it operates. A bench test is recommended before installation.

Quote is subject to final fitment confirmation by engine/transmission serial number, part number, photos, and supplier availability.

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.
