OEX Starter Motor 12V 9 Tooth CW Hitachi Style HXS063

This OEX starter motor is a 12V unit with a clockwise (CW) rotation, 9 teeth on the pinion and a 1.0kW power rating. It is listed as a Hitachi style starter motor, new, with part number HXS063 and a 2-hole starter mount type.

Key dimensions include a 110mm mount centres A measurement, 70mm flange diameter, 11mm mount hole diameter and 207mm overall length. The pinion at rest measures 17mm, the pinion diameter is 29mm and the unit weighs 3.24kg.

This starter motor is identified for Yanmar applications in the supplied fitment data, including Yanmar 1GM, 1GM10, 1GM10C, 1GM10V, 2GM, 2GM20C, 2GM20F, 2GM20FV, 3GM, 3GM30C, 3GM30F and 3GM30FV variants. Because starter fitment depends on mounting and drive details as well as model name, the part number and dimensions should be checked carefully before ordering.

Application and Buying Notes

Before ordering, match the part number HXS063, the 12V electrical requirement and the clockwise (CW) rotation to the original unit on the vessel or machine. Starter motors can look similar while differing in tooth count, flange size, mount centres and pinion position, so the 9-tooth drive, 110mm mount centres and 70mm flange diameter are important checks.

The listed Yanmar applications cover several 1GM, 2GM and 3GM variants, including C, F and FV suffix models. Even within the same engine family, the starter can differ by mounting pattern or drive configuration, so confirm the existing starter against the 2-hole mount type, 11mm mount hole diameter and 207mm overall length rather than relying on model name alone.

If you are replacing a Hitachi-style starter, the make and style reference can help narrow the search, but the physical dimensions remain the safest guide. The 29mm pinion diameter, 17mm pinion at rest measurement and 1.0kW rating should line up with the replacement requirement before fitment is attempted.

The warranty listed for this unit is 3 years for passenger use and 1 year for commercial use. That does not replace fitment checking, so compare the old starter and any service information with the supplied measurements before fitting the new part.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number HXS063 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

OEX Starter Motor 12V 9Th CW Hitachi Style. Part number HXS063 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number HXS063, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a starter motor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include YANMAR 1GM, YANMAR 1GM 1980, YANMAR 1GM10, YANMAR 1GM10 1980. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm compatibility using part number HXS063, the 12V CW configuration, the 9-tooth pinion, and the mounting measurements before purchase. Fitment should always be checked against the existing starter and application details for the engine or equipment.
