OEX Starter Motor 12V 9 Tooth CW Hitachi Style HXS093

The OEX Starter Motor HXS093 is a 12V, clockwise rotating starter motor in a Hitachi style, set up with 9 teeth and a 2.0kW power rating. It is supplied new, uses a 2 hole starter mount, and has a 120mm mount centre measurement, which are the main checkpoints when comparing it to an existing unit.

This starter is listed with a 95mm flange diameter, 13mm mount hole diameter, 214mm overall length, and a 35mm pinion diameter. The pinion at rest measures 22mm, and the unit weighs 4.66kg, so it is important to compare the physical dimensions against the removed starter before ordering.

The stated application note is for Yanmar 2 tier engine use in Thermo King applications, with a flange to rear measurement of 190. Verified fitment references also include a range of Thermo King models and series, so part number HXS093 and the mounting measurements should be checked carefully against the vehicle or equipment in question.

Application and Buying Notes

When comparing this starter to the original unit, the most important checks are the 12V electrical system, clockwise rotation, 9 tooth pinion, and the 2 hole mounting pattern with 120mm mount centres. The 95mm flange diameter, 13mm mount hole diameter, 214mm overall length, and 35mm pinion diameter are also useful physical checks before purchase.

The application note specifically mentions Yanmar 2 tier engine use in Thermo King applications, with a flange to rear measurement of 190. That measurement should be matched against the existing starter or the engine arrangement, because starter motors can differ by mounting depth and housing dimensions even when they look similar.

The listed Thermo King model references cover several SB, SL, Spectrum, Super II, and TK4.86V (Tier 2) applications. Even with those references, the safest approach is to confirm the part number HXS093, the Hitachi style housing, and all mounting dimensions against the removed unit, especially where the equipment has been serviced or converted previously.

This unit is supplied new and carries a 3 year passenger / 1 year commercial warranty, but warranty coverage does not replace fitment confirmation. If the original starter is available, compare the old unit’s teeth count, rotation, mounting style, and overall length directly before fitting this replacement.

At 4.66kg, this is a substantial rotating electrical component, so correct support during installation is important. Take care with cable routing, terminal position, and mounting alignment so the starter seats properly and engages the ring gear as intended.

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 HXS093 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 HXS093 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 HXS093, 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 THERMO KING SB-II, THERMO KING SB-II 1980, THERMO KING SB-II 1984, THERMO KING SB-II 1992. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility by matching part number HXS093, 12V clockwise rotation, 9 tooth count, 2 hole mounting, and the supplied dimensions against the original starter and equipment application before ordering.
