Application and Buying Notes

Before ordering, match the part number HXS9403 and confirm the starter is the same 24V configuration as your original unit. Voltage, tooth count, rotation, and mount style all need to align, especially where the vehicle has been fitted with a similar-looking Hitachi style starter motor.

The physical dimensions are just as important as the electrical rating. Check the 3 hole mounting pattern, 131mm mount centres A, 115mm mount centres B and C, 105mm flange diameter, 395mm overall length, and 40mm pinion diameter against the removed starter. If any of these differ, the unit may not seat or engage correctly.

The 11 tooth pinion and clockwise rotation are important compatibility checkpoints for starter replacement work. Even where the application list appears close, starter motors can vary between model variants, engine setups, and production changes, so confirm the original unit details rather than relying on vehicle name alone.

This starter is listed as a new unit and is backed by a 3 year passenger and 1 year commercial warranty. The warranty period is useful for peace of mind, but the correct way to avoid a mismatch is still to verify the part number, voltage, rotation, tooth count, and mount measurements before purchase.

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 HXS9403 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 24V 11Th CW Hitachi Style. Part number HXS9403 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number HXS9403, 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 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include NISSAN UD NET6A, NISSAN UD NET6A 1988, TADANO GT-550E, TADANO GT-550E 2008, TCM 870, TCM 870 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.

Compatibility note: Please confirm fitment using part number HXS9403, the 24V CW specification, and the listed mounting and dimension details before ordering. Vehicle applications should always be checked against the removed starter and the specific application listing.
