OEX Starter Motor 12V 10T CW Delco 37MT Style DXS9135

The OEX starter motor DXS9135 is a 12V unit in 37MT style, configured for clockwise rotation and a 10 tooth pinion. It is listed as a new starter motor and suits Delco applications, with a 4.5kW power rating for heavy-duty rotating electrical use.

Key physical details include 127mm mount centres A, 90mm mount centres B and C, an 89mm flange diameter, 11mm mount hole diameter, and an overall length of 400mm. The pinion diameter is 40mm and the pinion at rest measurement is 48mm, so these dimensions should be checked carefully against the original unit before ordering.

This starter motor is supplied under the OEX brand, with a stated warranty of 3 years for passenger use and 1 year for commercial use. It is a 3 hole starter mount type and is listed as suitable for wet or dry clutch applications, which makes the part number and physical measurements especially important when matching it to the vehicle or machine.

Confirmed application guidance

• Do not rely on make alone; confirm the part number DXS9135 against the original starter and the machine application.
• Listed applications include Delco-based equipment across BELARUS, CASE, CATERPILLAR, CUMMINS, HITACHI, INTERNATIONAL, JOHN DEERE, MANITOU, MASSEY FERGUSON, NEW HOLLAND, ONAN, RIVIERA, TIMBERJACK, VERMEER, VERSATILE and WHITE.
• Examples shown in the application data include CUMMINS QSM11, CATERPILLAR 910 and 910F, HITACHI LX100, JOHN DEERE 310J and 310SJ, MANITOU 4RM35B and 4RM40K, NEW HOLLAND TX64, and MASSEY FERGUSON 364 and 399.
• The fitment data also references DELCO and 37MT style applications, so the starter body dimensions and mounting pattern should be matched before installation.
• Some application entries are broad family listings rather than a single exact model, so the original unit should be checked for tooth count, rotation, mount centres and flange size.

Application and Buying Notes

When comparing this starter motor to an existing unit, start with the part number DXS9135, then confirm the 12V rating, 10 tooth pinion and clockwise rotation. Those details matter because a starter can look similar while still having a different drive end, mounting pattern or pinion engagement.

The mounting dimensions are important on this unit: 127mm mount centres A, 90mm mount centres B and C, an 89mm flange diameter and 11mm mount holes. If your original starter differs in any of those measurements, the replacement may not line up correctly even if the vehicle make appears in the application list.

The 4.5kW power rating, 23.5kg weight and 400mm overall length also help distinguish this starter from lighter or shorter variants in the same general family. For older or mixed-equipment applications, it is wise to compare the original starter body, nose profile and cable position rather than relying on a broad model reference alone.

This unit is listed as suitable for wet or dry clutch applications, but that still does not replace a direct match on the starter itself. A careful check of the original Delco unit, the mount type and the pinion at rest measurement of 48mm will reduce the chance of a costly mismatch.

Warranty cover is listed as 3 years for passenger use and 1 year for commercial use. If the starter is going into commercial or heavy equipment service, it is sensible to verify the exact operating duty and installation details before fitting, because correct match-up is still the key factor in reliable operation.

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 DXS9135 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.

Compatibility note: Confirm fitment using part number DXS9135, the Delco application details, and the measured mount centres, flange diameter, rotation and pinion specifications before purchase. If the original starter does not match these details, do not assume interchangeability.
