Application and Buying Notes

Before ordering, match the part number DXS9118 against the original starter and compare the physical dimensions: 105mm mount centres, 82mm flange diameter, 340mm overall length, and 12.5mm mount hole diameter. These measurements matter as much as the electrical rating because a starter can be 12V and still differ in mounting layout or engagement depth.

The 10 tooth pinion, 32mm pinion diameter, and 34mm pinion at rest are important checkpoints where the starter engages the engine. The unit is also listed as clockwise rotation and 28MT series, so the replacement should be checked against the old starter’s rotation and series style rather than relying on appearance alone.

This starter is listed for Delco units and dry clutch use. If the original part has a different rotation, tooth count, mount type, or clutch arrangement, stop and compare the specifications carefully before fitting. A close visual match is not enough when the mount centres, flange diameter, and pinion dimensions are known.

For commercial applications, the warranty is listed as 1 year, while passenger applications are listed as 3 years. Keep the invoice and confirm how the vehicle or equipment is used, since that warranty split is part of the product information supplied here.

If you are replacing a starter on equipment or machinery, the safest approach is to confirm the original unit’s part number, voltage, tooth count, rotation, and mounting dimensions together. Those details give a far more reliable match than model name alone, particularly where multiple Delco-style starters can be used across different applications.

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 DXS9118 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 10Th CW Delco 28MT Style. Part number DXS9118 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 DXS9118, 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 ATLAS COPCO XAS375, ATLAS COPCO XAS375 2010, BOBCAT 975, CHAMBERLAIN 3380, CHAMBERLAIN 3380B, CHAMBERLAIN 4090. 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 fitment by checking part number DXS9118, Delco application details, 12V rating, 10 tooth CW configuration, and the mounting and pinion measurements before purchase.
