Application and Buying Notes

Before buying, compare the 24V rating, 11-tooth count, clockwise rotation, and 2-hole mount layout against the unit being replaced. The listed dimensions of 104mm mount centres, 77mm flange diameter, 11mm mount hole diameter, and 241mm overall length are the best practical checks when the original starter is available for comparison.

The starter is described as Mitsubishi style and the fitment list provided includes Caterpillar applications. That means the right choice should be confirmed by the part number MXS9619, the OEM number 185-9157, and the exact machine application, rather than by general appearance alone.

If the old unit is missing or unreadable, check the electrical system voltage, pinion tooth count, pinion diameter of 34mm, and the 9.5mm pinion at rest measurement before ordering. These details matter because starter motors with similar housings can still differ in rotation, tooth count, and mounting dimensions.

This part is supplied new and carries a one-year warranty. The OEX brand note states that products are sourced from original equipment manufacturers and aftermarket suppliers, and from ISO certified factories, which is useful background when comparing replacement options, but it does not replace the need to verify the exact fitment data for your application.

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 MXS9619 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 Mitsubishi Style. Part number MXS9619 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 MXS9619, 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 CATERPILLAR 307C, CATERPILLAR 307C 2001, CATERPILLAR 307C 2002, CATERPILLAR 307C 2003. 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 using OEX part number MXS9619, OEM number 185-9157, the 24V specification, 11-tooth count, clockwise rotation, and the listed mounting dimensions before purchase.
