Application and Buying Notes

Before ordering, confirm the 24V electrical system, the 10 tooth pinion count, and the clockwise rotation, as these are core identifiers for this BXS9052 starter motor. The listed Bosch style and suits Bosch unit make detail are important, but matching the physical dimensions is just as critical for fitment.

Check the mounting pattern against the 3 hole starter mount, 127mm mount centres A, 90mm mount centres B and C, and the 11mm mount hole diameter. The 89mm flange diameter, 315mm overall length, and 40mm pinion diameter should also be compared with the removed unit or the application requirements.

The unit is rated at 4kW, so it is best matched by specification rather than appearance alone. A starter that looks similar can still differ in rotation, tooth count, flange size, or pinion depth, and those details matter when the application is being matched for a Caterpillar machine or another Bosch-style setup.

If you are replacing a starter on a commercial machine, weigh the 8.6kg unit carefully against the existing part and verify the dry clutch application. The warranty is stated as 3 years passenger and 1 year commercial, so it is worth confirming how the vehicle or machine is used 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 BXS9052 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.

For part number BXS9052, 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 120M, CATERPILLAR 120M 2008, CATERPILLAR 3054, CATERPILLAR 3054 2002. 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 matching part number BXS9052, the 24V specification, 10 tooth CW configuration, and the mounting dimensions against the removed starter or application listing before ordering.
