Mahle Starter Motor 12V 10T CW MS999

The MAHLE starter motor listed here is a 12V unit with 10 teeth, clockwise rotation, and a reduction gear transmission type. It carries part number MS999 and is described as an OE product, which makes those identifiers the first points to check when matching it to a vehicle or machine.

This starter motor has 3 mounting bores, a mounting points diameter of 146, a bore O 1 of 13.2, and a tooth pitch of 14.1. The flywheel depth listed is 35, so those dimensions should be compared carefully with the existing starter and the application requirements before ordering.

It is supplied as a single unit, with a net weight of 6000 and packaging dimensions of 39.0 length, 18.80 height, and 21.50 width. The warranty is one year, and the product group is rotating electrical, which is useful context when checking replacement expectations and installation planning.

Application and Buying Notes

Before ordering, confirm the part number MS999 and check that the existing starter is a 12V, 10-tooth, clockwise unit. Those three details are the most practical first checks because starter motors are commonly distinguished by voltage, pinion tooth count, and rotation direction.

Fitment references are provided for BELARUS SERIES 100 applications, including several year listings. Even with those references, it is still sensible to confirm the exact application against the machine’s current starter, because production changes and previous repairs can alter what is fitted.

Because this is an OE product in the rotating electrical group, it is best handled as a direct replacement candidate rather than a universal part. Use the supplied measurements, the 12V rating, and the MS999 part number together when confirming suitability with your parts record or removed sample.

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 MS999 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.

Additional published details for cross-checking include Product Group 2 STARTER MOTORS, Part No. MS999, Brand MAHLE, Description Mahle Starter Motor 12V 10Th CW, Number of Teeth 10, Voltage 12, Bore O 1 13.2, Tooth Pitch 14.1, Mounting points diameter 146, Packaging width 21.50.

Mahle Starter Motor 12V 10Th CW. Part number MS999 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 MS999, 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 BELARUS SERIES 100, BELARUS SERIES 100 1992, BELARUS SERIES 100 1998, BELARUS SERIES 100 2000. 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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Always confirm compatibility using part number MS999, the 12V 10-tooth clockwise specification, and the listed mounting and flywheel details before purchase. If anything on the existing starter differs, do not assume it will interchange.
