Mahle Starter Motor 24V 11T CW New Part No. MS77

The Mahle Starter Motor 24V 11T CW is a new rotating electrical unit with part number MS77. It is specified as a 24 volt starter motor with 11 teeth, clockwise rotation, and a 9.0kW power rating, making the key identification points clear when matching against the existing starter.

This unit is listed with a 3 hole starter mount, 3 mounting bores, 126mm mount centres A, B and C, and a 92mm flange diameter. It also notes an insulated return and a transmission type with reduction gear, so the mounting style and electrical setup should be checked carefully before ordering.

The overall length is 373mm, the pinion diameter is 56mm, the pinion at rest is 48mm, and the flywheel depth is listed at 51.0. Those dimensions matter when confirming clearance, engagement position and physical interchange, especially on equipment where starter space is limited.

A one year warranty is stated for this new Mahle starter motor. The fitment information provided includes HITACHI EH750-3 and TEREX O&K models such as TA35, TA350, TA40 and TA400, so application checking should be done against the exact machine model and build year where applicable.

Application and Buying Notes

Before ordering, match the part number MS77, the 24V electrical system, and the 11 tooth clockwise configuration to the starter already fitted to the machine. The 3 hole mount, 126mm mount centres and 92mm flange diameter are important checkpoints because a starter can look similar yet still be wrong at the mounting face.

The listed 9.0kW power rating and 56mm pinion diameter should be compared with the original unit rather than assumed from the vehicle brand alone. The pinion at rest measurement of 48mm and the flywheel depth of 51.0 are the sort of dimensions that affect engagement position and clearance, so they are worth confirming when replacing a starter in service.

Where fitment is not already known, use the machine model, year and existing starter details together. The supplied application references point to HITACHI EH750-3 and several TEREX O&K models, but the correct match still depends on the exact machine specification, as starter variants can differ within the same family.

This is a new Mahle unit and the warranty is one year, which gives a clear buying reference for customers wanting a direct starter replacement. Even so, the safest approach is to confirm the existing part number, mounting pattern and rotation direction before fitting, particularly on equipment with reduction gear starters.

If you are replacing a failed starter, compare the old unit’s dimensions, tooth count and mounting style with this listing rather than relying on appearance alone. The overall length of 373mm and the flange diameter of 92mm are practical identifiers that help avoid an incorrect order when working from partial information.

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 MS77 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.

Mahle Starter Motor 24V 11Th CW. Part number MS77 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 MS77, 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 HITACHI EH750-3, HITACHI EH750-3 2008, TEREX O&K TA35, TEREX O&K TA35 1998, TEREX O&K TA35 1999, TEREX O&K TA35 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.

Compatibility note: Confirm compatibility using part number MS77, the 24V specification, 11 tooth clockwise rotation, and the listed mounting and dimension details before purchase.
