Mahle Starter Motor Solenoid 24V 300A MX39

Mahle Starter Motor Solenoid MX39 is a new solenoid switch for rotating electrical applications, rated at 24V and 300A. It is listed as a medium duty solenoid and uses magnetic activation, which are the key identifiers to check when matching it to a starter motor setup.

The body measures 112mm in length and 61mm in diameter, with 55mm mount centres and 6.5mm mount holes. Those dimensions matter when you are checking physical clearance, bracket spacing, and the mounting pattern against the original unit or replacement assembly.

This part is listed under starter motor spare parts and is marked for Mahle unit applications. It carries OEM number 11250187, part number MX39, and comes as a new item supplied each, with a one year warranty.

For anyone replacing a starter motor solenoid, the important checks are voltage, current rating, mounting dimensions, and the exact part or OEM number. This unit is a 24V solenoid rated at 300A, so it should only be considered where those electrical and physical details align.

Application and Buying Notes

Before ordering, compare the part number MX39 and OEM number 11250187 with the original solenoid or service paperwork. Those identifiers are the most reliable starting point for a replacement like this, especially when the unit is a 24V starter motor solenoid rated at 300A.

Physical fit is just as important as electrical match. Check the 112mm body length, 61mm body diameter, 55mm mount centres, and 6.5mm mounting holes against the existing assembly so the solenoid will sit correctly in the available space and on the existing mounting points.

The 300A rating is a useful guide to the duty level of the part, but it should not be used on its own as a fitment decision. The solenoid is described as medium duty and magnetic activation, so the application needs to suit both the electrical specification and the control design.

If the existing unit is badly worn or missing, compare the starter motor make, the mounting pattern, the electrical system voltage, and any stamped numbers on the old solenoid. For a starter motor spare part like this, confirming the exact application details before purchase is the safest way to avoid delays or returns.

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 MX39 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 Solenoid 24V 300A. Part number MX39 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 MX39, 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 solenoid switch 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.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

Compatibility note: Please confirm compatibility by matching part number MX39, OEM number 11250187, 24V voltage, 300A rating, and the listed mounting dimensions against the vehicle or starter motor application before ordering.
