Application and Buying Notes

Before ordering, match the part number 438146, the 12V rating, the 10 tooth pinion, and the clockwise rotation to the starter you are removing. Those are the most useful identifiers for avoiding an incorrect replacement when the vehicle application is not being matched by VIN or catalogue reference.

The listed mounting details are also important. This starter uses a 2 hole mount, 8mm mount holes, and 99mm mount centre-to-centre spacing, so the mounting face and bolt pattern should be checked carefully against the vehicle and the removed unit.

Physical size can affect clearance around the bellhousing and adjacent components. The key dimensions listed here are 205mm overall length, 70mm flange diameter, 49mm nose cone length, and a 26mm pinion diameter, with the pinion at rest measured at 14mm.

This starter is described as a Valeo unit and is supplied new, with a one year warranty. If you are replacing an existing starter, comparing the old unit against these measurements and the part number is the safest way to confirm the correct match before fitting.

The product is listed with fitment references that include Mercedes-Benz A-Class applications, but the safest approach is still to confirm the exact vehicle application against the part number and the physical starter details above. A nominal match in make or model name is not enough if the mounting, tooth count, or rotation differs.

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 438146 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 438146, 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.

Compatibility note: Please confirm fitment by checking part number 438146, 12V, 10 tooth, clockwise rotation, 2 hole mount, and the listed dimensions against the vehicle and the removed starter before purchase.
