Starters as cores

Starters, together with alternators, are among the largest reman product groups worldwide. They are standardised, robust and on the road in enormous numbers. For remanufacturers, the supply of type-sorted starter cores is the basis of production.

Why this part is valuable as a core

Housing, armature, field frame and gearing are usually reusable. Carbon brushes, bearings, solenoid and one-way clutch are replaced.

The variety of variants is large: number of teeth, direction of rotation, flange and output must match exactly. That is why we identify every starter by OE or manufacturer number.

Do you also take 24 V starters from trucks?

Yes, commercial vehicle starters are in particular demand.
