Car and classic
Starter and dynamo commutators for cars and classics
For modern cars a new commutator is a rebuild option; for classics it is often the only one. Lucas dynamos and inertia starters, Bosch dynastarters and pre-war units all use commutators that have not been made for decades. We make them to the original dimensions.
What we see with car and classic starters
- Classic British, European and American cars and motorcycles
- Lucas C39/C40 dynamos, M35 and M418 starters, Bosch dynastarters
- Made to measure is the normal route for classics; the A to E diagram shows what to measure
