Semi trucks and Class 8 tractors

Cylinder head, block and component machining for the engines in over-the-road tractors and vocational trucks.

The work

Semi trucks and Class 8 tractors

A truck that is not moving is not earning, which is why most over-the-road work arrives with a deadline attached. PDM takes heads, blocks and rotating assemblies from Class 8 tractors and vocational trucks, and works with fleets and independent truck shops across western Ohio and central Indiana.

Delivery and pickup run on established routes, so a component can move without tying up one of your people for a day.

Manufacturer names are used to describe the engines PDM machines and rebuilds. PDM is an independent machine shop and is not affiliated with, endorsed by, or an authorised dealer for any manufacturer named on this page.
