§Equipment
Dump trucks and vocational trucks
Engine machining for dump trucks and the vocational fleets that run them.
The work
Dump trucks and vocational trucks
Vocational trucks accumulate hours rather than miles, and they are usually part of a small fleet where one truck down is a real proportion of capacity.
PDM works with municipal, construction and aggregate fleets on head and block machining and on complete rebuilds, with delivery and pickup on established routes.
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.
