Roadwork signEmergency Road Service – Truck Repair

We weld and fabricate on the spot and do all our own computer and electrical diagnostics. We are here for you 24/7, weekends and holidays.

We weld mild steel, stainless and aluminum, and we carry a large stock of metal to fabricate any structural solution for frames, boxes, ramps lifts, etc…

AIR BRAKES

Air brakes are a big thing in our field.

At Mobile Diesel Medic we see so many problems with broken air lines, faulty relay vales, and defective brake pods that we carry the entire set of air brake hardware and air brake lines on all four of our service trucks. Lots of weekend headaches have been solved via this strategy.

HYDRAULICS

We carry tone generators to quickly locate electrical shorts in wiring harnesses; all four of our service trucks carry batteries and possess the capacity to fabricate our own battery cables in the field. Starting and charging issues are every day common place for our team.

RV & BUS REPAIR

Gasoline or diesel? We repair all types and sizes of motor homes and busses. This line of service has by far been the most interesting. We have repaired water leaks under sofas, AC circuit breaker issues, and even axles on vehicles that have been dragged off the Golden Gate Bridge. Call and inquire. We will repair it or we don’t charge.

BOATS

We know what it’s like to pull a 400 pound cylinder head out of the engine room of a commercial fishing boat. Our team has dealt with many “reverse ship in a battle” engine rebuilds. We repair all the water in fuel issues as well as the big engine and hydraulic jobs.

HEAVY DUTY EQUIPMENT – CONSTRUCTION & FARM

Cranes / Dozers / Excavators etc…

Repinning back hoes, tightening tracks on excavators, balancing the swash plate on a crane, rebuilding turn decks….This is our bread and butter work. If your equipment needs welding, servicing, or some complicated hydraulic diagnostics, Mobile Diesel Medic possesses the experience and equipment to diagnose and repair you toughest equipment headaches.

OIL EVACUATION

No more oil pans!!

All service trucks come equipped with pneumatic lube and oil evacuation systems.

During an oil service your used motor oil is vacuumed out directly from your motor to our service trucks. Fleet accounts are equipped with special oil drain plugs that attach to our evacuation systems.

For our first or one time customers we do still carry oil pans.

BRAKES

Just because we’re mobile doesn’t mean we don’t do brakes. We’ll lift your equipment up in the air, and you don’t even need to bring your equipment in to a shop to do it. We’ll come to you, wherever you are.
