Mobile Diesel Mechanic

Diesel Mechanic Services

Matt comes to your location - farm, job site, or shop. No tow trucks, no waiting rooms, just solid diesel work done right where you need it.

Real Diesel Repair, Right Where You Are

When a diesel truck or piece of equipment goes down, the last thing you want to deal with is finding a tow, hauling it to a shop, and waiting days to get a look at it. Matt Harris started 704 Diesel and Welding Services in 2022 to fix that problem. He loads up his tools and comes to you - whether that's your farm in Union County, a construction site in Mecklenburg, or your shop in Lancaster County SC.

Matt has hands-on experience working on diesel trucks, heavy equipment, and agricultural machinery. He has dealt with everything from a fuel system that won't cooperate to an engine that just gave up on a Monday morning. He runs proper diagnostics before he starts quoting you on parts, so there are no guesses and no surprises on the bill.

One of the bigger advantages of working with Matt is that he also does welding and fabrication. If the repair turns out to need a weld or a fabricated bracket, he can handle it in the same visit instead of sending you to another guy. That saves time and keeps your equipment moving.

Diesel Mechanic Work We Cover

From diagnostics to full repairs, here is what Matt handles on diesel engines and equipment.

Diesel Engine Diagnostics

Matt runs thorough diagnostics before any work starts. Knowing what is actually wrong saves you money and keeps the repair on target.

Engine Repair and Rebuild

From top-end work to full rebuilds, Matt handles diesel engine repairs on trucks, construction equipment, and agricultural machines.

Fuel System Service

Injectors, fuel pumps, filters, and lines. A diesel running rough or losing power often traces back to the fuel system, and Matt can sort it out on site.

Cooling System Repair

Overheating is a fast way to turn a small problem into a big one. Matt handles radiator repairs, coolant flushes, water pumps, and thermostat replacements.

Electrical and Starting System

Dead batteries, bad alternators, starter issues, and wiring faults. Matt diagnoses and repairs electrical problems that keep your equipment from starting or running right.

Preventive Maintenance

Oil changes, filter replacements, belt inspections, fluid top-offs, and general checkups. Keeping up with maintenance is cheaper than emergency repairs.
