What We Do

Diesel Repair On Site or In the Shop, Your Call

When a diesel truck or piece of equipment goes down, you have two options here. If it can't move, Matt loads up his tools and comes to you: farm, job site, wherever it is. If you can get it to him, bring it to the shop in Marshville and he'll work on it there with the full shop setup around him. Either way, you're talking to the same guy and getting the same quality of work.

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.

The shop in Marshville is a real working facility, not just storage for the service truck. If you bring your vehicle or equipment in, Matt has everything he needs on hand: proper lifts, welding equipment, machining capability, and the space to work on something without rushing. For repairs that need more than what fits on a service truck, the shop is where the job gets done right.

Services Included

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.

Shop-Based Repairs

Some repairs are better done in the shop: full engine rebuilds, precision machining, or work that needs a lift and proper tooling. Bring your truck or equipment to the Marshville shop and Matt handles it there with everything on hand.

How It Works

Simple Process, No Hassle

Getting your diesel equipment fixed with 704 Diesel is pretty straightforward.

Call and Describe the Symptoms

Give Matt a call at (704) 291-0286 and walk him through what the equipment is doing. The more detail the better: noises, smoke, fault codes, when it started.

We Come Out and Diagnose

Matt schedules a time and comes to your location. He runs a proper diagnosis on the equipment before discussing any repair options with you.

You Get a Straight Quote

Once the diagnosis is done, you get a clear quote for the work. No pressure, no surprises. If parts need ordering, Matt will let you know the timeline upfront.

We Do the Repair

Matt gets the work done on site whenever possible. If the job calls for more, such as welding, machining, fabrication, or a full rebuild, you can bring the equipment into the Marshville shop and he handles everything under one roof. No third parties, no runaround.

FAQ

Diesel Mechanic Questions

Some of the things people ask before they call.

What types of diesel vehicles and equipment do you work on?

Matt works on diesel pickup trucks, semi trucks, construction equipment, agricultural equipment, and various other diesel-powered machines. If it runs on diesel and something is wrong with it, give him a call and he can let you know if it is something he handles.

Can you come to my farm or job site?

Yes, that is kind of the whole point. Matt is a mobile mechanic, so he loads up his tools and drives to you. Whether you are on a farm in Union County or a job site in Mecklenburg County, he comes to where the equipment is.

Do you do diesel diagnostics?

Absolutely. Matt runs a proper diagnosis before any repair work starts. He wants to know exactly what is wrong before recommending parts or repairs. That approach saves you from paying for things that were not actually the problem.

What if I need parts ordered?

If the repair requires parts that are not already on the truck, Matt will let you know right away. He will give you a timeline on parts and get the repair scheduled as soon as they arrive. He is upfront about lead times so you can plan around it.

Do you do preventive maintenance on diesel equipment?

Yes. Oil changes, filter swaps, fluid inspections, belt checks. Matt can come out and handle regular maintenance on your diesel equipment. Keeping up with maintenance tends to prevent the expensive breakdowns, so it is worth scheduling.

Do you also do welding on the equipment during the same visit?

In many cases, yes. Since Matt runs a full shop in Marshville and does both diesel mechanic and welding work, if a repair needs a weld or fabricated part, he can handle it during the same visit or in the shop if it's more involved. You can also bring the whole machine to the shop if that's easier - welding, machining, and fab work are all done in-house. No sending you somewhere else.
