Diesel Repair & Welding
Mobile or In-Shop

Matt Harris runs both a mobile unit and a fully equipped shop in Marshville. We come to your job site when that's the easier call - and customers drop off vehicles, parts, and equipment at the shop when the work calls for it. Either way, 704 Diesel & Welding has it covered across the Carolinas.

What We Do

Everything You Need, One Call Away

We cover a wide range of diesel mechanic and welding work - from showing up to your job site with the mobile unit to having customers bring in vehicles, parts, and equipment for shop repairs, precision work, and custom fabrication. If it runs on diesel, needs a weld, or needs to be built from scratch, we can handle it.

Diesel Mechanic Services

Engine diagnostics, repairs, and maintenance for diesel trucks, heavy equipment, and commercial vehicles. We come to you or you can bring it to the shop - whichever works best.

Mobile Welding

Matt brings the welding equipment straight to your location. Broken frames, cracked buckets, snapped attachments - we come to you so you don't have to haul it.

Learn More

Heavy Equipment Repair

Excavators, bulldozers, backhoes, loaders - if your heavy iron is down, we come to the job site or you can trailer it in to the shop. Either way, we get it diagnosed and back in service fast so your crew stays productive.

Learn More

Industrial Welding

Structural welds, heavy-duty repairs, and industrial component restoration done on site or in the shop. We weld to hold - not just to patch.

Learn More

Line Boring Services

Save yourself from buying expensive new parts. Line boring restores worn bores to factory tolerances at a fraction of replacement cost. We perform this work in-shop for the best precision, or on-site when bringing equipment in isn't practical.

Learn More

Metal Fabrication

Custom brackets, guards, mounts, structural steel components, and one-off builds - all done in the shop. If you can sketch it out or describe what you need, we can probably make it. Material sourcing, cutting, fitting, and welding all handled in-house.

Learn More

Custom Steel Fabrication

Need something built from scratch? Bring in your sketch, a broken original part, or just a description of what you need. We source the material, cut it, fit it, and weld it together in the shop.

Learn More

Structural Welding & Fabrication

Frames, beams, support assemblies, and load-bearing metalwork built and welded in-shop. Work that requires a controlled environment and solid fit-up is exactly what this shop is set up for.

Learn More

In-Shop Services

Drop off your vehicle, equipment, or parts at the Marshville shop for repairs and work that's better handled in a controlled environment. Diesel repairs, line boring, welding, and fabrication all under one roof.

Emergency equipment repair on job site

Emergency Equipment Repair

Equipment breakdowns don't wait for business hours. When something goes down unexpectedly, call Matt - we do our best to get to you as fast as possible. Downtime costs real money and we get that, so we make it a priority to respond fast.

Both options work. Matt runs a fully mobile setup and will come to your job site, farm, or property. If it's something better handled in the shop - like fabrication work, complex repairs, or precision jobs - or you can trailer it in, that works too. The shop is equipped for welding, cutting, fitting, and building. Just give him a call and you'll figure out the best plan.
The everyday service area is roughly 50 miles from Marshville, NC - that covers most of the Charlotte area, Union County, Mecklenburg, Cabarrus, Stanly, and into Lancaster and Chesterfield County in South Carolina. For bigger jobs, Matt has traveled further. Just ask.
Diesel trucks, excavators, backhoes, loaders, bulldozers, skid steers, and most types of construction and agricultural equipment. If it has a diesel engine or needs welding work, there's a good chance Matt can handle it.
Yes - Matt does his best to respond quickly to urgent equipment breakdowns. Call him directly at (704) 291-0286. Regular business hours are Monday through Friday, 7AM to 5PM, but reach out and he'll do what he can to help.
Line boring restores worn or damaged bore holes in equipment back to their original tolerances. If your machine has excess play in a pin joint, you're hearing knocking, or a repair shop told you a major component needs replacing - line boring is often a much cheaper fix that brings things back to spec. Matt can handle this on site.
