What We Do

Restore Worn Bores Without Replacing the Whole Component

Heavy equipment takes a beating. Over time, the pin bores and bearing bores on excavators, dozers, loaders, and other machines wear out of spec. When that happens, you start seeing sloppy movement, increased play in the linkage, accelerated wear on pins and bushings, and eventually full component failure. It's a common problem, and it gets expensive fast.

Line boring is a precision machining process that restores those worn bores back to the correct tolerance - right where the equipment sits. Instead of pulling the machine apart and shipping a boom, stick, or frame section to a machine shop, Matt brings the equipment to his shop or comes out to your site and does the work on the spot. The bore gets cleaned up, machined back into round, and sized correctly so a fresh pin and bushing fits the way it's supposed to.

The results speak for themselves. Equipment that was showing serious slop and wear comes back tight, smooth, and working the way it should. And the cost is a fraction of what you'd spend buying a replacement boom, bucket cylinder, or frame assembly. If your machine still has good structural integrity, line boring is almost always the smarter call.

Common Line Boring Applications

Anywhere there's a pin bore or bearing bore that's worn out of round, line boring is usually the answer. Here are the most common jobs we handle.

Excavator Boom and Stick Pins

The boom-to-stick and stick-to-bucket pin bores on excavators wear fast under load. We restore them back to spec so your pins fit tight and your machine moves smooth again.

Bucket Pivot Bores

Sloppy bucket pivots cause all kinds of problems - poor breakout force, accelerated pin wear, and rough control response. Line boring the pivot bores fixes that without replacing the bucket or stick.

Dozer Blade Cylinder Bores

Dozer blade cylinder mounting bores and pivot points wear out over years of hard use. We restore the bore geometry so the cylinder mounts solid and the blade behaves like it should.

Loader Lift Arm Pivots

Wheel loaders and skid steers put serious stress on their lift arm pivot bores. When wear adds up, you feel it in the way the arms move. We bring those bores back into round and sized correctly.

Bearing Bore Restoration

Worn or damaged bearing bores in gearboxes, housings, and structural components can be line bored back to the right diameter so a properly sized bearing seats and holds like new.

Custom and One-Off Bore Work

Got something that doesn't fit neatly into a category? Bring it to the shop or describe it over the phone. If a bore needs to be machined or restored, there's a good chance Matt can sort it out.

How It Works

From Worn Out to Back in Spec

Line boring sounds technical, and it is - but the process from your call to the finished repair is pretty straightforward.

Call and Talk Through the Problem

Give Matt a call and describe what you're dealing with - excessive play in the linkage, a worn pivot point, or a bore that's been damaged. He'll ask a few questions to figure out whether line boring is the right fix and what it'll take.

Machine Assessment

Matt inspects the worn bore in person, measures the wear, and confirms what needs to be done. This is where you find out exactly what the repair involves and get a straight quote before any work starts.

Precision Machining

Using line boring equipment set up directly on the machine, Matt bores the worn area back to the correct geometry and tolerance. Everything is measured and checked throughout the process to make sure it comes out right.

Fresh Pin and Bushing, Ready to Work

Once the bore is restored, a new pin and bushing go in and fit the way they're supposed to. The machine goes back to work tighter and smoother than it's been in a long time - at a cost that makes a lot more sense than replacing parts.

Why Choose Us

Save Thousands Compared to Replacement Parts

A replacement excavator boom or loader lift arm can run tens of thousands of dollars before you even get to installation. A whole new machine is even more. Line boring lets you keep the equipment you've already got and get more years out of it - as long as the structure is still sound. Matt has seen it firsthand: machines that looked like they were headed to the scrap pile came out of the shop tight, accurate, and running strong after a line boring job. It's one of those services that doesn't get enough attention but pays for itself many times over.

Restores worn bores to correct tolerances without replacing the whole component
Dramatically cheaper than buying replacement booms, sticks, buckets, or frames
Can be done on-site or in the shop depending on the equipment and the repair
Extends the working life of equipment that still has plenty of good structure left
Precision machining - not a rough fix, but a proper, measured repair
Covers Union County, Mecklenburg County, Cabarrus County, Stanly County NC, and Chesterfield and Lancaster Counties SC
Pairs well with welding and fabrication if structural repairs are needed at the same time

FAQ

Line Boring Questions

Here are some of the things people usually ask when they first hear about line boring.

What is line boring and why does it matter?

Line boring is a precision machining process that restores a worn bore - like a pin bore or bearing bore on heavy equipment - back to the correct size and shape. Over time, bores wear out of round from constant load and movement. When that happens, pins and bushings don't fit right anymore, which causes accelerated wear and eventually component failure. Line boring fixes that problem without replacing the whole part.

How much can line boring save compared to buying new parts?

It depends on the equipment, but the savings are usually significant. A replacement excavator boom or stick can cost anywhere from $5,000 to $30,000 or more depending on the machine. Line boring the worn bores typically costs a fraction of that. Even on smaller equipment, restoring a pivot bore is almost always cheaper than replacing the arm, bucket, or cylinder that houses it.

Can you do line boring on-site, or does the machine have to come to your shop?

Both options are available. For larger machines that are difficult or expensive to transport, Matt can come to your job site or yard and do the boring there. For smaller components or situations where shop access makes more sense, you can bring it to him in Marshville. Either way, the quality of the work is the same.

What types of equipment do you do line boring on?

Mostly heavy construction and excavation equipment - excavators, bulldozers, wheel loaders, skid steers, backhoes, and similar machines. The most common jobs are excavator boom and stick pin bores, bucket pivots, dozer blade cylinder bores, and loader lift arm pivots. If you've got something else in mind, just call and describe it.

How do I know if line boring is the right fix for my equipment?

The clearest signs are excessive play or slop in the linkage, visible wear on pins and bushings, bucket or blade movement that feels loose and uncontrolled, and pins that are difficult to remove because the bore has worn out of round. If you're seeing any of those, it's worth a conversation. Matt can look at it and tell you whether line boring makes sense or whether something else is going on.

Do you also handle the pins and bushings, or just the boring?

We handle the whole job. The bore gets machined back to spec, and then a fresh pin and bushing go in so everything fits properly. You're not left trying to source hardware on your own - it's a complete repair from start to finish.
