Diesel problems don’t wait for good weather or daylight. More often than not, they happen during pouring rain, late at night, and you’re hauling on a tight deadline. We’ve responded in snow, mud, and middle-of-the-night calls because that’s when trucks fail. Our mobile crews bring what’s needed to the site: tools, parts, diagnostics, and the people who know how to use them. We’ve worked through forced regens, air leaks, dead starters, and faulty sensors. Diesel work takes follow-through, and we show up ready to get it done.
If the issue goes beyond a roadside fix, we move it straight to our shop on Dale Road, Cooper Settlement, PA. Our team is set up to start repairs without a pile of intake delays. We’ve got the space, the parts, and the staff to keep the work moving. Once your unit is in the bay, we start turning wrenches. We don’t waste time when a truck’s losing days.

If your search history reads "Diesel Mechanic near me," chances are something's leaking, grinding, or refusing to start, and you need real help fast. We’re close to I-80, which means we can reach you quickly and be fully stocked to do more than just look. Our trucks carry the tools for the job, and our techs don’t just inspect. They fix. We handle work on all types of diesel engines, and we’re ready for more than just code scans.
If not, we’ll pull you to the shop ourselves: no third-party handoff, no waiting on another truck. Inside, our technicians cover everything from oil changes and brake replacements to wiring repairs and computer diagnostics. It’s a full-service setup, tuned for heavy diesel work. You can count on us for clear communication and repairs that last long past the first run after the fix.
We’ve been in the game for decades, turning wrenches on everything from old-school mechanical Cummins to modern DEF-heavy powerplants. Walk into our shop and you’ll see a mix: classic rigs with hundreds of thousands of miles and newer trucks with blinking dash lights. Our crew speaks both languages: the seasoned techs and the sensor-savvy new school. We’ve seen just about every failure a diesel can throw. From injector issues to turbo failures, we’ve rebuilt, replaced, and reprogrammed them all. Our diagnostics don’t stop at the first code; we dig until we find the real cause. That’s why so many fleets across Central PA count on us when performance and uptime matter.
Drivers know us by name because we don’t do guesswork or delays. We get the problem solved and the rig back out. That’s what makes us Cooper Settlement’s go-to diesel shop. We work on what rolls in, and we stand behind what rolls out. If you’ve got diesel problems and you’re anywhere near Dale Road, pull in. We’re the ones who’ll get it right the first time because anything else is just wasting your time.
Our Bigler Boyz Diesel Mechanic services cover everything from day-to-day issues to full-blown breakdowns. Routine maintenance?

We've got the tools, the parts, and the hands to handle it. Need welding or fabrication? We're built for that, too. You can roll into our shop off I-80, Exit 123, or call for mobile diesel repair, and we’ll bring the tools to you. Downtime is not only annoying but also expensive. That’s why we stay ready, stocked, and sharp. Whether it's a fleet truck or a single owner-operator, we don’t cut corners or coast through the job. If your diesel rig needs fixing, we’ve got one question: where should we meet you?
