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, Gillintown, 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.

You don’t need to search far for a Diesel Mechanic who actually shows up prepared. We’ve built our business on rolling directly to you with everything necessary to diagnose and fix the issue roadside. Our mobile crews know the roads between Gillintown and Gillintown by heart. They’ve handled mid-haul breakdowns outside Falls Creek, after-hours calls in Luthersburg, and long-wait turnarounds off exit 120. If the truck can be fixed where it stands, we’ll make it happen right there.
Mobile service? Yep. Full repairs at our Gillintown shop? Absolutely. We know diesel because that’s all we do, every day, from the cab to the tail. You won’t get passed around. You’ll get a mechanic who knows what they’re doing and brings the gear to back it up. So stop Googling and start dialing. We’re local. We’re fast. And we’ve already fixed a rig just like yours this morning.
At our Dale Road shop, trucks come in beat up from the road: tired tires, cracked lines, rusted bolts, and seized brakes. Just name it, we’ve seen it all. The building itself feels like a second home for diesel techs, with bays lined with welding rigs and shelves stacked with new and retread tires in every size from LP22.5 to 445/50R22.5. This is where the challenging jobs happen: structural repairs, frame rail swaps, axle spindle replacements, and complete engine rebuilds. Each step is about getting rigs back to running condition without shortcuts.
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 Gillintown’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? Oil changes, filters, tires: we knock that out without slowing you down. Serious repairs? Think electrical troubleshooting, frame rail replacements, brake jobs, and cooling system failures. 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?
