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.
When the damage runs deeper, like a turbo failure or blown cooling line, we handle the tow back to our Dale Road facility in Narrows Creek. Our shop spans 40,000 square feet and is built for full teardown work, including axles, U-joints, and frame rail replacements. Every move is about cutting downtime, keeping freight moving, and getting your unit road-ready again.

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 Narrows Creek and Narrows Creek 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.
We keep common parts stocked, and we know which issues tend to show up in this region. Our team will show up, run the diagnostics, and start the repairs right away. We come out, plug in, climb under, and fix what’s stopping you. If the truck needs a tow, we get that moving, too. We’re direct about what’s wrong and clear about what’s next. For us, nearby doesn’t mean close on a map; it means immediately ready to respond.
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.
We’ve been turning wrenches in central Pennsylvania long enough to know that every hour off the road hits your bottom line. That’s why our process is streamlined from check-in to completion. We coordinate directly with your fleet manager or insurance rep and keep updates flowing. The sooner you roll out of our lot, the sooner you’re earning again. And we love that for you!
Bigler Boyz handles diesel like it’s supposed to be handled: hands-on, with no steps skipped. And you’ll also find preventive work in the mix: oil changes on schedule, coolant system checks before summer hits, and winter prep that doesn’t just stop at fuel conditioner. We know what local roads and hills can do to a poorly maintained rig, and we help you stay ahead of it. That’s why we’ve been Narrows Creek’s trusted name in diesel repair for decades.
