Middle of nowhere. Flashers on. Engine codes are screaming. We’ve rolled up on that scene hundreds of times. When your diesel rig quits in the middle of I-80, you need a fix that sticks. That’s what we do. Our mobile diesel trucks are stocked, staffed, and out the door fast – ready immediately to tackle coolant leaks, forced regens, electrical fails, air leaks, and more.
Each service truck carries everything needed to diagnose and repair on-site, including electrical gear, air fittings, spare hoses, and stocked tires. If the fix needs more room, we tow the truck to our Oshanter facility and move straight into the teardown process. Engines, radiators, and turbo systems get pulled and rebuilt by the same crew that answered the call. No delay. No handoff. Just work done until the truck moves again.

Stuck on the shoulder? We’re already rolling. All around Oshanter, PA, our Diesel Mechanics live on the road. They can help you with jump-starts in sub-zero temps, wiring faults in gravel lots, and blown tires at two in the morning near Exit 133. We always bring the garage with us: air tools, diagnostics, new and retread tires, coolant, and lighting gear. Every stop is handled with the urgency of a driver watching their logbook run out.
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.
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!
