Heavy Equipment Repairs

I provide mobile repair and diagnostics that keep your equipment working without the delays of hauling or waiting on a dealer. Hydraulic leaks, electrical faults, and mechanical breakdowns are handled directly in the field, so your operation stays productive.

With onboard OBD diagnostics, I identify sensor failures, electrical codes, and Tier 4 aftertreatment issues before they shut you down. No guessing, no wasted parts — just precise troubleshooting and fast solutions delivered where the work happens.

Regen faults, no‑starts, and active fault codes show up right when you’re prepping for PMI, DOT, or CARB inspections — the moments where accuracy matters most. This section shows how I approach diagnostics with intent: decoding signal dropouts, chasing voltage through a harness, and proving results. No speculation. No vague summaries. Just real service stories, rooted in experience and geared toward outcomes.

Tractor & Farm Equipment Repair

Learn about Farm Equipment Solutions

OnSite Diesel Solutions provides mobile repair for tractors and farm equipment across Yuba and Sutter Counties — no trailering, no shop delays.

Whether you’re moving hay, digging a hole, grading a driveway, or feeding livestock, I can help keep your equipment ready to work. I service older tractors, compact rigs, and utility machines that still get the job done — handling no-starts, loss of lift, fuel issues, and hydraulic leaks right in the field. If something’s off — slow to start, running rough, or losing power — I bring the tools to track it down. When needed, I run onboard diagnostics to catch electrical faults, fuel delivery problems, or sensor issues that don’t show up in a visual check.

You don’t need dealership delays or vague answers. You need someone who shows up, finds the problem, and gets your machine back to work.

Advanced Diagnostics
Dealer-Level, On-Site

OnSite Diesel Solutions provides Advanced Diagnostics on-site across Yuba and Sutter Counties—no hauling, no waiting, no guesswork. Our diagnostic platform supports all three branches of service—Heavy Equipment, Big Rigs, and Farm Machinery—so no matter what you're running, we bring answers directly to the field. We isolate regen faults, ECU dropouts, sensor confusion, and no-starts using Jaltest multi-system diagnostics calibrated for real-world conditions. Every scan includes an official system health report, complete with fault codes, wiring references, and system status. We break it down line by line—what the codes mean, what the symptoms say, and what actions are required. If the repair can be done safely on your own, we provide self-help walkthroughs so you’re not left guessing. If it’s a fix that needs our hands, we’ve already got the roadmap built. Dealer-level testing. Field-ready precision. A solution that makes sense.
