Finished up a complete rewire on this Trail King flat deck today! 🔧

Between multiple non-working lights, visible wiring damage, and lights that were overall pretty dim, the best route was to start fresh.

We stripped out the old wiring and completed a full trailer rewire, getting everything cleaned up and working like it should again.

Sometimes chasing one electrical problem after another just doesn’t make sense — starting fresh gives you a cleaner, more reliable setup and eliminates a lot of future headaches.

Another one finished up and ready to get back to work!

🔧 TOP GEAR DIESEL IS HIRING — 2 POSITIONS AVAILABLE 🔧

We’re looking to add two dependable people to our team at Top Gear Diesel in Newburg, MO.

We’re a privately owned diesel repair shop working on a wide variety of equipment — Power Stroke, Cummins, Duramax, semis, dump trucks, tractors, construction/ag equipment, and more. Our work ranges from general maintenance and diagnostics to fuel systems, suspension/steering, engine work, clutches, driveline repairs, electrical, and major repairs.

🔹 SHOP HELPER — Starting at $18/hr

This is a great opportunity for someone wanting to get their foot in the door of the diesel mechanic world.

We’re looking for someone who:

* Can identify and properly handle common tools
* Is comfortable lifting heavy parts/equipment
* Can stay busy, keep the shop organized, and be an extra set of hands when needed
* Shows up ready to work and is willing to learn

For the right person, this position offers plenty of room for pay raises and hands-on education, with the opportunity to grow into a full-time mechanic position.

🔹 FULL-TIME DIESEL MECHANIC — Starting at $25/hr+

Previous mechanical experience is required. You don’t have to have experience with every type of truck or piece of equipment we work on, but you must be able to independently work your way around an engine and confidently complete repairs.

Experience and having your own tools will be reflected in your pay. The more you bring to the table, the more earning potential there is.

📍 Newburg, MO
🕖 Monday–Thursday | 7 AM–6 PM

We believe a good employer/employee relationship goes both ways. Communication is huge for us. We expect honesty, dependability, effort, and communication from our employees, and we work hard to give the same in return.

If you’re looking for a shop where you can learn, make good money, grow your skills, and become part of a team instead of just another employee number, send us a message with your experience and which position you’re interested in.

🚜 John Deere 6135E back under the knife!

This 6135E came into the shop needing some major drivetrain work. We tore into it and replaced the high/low clutch along with the PTO bearings to get it back in working order.

Jobs like this are a good reminder that we don’t just work on pickups and semis — Top Gear Diesel works on tractors and heavy equipment too.

From diagnostics and repairs to major tear-downs, we’re equipped to handle the jobs that keep your equipment working when you need it.

🚤⚡️ Bringing This ShoalRunner Into the Modern Age! ⚡️🚤

This ShoalRunner jet boat is getting a complete electrical and dash upgrade to improve reliability, functionality, and peace of mind on the water.

Here’s what’s being installed:
✅ New gauges
✅ New fish finder

A clean electrical system is just as important as a strong engine. Replacing aging components and organizing the wiring helps eliminate electrical gremlins while giving the owner dependable performance every time they launch.

🔧 Fixing the Problem, Not Just the Symptoms. 🔧

This vehicle came in with intake-related issues, and our technicians went to work.

We removed the intake manifold, thoroughly cleaned the sealing surfaces, installed new intake manifold gaskets, and reassembled everything to factory specifications. Taking the extra time to properly prep the mating surfaces helps ensure a long-lasting repair, not a temporary fix.

A leaking intake gasket can cause:
✔️ Vacuum leaks
✔️ Rough idle
✔️ Check engine light
✔️ Reduced performance
✔️ Poor fuel economy

At Top Gear Diesel LLC, we believe quality repairs start with attention to detail. Whether it’s routine maintenance or more involved engine repairs, we take pride in doing the job right the first time.

⚡️ Small Parts. Big Difference. ⚡️

This vehicle came into the shop for a new set of spark plugs and ignition wires, and the difference speaks for itself.

Take a look at the comparison between the old and new spark plugs. Over time, worn plugs and deteriorated wires can lead to:
✔️ Engine misfires
✔️ Rough idle
✔️ Poor fuel economy
✔️ Hard starting
✔️ Reduced performance

Replacing these components at the recommended service interval helps keep your engine running smoothly and can prevent more expensive repairs down the road.

Whether you need routine maintenance or major engine repairs, Top Gear Diesel LLC has you covered.
