If your RGN won’t detach, lift, or lock properly, we’ll get it functioning safely and reliably.
Expert RGN Trailer Repair Services
RGN trailers take a tremendous beating. These heavy-haul trailers routinely move massive excavators, dozers, cranes, pavers, and industrial machinery. Over time, the stress causes hydraulic failures, structural cracks, and mechanical problems that require specialized repair—not just standard trailer service. We service all major RGN manufacturers, including XL Specialized Trailers, Fontaine, Trail King, and Talbert.
Complete RGN Trailer Service & Repair
From hydraulic system failures to structural damage and brake issues, J&A Fleet Maintenance & Repairs offers full-service solutions for RGN and lowboy trailers. We work on all major RGN brands, including XL Specialized Trailers, Fontaine, Trail King, and Talbert.
Hydraulic System Repair & Troubleshooting
We service all hydraulic components involved in raising, lowering, and locking the gooseneck, including:
- Hydraulic hoses & fittings
- Contaminated or low fluid systems
- Slow, weak, or non-responding neck movement
If your neck won’t detach, lock, or lift properly, we’ll get it functioning safely.
Structural & Welding Repairs
Heavy-haul loads can cause structural damage over time. We provide complete repair solutions for RGN trailers, lowboys, Landoll trailers, and Cottrell car haulers We repair:
- Damaged locking mechanisms
- Stress fractures from overloading
Our welding and fabrication ensure your trailer stays strong, safe, and road-ready.
Electrical, Axles & Brake System Repairs
We also handle the critical systems that keep your RGN DOT-compliant and ready for the road:
- Brake chambers, shoes & drums
We make sure your heavy-haul setup is reliable from front to back.
Pony Motor Repair (Auxiliary Engine Systems)
Many RGN trailers rely on pony motors to power hydraulic functions. These small gas or diesel engines are known for issues like no-starts, fuel problems, weak output, and pump failure. J&A Fleet repairs all pony motor types, including Honda, Briggs & Stratton, Yanmar, Kubota, Kohler, and more.
Common pony motor services:
- Carburetor & fuel system cleaning
- Starter & charging system repair
- Hydraulic pump coupling issues
- Engine tune-ups & rebuilds
- No-start or low-power conditions
If your pony motor isn’t giving you the power you need, we’ll restore it fast.
PTO System Repairs (Truck-Powered Hydraulics)
Many modern RGNs use a PTO-mounted hydraulic pump driven by the tractor. When this system fails, the entire trailer becomes inoperable. We diagnose and repair:
- Bad solenoids or electrical faults
- Low hydraulic pressure or flow
- Broken gears or internal failures
- Hydraulic pump replacement
We get your hydraulic system working smoothly—whether powered by your truck or an auxiliary motor.
