Hydraulic System
Repair
Pumps, cylinders, valves, hoses, motors — CTR provides complete hydraulic system diagnosis and repair for dump trucks, liftgates, refuse trucks, wet line kits, and all commercial applications.
Hydraulic System Experts
Commercial vehicle hydraulic systems power critical functions — dump body hoists, liftgates, refuse collection, wet line kits, and specialty equipment. When these systems fail, the vehicle cannot perform its primary function. Accurate diagnosis is essential because hydraulic symptoms can originate from multiple points in the circuit.
CTR uses pressure and flow testing instrumentation to isolate the actual cause — whether it's pump wear, cylinder seal bypass, valve leakage, or contamination. We service all hydraulic system types and fabricate replacement hoses on-site.
Located on Armentrout Drive directly off I-85 at Exit 58. All repairs backed by our 3-year, 36,000-mile warranty.
Pressure & Flow Testing
Systematic circuit testing to isolate the actual failure point.
3-Year, 36K Warranty
Industry-leading warranty on all hydraulic repairs. Parts and labor.
On-Site Hose Fabrication
Professional crimping equipment. Measure, fabricate, install same visit.
All Applications
Dump, liftgate, refuse, wet line, crane, winch — all hydraulic systems.
Complete Hydraulic Repair Services
From diagnosis to complete system overhaul. Click any service for details.
Systematic pressure testing at various circuit points, flow testing to quantify pump output, temperature monitoring, visual inspection, and electronic control diagnosis. Accurate diagnosis prevents replacing the wrong component.
Warning Signs of Hydraulic Problems
Slow Operation
Dump body raises slower, liftgate takes longer — losing flow (pump wear) or pressure (internal bypass).
Inability to Hold Loads
Raised body drifts down, liftgate won't hold position — internal seal bypass or check valve failure.
Visible Fluid Leaks
Any hydraulic fluid on ground, equipment, or fittings. Even small leaks reduce level and introduce contaminants.
Unusual Noise
Whining or growling from pump indicates cavitation, bearing wear, or gear damage. Banging indicates air in system.
Overheating
Fluid too hot to touch the reservoir — internal bypass, excessive restriction, or insufficient cooling.
Erratic Operation
Jerky movement, inconsistent speed — valve problems, air in system, or contamination.

Applications We Service
Understanding Your Hydraulic System
A hydraulic system converts engine power into controlled fluid force. The pump generates flow, valves direct it, cylinders and motors convert it to mechanical force, and the reservoir stores and conditions the fluid. Contamination is the #1 enemy of component life.
Hydraulic Pump
The heart of the system — generates fluid flow at high pressure. Gear, gerotor, or piston type. Driven by PTO, electric motor, or belt.
Hydraulic Cylinders
Convert pressure into linear force. Dump hoist, liftgate, outrigger cylinders. Seals separate high and low pressure sides.
Control Valves
Direct flow, regulate pressure, control speed. Manual, solenoid, or pilot-operated. Contamination is the #1 cause of valve failure.
Reservoir & Filtration
Stores fluid, settles air and contaminants. Filtration removes particles as small as 5 microns that cause accelerated wear.
Built for Heavy Duty
CTR's facility on Armentrout Drive has the pressure and flow testing equipment, hose fabrication capability, and bay space for complete hydraulic system service on all commercial vehicle types.
Fleet Hydraulic Programs
Scheduled fluid analysis, filter replacement, pressure testing, hose inspection, and preventive component replacement. One of the highest-ROI maintenance activities for hydraulic-dependent fleets.
