Whether you're operating excavators, bulldozers, wheel loaders, skid steers, compact track loaders, articulated dump trucks, graders, trenchers, telehandlers, cranes, asphalt equipment, or concrete machinery, VTech Diesel has the experience to keep your equipment producing.

Our field technicians understand that construction equipment doesn't make money sitting on a jobsite waiting for repairs. That's why we provide rapid mobile heavy equipment repair with advanced diagnostic equipment capable of troubleshooting electrical systems, engine performance, emissions systems, cooling systems, DEF systems, fuel injection systems, aftertreatment components, air brake systems, powertrain issues, driveline failures, final drives, undercarriage wear, steering systems, suspension, PTO systems, and complete preventative maintenance programs. From a single skid steer to an entire fleet of earthmoving equipment, we help maximize uptime while reducing costly downtime.

Hydraulic System Repair & Diagnostics

Hydraulics are the heart of modern construction equipment, and when hydraulic performance suffers, productivity comes to a halt. VTech Diesel provides complete hydraulic diagnostics, hydraulic cylinder repair, hydraulic pump replacement, hydraulic motor repair, valve testing, hydraulic hose fabrication, hydraulic line repair, hydraulic leak detection, pressure testing, flow testing, and contamination analysis for virtually every type of heavy equipment. We diagnose slow hydraulics, overheating systems, loss of lifting capacity, drifting cylinders, weak travel motors, noisy pumps, cavitation, valve failures, and hydraulic pressure issues before they become catastrophic failures.

Our technicians service hydraulic systems found on excavators, backhoes, wheel loaders, skid steers, compact track loaders, bulldozers, cranes, telehandlers, forklifts, trenchers, directional drills, paving machines, milling machines, compactors, forestry equipment, vacuum excavators, utility trucks, bucket trucks, boom lifts, scissor lifts, and specialized construction machinery. Whether your equipment uses gear pumps, piston pumps, vane pumps, hydrostatic drive systems, proportional valves, load-sensing hydraulics, or electronically controlled hydraulic systems, we have the tools and experience to diagnose and repair them correctly.

Hydraulic contamination is one of the leading causes of expensive equipment failures. Metal contamination, moisture intrusion, worn seals, damaged hoses, clogged filters, failing pumps, and overheated hydraulic oil can destroy thousands of dollars in components if left untreated. VTech Diesel performs comprehensive hydraulic inspections, fluid sampling, filter replacement, flushing procedures, hose replacement, seal replacement, cylinder resealing, accumulator service, and complete hydraulic system restoration to help extend the life of your equipment while minimizing unexpected downtime.

From replacing a single leaking hydraulic hose on a skid steer to rebuilding complex hydraulic systems on large excavators and articulated loaders, our goal is simple—restore full hydraulic performance safely and efficiently. We understand that every minute your equipment is down costs money, which is why we focus on accurate diagnostics, quality repairs, OEM-quality components, and preventative maintenance solutions that keep your fleet operating at peak performance.
