Our Mobile Hydraulic Services
Hydraulic System Diagnostics
Our technicians utilize advanced diagnostic equipment to accurately identify hydraulic system issues. We bring portable pressure gauges, flow meters, temperature sensors, and contamination testing equipment to perform comprehensive system analysis. Our systematic troubleshooting approach identifies the root cause of failures, not just the symptoms, ensuring effective repairs that resolve underlying issues and prevent recurrence.
Hydraulic Hose Fabrication & Replacement
Hydraulic hose failures are among the most common emergency repairs. Our mobile service vehicles are equipped with hose crimping machines, a comprehensive inventory of hose materials in various sizes and pressure ratings, and a wide selection of fittings to fabricate custom hydraulic hoses on-site. We can quickly replace damaged hoses with properly rated assemblies that meet or exceed OEM specifications, getting your equipment back in service with minimal downtime.
Hydraulic Cylinder Repair
Our mobile hydraulic technicians can repair many hydraulic cylinders on-site without removing them from your equipment. We perform cylinder rod repair, seal and packing replacement, gland and piston rebuilds, and complete cylinder disassembly when required. For cylinders requiring machining or welding repairs, we can remove and transport them to our fully-equipped shop, then return and reinstall them upon completion of repairs.
Hydraulic Pump & Motor Rebuilds
When hydraulic pumps or motors fail, our technicians can often rebuild them on-site. We service all major types including gear pumps, vane pumps, piston pumps, and orbital motors. Our service includes disassembly, inspection, component replacement, reassembly, and testing to verify proper operation. We stock common replacement parts for popular pump and motor models to expedite repairs and minimize downtime.
Hydraulic Valve Service
Faulty control valves often cause hydraulic system performance issues. Our technicians service directional control valves, pressure control valves, flow control valves, proportional valves, and cartridge valve systems. We can disassemble, clean, inspect, and rebuild valves on-site, replacing worn components and adjusting settings to restore proper functionality. Our service includes complete testing to verify valve operation and system performance.
Hydraulic System Filtration & Fluid Service
Contaminated hydraulic fluid is a leading cause of component failures. Our mobile fluid service includes complete system flushing, filter replacement, reservoir cleaning, and fluid replacement with the appropriate ISO-rated hydraulic oils for your equipment. We can perform contamination testing and analysis to identify issues before they cause damage, and implement filtration upgrades to improve system reliability and extend component life.
Hydraulic System Repairs & Modifications
Our technicians can perform complex hydraulic system repairs and modifications on-site, including pipe and tube fitting replacement, manifold repairs, cooler service, accumulator charging, and control system adjustments. We also install performance upgrades, efficiency improvements, and system modifications to better match your operational requirements. All work is performed to industry standards with proper pressure testing and leak verification.
Preventive Maintenance Programs
Prevent costly hydraulic failures with our scheduled preventive maintenance programs. We perform comprehensive system inspections, fluid analysis, filter replacements, pressure and flow testing, and component assessments to identify and address developing issues before they cause failures. Our preventive approach helps maximize equipment uptime, extend component life, and reduce overall maintenance costs.

Customer Testimonials
We had a major cylinder failure on our excavator at a remote construction site. MTS had a hydraulic technician to us within 2 hours with a service truck that was better equipped than most shops I've seen. He diagnosed a seal failure, had the parts with him, and rebuilt the cylinder right on the machine. The quality of work was excellent, and getting the repair done on-site saved us thousands in equipment transport costs.

Our systematic diagnostic approach includes both component testing and system-level analysis to identify the root cause of failures, not just the symptoms. This ensures our repairs address the underlying issues and prevent recurrent problems.
Based on our extensive field experience, the primary causes of hydraulic failures include:
- Fluid Contamination (70-80% of failures): Particulate contamination causes accelerated wear, valve sticking, and reduced efficiency. Water contamination leads to corrosion, oil degradation, and cavitation.
- Overheating: Excessive temperatures break down hydraulic fluid, damage seals, and cause internal leakage.
- Improper Operation: Operating equipment beyond design limits, improper startup procedures, or bypassing safety systems.
- Poor Maintenance: Neglected filter changes, improper fluid levels, and failure to address minor issues before they escalate.
- Component Wear: Natural wear of pumps, motors, valves, and cylinders over their service life.
Our preventive maintenance approach focuses on addressing these common failure modes:
- Contamination Control: Implementing proper filtration, regular fluid analysis, improved breather systems, and proper fluid handling procedures
- Temperature Management: Ensuring adequate cooling, proper fluid selection, and addressing causes of excess heat generation
- Proactive Maintenance: Scheduled inspections, filter changes, and addressing minor issues before they cause failures
- Operator Training: Proper operating procedures, recognizing warning signs, and appropriate equipment use
- System Monitoring: Implementing pressure, temperature, and contamination monitoring systems for early problem detection
Our hydraulic preventive maintenance programs are customized to your specific equipment and operating conditions, focusing on the most common failure points in your systems to maximize reliability and component life.
Yes, we offer comprehensive hydraulic preventive maintenance programs designed to maximize system reliability and extend component life. Our programs include:
- Scheduled Inspections: Regular system evaluations to identify developing issues before they cause failures
- Fluid Analysis: Regular oil sampling and laboratory testing to monitor fluid condition, contamination levels, and wear indicators
- Filter Management: Scheduled filter replacements and upgrades to maintain proper system cleanliness
- Performance Testing: Regular pressure, flow, and temperature measurements to track system efficiency and detect degradation
- Minor Repairs: Addressing leaks, loose fittings, and other minor issues during scheduled service
- Reservoir Service: Periodic cleaning, breather replacement, and fluid exchange
- Cooler Maintenance: Cleaning and inspection of heat exchangers to ensure proper cooling
- Documentation: Detailed service records and performance tracking for each system
Programs can be customized based on your equipment type, operating conditions, and budget. We offer both time-based schedules (monthly, quarterly, semi-annual) and usage-based intervals (operating hours or cycles).
Clients utilizing our preventive maintenance programs typically see a 60-70% reduction in unexpected hydraulic failures and a 25-30% increase in component life, delivering significant return on investment through reduced downtime and repair costs.
