About Our Heavy Equipment Repair Services
Amoretti Diesel Repair and Service works on construction and earthmoving equipment used by contractors, landscapers, farmers, and other equipment owners. We inspect the reported problem, identify the affected system, and recommend repairs based on the machine's condition rather than replacing parts without a clear diagnosis.
- Skid Steer Repair: Diagnose and repair hydraulic pump problems, axle failures, starter issues, and related mechanical concerns
- Hydraulic System Repair: Troubleshoot leaks and performance problems involving pumps, hoses, fittings, and cylinders
- Electrical Troubleshooting: Trace battery, alternator, starter, wiring, and other electrical faults that affect starting, charging, or machine operation
- Cooling and Overheating Concerns: Investigate rising operating temperatures and related cooling-system problems before continued operation causes additional damage
- Power and Performance Problems: Diagnose machines that lose power, struggle under load, or no longer operate as expected
- Preventive Maintenance: Perform oil changes, filter replacements, and routine equipment service based on the machine's needs
Construction and Earthmoving Equipment We Repair
Heavy equipment operates under sustained hydraulic demand, heavy loads, dust, long hours, and repeated digging or lifting cycles. Those conditions can affect several systems at once, so the reported symptom should guide a complete inspection.
- Excavators: Hydraulic problems, leaks, starting faults, electrical issues, overheating, and loss of power
- Skid Steers and Skid Loaders: Hydraulic, axle, starter, electrical, and related mechanical repairs
- Loaders: Hydraulic, cooling, electrical, power, and other performance concerns
- Other Earthmoving Equipment: Mechanical and system faults that cause leaks, unusual operation, or unexpected downtime
Signs Your Heavy Equipment Needs Service
- Slow Hydraulic Functions: Buckets, arms, attachments, or lift functions move more slowly or respond differently than normal
- Visible Fluid Leaks: Oil around hoses, cylinders, fittings, or pumps can indicate a hydraulic problem that needs inspection
- Hard Starting: Repeated no-start or slow-start conditions may involve the battery, starter, charging system, fuel system, or wiring
- Loss of Power Under Load: An excavator, skid steer, or loader struggles with work it previously handled normally
- Overheating: Operating temperature rises during normal use or the machine cannot maintain its usual temperature range
- Warning Lights or Electrical Faults: Intermittent warnings, control problems, or charging issues interfere with machine operation
- New Noise or Vibration: A change in sound or movement can indicate wear, looseness, or another developing mechanical issue
