Jumping Jack Tamper Repair

A malfunctioning jumping jack (also called a rammer or tamper) can delay your whole crew. Whether the engine won’t start or the machine is bouncing off balance, our technicians can get it compacting like new again.

Common services include:

  • Engine no-start and misfire diagnostics
  • Recoil and spark plug replacement
  • Carburetor cleaning and tuning
  • Air filter and fuel system service
  • Tamper plate and shock mount inspection

We also assess wear on impact systems and replace failing parts to prevent long-term downtime. If your rammer is vibrating too hard—or not at all—we’ll fix it fast.

Plate Compactor Service

Plate compactors are designed to take a beating, but they’re not immune to issues—especially when dust, fuel, or oil maintenance gets neglected. Our experienced team repairs both forward and reversible plate compactors, keeping them running safely and efficiently.

Our services include:

  • Engine servicing and compression tests
  • Belt and clutch adjustments
  • Eccentric housing maintenance
  • Lubrication and oil system checks
  • Plate inspection and vibration tuning

Whether you’re prepping a foundation, laying pavers, or compacting soil, we’ll make sure your compactor performs to spec.

Jackhammer Repair and Diagnostics

Jackhammers take a serious beating—so when the motor gives out or the piston jams, it’s more than just inconvenient. We provide full repair service for both gas-powered and pneumatic jackhammers.

We handle issues such as

  • Hard-starting or low power
  • Compression loss or piston seizure
  • Vibration dampener replacement
  • Chisel and bit holder damage
  • Air or fuel delivery troubleshooting

We’ll make sure your jackhammer delivers force—not frustration—on every job.

Air Compressor Maintenance

Air compressors are essential to a wide variety of commercial tools and applications—but only when they maintain consistent pressure and engine output. If your compressor is surging, leaking air, or failing to build pressure, we can help.

Our services include:

  • Pressure gauge calibration
  • Regulator and tank valve replacement
  • Hose and fitting repair
  • Engine tune-ups and oil changes
  • Belt, pulley, and flywheel servicing

We also diagnose electric start issues and make sure safety valves and switches are functioning correctly.
