Maximum Power, Zero Leakage: Expert Hydraulic Service

In industrial operations, hydraulics are the muscle, delivering immense power and precision to
critical machinery. When hydraulic cylinders, pumps, or valves fail, the resulting downtime can
be costly and crippling.

A+ Quality Gearbox Repair is your trusted Southern California solution for comprehensive
hydraulic repair and restoration. Leveraging our in-house, certified machine shop capabilities,
we go beyond simple seal replacement to deliver high-precision repairs that guarantee
maximum system performance, minimal leakage, and extended component life.

Our Full-Spectrum Hydraulic Repair Process
We control every aspect of the repair, from inspection to final testing. Our commitment is to restore your hydraulic components to OEM tolerances and performance specifications.

Our hydraulic repair services include:

● Failure Analysis and Diagnostics: We thoroughly inspect all components—including
rods, barrels, heads, and pistons—to determine the root cause of wear, scoring, or
failure. This ensures the problem is fixed permanently, not temporarily.

● Cylinder and Rod Restoration: We specialize in addressing critical wear areas. This involves straightening bent rods, honing or polishing scored cylinder walls, and applying
superior finishes like hard chrome plating or thermal spray to restore rod surfaces to a hardness that often exceeds the original manufacturer’s specification.

● Precision Machining: Our in-house machining capabilities allow us to fabricate new
glands, pistons, and custom shafts, ensuring perfect fit and eliminating delays
associated with sourcing obsolete or specialty parts.

● High-Performance Sealing: We install only high-grade, application-specific seals,
wipers, and packings to ensure zero leakage and prevent system contamination, which
is vital for long-term reliability.

● Pump and Valve Rebuilding: We rebuild hydraulic pumps and motors, restoring critical
clearances and replacing worn elements (like vanes, gears, and pistons). Valves are
disassembled, cleaned, and tested for proper flow and pressure control.

● Testing and Certification: Every repaired unit undergoes rigorous pressure testing on
our dedicated test bench to verify performance under load, pressure, and cycle
conditions before it is certified and returned to your facility.

We Repair All Major Hydraulic Components

We service a wide variety of hydraulic components used across construction, manufacturing, material handling, and processing industries:

● Hydraulic Cylinders: Single-acting, double-acting, telescopic, tie-rod, and welded
cylinders.
