Expert Cylinder Repair for Every Application
Whether your hydraulic cylinder has a blown seal, bent rod, scored bore, or catastrophic failure, Hydramachine has the equipment, expertise, and parts to get it rebuilt and back in service. We repair cylinders for construction equipment, manufacturing presses, agricultural machinery, and every hydraulic application in between.
Every cylinder that leaves our shop has been repaired by experienced technicians, machined to specification, and pressure-tested at operating conditions. No shortcuts. No guesswork.
Before & After: Component Recovery
A full rebuild often starts with damaged components and ends with precision-machined replacements. The examples below show typical recovery work completed in our shop.
Cylinder Types We Repair
We work on all types of hydraulic cylinders regardless of manufacturer, age, or condition:
Single-Acting Cylinders
Rams, plunger-type cylinders, and spring-return configurations used in presses, lifts, jacks, and dump equipment.
Double-Acting Cylinders
The most common type in industrial and mobile applications. Full control in both extend and retract stroke.
Telescopic Cylinders
Multi-stage cylinders used in dump trucks, refuse packers, ejector trailers, and construction equipment.
Tie-Rod Cylinders
Standard industrial cylinders held together by external tie rods. Common in manufacturing and material handling.

Our 5-Step Repair Process
Every cylinder goes through the same proven process to ensure quality, reliability, and zero surprises on your invoice.
Intake & Assessment
We receive your cylinder, disassemble it using our 50,000 ft-lb disassembly machine, and perform a thorough inspection. We document all wear, damage, and needed repairs.
Estimate & Approval
You receive a detailed estimate with the scope of repair, parts needed, and expected turnaround time. We won't do any work without your approval.
Repair & Machining
Our technicians perform all repair work in-house. Machining, welding, honing, seal replacement, and component fabrication happen under one roof.
Assembly & Testing
The rebuilt cylinder is reassembled, filled, and test-cycled at operating pressures. We verify proper function, check for leaks, and confirm the cylinder meets specification.
Return to Service
Your repaired cylinder is finalized, documented, and ready for your team to place back in operation.
