When you bring your hydraulic or pneumatic equipment in for repairs, we’ll give it a comprehensive level of service that addresses your equipment as a whole, rather than as one broken part. Our hydraulics and pneumatic repairs follow a rigorous process that includes the following services:

When You Come to Us!

a. Disassembly.

The hydraulic repair process begins with a systematic disassembly process. Our practiced technicians remove each component and set it aside. A controlled, precise disassembly procedure helps ensure the equipment remains protected and scratch-free throughout the process. A controlled disassembly process also allows technicians to look over each component of the equipment and assess any damage or wear and tear they need to address. Meticulous disassembly is the first step toward a quality repair job, and it is a step our technicians approach with great care.

b. Cleaning and Inspection.

Cleaning and inspection are the next steps. Cleaning removes built-up oil, grease, dirt and other grime and allows the technician to see the components more easily — and a thorough, detailed examination of those components helps the technician locate the source of the problem and diagnose it accurately.
Generally, a technician will evaluate a piece of equipment for telltale signs of a problem, such as broken or swelling seals, worn-out piston rods, cracked welds, scored shafts and other clues about what may be amiss. During this inspection, the technician will also measure the equipment’s components and check the measurements against the manufacturer’s measurements.

c. Full Testing and Repair of Onboard Electronics.

After cleaning and inspecting the equipment’s components, the technician moves on to a thorough test of the equipment’s onboard electronics. Testing the electronic components helps the technician determine where problems may originate and offers clues about how to address issues. Once testing and diagnosis are complete, the technician can begin to repair the onboard electronics, if necessary. As with other components, we perform all electronic repairs in-house, so downtime will be minimal.

d. Elimination of Scoring From Pistons and Shafts.

As we repair hydraulic equipment, we also check the pistons and shafts for scoring or pitting. We then eliminate the scoring by using one of a few different methods. If the chrome surface of the piston rod contains small amounts of scoring, we may be able to polish the scoring out. Otherwise, we may re-chrome the piston rod. For other components of the piston or shaft, we may use a honing tool that allows us to hone away pitting and scoring and leave the parts looking and functioning like new.

e. Removal of Contamination.

During the hydraulic repair process, we also remove any contamination we find on the surfaces of different components. Sometimes chemical contaminants, such as corrosive cleaners, may build up on the components of hydraulic equipment. Or sometimes other contaminants, such as oil and grease, may accrue and gum up the parts. No matter how they originated, contaminants can interfere with the workings of your company’s hydraulic equipment, make it run less efficiently and lead to breakdowns.
Removing contamination helps extend the lifespan of the equipment.

f. Machine Work on Cylinders and Review of Shafts.

The next step is to perform machine work on the cylinder and check the shaft. The cylinder may need a new component or merely some minor reconditioning, and we can give it the service it needs. We can also replace broken shafts or repair the damage we find. Working on cylinders and shafts helps enhance the performance of the hydraulic equipment and extend its lifespan, as well.

g. Checking Fittings for Tolerance.

As we work on hydraulic equipment, we also check the fittings to be sure each one is within the range of allowable dimensions for certain specifications. The three most common checks are:

• Pressure tolerance.
• Specification checks from 10,000 psi.
• Specification checks to 150 Gpm flow.

We also take diameter tolerance and angle tolerance into account as we assess the fittings of hydraulic equipment. These checks help make sure the components fit together properly and the machine is capable of optimal performance.

h. Resurfacing of All Contact Points.

Resurfacing contact points is also a critical element of the repair process. Resurfacing contact points helps remove the scratches and abrasions that occur with normal wear and tear and make the contact surfaces smooth once more. This process helps reduce friction and increase the efficiency of hydraulic equipment.

i. Replacement of Bearings and Seals.

Replacing bearings and seals is the final component of the repair process. Worn-out bearings and leaking seals can quickly lead to equipment failure. Making sure these components are in good working order helps ensure the high performance and long lifespan of the equipment.
