Repair Process

Disassembly, Clean & Inspect – We will clean and evaluate each piece of equipment for 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.
Full Testing and Repair of Onboard Electronics – We will determine where problems may originate and address all issues by doing all repairs in-house.
Elimination of Scoring From Pistons and Shafts – Not only do 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.

Removal of Contamination – We remove contamination we find on the surfaces of different components to help extend the lifespan of the equipment.
Machine Work on Cylinders and Review of Shafts – 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.
Checking Fittings for Tolerance – We also check the fittings to ensure each one is within the range of allowable dimensions for certain specifications.

Three common checks are:
- 1. Pressure tolerance
- 2. Specification checks from 10,000 psi
- 3. Specification checks to 150 gpm flow
Resurfacing of All Contact Points – Resurfacing contact points helps remove the scratches and abrasions that occur with normal wear and tear, making the contact surfaces smooth once more. This process helps reduce friction and increase the efficiency of hydraulic equipment.
Replacement of Bearings and Seals – 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.
