What kind of repair services do you offer?
The Maverick Machine repair division focuses on repairing hydraulic cylinders used in material handling equipment (lift-gates, telehandlers, and forklift trucks), construction equipment, and heavy industry (oil rigs, cranes, off-road vehicles), as well as servicing and repairing industrial hydraulic pumps, motors, valves, and other hydraulic components.
Do you offer hydraulic cylinder honing?
Maverick Machine provides honing services in-house as part of the total process of repairing or rebuilding your damaged hydraulic cylinder.
What are the benefits of honing a hydraulic cylinder?
Professional cylinder honing is crucial for creating a secure seal and ensuring the smooth operation and prolonging the useful life of any hydraulic cylinder. Refinishing the cylinder helps to straighten the walls, enhance bore geometry, and provide sufficient crosshatch surface finish to facilitate optimal oil retention and ring support.
- The benefits include:
- Uniform wear
- Improved lubrication
- Extended seal life
- Correct geometrical issues
- Fix minor surface irregularities
Why should you repair a hydraulic cylinder after spotting an oil leak?
Beyond inspecting the hydraulic cylinder during scheduled maintenance, you may need to perform unplanned repairs if you notice external oil leaks. Leaks increase the risk of contaminants entering the system where they scratch the cylinder wall and cause other irregularities that accelerate seal wear and initiate internal leaks. Ultimately, the leakage will reduce the performance and service life of your cylinder.
What are the signs of damaged hydraulic cylinder parts?
If there is an eternal or internal leakage, the cylinder will need to be assessed. After disassembly, the seals and other parts of the cylinder will be inspected for signs of damage as below:
- Piston seal – a missing, eroded, or badly distorted piston seal could indicate that the barrel has bulged in service, or that it’s oversized. While replacing the piston seal can be a short-term solution, the barrel or cylinder should be replaced to prevent the problem from recurring.
- Rod seal – the rod seal can be distorted due to a bent rod or excessively worn guide brush, causing uneven weight on the rod seal, and ultimately failure. The root of the problem should be identified before replacing the rod seal.
- Rod – during cylinder repair, the rod will be checked for cracks and straightness and the necessary repairs made. If the chrome surface has minor scratches, it can be polished. It can also be rechromed if badly pitted or scored, or simply replaced.
- Head – if there’s a bush separating the cylinder rod and head, then the guide bush (wear band) should be replaced during cylinder repair. If there’s no bush, then the internal diameter of the head will be measured and the head replaced if it’s outside the recommended tolerance.
- Piston – minor scoring on the piston exterior is not detrimental, but a diameter that’s outside the recommended tolerance may require replacing the piston.
- Barrel – cases of scoring or pitting can be removed by honing. Otherwise the barrel must be replaced.
How do you order the right seals for a hydraulic cylinder?
Seals can swell or shrink in service, so you should avoid measuring old seals when ordering new ones. There is also the risk of an incorrect seal having been installed previously, which can cause ongoing problems. To ensure that you purchase the right seals, make sure to measure all seal grooves using a vernier caliper and provide our vendors with those readings.
