Hydraulic Cylinder Repair Tips

In both mobile systems and industrial systems, hydraulic cylinders are essential for picking, lifting, and gripping. That means they are a crucial component of any hydraulic system because they allow for the elimination of gears and levers. All hydraulic systems are comprised of components such as valves, filters, pumps, and cylinders, and hydraulic cylinders tend to be some of the simplest components of the entire system.

For the most part, failure on hydraulic cylinders occurs as a result of damage to the seals or fluid contamination. It’s also possible that there will be an internally corroded barrel, or that the hydraulic cylinder is exposed to either chemical influences or extreme temperatures. Regardless of the cause of the damage, there are some important procedures you should be aware of when attempting hydraulic cylinder repair.

Before you begin the process, make sure that all surfaces have been properly cleaned, and that all hydraulic hoses and plugs have been disconnected. Then you should drain all hydraulic fluids from inside the cylinder, and you can begin your repairs. The tools which are generally needed for hydraulic cylinder repair are a proper seal kit, screwdriver, punch, rubber mallet, torque wrench, pliers, and emery cloth.

The steps involved in cylinder repair consist of disassembling the cylinder itself to diagnose the failure because, repairing or replacing any components which have malfunctioned, and then rebuilding the cylinder.

6 Things you need to keep in mind when going through hydraulic cylinder repair

#1 The Effects of Weather

When you’re replacing seals, remember that the seal will expand or compress in sync with environmental conditions

#2 Preventing Friction in Moving Parts

Hydraulic wear bands are generally used for guiding pistons, so assemble these because they will reduce metal-to-metal contact

#3 Visually Inspect for Damaged Parts

When you’re disassembling the hydraulic cylinder, make sure to check for other failed parts

#4 Look for Underlying Causes of Damage

When you have a premature failure of rod seals, that generally will indicate some kind of bend on the rod

#5 Always be Careful When Working with Moving parts

Large hydraulic cylinders generally use high tension springs, so be careful when handling these types of cylinders

#6 Use the Right Tool for the Job

Make sure to use the best fitting tools when you’re doing repair work because any kind of scratches on the cylinder will lead to issues like corrosion.
