Hyrdraulic Cylinder Repair Machine

Hydraulic cylinder repair machine - Hydraulic cylinder repair bench

This machine is intended for all handling of small and medium-sized hydraulic cylinders. It has very great potential for variations in use. For cylinders to be disassembled that have a "locking ring top nut", turn the piston rod end to the left and pull out the piston rod a bit and leave the cylinder on support jacks. Attach the cylinder side to the large chuck. Then mount the 2 push pins that fit in the support doll's tool groove on the support dock. After the outer locking ring has been removed, pressure with the axial movement against the top nut and if it does not want to release, it may need a stroke with a small sledgehammer. Cylinders that have a screw top nut, you turn the top nut to the right and then use the self-tightening large chuck. You can start with rotation on the chuck and if it does not have the strength you can drive with power rotation and when it loosens you continue with rotation. It sometimes happens that the top nuts "cut" and then there is usually not much to do other than turning out the top nut.

The machine can otherwise be used in many different ways and the only limitation is your own imagination. When loosening piston nuts on eg Caterpillar piston rods, you can attach the link head to the support dock and then use the cones and standard jaws in the chuck. In order to be able to unscrew nuts on piston rods more quickly, you can order nut grips which you fasten in the chuck. These plates are cut out with a cnc-controlled plasma cutter and can be ordered with different grip widths from us. These nut plates save both a lot of time and money as you do not have to change all the jaws.

When you have assembled a cylinder, you want to test press and therefore there are 2 hoses with quick couplings and nipples and you can then connect the quick couplings with the included nipples ½ ”or 3/8” R-thread. The test pressure is maxed out with the pressure given by the hydraulic unit. If you want to test pressure with higher pressure, a hand pump of some kind is also recommended, which is also switched on with a quick coupling.

For collecting waste oil, the machine has a collecting trough that runs on wheels and there is also a connection for any drain pump. The machine can also be equipped with an extension part that can be mounted on the frame beam to be able to handle extra long cylinders.

There are some standard tools for the support dock. Cones for gripping link heads and toothed grips for various purposes, e.g. pins to push in "locking ring nut". You can also find your own accessories for different holdings. The stroke of the support manikin is as long as the machine, but the stroke of the cylinder that pulls the beam is 700 mm. You must therefore make a "retake" with the pins that are on each side of the support doll when you no longer come. The support jacks also have pins that lock against the beam to be able to follow when disassembling and assembling cylinders.
