Ed's Hydraulic Repair

Ed's Hydraulic Repair I am re-packing cylinders and replacing seals in Hydraulic Pumps and motors in the Nackawic area, pick up and delivery can be arranged.

From time to time I will also have used or rebuilt Hydraulic components to sell.

When we repacked these two hydraulic cylinders the rod seals were extruded. This can be caused by a few different things or a combination of side load, over pressuring, or excessive gap caused by wear. I installed a special rod seal to prevent this from happening again.

This one was a bit of a challenge when it came in. It is a steering cylinder off of an Allis-Chalmers Tractor. It appears someone previously machined the piston to try and get standard loaded u-cups to work. The piston is has a smaller outside diameter on the ends so the seals extruded under pressure. Since the piston had been modified we had a choice get a custom seal made or make a new piston to fit a standard seal like the seal with orange wear rings shown in the pictures. They decided to go for the custom seal that you see in the pictures (Red/Blue) and the cylinder went together nicely and tested good.

When this valve bank came in I thought it might be done for. I got it apart and cleaned up and had to replace the handle kits and spring center kits along with new seals. Now it's working with no leaks. The Main relief is set at 2500 psi and on the second spool there is an external port relief and the down function of the cylinder is reduced to 500 psi as you see in the video. It is used for a gooseneck trailer.

Having the right tool for the job makes things go much smoother. When the parts co-operate too that helps. :)

This Gresen 400 single spool valve was made before December 1989 and there is not a direct replacement. I installed new seals and replaced all the fittings and did a pressure test for leaks. The relief is only set at 900 psi, but that is all that is required for this application.

A Six spool Hydraulic Directional Control valve reseal. I replaced all the seals, there are about 60 o-rings and seals in this valve, cleaned up the spool positioning controls, replaced the spool ends, and reset the pressure back to 2200 psi on the main relief. Function test of pneumatic actuators and leak test.

A little easier to measure cylinders and certain components now with my new caliper.

A little 15 series Sunstrand unit I replaced the seals and bearings in. The shaft had to be repaired also.The tag says it was built in 1989. It's back on the skid steer and working good.
