Today's video covers the process I use to disassemble, repack and reassemble the typical hydraulic cylinder on the loader tractors. It's shown to be a project almost anyone with a home shop can accomplish as long as ONE specific tool is available. That tool is the correct 'spanner' wrench to fit the dimension of the particular cylinder. Not all cylinders utilize the spanner, some actually have a huge nut cast into the gland making it much easier in most cases.
The replaceable internal components are specific to each cylinder and available in kit form. Many parts will interchange with others, but it is best to order exactly what repair kit is made for the cylinder you are rebuilding. As long as the cylinder comes apart easily, the repair is not beyond anyone with just the basic mechanical knowledge.
The main thing to be concerned about is cleanliness. Keep dust, dirt and debris off and out of the parts because all foreign materials entering the rebuilt component will ultimately end up as sludge in the reservoir or doing damage to the hydraulic pump while circulating with the oil. The best case scenario is that it will prematurely plug or restrict the filter necessitating early replacement.
This particular one turned out to be a relatively easy disassembly. They are not all this easily disassembled. Some require extreme measures like being secured with a welded bracket to the metal table then unscrewing with a pipe wrench and hydraulic jack. We have even welded iron to the gland's face to give a greater 'perch' for the pipe wrench. THAT was an extreme case, but it had to be done.
Smaller cylinders for some other applications are easily disassembled because of their rod and flange design. But those do have their own kind of issues, however in general they are simple to service.
