|wmiller said: (quoted from post at 01:26:12 01/25/14) Well, I really have nothing to lose by attempting a rebuild. Who knows, I may get lucky and be successful! If not I will have to figure out a way to modify the mount and install an after market cylinder......I guess the next move is to take it apart. I have done a lot of mechanical things but have never taken apart a hyd cyl before.|
Any help, advice or tips would be appreciated!!
The parts diagram I posted should be pretty self explanatory and the parts are generic items avaiable form a good MRO supplier - I get most of my stuff from Mcmaster Carr.
The trunion simply unscrews from the rod end of the cylinder and the piston cups (item #14) are sandwiched to the threaded end of the rod with some spacers/washers and a nut. Measure the old cups and get yourself a couple new ones.
Replace the chevron packing rings (item #8 ) with new packing. Measure the total height of the old stack and order a top and bottom ring plus enough intermediate rings to get the required thickness. The rings seal under compression and the new stack should be about 1 ring taller than the old one.
The rod wiper (item #6) may be harder to match up but it is not a pressure seal and if McMaster doesn't have one that will work and the old one is not badly damaged I'd reuse it. Total cost for the parts is probably about $30-$40 including the shipping.
PS> The o-ring is also a generic part available from the same source. Probably have to buy a bag of five ;-)
