Hello to all..I was searching the web for info on repair of some hydraulic cylinders and found this great site. I was raised on a farm and never lost my love for all things mechanical. We now have 10 acres north of town and I just can't keep away from a good project that has anything to do with machinery.
I bought an older model dump truck and kinda shot myself in the foot because I did not try to raise the bed and got side tracked cause the engine ran so good. Well, I got the beast home and discovered BOTH cylinders were busted,,,!!! It appears some water had gotten in the system and sat for some time and must have froze and busted the ends out. This dump truck lived at 7800 elevation. What is puzzling is that one broke on the rod packing end, and the other cyl. busted on the back end.??????
I dis-assembled them and there was rust in both of the cylinders and the ring was broke on one of the pistons. Cannot find any markings on either cyl.
The rod packing gland was pushed out on one of the cyl. and broke the groove where the slip ring goes. The other cyl pushed the back end out and broke the weld where the eyebolt plate attaches to the cyl wall. My questions for the group,,
1. I want to cut both cyls overall length by 1 1/2" on the packing gland end to do away with the slip ring /groove arrangement for the packing gland. I will machine 2 new packing gland plates out of 1 1/2" thick carbon steel and weld these to the cyl. The existing packing gland plates are cast iron and I don't have a way of welding these. I plan to keep wet towels on cyl and do skip welding to keep packing cool.
2. On the other cyl,, I will cut the busted back plate off and true up the cyl. and re-weld.
3. Both cyls. will wind up being exact same overall length. All new seals and rings to be installed.
4. Comments????????please,,,,,,,
