Resealing Hydraulic pistons and where to get seals 1960 John Deere Backhoe

[RolandJ]

I want to start re sealing a few of the pistons that are tired and It doesnt look that hard to do vs paying a fortune to do them. I just dont know how to go about finding the seal kits that are needed for the job. I fig some one here might be able to help me with this. Thanks so much.

I am sure JD still has them available or you can remove a set and compare them with a good hydraulic supply house. They should be able to match them.

It is not hard to do, at least in my part of the world.



A lot of welding shops have packing kits as they do cylinder repairs anyways.



John Deere may still have them available, also there are aftermarket suppliers as well.



The question is, do you want to have the packing kits on hand before you rebuild them or do you have the time to take the cylinders apart and search for the packings that way????



Do you have a big enough wrench or some other tool to take the cylinder end out???

I would rather find packing kits first. I still use machine every once and a while and I know soon as I take it apart I will need it. How can I fig out what kit it would need is there an aftermarket site?

I would start with a JD dealer for the seal repacking kit. You will need the cylinder group part number along with the machine model and serial number. The cylinder part number should be stamped or have a welded tag on the cylinder body somewhere. Provide this information to the dealer and he should be able to provide the correct seal kit parts for the cylinder group.

I know that some of the seal part numbers used on cylinder groups could date from the 50's or 60's.

You may want to have the dealer or cylinder shop rebuild the cylinder for you. After all these years I am sure the cylinder rod has some slight scoring of the chrome on it and the housing may need to be hone slightly. This honing and polishing along with the new cap seals and piston seals that will be replaced will provide years of service. Otherwise the new seals could leak and leak worst than before, because they could be cut by the rough surface of the cylinder rod.

Just a suggestion.

Loosen everything while the cylinder is still on the machine. When you get it apart, re-install the rod into one of the loader pins to loosen the piston retaining nuts. STP or OO grease is a handy assembly lube, espescially for lift cylinders where the packing wants to bind on the internal threads.
