John deere 70a loader cylinder rebuild kit

John Deere manufactures personal lawn appliances as well as commercial-quality outdoor and farm equipment. Many John Deere machines use moving parts that are controlled by actuators, or hydraulic cylinders.

Rebuilding these cylinders entails completely disassembling the cylinder and resealing every component with new seals. Exact rebuild instructions will vary according to each particular cylinder.

Each cylinder also has its own unique seal kit with every seal that needs to be replaced during cylinder overhaul.

Lift the lock ring out of its slot with a screwdriver, then rotate the rod end guide with a spanner wrench until it faces the same direction as the end of the lock ring. Pull the lock ring out of its slot. Skip this step if the cylinder secures with a snap ring. Remove the external snap ring with snap ring pliers, and drive the rod guide into the cylinder past the snap ring groove with a wooden dowel.

Clean any debris from the snap ring groove, and install the filler ring from the cylinder seal kit into the groove. Remove all the seals and rings from the piston and the rod guide. Remove and discard the filler ring from the snap ring groove.

Inspect the piston, rod guide, piston rod and inside of the cylinder for nicks and scratches. Smooth any rough areas with an emery cloth, and replace any parts with deep gouges. Install new seals onto the piston. Different cylinders may have different seal configurations, so install the new seals in the same configuration as the old seals were installed. The cap seal will probably be the last seal to install on any John Deere cylinder piston.

If the cap seal is stiff and difficult to install, soak the cap seal in hot water for five minutes to make it more flexible. Then install it the seal quickly. Tighten a hose clamp around the piston to shrink the cap seal if it is loose or if it will turn on the piston. Protect the seal by placing a shim between the screw portion of the clamp and the cap seal.

Waiting eight hours after installing the cap seal onto the piston will also allow the piston to shrink. Place the rod end back into a soft-jawed vice and install the external snap ring, rod guide, piston and nut. Lock wire-type cylinders do not use an external snap ring. Tighten the piston nut to its specified torque. Tighten a hose clamp around the rod guide's internal snap ring, and then loosen it a little.

Insert the rod into the cylinder until the internal snap ring is secure. Pull the rod outward to ensure that the snap-ring is engaged. Install the external snap ring with snap ring pliers, or install the wire lock ring by inserting it into the lock ring hole and turning the rod guide until the lock ring is seated.

Use the cylinder's illustrated parts breakdown to see just how components fit together.

I took the part off the piston to measure but am not sure which way it goes back on. In the picture, it is the large part closest to the nut on the end of the piston, has the yellow plastic ring around it.

I would assume the beveled end would go toward the nut to make it easier to place inside the barrel. Stupid me didn't pay close enough attention to it or take a picture before I removed it. Anyone have a picture not parts diagram because it is not a clear picture of the inside of the cylinder? Also, would anyone happen to have an owner's manual for the 70A loader or know where I can find one? Thanks in advance. Last edited by Enimo; at PM.

It is showing four hydraulic cylinders for each style of hydro cylinder. Four for the cylinder with the circlip and four for the cylinder without the circlip. Both the bucket and the lift cylinders show the same seal rebuild kit part numbers.

Not surprising. My cylinder is one without the circlip. That leaves me four choices by the looks of it. Each of the four kits is priced differently but when looking at the the diagrams they appear to contain the same parts.

What I would like to determine is which of the four available seal kits do I need. Anybody been through this process already and willing to share what you have learned? Thanks, Mark.

I think I have narrowed down the kit I need but I am now planning to purchase it from a local dealer as opposed to mail order.

By ordering through the dealer I am hoping to get the correct kit. I will try to do the install myself. Others have stated it can be a job getting the big end unthreaded. I have not yet found a thread describing a method for loosening the big end. I am thinking pipe wrench and long pipe for leverage. Any thoughts on this method?Most tipping services are based on anecdotal evidence and have a lack of reliable results to show for it.
