Hydraulic cylinders are a critical
Hydraulic cylinders are a critical component of farm equipment. They do lifting, tilting, swinging, splitting, digging, and a host of other tasks. If you own a tractor with a loader there are four that you can see easily on the outside of the tractor, two that lift the main boom of the loader and two that cause the bucket to tilt or curl. Many people use cylinders all the time and have no idea how they work. This video will show you.
Basically, a cylinder is what it sounds like, a long tube, with a ram, and inside that tube is a plunger and a lot of seals and wipers. You have a hydraulic pump on the tractor that makes oil flow, then the joystick, or loader control directs it to one end or the other of the cylinder. If the oil flows one way, the ram extends, if it flows the other way it returns, enabling you to use your loader, split logs, raise a brush hog, lift a round baler tailgate or dig holes with a backhoe. In fact, if you really look at a backhoe attachment, you may be surprised at how many hydraulic cylinders are on the machine.
My tractor has had a leaking cylinder ever since I bought it nearly five years ago. The leak was internal, no oil came out of the system, but if you left the loader and bucket up in the air, the bucket would gradually let gravity dump it, which could create a dangerous situation. The previous owner had purchased a seal kit to repair the problem but had never installed it. My tractor was due for some other maintenance items, the dealership had a Winter Service Special which offered me a discount for bringing it in when they were slow, so I broke down and had it repaired. I'd like to thank S & H Farm Supply at Rogersville, Missouri, the dealership I used to manage, for letting me film this activity in their shop. Their top technician, Hoot, disassembled the cylinder and let us look inside. In the next video I'll show you how he fixed it. There are tons of pieces and parts that have to be assembled, in the exact order, and with special tools, to get it repaired right. For 99% of my audience, myself included, I can tell you, DON'T TRY THIS AT HOME!!!
After watching Hoot install the seal kit I was extremely glad I had employed them to do this process, versus me trying it. There's a lot going on in there, and what we don't show in the video, is the massive amount of oil that spills when you break open a cylinder. Jobs like this one are why you need to have a good relationship with a dealer. Here's a link to the next video where the repair actually gets made: How to Repair a Hydraulic Cylinder.
