HYDRAULIC CYLINDER R&R

Before we go too far(brand/application)  into this .....is there another  thread previously that has addressed the basics?? If not, then I'll be more specific.....late

I briefly discussed it with a Craftsman Jack.  I don't think we went into basics though, I already have experience with that from my heavy equipment days so I was more looking for parts sources.

It is pretty simple.

I'm looking at the 300X front end loader on my JD4410 compact utility tractor. I was quoted approximately $175.00 a cylinder to reseal(with me bringing them to the shop). That being said, I researched  JD seals for all four cylinders....parts alone, no sales tax came to $220.50.  I then briefly did a Ytube touch 'n go to see how difficult this really is. Other than hyd fluid being everywhere , the only tool I lack is the curved pic thingy  and a brass punch.  Do most of these cylinders have snap rings to hold things in place or is a spanner wrench the tool of the day?

Any and all thoughts are much appreciated ...cuz I got the time ,most of the tools, just not thrilled  spending $400.00 plus on labor.....go     

Generally you have a big ass nut on the end that the piston comes out of, once you remove that it is usually just snap rings.  If there is a valve body attached to the cylinder, you can get into more esoteric tools, but those are usually just torx bits or allen keys.  Like I said above, they really are simple things. 

The only thing you might be able to mess up is there are one or two kind of expansion rings.  When pressure is behind them they expand to help seal, and when pressure is in front of them they fall down to allow the piston to retract by gravity (assuming it is a single acting cylinder)

There should be an exploded view of the cylinder online somewhere that tells where everything goes, you can check that for what holds it together, but it should be just snap rings internally.

Abom79's Youtube channel has a few videos on hydraulic cylinder repair.
