 Cylinder seal replacement

After getting my Kubota L3130 back from my brother in law I noticed some hydraulic fluid leaking out of the front seal on the bucket roll cylinder. He mentioned that he pulled some trees with a chain and showed my where the paint was worn off the top of the bucket from the chain hook.

I think he must have been hooking them up, backing up and giving the chain a good snap as it tightened. I'm assuming that this could put undue pressure on the seal.

First of all, is this most likely what blew the seal on the cylinder? Second, do I want to fix it myself or should I leave it to a pro? The older I get the less I want to do my own repairs. Smile I suppose the cost would be primarily labor.

No, if he did this I'm not going to say anything to him. Over the years I've been helped out many times by him and wouldn't have the heart.
Dave

 Cylinder seal replacement

Having been in the situation of repacking cylinders many times. Let some one else do it. Now that I am not working for a dealership I send ALL my cylinder work out. Even my own personal cylinders. I hate them all.

 Cylinder seal replacement

Short: I kinda doubt that, based on what you said about jerking it, really damaged it. Most likely it was ready to go before it was lent out. All it takes as piece or dirt or debris to get between the wiper and the rod and BINGO! (I screwed up and painted my cylinders on my backhoe and used masking tape to mask off the rods. Forgot to remove the tape and the tape got stuck in the seals. Before I realized what happened it was too late)

I used to be afraid of rebuilding my own cylinders until I took one apart and abot fell over when I realized how simple AND cheap it was to do it myself. Buy a cylinder seal rebuild kit from the dealer to be sure you have the latestand greatest parts. DOn't remove any seals until you lay them out in sequence according to the old ones already installed. It will take you longer to go get the parts than it will to replace one side. While doing it, think about all that money you'll save!

You should also be sure to have a low profile pan to catch the oil that might be left in the cylinder as well as be ready yourself with proper clothing as you are working in oil's home so have some lint free rags handy. The proper tools for disassembly will reduce the chance of failure in removal of the end caps.

Short,

Since this brother in law is a good one, give it a little while (so he will not think you think he caused it) and invite him over to help. Just in case you think he may have caused it, give him the oily end. Laughing out loud

Thanks for the responses. I'm glad you think it was caused by something other than my BIL. He's not the type to abuse anything. I'll take a look at it to see if I want to try it but most likely I'll take if off the loader and give it to someone else.

Dave, I didn't say he might not have caused it! Sorry, but things happen and if this is the worst then all is well. I didn't get to see where the chain was attached. It could be a freak we really don't know but a ten minute removal and a trip to the dealer could be an clean and easy out. Lack of knowledge of the proper operation of a piece of equipment is the most common cause for uncommon or unscheduled repairs.

Now that I've gotten a few responses, I don't think he did it either. The seal is just dripping a bit, not spraying like a completely blown seal. It's something I'll have to fix this summer. We've got a heavy equipment repair business just a mile down the road and they should be able to fix it pretty quickly if I remove it.

I've replaced seal in cylinders sevweral times in the past. It's really not that difficult on easy to handle size like on a CUT loader, the bigger long stroke ones like on big backhoes are just plain heavy and clumbsy to handle, those are best left to the pro's. Count on it being kinda of a mess, you never seem to get quite all the fluid out no matter how you drain them prior to repair. Frank.

Dave, if you do it yourself, Use brass rods to pull out the
old seals and maybe help in installing the new ones. I worked on Hyd' in Air Force and it kept us from scarring
the rods. We used brass welding rods and made hooks and spoons with them.
