I have a LA481 with a leaky lift cylinder and am thinking about putting in the seal kit myself if I can figure out how to get it apart. I know the end unscrews but don't know the method. I had the cylinder on the other side done a few years ago at a shop, and the end cap didn't get chewed up in the process. In other words, I don't think they put a 4-foot pipe wrench on it. Maybe it comes loose easily, I don't know - haven't tried yet. Haven't been able to find any videos specific to Kubota cylinders, just generic stuff. Is there a tool that fits the 2 holes on the side of the cap and it it needed? Thanks.

Not familiar with your loader, but there are lots of different schemes for those cylinder caps. My B219 FEL used snap rings to hold the caps. My B670 backhoe cylinder caps unscrewed with a wrench I made like this:

With out seeing it .... It sounds like a hook spanner with pin is needed if the holes are on the side of the cap or a pin wrench like lilfoots picture if they are on the end... As well as a strap wrench to hold the cylinder...

Others will know for sure

Aluthin, I think the hook spanner is the right tool, thanks for the tip. I don't have one so time to go web shopping. Pin hole size is between 3/16" and 13/64". Looking at hook spanners online and they don't specify pin size so I'm hoping that's somewhat standard.

Here's what I have:

Thanks, Bill. Adjustable seems like a good idea. I grabbed one of these of Ebay for $26 including shipping. It oughta do the job, my cylinders (lift and dump) are just over 2-inch and this tool has a range of 1-1/4" to 3" with a 3/16" pin. Overall length of all the brands I looked at was about 8-inches ... it will be a pleasant surprise if I don't have to slip a cheater bar on it.

Yup, I have a lot of machine shop equipment/fixturing type stuff of various sizes that use pin or hook type engagement. Works out great for me, the tools cross over to tractor & motorcycle stuff nicely.

Better leave it bolted to tractor to loosen it. Is bloody tight. I made a wrench,think it was a piece of heavy plate and a couple of hard pins. Four foot pipe to break it loose.

I decided to punt and took the cylinder to the shop that did my others. This time of year I need the up-time and it's dicey whether I could turn it around as fast as needed. Last time they charged be 20 bucks for the labor - not bad. Maybe next time. I'd like to have a cylinder to practice on but all I can find is new and don't feel like dropping $650 just to satisfy my curiosity.
