I hurt my JD 110 TLB Today

[CurlyDave]

I picked up a large 5' x 6' slab of 4" concrete today, intending to drop it on the ground and break it into manageable pieces, and it slipped out of the grip between the thumb and the backhoe bucket.

It dropped, almost balanced, and then fell against the extended rod of the outrigger hydraulic cylinder.

Oh, it broke into manageable pieces alright, but it also left a nick in the chrome plated rod, at about the half way point.

I cleaned it off with a scotchbrite pad and WD-40, five or 6 times, wiping with a clean paper towel between cleaning sessions.

It left a dent or a nick that I can feel with my fingernail, about half the size of a paper matchhead.

Questions:

1. What should I do about this? (Other than being more careful.) I can envision having to either get the cylinder rebuilt, or replaced.

2. If my labor is free, is it better to buy a new cylinder, a rebuild and send the old one back for a core refund, or to just get a mechanic to rebuild the existing one?

3. I am going to need the machine every day for the next two weeks or so, and then there will be a period of several weeks when I won't need it at all. Any guesses on whether the cylinder can last two weeks, being used 20-25 times per day?

4. Should I just buy a spare cylinder and keep it on hand for the day when this one goes, or can I get a fast rebuild in the SF Bay area, where I am using the backhoe to rebuild my burned out house.

5. When it goes, will I see leaking hydraulic fluid which gets worse and worse, or is it liable to be catastrophic?

6. Best place online to get a new or rebuild cylinder?

Sorry to hear about your problem, glad no one got hurt. You're gonna have to sell that damaged machine for scrap prices now.

on a serious note, if you smooth it as much as possible, and the only damage is a nick, I would expect minimal problems. I would use it and keep an eye on the oil level.

Assuming it isn't bent, I wouldn't think the nick is going to cause anything more than a small leak.

I have seen several on the out rigger like that. As long as seal is not getting cut, might not bother a thing.

I would polish it down with a good emery stone (fine grit knife sharpener )to remove any ridge that might be raised up from the nick and remove any sharp edged detents. It may leak a small amount of fluid as it passes that nick each time but it should be minimal. At worst case it will eventually eat out the seal and leaking will get worse to the point of needed a seal replaced. I dont see any catastropic failure in your future.

Great advice.

Dave, don't they sell armor plates for those outriggers? I have the armor on my 430 loader cylinders and it doesn't protect everything but it does help.

I had a knick in one of my FEL lifting cylinders on my original Kubota and I took it to work and they cleaned it and filled it with one of those metal putty sticks and then sanded and polished it down. I never had any trouble with it after that, I think I had that tractor for another four or five years before selling it.

4. Should I just buy a spare cylinder and keep it on hand for the day when this one goes, or can I get a fast rebuild in the SF Bay area, where I am using the backhoe to rebuild my burned out house.

As others have said, I would not be too concerned if you have a nick and
have removed the sharp edges. I have done that without a rebuild
before. You only get a tiny tiny bit of oil each time the indentation goes
past the seals. Check for a bent rod, of course.

If you decide you want the rod replaced and your tractor is down here,
take it to K, M & D Machine in Santa Clara. The owner (Ky) will make
a new rod for you, prob for less than $300 assembled. Less $ if you just
bring in the rod.

Good luck, Dave.
