Another loader question, 3000/4600SU

I have a '66 3000. I've found a loader that's currently on a 4600SU that I'm going to look at tomorrow. I found a loader on eBay that looks just like it that says it's a 19-557. I can't find anything searching for a 19-557. The owner just bought the tractor with the loader on it and doesn't need the loader, so he doesn't know a lot about it. He said that it was originally set up with a crank driven pump but it's gone and it works off the on-board hydraulics. At least the left arm has been repaired, you can see it in the pic. I can't tell if the lift cylinders are 1-way or 2-way.

From what I find this should mount right up on my 3000. Do you think it would function ok hooked into the hydraulics on my 3000 or am I going to have to find a pump? Any info you can give me would help if anyone knows anything about it. I'll know more after I look at it.

In VERY basic terms a 4XXX SU is 3000 series from transmission forward, and 4000 series from trans back, so the front mount should be OK, but you may (repeat may) have to make changes to the axle attachment points.
 
looks to be a 730 loader! You may have to do something with the rear mounts, as mentioned, but they may already be set up to bolt to either rear axle, as those loaders were common for both tractors. As to hydraulics, the tractor hydraulics will provide all the lift you need, but will be sloooow! The lift cylinders are double action, so you will have down pressure.

Thanks for the help, fellows. After looking at the only other pic he posted, both arms have been repaired. Looks like they've welded a length of angle iron on them. Should I be worried about this?

looks to be a neat professional repair, so I wouldn't be too concerned! That being said, I would be thinking that you won't want to be working that loader to ultimate capacity, as the weak point will be the front axle of your 3000, as has been discussed here many times.
 
Yeah, we just want it for pretty light work. Pushing limbs into a pile, pushing some snow out of the drive, moving things around that we'd rather not lift into a truck, that sort of thing.

Any practical way to strengthen the front axle?

Another thing I've been wondering, that lift is pretty heavy. I know we'll need to be more careful on a hillside, but as long as I have an empty bucket as low as possible, how much more likely is it to try to tip over than it is without the loader when mowing on a pretty mild hillside?
 
My first response is check out the front end difference on the two tractors. I bought a scrap quality 4000 4 cyl once that came with a FEL. The front
axle was reversed (upside down) and showing was a weld where some PO overloaded it and broke it. To each his own but"I" wouldn't put a loader on a
3000 or less.

Other thing is do you have power steering? What size are your front tires? You can drive it off your main hyd pump tapping into the access under the
front of your seat so you don't need frontal pump access. The two cylinders are 2 way as verified by the two hoses coming over to the cylinder shown.
 
I went and looked at it this morning. The data plate says it's a 19-528. I saw no signs of cylinders leaking. It does look like the hoses/valve have/are leaking. It also looks as though it was made to fit a shorter tractor. Hopefully I can just cut off their mods and it will mount right up.

Well, I bought it. Now more questions.

The crank driven pump is not there. They had it plumbed into the hydraulics on the tractor. They used one of the QD remote hoses for the pressure side and dumped the return into the top of the rear axle housing.

I don't have a similar port to dump the return into, so I just figured I'd plumb mine directly into the valve where my remote hoses are. Anyone have a better idea? Also, I can't ID my valve. There are four different valves listed in my SM but not this one. Which hose is pressure? Front or rear?
