45 Loader on an A

We just put a 45 Loader on my 1948 A. It goes up and down fine and doesn't settle at all. The problem is, is that it has NO lifting power at all. It will pick up 150 lbs pretty easy, but anything more than that it won't lift. We made sure to get all of the air out of the lines, so that isn't the problem. Any ideas what is wrong? Is it something with the Power-Trol in the tractor, or something with the loader itself? Any help would really be appreciated! Thanks

Even with high pressure cylinders, it should still pick up more then 150#. Cylinder dia, the face of the piston on the low pressure cylinders when mounted on the 2 bangers was 3". The high pressure cylinders used when mounted on the 3010 was 2 1/4' DIA. The 45 loader was rated for a 3000# brakeaway and a 2750# lift to full hight. So even with the smaller dia lift cylinders that were for the 3010, it still should lift 1000# or so. First thing I would do is to put a pressure gage on the remote hyd outlets and check the pump pressure. Been a long time since I did anything with a "A" so I don't know if and how the pressure relive valve is ajusted. Could be a stuck relive valve. Maybe someone else could help here. Or get a shop manuel. Then I would have the tracors hyd pupm rebuilt. A good machine shop can shave the faces and the gears and bring it back to new.

After thought,,, It's possible that it has the cylinders for the 3010, but would be dougthful if the mounting brackes are stock factory for the 2 banger. If it had the high pressure 3010 cylinders, the mountints would most likey also be for a 3010, and would have to be modified to fit a two banger. The two banger stock factory brackets would also have to be modified to fit a 3010.

Mike:

That's what I was talking about when I mentioned high pressure cylinders. After nearly 50 years, there's no telling what mounts are with what, or how many loaders were used to put one together.

Right. We have a 35 loader on a 630. The 35 loader was never built for the 630. The loader came off a 2010. As it is now, it will never fit a 2010. A onther possible would be bad packing in one of the cylinders. It could be bad enought the when raised and left over night it will seddle back to the ground. Or it could also be that when under pressure when under trying to pick up a load it then blows by the packing. A hyd gage test gage on the remotes will pin point the problem to the loader or the tractor.

Mike:

If it were blowing by that badly, it should never "kickout" the Powr-Trol lever at the top of the cycle. You know, it could be just low on oil.

Jericho:

Does it happen to have the high pressure cylinders on it? If so, there's not enough surface area for the 1100 psi pump to lift much. Sorry I don't have the diameter for the high pressure cylinders, but they're noticeably smaller that the low pressure ones appropriate for your 'A'.

Frank,
I am not sure if it has the high-pressure cylinders or not. If I remember right, they are maybe 7/8"-1" diameter. I could be way off though. I know that the loader used to be on a '51 B. What would I have to do (to the tractor) to make this loader work if this IS the problem? Thanks.

Jericho:

First:

Did it work correctly on the 'B'. That tractor has the same pressure as your 'A', so if it worked on the 'B', we need to look elsewhere for your problem.

Second:

If it had low pressure cylinders on it, two ways to fix it: change the cylinders to larger diameter, or install a pto or governor driven pump that would operate at the necessary high pressure.

Now, after looking in my 45 loader parts manual, it looks like there are two ways to tell a high pressure cylinder from a low pressure one. The low pressure one is around 2 to 2 1/2" diameter. The high pressure type is 3 1/2" or so, and it uses three tie bolts the length of the body.

I think I have the low-pressure cylinders. I know that the outside diameter is fairly small...2 - 2 1/2" seems about right. The inner-cylinder diameter was about 1". It hasn't been on the B in about 2-3 years. However, last time it was on there, it worked fine.

My tractor is at my friend's farm, about 60 miles from here, so I can't just run out and look at it. I am just trying to get some ideas so we can troubleshoot it more when I go back down there.

Thanks.

If you say the outrside diameter is fairly small, that's the size of the high pressure cylinder. Look for the tie rods. With=high, none=low.
