Furguson Hydraulic question

Hey all, Im a new poster here but long time lurker. Im not the best with computers so please bear with me..
Im working on Grandpas old Ferguson TE20 (I think) for my father in-law. Grandpa recently passed away. I dont know much about old tractors. I grew up in a trucking family and carried on that tradition. The wifes side are the farmers! :)

Anyway, the old fergie starts and runs great! But the issues lie with the load. She has a Allied loader bucket. Wont go up/down or tilt. No hyd psi at all.. (full of oil) Grandpa always said the keyway would slip out on the shaft in the pump. So, that's where I want to start. Ive had similar issues with the pto-pump on my truck..
The pump on the tractor is just below the grill on the front of the tractor... How is it you guys take these off? I see a bolt in each corner but I cant budge them.. Any pointers fellas?

Thank you so much.
If I can figure out how to post, I took a couple pics... I think I posted in the right area this time...

 
First thing is to determine if the pump is turning.

Be absolutely sure the lift can't fall, block it or chain it up before you get under there!!!

Start it up and look directly behind the pump and see if the pump is turning. If it is, have an assistant pull back the raise lever, see if it stops under load. If it does, the key has fallen out or has sheared. Also, look to see where the coupling is turning, where the shaft is not so you know what and where to go in after.

If the pump is turning under load, the problem is likely the pump is starved for oil, a valve is not centering, it's plumbed incorrectly, or the relief valve is stuck open. Possibly the pump, but not likely.

It appears from what I see of the mount that the welded plate only keeps the pump housing from turning, like the 4 bolts just extend through the holes... But look behind the pump, see if possibly it's double nutted, can't really see from the picture. Possibly the only thing holding the pump on is the shaft. That is not unusual, that keeps the pump from binding if everything is not aligned perfectly (and they never are).

If nothing appears to be holding the pump housing, look for set screws in the coupling, there could be more than one. Try prying the pump off the coupling. It may have cut grooves on the inside if it's been spinning, could be somewhat difficult but it should come off.

Again, this is a lot of guessing and assumptions, can't really see what's going on. All of this is aftermarket, nothing directly related to Ferguson. Be careful, don't break anything because of what I suggested! LOL

And don't get hurt!
 
Thank you for the reply!! I ended up getting the pump off. It was just like you said, the bolts extended through the plate. Took all of yesterday to get the bugger off though...

I knew going into this the pump was working fine, and it still is. My assumptions were correct it was somewhat what grandpa had said before he passed. The "key way" slipped out. But there is no key way really. It looks like there is like a cross pin though the end of the shaft that engages the pump. But said pin has worn down to nothing so the shaft was just spinning inside of the pump connection.. Ill post a pic of the pump end. Shes pretty beat up...

Now, to try and figure out how to get this shaft out of the tractor so i can put a new pin in... Seem like it goes through a bearing then bolts to the bottom pulley of the motor...? Sound right?
Any ideas how to take said shaft out?

Thanks.
Heres a pic of the pump. Slips over the shaft then cross pin the the shaft lines up.
 
Sorry for making a bump in the thread guys. This ol girl took a backseat in the project list unfortunatly. Between work and a tornado going through the farm not much spare time.

I was just looking for more info, i guess I forgot where I left off. I think my next step is taking out the shaft that runs the pump off the front of the motor.... I assume to get the sheet metal off I need to remove the hole bucket assembly huh? Does anyone have a pump on the front of the motor they would know the routine for the shaft removal?

Thanks again
 
All you need is a way to attach that shaft to the front PTO, and there's plenty of ways to do it. Mine has a flange bolted to the pump, and flange bolted to the rod out the front pto. They couple with 2 bolts.

Looking at yours the keyway is broken. Can you get that shaft off the pump somehow? Maybe bolt something else on?

This is what mine looks like, might give you some ideas.

Thank you. I was planning a flange of some sort I just wish the shaft came through as far as yours. Mine is still inside the front of the tractor 4".... Thank you for the picture!

I dont think i can get the shaft off the pump. grandpa (before he passed) through out the years must have had some of the same issues. Welded more times than i can count lol
 
My shaft doesn't come out that far either, that's an extension on the actual shaft, 12" or so. It's actually not even solid steel. I'm sure you could figure some way, especially if it's a keyed shaft, to rig up something that connects to your pump, hten slide it over the shaft coming out of ht eengine,a nd mount the pump a little further out.
