Farmhand F25 Loader Question

zlarryd · Feb 23, 2023

I pulled out the high lift pistons of the loader to replace the seals. One piston has been replaced with a matching pipe and has a modified end cup at the seal end that slides onto the pipe end and the seal bolts to the end of this piece. The piece is loose on the pipe and appears to have a pin that is driven thru holes cut in the pipe walls and may have a wedge pin of sorts for attaching the end piece to the pipe. A pin is shown flush to the pipe outside face on one side but the pin is missing on the other side of the pipe, and the piece is very loose. See the attached picture. Does anyone know about this piece and if I am correct in that a wedge pin is used to hold it in place? Is the pin a single long pin or two pins, one for each side? Any idea on availability of a replacement? Hopefully the photo will load!

I would guess the seal on the end of the cylinder is just a dust and dirt seal. If that cap is carrying a seal that is holding the pressure that is acting on the ram those two dowels do not look like a strong enough retaining system to hold that piece in place under that kind of load. The other end of the ram inside the tube would have a packing style piston which the pressure acts against. Unless I am not understanding exactly what you are saying. Is the ram still in the cylinder we just cannot see it in the photo? You ask if the pin could be one long pin or two, as in one for each side. If you think about it if the ram slides in there for it to be one piece pin the ram would have to have a continuous slot in it the entire length of it. Probably would not work to good.

The FARMHAND parts books are on the ACGO site.

Here is the address to the book for the F25. You will need to copy and paste it into your browser search as trying to link it is blocking this post.

Here is the picture of the lift cylinder in the parts book. It looks like it only uses one pin (item key # 6) at that location.

Ya, it's just a single pin. Drive it in the get the seal holder off. Drive it on through and reuse it. Pic looks just like I remember but it's been a long time since I've rebuilt one.

Thanks for confirming that. I have a round hole on the other side of the pipe but no
pin there. Due to I think wear the end piece has a lot of play in it. Do you recall
if there should be a pin on each side of the pipe? I am concerned that extra play my
cause the end price to maybe turn a little if the load on the sweep bounces, as there
look to be scratches on the sides of the cap.

Thanks for the information! Hopefully Agco still carries parts. My pin looks to be a
bit worn and I wouldn't mind replacing the end cap too since it looks scratched and
seems too loose. Better to try to replace now and not wait to see what may happens
when I'm bringing in bales.

One pin per the book and Nebraska Cowman's post.

Scratches are likely from foreign material (dirt, etc.) getting passed the felt packings in the sleeve at the open end of the barrel, then ending up between the piston and barrel bore.

The picture is of the end of the inner cylinder pipe. I took off the rubber end seal before I took the picture. The end piece has a smaller diameter pipe attached to it that fits inside the pipe you see and keeps the end piece lined up with the cylinder pipe wall. The drive in pin is just there to hold the end piece on.

The end piece (#7) is called the piston and is held into the piston rod weldment (#1), which you are calling the inner pipe, by the pin (#6). The piston should have a cup (#eight) and spring (#9) held on by flat washer (#10), lock washer (#4), and capscrew (#11). The names of the pieces and part numbers are on the parts book page I gave you the address to.

Thanks, I was just looking on Agco's site at them. I already picked up new seals here in town at Baum Hydraulics, and the old basket looks fine.

The Agco site says I have to call to check on availability of the end piece (#7) but the groove pin is in stock near me.

I'm going to run down to the shed and take out the groove pin and check over the end piece and then call Agco for parts today.
