I've been working on my 1655 in hopes of taking it to plow day this year. It's starting and running from the key now. Hydraulics work great and it moves although haven't actually been on it to drive. Just small forward and back in the shop.

Main question is about the pedal and linkage. My pedal is pretty much loose. Doesn't center itself. If I want this thing to stay in one place without having a foot holding it in neutral, I have to switch the range selector to neutral. I'm guessing I'm missing some kind of spring or something? Any thoughts?

After looking at the agco parts books online, I see there is a neutral return spring and an adjusting setup. I'm gonna head back out to the shop and see what I have. Although I see it on the diagram, can someone post a pic of the real deal. May be easier to tell what's missing or hopefully just misadjusted.

Hope this helps. None in the shop to take a pic for ya. Remove the tunnel cover and it's right there on the left hand side. Might be easier from the underside. Good luck.

It is probably the weird spring that's at the top left corner of the picture. I've had one fail through the years.

Is this something that can be obtained through an agco dealer? I haven't made it to the shop. Been reading through a couple more threads on here about the drive systems.

I have no idea, luckily I had a spare off a parts tractor. If it is this spring, 1450 up uses the same spring.

Well here are some pics I just took. There's nothing connecting the pedal to the speed control system on the other side. Not real sure what I'm missing here. I took some pics but they're pretty terrible.

Here's another pic from the top. I see all the springs intact and essentially functioning. Seems the pedal operates the direction lever on one side of the pump. The brake/neutral pedal on the opposite side also attaches into the side of the pump but does not seem to affect the travel pedal. These springs and neutral linkage are doing nothing. Could something be broke internally or is there some external linkage I'm missing here?

So, been reading some more. I'm guessing I have a busted internal roll pin. So, looks as if I'm getting into this pump. I've never worked on one of these internally. Hoping this won't be too tough of a repair. Now I'm wondering if I'll be able to take to plow day Friday. May have to concentrate on other things first to make sure the others are 100%. Any advice from the experienced here would be appreciated.

Eric

Yes, your internal roll pin has definitely sheared or moved out of place.

Well, as you can see the pump is out a disassembled. Need to upgrade my punches before I go any further. I don't want to booger anything up here. I know I've read people made their gasket but does anyone have a source for a set? I've done some googling, but haven't had much luck.

Well, new pin is installed. Since I haven't really come up with much on the gasket end, I plan to just make some. Does anyone know of thickness will matter? Seems the factory ones were pretty thin.

If you take a look at the article i wrote on rebuilding a sundstrand it will also have where to get the gaskets for the rebuild. While its apart get the plates lapped ;eat you have to tear it down again
