1250 trans release lever

[smithth11]

Just got a 1250, and if anyone could provide a diagram or description of what the "release-drive" lever on the right side below the seat on this older model connects to I would appreciate it. I haven't been able to make it out on any on-line dragrams found so far, and with the rear covers off still can't figure out what's missing. That small lever shaft under the frame top cover is not connected to anything and the Cub stars & runs fine but the trans will not engage in either direction. Filled to the top of the rear differential plug with the HY trans fluid, it took the better part of 1 gallon, but still no movement. I can push this Cub so I assume either the trans is disengaged or it was already ruined. I'll be optimistic and change the filter just in case it's that simple. Thanks for any help on this.

First off Welcome to OCC!

Remove the tunnel cover and there should be a flapper attached to the release lever. It might be broke or missing altogether.
The release valves might be stuck down too which why it pushed easily but won't move on its own.

There is a medel flap that attaches directly around that lever held in by a roll pin 95% of the time that flap is broke off or missing all together. Look at the release valves on top of the pump there is two little numbson top one on each valve. If they are pushed down flush with the valve they are stuck. Try using a good penetrating oil and squirt the heck out of them for a.week or so. If they don't pop up then I would start look into a replacement or if you know somebody close by with good working valves just swap them out and see how that works

You may have a broken roll pin in one of the couplers on you're drive shaft, Check those also!

I agree with the other posters that there is probably a broken piece or two when it comes to the lever. Broken roll pins are common, and that charge pump valve release lever isn't one of IH's best engineering ideas.

I also agree, that with the transaxle low a gallon of HyTran, you could have some worn and/or sticky relief valves. If you don't find any broken roll pins, and you are unable to get the valve plungers to come up, you may need to replace or rebuild your valves. I would recommend against used valves. There is no reason to replace 35 plus year old valves with 35 plus year old valves, unless they have been rebuilt.

If you were to look on eBay under Cub Cadet, you will find a gentleman who rebuilds those Sunstrand pump valves. I haven't used the service, but I understand that he does pretty good work. New valves are available, but are very expensive. Were this me, I would give the rebuilt option a try.

Good luck with your project.

New Valves are in the neighborhood of $60.00 Ea.
Rebuild is about 1/2 that.

But you might be lucky and it is just a broken spirol pin as others mentioned.
Very rarely do the hydro's go bad.
