Cub touch control cylinder

Could somebody help me out on how to get these parts pictured apart? Manual says to "remove yoke nut and remove piston from yoke". The nut is off as you can see but this thing does NOT budge. Pictures are pretty clear...the red thing comes out of the shiny thing, to be technical. If someone knows some method to do it...love to hear it. Otherwise I sleep on it and hit it hard in the AM. Appreciate any knowledge you would like to share!

IF, as it sounds, she's good and stuck you might try judicious use of a drift and hammer.

Were it mine and it was time for a hammer, I'd stand it up in a vise, with the yoke end of the piston resting on top of the jaws, and the yoke dangling below. It will need to be a loose fit, as close as you can get without the vise holding the yoke tightly. Then proceed to beating on the threaded end, with either a drift (of smaller diameter) or chunk of hardwood so as to avoid damaging your thread.

If that doesn' t do it, you might also try a variant of the trick of first giving a short tightening twist to a stuck bolt to help loosen it. Drill a hole in your bench or a pice of hardwood you can set on the bench. ?The hole should be large neough to accommodate the thread. Stand the whole affair up so that you've supported the inner end of the piton, and apply a few healthy raps tothe end of teh yoke, then proceed with step 1, trying to drive it back out.

If it's bound by rust and crud, it is far more likely to have worked its way in from the yoke end, so a thorough application of your favorite penetrant from that end might also be helpful.

I've had those pistons/rods out or two tractors and don't remember having to separate those parts, so why do you want to take it apart other than having everything squeaky clean? But, I may have forgotten something. I currently have the reservoir of my Super A disassembled -- will look at the rods later.

Well, I have never kept a secret what I though of my own natural mechanical ability and I won't try to wow you with it now. The manual says to take it apart. That is all I know.

I do see an "O" ring in the picture in the manual and I ahve a complete rebuild kit so I probably have a replacement to install there. Also, when I took the cover off the reservoir the large oil strainer was shattered and in pieces all over the inside. I suspect some crud has made it's way to the nether regions of the unit and I am trying to be diligent in cleaning all parts. My goal here beyond cleaning is NOT to have to take it apart again. It's heavy, oily, and 20 degrees out there. If you get a chance to look at yours later and have some ideas I would sure be grateful to hear them! Thanks, as usual, for your help!

Well she be loose! I stood her up in the vice, only varying the advice by putting a heavy cloth in the vice first to cushion the edge of the cylinder. Several light taps yesterday with a smallish peen hammer did no good so I got a block of wood and pulled out a bigger hammer. After shattering several blocks of wood I abandoned that idear and exchanged the larger hammer for a blacksmith hammer. Three nice taps and one almighty wack seemed to do nothing but the next time I tapped it the threads disappeared inside the cylinder. It will, however, only come halfway out so currently it is soaking in some PB Blaster while I tend to such trivialities as making a few $$$ so I can afford to be a Cub owner. Appreciate the help, I'll let you know later how it goes!

It is widely known locally that I am the owner of an impressive collection of hammers. Some say that if you put them all in a sack that I am almost as....but that is another story...

It's apart! Heavy corrosion on connecting rod yoke and frozen at the pin. Loose now but will need a good cleaning before re-assembly.

CNKS does make a good point. NOt sure of any reason to take them apart on a rebuild, unless, the yoke had somehow been bent under a strain and needed to be replaced. The leerage on that setup is so that not much loss of length on the piston and yoke can cost you quite a lot of travel on the business end.

Yours looks to be straight, but we share a trait (Is that poetic, or what?), and I'd probably do just like you are and take it apart just because I could and would be cleaning it up in the process, so that they guy who is working on it in ANOTHER 50 yrs wont have 100 years of corrosive bonding to overcome.

Sounds like you're on top of it and she'll come free so you can clean it up with a ScotchBrite, but if she just absolutely ain't gonna, refuses, won't come apart, I'd drive it back together and thread it home. for reassembly

Oh, and ping.

Figgers. You were working while I was typing.

Pretty work!

Forgot that I have them back in the reservoir. Mine were loose, not corroded like yours, tractor has been used every summer month or so for a couple of hours each time for about 10 years. So, my opinion was "if it ain't broke, don't fix it". Did not see a reason to disassemble.
