This is making me crazy! Either my Cub is haunted, or I screwed up somehow when I rebuilt my Touch Control. The Touch Control on my 51 Cub has been acting in a strange way ever since I rebuilt it 2 years ago. I put an IH rebuild kit in, and as far as I know everything went according to the instructions. It had worked fine before - I only decided to rebuild it because when I removed the Touch Control unit to clean off grease and paint, the control piston shaft accidently came out and I could not get it back in. It was pretty clean inside - the screen was in good shape and had a little dirt, but that"s all. I also put a seal kit in the hydraulics pump because I had found the pump’s retaining nut in the oil pan, and had to remove the pump anyway to put the nut back on it’s shaft. But what I’m concerned about is as follows: 1. When I move the control lever to pull the power shaft in, the last inch of stroke labors and makes a metallic "creaking" noise, almost like a dry o-ring rubbing against a cylinder metal wall. 2. When the tractor is running, every minute or so you’ll hear the hydraulics unit move ever so slightly, all on it’s own for just a split second, making a metallic "chirping" noise like a hiccup. At the same instant the motor RPM will dip, and then return to normal. It’s almost like there’s an air pocket that circulates thru the hydraulics. The fluid level is fine. I was careful to lubricate the o-rings with trans fluid before I put them in. And I’ve probably stroked the control lever hundreds of times to hopefully work out any possible air. The hydraulics works - but it’s sure annoying. Has anyone ever experienced anything like this? Is there some adjustment I forgot? Any ideas or suggestions? I’d sure hate to pull the Touch Control apart again, especially when I don’t even know what to look for, so I guess I"ll live with it till something breaks. But I hate listening to it!
