TC control valve pin won't budge

Postby Clubless » Tue Jul 19, 2016 8:36 pm

I have leak around the TC control valve, so I started work to replace control valve O-ring. I have the hydraulic block removed from tractor and on the work bench (tailgate of truck). I removed the cotter pin and set screw from the control valve pin, but the control valve pin will not budge. I sprayed some PB blaster on it late this afternoon in hopes that will free it up and I will then be able to slide it out. I assume it has rusted itself tight. Or, is there something else that would cause this problem? I used a couple of screw drivers to put some pressure on the pin, but pin didn't move at all.

If the PB blaster does not work, my plan for tomorrow is to remove the operating lever and I should be able to remove the control valve with attached the operating lever.

Anyone else had this problem? Any suggestions?

Thanks,
Gary

Is that after removing the operating control lever?

The slightest bit of torque on the pin will make it had to extract.

Happy to say that I was successful in removing the control valve pin and replacing the O-ring. PB blaster did not free it up, so I removed the control lever and rockshaft and pulled control valve out. One good hit with the punch and the pin jumped down on the floor. I ran a drill bit through the lever holes so pin would move in and out freely. Got it all back together and ready to mount hydraulic block back on tractor later this evening when its a little cooler.

Now on to the gas tank project of cleaning and Red-Kote lining. I'm thinking I might do this myself. My local radiator shop quoted me a price of $165-$185. I've been reading a number of post here on "How To" clean and line the gas tank. Any suggested post that I should be close attention to?

Thanks,
Gary
