touch control rebuild questions

HI there,
I am rebuilding the touch control on my super c and are having a few issues. I have an I&T service manual was looking at the exploded view of the touch control unit and it is showing o-rings/seals where I did not have seals when it came apart. Did the units vary a little bit or did those seals disentigrate and disappear in the past 58 years.
the numbers on the side of the unit were 354352 and below that 322w. Any help is greatly appreciated. I do not want to take it apart again as it is getting chilly out to work :)
Thanks
chris
 
Chris,

There are (at Least) two variations of the touch control block used on the Super Cs. The serial number split was at 191866, but someone may have replaced the hydraulic block in the past 50 years.

The parts book has the best pictures and there is a Serviceman's Handbook GSS-1024 (binderbooksdotcom) that covers rebuilding the touchcontrol. There was also a lot of discussion this spring as about 3 or 4 of us were rebuilding the blocks at the same time. Try searching the archives for those discussions.

thank you. I just wanted to make sure before I put it back together. I will have another scan of the archives to see if there was anything I missed

(Hey Greg! How ya doing?)

TMI, a couple of pics from my SA, which had a Pesco pump, if yours is similar to mine. The arrow is pointing to the part of the body that contains the O-ring or seal (some had one, some had the other) that keeps the hydraulic fluid from escaping forward into the engine.

In the second pic, the shaft with the arrow goes through the front part of the body, and the important 0-ring-or-seal sits around this shaft. and is within the bore in the body.

I had to scrape paint to find the numbers on the pump, but IH has a rebuild-kit (you can see part of it to the left) and they are specific to certain pumps.
Let me know if you have other questions.
