Help!! What a mess

Today I am having hydraulic problems! What a mess.

1. Original pump (the one that came on the tractor when I bought it in 96) cracked and spewed fluid on my shoes whenever you used the touch controls
2. Obtain old pump from IH "C", installed, worked great except the fluid kept disappearing
3. Found missing fluid, was in the crankcase, seems the pump had a worn out oil seal and let fluid past the seal into the motor
4. replaced seal, seems the system runs warmer that I remembered, blew gasket at the touch control after about 2 hours use, assumed that all that loosening and tightening damaged the gasket.
5 Bought a new gasket, cleaned the touch control box of the old gasket, installed new, cranked tractor, let idle for about 5 minutes at low rpm, worked touch control a few times to ensure that fluid was flowing and walked away to hook a chain around a hay roll, gasket blew in same place. WHAT A MESS!
6. Took steel pipe off of the tractor, seems to be hot to the touch, removed blown gasket. Gasket blew at the small hole on the touch control, that is Moe (5/8 inch), Larry (3/8 inch) Curly (1/8 inch). I don't know much about the hydraulic cylinder but I asked my old neighbor (has a lot of IH equipment) about this and he suggested that the pump from the "C" was to powerful. This is plausible since for the first month or so I used the pump it was not delivering full pressure, now it is. I thought that maybe some trash might have gotten into "Curly" and plug the hole, thus the heat, but I guess higher pressure will cause that too. I have my original pump here today and I would like you to check them against your pump and let me know what you find. I can get a replacement pump ($$$) if that is the culprit, I am not ready to get a new touch control unit. can this be rebuilt if its plugged, can it be backwashed with fluid somehow to clean it out.
Crank you tractor up and let it idle for a few minutes, use the touch control some, let me know how hot the pump and lines are after 10-15 minutes? This should help me some, Have you ever heard of this? Any suggestions?

Pump numbers (hard to read) but here goes

3608688R92 ( the other pump was made by Cessna, ironically the dealer I got the seal, gasket from said it was listed as a pump for the 140, don't have the part number with me)

thanks
