Mine looks like that... I bought this used off our local NH dealer I suspect no one has ever been up here since it was new... I can't put it all back together till I get the cork tape coming in the mail.
Thanks for your reply Harry. I didn't change anything yet till I find out what I needed to order. This is about week 3 of me doing all this. The tractor had a/c two years ago but developed a very slow leak. I can't locate it and I am not sure if it still exists since it holds pressure now...
ok here is what I got:
static 135 low and 140 high
after start 50 low and 250 high
this was with an ambient temperture of 95 in the sun
temperatures to touch:
- Drier both sides hot to touch
- Condenser Warm in and hot out
- compressor Hot on high side and cold on low side
- between...
Wow Lou Thank you! I will get to this in the next day or two and report back... I am feeling a bit under the weather. I am determined to get this right.

Again with...

My reply: What could the problem be? When I...
Thanks again Lou! I have that chart as well. I read that if looking for a restriction/obstruction you can actually feel the piping of your system and follow the temps and drops in temps for possible blockage. I am yet uncertain if I even have a blockage. I just came in because it was so hot...
2nd update!!!
I put freon in and touching the evaporator I had cold going in to touch and warm to touch coming out. Both sides of the drier were hot to touch and both sides of the condensor were hot to touch. guages showed 300 on the high side and 75 on the low side after freon. The static...
UPDATE So I read in one of the shop manuals I have for this tractor, that the expansion valve is located in the ceiling. LOL so I took the ceiling down and found all of my dye lying in a puddle of dirt. Today I am going to clean everything and attempt to pressurize the system and see if I get...
