South Georgia | Hey, Kel,
I don't remember what the static pressures were, but they agreed with the Fahrenheit temperature scale on my set of gauges. Ambient temperature today was around 95 when I started working on it.
I didn't let it run for a full hour, but I did let it run a half an hour or longer, and the pressures really didn't change from where they started when I first cranked the engine.
TX valve...? You mean the expansion valve? The pressures never fluctuated without me changing something, i.e. increasing the engine speed. After I changed the engine speed and waited a little while (half a minute or so?), they were at a new equilibrium, and again didn't change. To tell you the truth, that's what I'm thinking. I'm not an a/c guru by any means, but I just flat don't understand not changing it and the dryer while the whole system was open.
The condenser is going to get cleaned well before we start peanut harvest, but I tried spraying water through it just to make sure it wasn't the problem, with the single result of lower high-side pressures, and no noticeable change in cooling.
I can certainly see the benefit in my climate of having some added insulation between the roof and the top of the evaporator cover, I may do that next time I'm in there.
On a side note, I emailed Tommy Martin in Pelham a link to your tricycle 4250 pictures from the other day. I haven't talked to him to see what he thought, or if he shared them with the rest of the guys at the dealership, but I thought he'd get a kick out of them. I told Andy about it, and he's pretty sure he's got a customer that would want one if he saw yours. LOL.
Thanks,
Adrian
