B series AC question

[jmfox]

And all this takes place in the condenser coil ?

For purposes of resolving the presence of water in the TC cab, I think the fact that liquid water is a byproduct of air conditioning is all we need to know. I trust the condenser and discharge are mounted outside the cab, so the water must be caused by uncirculated/trapped warm air in the cab that is cooled/dehumidified outside of the AC process. If this is the case a strategically placed circulation fan in the cab would disperse the pockets of air and keep any rain clouds from forming in the cockpit.

I think you maybe using the wrong terminology. This is why Willl is stating your are wrong. The condensor coli is the hot/heat exchange coil located near the radiator and is on the high pressure side. The evaporator is the cooling coil located near the cab/interior. The cold evaporator coil results in the "condensation" and water formation. I suspect the drainage from the evaporator coil is blocked and therefore running into the toolcat cab.

Yes, I am referring to the condenser and evaporator as a single process. These components should be distinguished, this is why it is good to do your homework kids. The evaporator on my Red Dot system is mounted on the roof and drains down the outside of the back window. Where is the drain on the TC and what is it about its design that allows it to be exposed to junk and backup into the cab? There seems to be a pattern here with TC radiators/evaporators that are designed to collect junk.

I found the drain tube. Using a shop light I found it near the boom lift cylinder base. It was clogged with what appeared to be paint chips and some debris. I used the end of a welding rod to poke around. when the debris came out, it was followed by a steady stream of cold water. I think I found the reason why my cab has been leaking water and according to the first owner, leaking from day 1. It didn't look like it had ever dripped.
Thank you all for your help.

Well, I have the AC draining but now the condenser behind the in cab filter froze over. It was very humid out but I think it may be my in cab filter has seen better days. I have cleaned it numerous times but it was so used to being wet and sticky, that I don't think it lets much air pass through. I am hoping i don't have a freon leak or a thermostat problem. Anyone else have this happen?

 

[radman1]

Your on the right track. Probably not enough air flow in the air box and high humidity resulted in the freezing. Change the filter and run the fan faster and the A/C control on a warmer setting.

Our humidity levels have been at 70% + most of the summer which has been tough on all my machines cooling. I'll try what you suggested and see if that helps.

My deales says I have one of the earliest A models and that is why my drains are under the plate on the bottom of the cab. He says that there was a bulletin for a relocation of the drain to the area yours is to "improve" drainage. Must not be a perfect fix, huh?

still tough to get to the drain. I think they should have just had a tube that ran out the cab. Could have had a hard line against fender wall.

goatman,

Yours sounds like it is more protected but harder to get too. Would be nice if it was accessible from inside the cab where the filter slides in.

I have not seen any water in my cab so the drain must be keeping up. When it's really humid out I get condensation on the outside of my windshield and have to run the wipers intermittently. The A/C will freeze you out of the cab though.
