1985 Eagle Model 10 - What are these hoses?

[ScharpeStGuy]

Hello all, removed old bus air ducts in last bay and the two rotary fans today. This leaves me with some large hoses and two long radiators in compartments on the inside of each bogie wheel. What are these hoses and radiators? If they were for the old bus air system they are coming out.

Thanks everyone.

They were factory for the HVAC system you should have fresh air vents in front of the fuel doors too

And the pic...

luvrbus, sorry I had to break out the laptop to post/resize the picture. So the two radiators and the green/red hoses can be safely removed?

Thanks.

Yep that is the house HVAC system,you will need to re pipe after you remove those to get heat to the front heater and defroster, there should be a booster pump some where in that area too 

[ScharpeStGuy]

Would anyone have a schematic for an Eagle Model 10 HVAC system? Looking for additional info on the re-piping / booster pump.

Thanks

I know quite a few people who remove the coach heat/AC when they start their conversions. I suppose what I can't figure out is why?
I have a totally different coach (system always worked well...now 134A), and although I am now cleaning it out, even the chore it is... I can't imagine what I would do in the summer without it. IDK about you all, but I would literally bake with those 2 huge windshields.
As odd as it may sound, I would appreciate feedback from those of you who remove the system? Why? and for those with the 2 level floor (vents)..how?

I apologise if I've breached posting etiquette, and I'll start a thread if that is the BC method

A bus AC system is great, when it works. Maintaining it will be expensive. It is probably the highest maintenance item every year for a bus company. You can easily spend $1000 and up every year getting the system topped up, and looking for small leaks that will drain it empty every few months. You might be lucky and have a tight, leak free system. Nothing comes close to getting the bus cold on a hot summer day than OTR AC. It is also the best to remove moisture out of the bus in the winter to keep your windshield and windows frost free. But I have driven lots of buses, new and old, with small leaks where the AC wasn't really cold. That is a big problem with a full load of passengers and windows that don't open. So keep in mind, if you want to keep the stock AC, maintaining it can be expensive. You still need roof tops anyway for when you're not driving.

The picture jogged my memory.  That spring loaded valve and all those lines should be removed.  It all Tees off inside the tunnel which you have covered up in the photo.  Remove cover and you will see main lines and tees.  Keep the main lines for the driver's heat and defrost to the front.

Hey JC.
You are right about the potential for yearly expense. Our second bus was a leaker. The current bus however, has been switched to R-134a, with a 05G compressor. It's a tight system, and if not for my current desire to make sure all the vents are clean, I'd be golden.
There are more people that remove the system than keep it, and I've got three 13.5k roof units. But on a hot day, from the Captain's chair, I would never know it. Maybe I need to find a legal way to tint the windshields...or find new ones that don't bake me

daddysgirl,

Check out the sun visors in any new coach, the wide roller blinds...

You do have the black-out tape on the driver's windshield above the existing sun visor?

happy coaching!

They remove it because its 1$ a foot for copper.....

No black out tape... Don't I wish.
The only difference on the left windshield is the tan-line difference on my legs between the visor up or down.

[buswarrior]

No tape?

Do something, anything until you source some good stuff. Masking tape and something.

Note the tape coverage in the front of RJ's coach, same windshields as yours and mine.

happy coaching!

Holy Cow!
Great idea. AND if not for the windshield (my passenger side still has a destination sign (I haven't gotten there yet)cand box roof line, I would have thought that was my bus. SAME color green.

Please define "good stuff" What am I looking for, if no plain window tinting?
