OTR A/C removal, advice needed.

Devin & Amy · May 22, 2007, 01:28:26 PM

Hi all,
Well, I have to remove the A/C system from the MC9. I don't have any idea on what is the "proper" place to start.
I don't want to help the hole in the ozone in the first place, so how to capture the freon?
Second, what parts to remove, and in what order?
Third, are the parts recyclable or resellable?
Fourth, anybody need what I have?

Thanks for any help provided.
Devin

I don't want to help the hole in the ozone in the first place, so how to capture the freon? Talk to someone that services automotive AC, they will have the equipment to remove it
Second, what parts to remove, and in what order? The order doesn't make much difference once the system is drained of Freon, Compressor and relays in engine compartment, condenser, dryer, and fan in condenser compartment, (and if you are removing bus heat, the evaporator, heater core, and blowers
Third, are the parts recyclable or resellable? Compressor, condenser, and evaporator, if you can find someone that needs them (maybe a local charter operator?)
Fourth, anybody need what I have? Not me Jack

Devin,

I'll second what Jack has told you...

List the parts on our site here, I'm sure you will sell them this time of year.

Hi Devin & Amy,
If your A/C system is still functional, you may find a local bus or charter company that will not only buy your components, but will remove them as well. I have heard of others being that lucky.
Best wishes, Sam 4106

Devin,

I just removed mine from my MCI-9. My system was not working. The belt was removed from the compressor, long before I purchased the coach.

I started with the large hoses in the conderser bay. When I crack them open, there was very little pressure. Took just a few seconds, say five, to stop hisssing.

Once the large hoses were removed, I took the condenser out, then the small tank that the hose was connected to. Removed the large blower, what a pain in the @$#. Took lots of w-d 40, then a small saw. Next the small blue tank in the upper left side.

Found a sheet metal shop and had new flooring cut to replace what I took out. While I was at it, I put a new pan on top of the metal on the left side. Of course everything was painted before going in.

Next I tackled the compressor. Lots more w-d 40. Sprayed the bolts, then removed the hoses to it, and the control wiring. The compressor is REALLY heavy,,,,, laid a large wide board in the door way, and dragged it out, myself. Currently it is still resting where it landed.

That's how I did it...

As you will here on this board,,,,,, Do it Your Way!

Hope this helps. Where are you?

Hey guys, I was reading this thread and was wondering if the old factory ac squirrel cages could be use to supply more air to the radiators to help cool the engine in a situation where you might be having an overheating problem. I know the units will move a lot of air. Some guys are always looking for ways to keep things cooler, like bigger rad's, or a misting system. I am sure someone has probable thought about this and wonder if it might work. Just trying to think outside the box. If you decide to flame me for a lamebrain idea please use BBQ sauce, I like
KC Masterpiece extra spicy LOL.

WVaNative,
I had considered doing that on our MC-8, I do not remember the number, but that big heater core can expel a lot of BTUs. My plan was to reshape the ducts and install a flapper valve so the air would be vented out the sides or down through the bottom instead of the inside of the bus when you needed additional engine cooling. But as plans change, we ended up ripping out all the "stuff" in the heater core/AC evaporate compartment to make room the the generator fuel tank and enlarging the condenser compartment for the generator. I still think it would work. Jack

So Jack, Are you saying is, that what I was thinking was not so hairbrained after all.
That alone made my day LOL. Good thing is "No Flames" and I still have hair on my body and I don't smell like BBQ sauce. I'm glad I am not the only one who thinks like I do.

If functional, I might be interested in the condesor, evaporator and other small parts you take out.

Let me know!

IBME that the biggest reason for overheating problems has not been the BBQ sauce, but the weight of the operator's right shoe. That and not downshifting early enough to keep the RPMs in the sweet spot for cooling (1800-1900 on a partial throttle).

Devin -

The suggestion to contact a local charter company is an excellent one. Try to follow up on it. Otherwise, if you cannot find any takers, a metal recycling facility will give you scrap prices/lb for the components.

FWIW & HTH. . .

Thanks all,

I found a repair company who will remove the whole system for free in exchange for the parts. C-J

Really appreciate the responses!
Thanks

They will have to pry my cold dead hands off my over the road heat and A/C. Took it out of my first bus and I won't do that again. Buses use the same units as reefer trailers. I have Thermo King on my bus. All parts are available and it is cheap to maintain and very well built. Sure works good too! Did I say it sure works GOOD? No one is hot in the summer and no ones cold in the winter. What a great feature this is on my coach! I will never own a coach that does not have working" over the road" heat and AC.
