Transmission cooler size

[thomasinnv]

Andrea that little pipe looking thing in the rear access door is the ping tank. It should be drained regularly along with the air tanks. If you connect shop air to the fitting in the bottom it should air up the entire bus air system. If it doesn't then that means it is plugged. Take it off and clean it out. That is one item that gets commonly overlooked.

The little blue airline to the left of the entry door probably used to go to the airlock actuator for the door. It gets energized only when the door is shut all the way with the handle pushed into the lock position, and the ignition on.

The emergency fill under the driver seat...there should be more than one. There should be one connected to the park brake system and one to the aux air system I believe.  Just going by memory there, but you need to get the park brake emergency fill in working order at the very least. That is how a wrecker company releases the brakes if you ever need a tow.

Scott, that cooler is one of your problems, looks like that is shop made cooler how in the world would you replace the tubes if it developed a leak.Do you have a photo of the complete system on how it is plumbed from the water pump ?. The air to oil cooler I have measures 30x40 inches from the outside of the tubes

Scott the idea and method Stormcloud Mark mentioned really sounds like a great setup. The idea of electric fans on thermostats is, in my opinion a perfect oppurtunity here. Of course theres always the locations available. Just sayin good tip there, and we all been using hyd hoses for doorways or in part movements a long time. Keep up the good work!

Have a good weekend everyone 🇺🇸

The cooler my friend gave me is about the equivalent of the 2292 in the chart. but 33 by 24 overall size, so a little bigger.  I guess too big isn't an issue if I have fans on a thermostat.  I was actually planning to try it without fans, if it's where I plan to put it, or in a door, it will get lots of natural airflow from the engine blowers.

Thanks Guys

Dave... Your bus looks like mine, minus one axel. Same rear cap.I have a couple of questions. What is that cap on the top holding the AC units?

And...entrance stairs, left as you open the door. I have a blue line that is capped off in that little box. I don't suppose a girl could use that (along with the little 12v air compressor and miles of air line dad had laying around (that he never got around to using) to create a way to air up the bus air bags? The front emergency fill valve under my driver seat is disconnected, all those lines go to the E-6 brake valve (I think) and the quick connect in the curbside rear access door doesn't seem to do a darn thing. It goes to the bottom of a small round canister. That canister also has a BIG tube from the Tru-Flo 700 compressor. BUT...I do NOT think it's a dryer. I have looked up every dryer DD ever made, and this doesn't qualify. It has no drain, nada.

Any thoughts?

The extra roof on top of our Bus is because it is a Saudi Coach. Its just an extra piece over the original roof that air goes between to give it cooling when it was over there in 120 degree weather.

You should look into re- hooking up the fitting in the tool bay under the driver seat area. That is for a tow truck or hauler to hook up an air line to it , to release the brakes so he can move it if not fully aired up.HTH

Cliff I'll post more photos of the setup tomorrow. No one has seen this cooler setup before?

Here are more photos of my trans cooler plumbing, sorry Brian for the thread takeover...at Least it's on topic lol. It appears they tapped into the side of the engine block where the block heater would go. It goes to the trans cooler heat exchanger and then back to the engine block. That lower large bolted box that the lower coolant tube goes to is a mystery to me. Not sure what that is:

I don't get the plumbing on that setup the cooler should be directly off the water pump but your engine oil cooler is plumbed there I never saw that before on a 8v92

[azdieselman]

I don't know about your cooler, But I see some hoses that need replacing!

[Dave5Cs]

Kevin you beat me to it. Second picture for one on the leftside of it has two rips in it eh...

Cliff do
You mean engine oil or trans fluid? As for the hoses meh, just flesh wounds lol.

The first cooler is a engine oil cooler,most 8v92 in buses had what we call a double,double cooler mounted on the side of the engine 1/2 was the engine oil the other 1/2 was for the Allison,your setup looks like originally the engine had a manual transmission and somebody added that cooler.The double double DD cooler did a decent job cooling the engine oil and transmission fluid since the coolant passed through the cooler 1st then through the engine to dissipate the heat

Ok, Andrea, here's the photos of my trans cooler. Kinda a bad idea in my opinion on an 8v92TA coach...these engines already are at the limit keeping them cool, they certainly don't need trans heat too. I'm working to eliminate mine and go with a separate trans cooler altogether.

Cliff, can you please let me know what kind of deal you might be able to make me on your Allison cooler? And can you tell me the exact measurements?

Oh lord no. That thing is HUGE!

As soon as my phone charges, I'll snap a pic and post it. I will so gladly take it off and clean it if I can use it to air up the bus. Thanks
