Transmission cooler size

[daddysgirl]

My spin on filter is the same size (orange rather than white)...and the pan appears to be similar to mine. I don't believe I have the large tube below the valve cover, but I can't see sh**.
And I am 99.99% positive that my 50DN is gear driven (18 teeth) and oil cooled. So, if I'm understanding you all, I might not see the cooler anyway?

I would do just about anything to have that dolly for a month or so. Where did you get it? Seriously...man, to be able to have my beauty out of frame...a dream.

I doubt you have the military oil pan on a 8 they hold from 10 gals to 15 gals of oil huge oil pans lol but if you would like one I have several.The military 8v92 the alternator runs off the blower 

[daddysgirl]

You of course, are correct. The pan isn't that large 

But I found another tube. I look all the time, and always find something...
This is a metal tube with a couple hoses that goes between the heads in the rear (I can see it from the access inside) then there is another larger tube above all that with a small valve like the crossover tube has.

I really want one of those dollys.

I made the dolly, 4" square by 1/8" wall tube and four 1,000 lb casters.  BusWarrior has it now, and my engine stands that I made.  You don't want one, to be honest.  What you want is the Evans ERS (Engine removal System) Mk 2, which is a $200 (less used) 3 ton pallet jack, and a bunch of 4X4's and 2X6's and such.  You take the pallet jack and build a cradle that picks up the oil pan flange of the engine with the lumber, suitably braced, and you screw the engine to the cradle with some big screws.  Works a treat, rolls a lot easier, and you can lift the engine up and down.  Now, the dolly I made was the thing for the time, because I strapped it to my tractor to push it around, and I was on a very rough pad that would have been hard to push the pallet jack around on.  But a pallet jack (or a full tile fork lift) is the way to go to pull an engine.

Pallet jack here with different cradles for different engines works like a charm

[daddysgirl]

If either of you could let me know where I can get one, I would so appreciate it!  PM if that is what is PC.
The only other thing I would need is to figure out how to get the bumper off 

[Dave5Cs]

You can get a pallet Jack at harbor Freight, Home depot, rental yard.  Look on Craig's-List and they in there sometimes for cheap. Even if they don't work generally its just a rebuild kit needed. A Single hydrolic-cylinder is all that can go wrong with them and thats just a seal. The little control valves are just steel balls that open and close.
Bumper just unbolts at the cradle ends. Lots of PB Blaster on bolts or heat to get them to turn. HTH

I believe the bumper bolts are the four little 5/16" ones that go through the big rubber spacers that hold the bumper out from the body.  Behind that would be a steel cross-member that bolts to the frame with 5 1/2" bolts at each side.  That crossmember is critical.

I'll try to remember to take a photo of my trans cooler tomorrow. It looks like a baby 55 gal drum on its side with trans and coolant lines running out of the ends.

Thanks Guys

Scott...I was looking at the same Guide. I need to stray a bit off topic. Apologies in advance... I try not to do this, but Daves Photobucket demands I ask a few. Please forgive me 

Brian, If I'm thinking of the same cross-member, its round in the middle and has several U-bolts to frame...in addition to all the lower steel rails across and in both corners.

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?

     That's VERY good info, Scott.  Did you get a URL for that site, please?   Thanks,  BH

The flow rate is very important don't down size to save space or you defeated the purpose and the transmission will run hotter air movement and flow can be come a challenge on a bus when adding a air to oil cooler   

[Scott & Heather]

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?
