Cool New Canadian Skoolie - A Toy Hauler!

Hey everyone!

I bit the bullet last Friday and drove home my new to me:

1991 International 7.3 IDI w 4 speed auto 66 Passenger Corbeil body bus.
Only 121,000 kms on it!

Couple things I settled on - 1 is that it's an auto.. I definitely wanted a stick shift. 2 is that it's geared for roughly 60mph top speed. Until I change all fluids I don't want to push it, but she's humming along at a solid 2800 rpm I'd say at that speed.

So I'll have to dig in to see which slush box it has, and what rear end gears it has. Hopefully it's a strong auto, and that I can find some gears to give the bus some longer legs to lower the rpm at speed.

Hydraulic brakes, seats were all removed except for the front cushions. Oh and ALL of the heaters in the bus were removed (prev owner used it for storage for the last 7yrs, but started and ran the bus every 6mo). Needless to say, ALL fluids will be getting changed.

Runs well but I'll be doing a ton of overhaul to the whole thing - my project is to create a Toy Hauler RV for going sledding in the mountains, dirt bike or street bike trips and all around being able to simplify life whenever I want.

I'm starting this build thread to get feedback as I go along and hopefully learn from others great ideas as well as their mistakes.

I'm just outside of Calgary - I can look at the Rocky mountains out of my kitchen window, but I'd rather be in them on foot or on a toy!

Any other Albertan's here?

My friends all started out thinking I'm nuts, and its quickly turned into them wanting to be on board - and I've told them to enjoy it later on, they gotta help me first!

So far I have 2 days of tear down into it - I've pulled the last of the seat rests out, the front bumper mechanism, the side stop lamp, the front convex mirror frame (mirrors were missing anyway) and am working on the tear out of the floor so I can prep the bare metal, seal up the holes and then start to cut the rivets out of the back and move the rear section of the bus roughly 9' forward to expose my new toy hauler deck!

I tried to attach pictures and it failed. I'm tired. When I started writing this message my laptop just shut off on me so I completely disassembled it (thought I ruined it in the process) then googled how to do it properly, and finished the job, cleaned the fan out, and when it powered back up - here I was still on the introduce yourself page. The fact that I didn't eff that up was great because I don't feel like spending money on anything unless I need to. (Our current Premier is arguably the biggest socialist bonehead ever elected - so the whole province has been going to Poo in a hurry and of course that affects the spending money or in this case lack of.) Anyway - not here for Political chit chat so .. end rant.

I was en route to buy a wood stove when I got a text back from the seller that he was around so I ended up driving a hell of a lot that day. Needless to say I was committed to the project because I was buying the wood stove before the bus

It turned out to be a great deal so far and I'm looking to make it quite nice but on the absolute cheap skatiest budget ever. Yep I made that word up. Canadians eh?

I also need to name the Beast. That might take some time.

I'll be working on the bus every moment I can, but it's being stored 45 mins away at an acreage because I live in a new neighborhood with no do what I want space.

So - First Question - does anyone have the 93-94.5 turbo 7.3 IDI parts that they would like to get rid of, and has anyone done the swap from NA to turbo and can walk me through what is all involved? With the elevations that my bus will see, I'm going to need more pep or its going to be a LONG drive all the time.

Ok so here's the update. I figured out from the diagram post of AT545 vs MT643 that I have an AT545.. although mine has a drain plug on the side of it and what looks like a temp pickup sender on the upper part of the oil pan as well. But the side of the case looks exactly like that photo of the AT545. So I'll go with that. I searched for the info on the rear diff and I'll have to call international tomorrow to see what gear ratio I have but from the sounds of it I'd venture a guess at the 5.78 due to the top speed of the bus.

Tore out the rest of the windows and most of the flooring and found I have a couple that are double pane glass. I'll have to fix the release buttons on them but they'll be great for the 4 window's I will keep in the bus. We also started grinding a ton of rivets on the outside near the back door of the bus as this is where we will detach it, remove a section of the bus, and then rivet it back together so that I have a 9' flat deck on the back end. Then I've gotta get the rest of the floor up, cut all the screws sticking up off, clean it and rust convert it.

I had my 2 cousin's and a cute female Pilot helping out - we tuned up her bike and in return she helped with a bunch of help removing windows on the bus. Then Sunday we all worked again and stopped to teach her how to back up a long trailer like a champ, and how to wheelie her bike with control. A great day for all!

I just tried uploading 5 pics that were all jpg or png, less than 1600 x 1600 as per Paint and less than 2MB and they all failed.

Anyone know how to fix this pic upload issue?

Have you considered leaving the roof over the rear area? There is a lot to be said for having a "covered porch" and I have seen more than a few done that way.

PITA to have to use another place to link photos. I probably won't post many pics because of the hassle - unless someone has a question.

Thought about the covered porch style but decided it wasn't going to be the best option for me.

On a positive - I found out from my local IH rep my bus has a 5.38 rear gear so it looks like 62 mph is 2800 rpm. He also let me know for a cool $3000 that he could have the diff swapped with a rebuilt 4.44. I thanked him for the offer but that's way more than I spent on the bus!

Transmission Ratio RPM Calculator

With this calculator a 4.44 would be cruising at 65 mph at a sweet 2400 rpm.

Chances are unless I stumble across a ridiculous deal on one with hydraulic brakes and its' the entire axle, I won't bother with the swap for how many km's I'll be driving per year.

The IH rep also confirmed it is an AT545 so I found this tidbit on the specs of that transmission.

ALLISON AT 545 TRANSMISSION SPECIFICATION - Topic

Once I've got the rear door moved forward and the floor all rust converted, then I'll focus on a full mechanical checkup - change all fluids, etc.

There's a lot to learn on these things and WAY more work than learning!


Oh and one more thing - what do people usually do with their extra windows when they are pulled out? Anyone looking for a bunch of them?

Throw the removed windows up on CL for $10 a piece. You'd be surprised how many people grab them. They're especially popular amongst ice fishermen. Many use them in their ice huts. Looks like you may be in ice fishing territory.

Good luck!

And put some wrecking yard calls out for that 4.44 gear set. The installation should be no more than a grand or so. The improved engine life & MPG would be worth the difference if you plan on doing much highway driving.
