Re: Out with the old, in with the new 7 window

I wish I could come help you. I really enjoy the thought of helping others become Mobile.

I don't think school buses get warm enough inside to accumulate condensation when being used as a bus.

I didn't realize you were reinstalling the steel on the roof. If you can, find something other to sheet the roof with like thin ply wood. The steel is still going to pull cold through the rivets and screws. Not as bad, but will still likely develop condensation on the rivets and screws.

Here Is a diagram to help.


Note that the steel screws from the inside never touch the steel on the outside in the second illustration. They go into the wood only.

Hope this helps. Your insulating looks really good.

Re: Out with the old, in with the new 7 window

Well, now I get it! Oops. I am going to be okay with visible condensation, at least more so than hidden! If I had done the furrow strips it would have been A LOT easier to reattach the original metal (i.e. no self-tapper or pre-drilling) Oh well, next time.
Today I painted the metal put in yesterday with an almond rustoleim. It is going to look great once the wood is up. I also removed the old flooring. It wasn't that difficult to my surprise. On the full size (carpenter body) the floor was a total nightmare. Had to get the big ole floor scraper and go to town for hours on the adhesive. This one (Bluebird body) it was up in half an hour. The rust is minimal and all appearing to be on the surface only. Got any loose stuff off with a stiff putty knife. Plan on wiping it down with low-odor mineral spirits and then the rustoleim metal primer.
Also, I did some reading and bought 15W-40 weight oil... said somewhere to use 10W-30 in <20*F??



ALSO: I tried asking the local wheelchair/mobility places in town and none of them were interested in the wheelchair lift. Said it was too heavy duty for most of their applications. If anyone has an interest or knows were to sell something of this caliber let me know.

Re: Out with the old, in with the new 7 window

It's rare to sell a wheelchair lift for anything other than scrap.

Re: Out with the old, in with the new 7 window

I put that sucker on CL and took it out.. If there are no takers maybe I could take the metal to a welder in hopes of a min back porch and propane tank shelf. Has anyone ever used a smaller bench seat, from a van maybe, as a driver/navigator chair? The front stairs kinda turn towards the back, it may not be that awkward?

Please post pics of the lift. I haven't seen one in person yet.

Thx

Re: Out with the old, in with the new 7 window

Unfortunately, it has been my experience that these lifts are not inexpensive to maintain. There are a lot of sensors on them that go out of adjustment and/or bad. The manufacturers charge a premium for them. I'm a transit administrator and I see the cost associated with lift systems every month. For instance, we have a lift system in a particular model bus that has two 12 volt light bulbs that illuminates the ramp. The light fixture is a design that will not allow the use of a typical 12v bulb, so we must buy the specialty bulb from the lift manufacturer. Its shape and lumen output preclude the use of any other bulb. That bulb costs us $20 each whereas a typical 12v bulb might cost us a couple bucks. And, the lifts aren't the easiest to troubleshoot, with some of them having IC boards that control everything. The newer they are, the more complex they seem to be. The typical lift capacity is usually around 600 - 800 pounds. The cost of purchasing and maintaining lifts was the main reason that the transit bus industry went to low floor buses, although there were other considerations as well. The ramps in low floor transit buses greatly reduced the maintenance cost of maintaining lift systems due to its design simplicity. But it cost the bus manufacturers millions to redesign the buses as low floor models. Due to the space available under low floor buses, special rear axles had to be designed that had a small pumpkin size. This axle was greatly complicated by requiring a sun gear at the end of each axle to get the right hub speed. As you might guess, this is a very expensive axle. The sun gear assembly costs about $2,000 for each side. Currently, the FTA is considering another redesign of the lift system by specifying a change to the max ramp angle allowable for the wheel chair ramp. This is probably more than you ever wanted to know about wheel chair lifts, but be aware that they can be expensive to maintain.

Re: Out with the old, in with the new 7 window



Here is the video we took of the lift before we removed it (click on image?, and there is another pic of it on page one of this thread).
Feels good just to get it out of the way! Looking at its pieces there is potential for a lot of reuse. Yeah, I doubt I will be able to sell it. Although, mine does not have a computer "brain" and appears very simple (thank god). I disconnected it from the battery and opened up the main panel and found a big ole solenoid and simple appearing switches. It only has one hydrologic and essentially does one movement. We pulled a few of the pins which was not necessary, so now it is a huge scissor wanting to take your fingers off. About that light... I'm about to go check out the unusual light we could not get off of the ceiling panel above the lift (just left it on the panel and unhooked the wires). I am willing to bet it is the light you are talking about...! (let ya know)
I got a bench seat really cheap from a junk yard. It is only 3'8" wide, so I think it will work well. We got some of the wood up on the ceiling last night. We used the 5mm hardwood ply board. It did not want to conform to the curve all that much but it worked! And, I think it will look great. There is a rippling pattern of the frame rails. I should have done furrow strips in general but most certainly where the union of the inner skins meet. BUT the wood follows the up and down waves of the metal perfectly.

Re: Out with the old, in with the new 7 window

Just want to put this out there if anyone has any ideas...
As you may have read previously: I have a 1992 7.3l non-turbo international 7 window carpenter.
So, we drove it home (it is was a 170 mile trip) and there were three vehicles always in this order: First = lil buck (slow Toyota pick-up, 55 max usually), Second= the bus, Third = Adam's truck (Mazda pick-up)..
When lil buck was going slowly (55mph) on an Ozark mountain down hill, and the bus had to let off the gas to slow and match pace with lil buck.. Adam got a huge plume of black, diesel smelling, smoke in the face. And, the bus got horrible gas mileage.
Question:
Is there a fuel return delivery problem, and fuel dumps out the exhaust??? The folks we bought it from had to change the fuel pump in the tank. It wouldn't stay running past the fuel dumped into the filters.
{also, very curious about the "throttle" pull... could it have been in the wrong position or something? When it is depressed it seems to be idling too low. And the guy we bought it from drove it with it completely pulled outward so it was left the same, i think.}
Thanks for the input, I'm a newbie when it comes to diesels that's for sure.

(the bus sat for a bit on the school lot, not in transit, before I got it)
