I found this rusted area in my spare tire compartment while lubricating some things. * see photo
This is what is attached from the other side. What is it? And is this an issue. It's pretty bad by my estimation.
Not sure how to proceed. I have a welder coming to look at some other things. Perhaps this will be added to his list.
Not sure why the photos are randomly upside down
Throw me a bone here.
top picture :: a bay outside post? looks like a patch on it before. usually caused by salt in winter/and moisture collecting... 2nd I'm not a mci guy! Have heard of some having to rebuild air bag support on rear axles(top) sorry hope some mci guys chime in.. there is a mci web site... Bob
Since it looks to be tied into your front subframe at least somewhat I'd suggest it might be a good time to replace the rust with fresh steel. Probably not critical but your bus is too nice not to fix it.

The second picture shows a bar that keeps the front axle assembly in its proper place under the bus. You definitely don't want that coming apart!
1st pic is the back bottom support for the tire compartment and have your guy cut out the bad crap and repair it than lots of paint to stop it from happening again . I don't think the support is for anything structural other than the spare tire compartment

Thanks for the input.
What Dave said :^

The circled part looks like it might be separating, but I can't be certain from the picture. I agree with everyone else about the rusty panel in the spare tire compartment.
looking close that looks like a repair. definitely 2 different people welding styles. think you need a bottle of crack detector.
I really appreciate the additional input.
I know the world's best welder. So I'm sure he can make it right.
I hope he's not the world's most expensive welder...
What is it?
Clear 1/4" rubber tubing coming from the engine compartment.
This was originally tied into the sink drain.
I'll give you another chance...
Do I win anything for stumping the forum?
wait a minute. Everyone moved onto next post.
Ok...since you guys let me down in my time of need, I took it upon myself to try to figure it out.
This tube of course comes through the wall from the engine compartment (see pic).
So, I poked my head into the area I thought it may be coming from.
Well...I have a pretty big head and got it stuck. Now when I say I got it stuck, I don't mean stuck-stuck.
Basically, it was just wedged in there tightly. Not a big deal. But I shave my head about 9 months a year. So you can imagine it wasn't real fun pulling it out. No hair as a buffer from the rust and grime and bolts and wire ties, etc.
Anyway, this could have all been avoided...
Sorry to hear of your misfortune. I would like to have responded but don't know much of MCI as we are a GMC bus owner. Glad everything came out alright - literally!
drain tube from ping tank or from aircleaner for rain water drain?
That tube may come from the engine compartment, but does it originate from there?
Perhaps it passes through the engine compartment but starts somewhere else, like a rooftop a/c unit where it served as a condensate drain.
Most of the OEM drains I've seen have been either black rubber or copper lines. Don't think I've seen lots of clear vinyl tubing being used from the factory on a vintage bus.
Something to do with the now removed lavatory? That'd be my best guess in which case it would be unimportant.
Jim
just rip it out and see what happens.
my MCI had a air line that went up into the crapper that I had to cap off but I can't remember what it was for ???
dave
Unlike social media, here on the forums, people are better at keeping silent when they don't know.
Do you really want half assed answers in the last places there is sanity?
Happy coaching!

The newest episode of "what is it"?
And why do I want to flip it? It even has one of those red covers that should make you think twice. Just like in the movies
This is in the rear jbox
Here is the pic
Get one of those cheapo Harbor Fright wire tracers, then you'll know exactly where it goes and what it does without any drama or rude surprises! The HF one I have isn't the world's best tracer, but for the occasional few times I use it it's OK.
John
If I remember correctly that is the fan clutch test switch

The j box is labeled. That was an option although the diagram didn't match exactly. Left me wondering...
Oh, definitely flip it. How can you not?

According to the wiring diagrams, if you have a push-button ignition, that switch functions in the same way as the "run" switch does up front, enabling you to start/run the engine from the rear without flipping the "run" switch up front. If you have a keyed ignition, then there appears to be no use for said, pictured, switch.
Our '99 DL3 has this switch but also keyed ignition so it doesn't do anything. Was hoping it enabled the flux capacitors or something similar, but no luck. ;)
Happy bussing!
Its that time again...
What is it?
I basically know what it is but I need to know what its called. I need one. It is on the 24V bus bar inside the drivers side jbox.
The part is a Klixon circuit breaker frim a 2000 102-DL3.
The MCI part number is 7C-13-128.
The Klixon part number is 7849-2-20
A few Google searches lead me to think iit may be difficult to source. I reached out to a salvage yard. Yet to hear back.
I'm adding a circuit for the purpose of converting my wipers to electric.
Ebay has a lot of those and Texas Industrial Electric in San Antonio probably has it or can cross it over, I will look today I may have several of those in the shop ,it is just a circuit breaker any should work with the right amp rating,the Klixon number tell you it a 2 connection 20 amp breaker
