No prob!
Good, I am glad you found someone knowledgable at last!

Here is the bottom line.
Make sure everything is there, connected as it should be, and functional.

Get a good knowledgable shop to check/clean/rebuild/set up the carb to pass smog and you will be good!

One thing I suggest you have done...
Repplace EVERY rubber pipe in the fuel system, or at least have it checked... The new fuels rot the older pipes out and you will fail on leaks... eithe fuel or air leaks will fail you.

OK, now I am on the schedule for emissions testing in Novato but I know I get an automatic fail without an intact original emissions system. I suspect I'm going to need to find a serpentine pulley because I'm pretty sure that's what I'm missing. Does that sound familiar to anyone? And if so, I guess I'll ask whoever is parting out their coach - I remember someone was - to see if someone around here has one. If that doesn't ring any bells with anyone I guess I'll go and get failed so they can tell me what I'm missing.

Problem is, I have very little time to handle this before I'm away for a long time, so getting a part asap would be ideal.

Jenniflow..
My books tells all....
In fact in 1986, the GM Class A Motorhome cahssis emissions were identical for Federal and CA equipment!

So, here is the list.
No Computer, Quadrajet 4 barrel carb, timing set at 4deg @700rpm.
PCV, ACL, AIS(Air Injection with 2 airpumps), EGR, EVAP, SPK, and no o2 sensor or catalytic converter.

Your MH should have 2 airpumps for the AIS system, one is on the passenger side lower front of the engine, and one on the top between the alternator and AC compressor.

RockAuto's site states that they carry both airpumps..

A-1 CARDONE Part # 32285 Reman.
Upper Pump; with Federal Emissions; Pump Stamped JK $77.80
-1 CARDONE Part # 32244 Reman.
Lower Pump; with Federal Emissions; Pump Stamped FT $84.80

Both are shown without a pulley.
I suspect that there was an issue with one or both of the pumps, and they were bypassed...

Yay! Excellent. Thanks so much! Now I can go in, knowing exactly how they can and can't rip me off! I have an appointment on Monday. Hopefully, we can get it all working soon after. I'll need a tune-up and I'm hoping for relatively easy sailing on that score.

Then there's the wipers and the master cylinder ... but hey, who needs to brake and see, anyhow?

When CARB was formed in the late sixties, I was handling the advertising and marketing for a number of speed equipment manufacturers. People at DMV didn't know anything then either! There was a window in the late eighty's that exempted MH's. HOT ROD Magazine did several feature stories on building performance engines that would pass CARB standards. At one time, manifold manufacturers were casting units without logos and suggesting that the buyers paint them with the correct engine colors. Every time the speed equipment industry built CARB compliant equipment, they'd change the rules. One of the reasons I live in SW Colorado!

Geez. That's interesting. It's all a little too complicated. But the regs sound more sympathetic to the old-vehicle owner than I originally thought.

I strongly suspect that Keyair, (like the good lad he is) is trying to lead you to water, and save you some agro.
In other words, find out if those air pumps, (or pump,) are actually able to rotate. If they can be turned put the belt on. Are the "big" hoses from the
pumps to the air injection system there? How about the air injection pipes? (they go into the exhaust manifold)
Any mechanic, or mechanically inclined person, can tell very quickly if the parts are there.
If so, then go get your emissions test.

But before you drive that 12000 lb vehicle.

*** ! Brakes come first ! The Brakes should be your first concern above all else!
Knowingly driving with bad brakes is willful negligence! ***
Please, please, do not take chances.
We really do not want anything bad to happen to you.
All the best. Cheers! Rich.

You are completely right about brakes first, Rich. I have been hoping that Airslide would be able to work on the brakes on Sunday but we're having a deluge here and it looks like it's not going to let up by Sunday. I did drive the coach 3 hours from up north, not realizing that the brake light might have been referring to the foot brakes and not the hand brake and, though they were a little softer than usual, they worked pretty well. I had no trouble stopping the vehicle.

Are you saying that they could suddenly fail with this MC leak problem? or that they will gradually weaken? If Airslide can't work on it on Sunday i'd have to drive her to get someone else to work on the brakes or have her towed. I only have a week left for this stuff before I have to move on to the next thing for quite a while and I need to get her registered one way or another.

If Vinnie is able to get here, he might be able see whether the pumps are in place, although I hear he is a "trailer guy." ;-)

OK, so I'm going to get her towed on Monday to a local truck service if Vinnie gets washed away. I just lined it up. Thanks you guys. Very bracing advice!

Yes to brakes first!
Yup Richie, just trying to help and save time and money where possible!

As far as the smog goes, I have done SOOO much research and learned so much about it... which is why I started this thread, to educate us all and share what I have learned!

Keyair and Airstreams

Yes Jenni, Keyair is really a major help to any and everyone on these forums!
Keyair and some of the other guys have saved me hours and days of work and indecision since I bought my 345 in 2007.
Master cylinders are nothing to be casual about, especially old ones. They might leak for ages and not go out completely. Or, if the piston seals are rotted, they could fail in both circuits at once, unlikely, but who needs to find out the hard way? Besides our Airstreams are very heavy, and at the edge of braking safety when everything is working correctly.
Just not worth a tragedy.
The truck place should also be able to take a look at your emissions equipment and tell you exactly what it needs.
All the best. Cheers! Rich.

Unfortunately, this truck place is not interested in my emissions system but the guys up the road are. (Yay) But I may have to store it on a non-op before I have time to do all that's needed. (Boo.)

And yes, I know what you mean: Mine is 16,500 pounds and is definitely a body in motion that tends to stay in motion in the best of conditions! Good Sam has this one. Let's hope that'e enough towing for one week.

I'm sure I have the pulley you need. The 345 I dismantled was an 86 model with all of the smog equipment present.

I am out of town until Monday afternoon.

Let me know which pump, upper or right side.

Brad
