Title: Bought a different bus today
Post by: Jcparmley on April 06, 2019, 09:35:48 AM
Well!  I bought a different bus today.  It's a 1996 MCI 102DL3.  I currently have a MCI 102c3 with a 6v92TA bus that I am still gutting but I just couldn't pass up on the opportunity to purchase a D series with a Series 60 with 40 k on the rebuild.  It's interior is mostly gutted.  The PO purchased it from California a few years ago and drove it to Wisconsin.  It dosen't have a Wabesto which is too bad.  The Windows arn't as heavy as my c3 Windows so I plan on swapping them.  My plan is to part out my C3. 

The PO tore out the upper luggage rack Air Conditioning by just cutting the copper lines.  So, my guess is all the freon is out of the system.  The PO says the OTR AC does work.  So I guess I need to cap those lines and recharge the system to see if it actually works.  I need to find the manuals somewhere so I can become more familiar with this bus.  Here are some pics.

I don't think it has jakes.  It does have a retarder.  I need to learn how to use that.  Jakes would be nice.

COOL! Same year as my DL3. They really stripped it out didn't they?

Each of those OH AC's had a solenoid cutoff valve on the high side but I don't know where it is located. If the low side is open it's highly doubtful you have any freon.

Great bus. Should have the B500 6 speed with retarder. Andy tells me I won't find much use for the Webasto (actually Eiberspaecher) because it burns 4 times the fuel idling that the engine does so you may not miss it.

If you would, could you check how your dash fresh air vent works? (you can easily lift and pop out the cover panel at the front of the bus to access that area, wash the filter and such. Does yours have just 1 T-handle cable for heater control? If so that fresh air damper cable has to go somewhere. Mine was removed and I'd like to know what was there to begin with and what you did to open and close the damper.

It should have lockable tag axle steering, rear lift for extra clearance, kneel, and maybe more.

The manuals are online at MCI but the ones I downloaded had the schematics cut off and are almost useless. Let me know if you find something complete.

I doubt it has Jakes just the preset % on the retarder on the B500 if you are lucky it will have a joy stick so you can control it, if it does have Jakes it will only be on 3 cylinders from the factory,those are not steering tag axles they just follow and lock in place at around 20 mph

That's an exaggeration.
"Andy" isn't helping you or us with this statement. Fuel burn is a fraction of engine idle.

Interior won't stay warm, engine won't stay at operating temperature.

I don't believe I have a Wabesto.  I don't see a control for one and I haven't been able to find one in the engine compartment.  Although, honestly I haven't found a manual yet so I don't exactly know where to look.  If in fact I don't have one how might I heat the coach?

Mine has just 1 T handle for the heat.  There is a button on the shifter console that is used to open a damper to let fresh air in.  at least I believe that is what it is for.

with my Cat if it is below freezing and I am not going up a hill the engine and the inside of the coach is cool not hot unless my aqua hot is on . if not my nuts get cold .
in the 2.5 days I drove from Florida to home this year the aqua hot burner ( timer is on the just the burner only) was on for 18 hrs of that time and the outside temp. was -10-15 cel . or 5-15 f so yes the other heat source is needed if you are driving in the cold weather on my coach

so 18 hrs x .4 gal. of diesel = 7.2 gal of diesel approximate over 1500 miles
not that bad to stay warm and have the engine at the recommended temp.

Open the roadside (left side) engine access door stick your head in and look up. If you have a webasto thats where it will be. I was under the impression that all D series coaches with series 60 had either a webasto or eberspacher installed, at least thats what my manual says.

That vintage D series when equipped with jakes had them on the first 4 holes, with the the valve cover dropping down flat under the floor over holes 5 and 6. MCI used different model jakes on those than what is used on other series 60.

Does anyone know what this is by the drivers left knee?  Is this a Wabesto controller?   I don't have a manual yet so I can't look it up.  Whatever it is I can get it to turn on.  I really appreciate the help.

Yes thats the controls for the webasto.

It's anybody's guess what the power is set to on your engine, only way to know for sure is to plug in to it and see. Thats the model number btw, not the serial number. A pretty common factory setting for that era would be 370/400/430 @ 1450 but like I said, only one way to know for sure. Any number of things could have been shoved onto that ecm over the years.

Mine was set to 370 @ 1450...I reprogrammed it to 470 @ 1550 and boy did it really wake it up.

I have a usb link and the DDRS and DDCT software, and a few hundred oem DDEC files. It's not as easy as just dropping a new file into the ecm though. The file has to be compatible with the internals of your engine.

Any authorized detroit shop can plug in and see whats what. The ecm will most likely have 2 or 3 power settings onboard, and it's just a click of a button to change selections. If they have to upload a new program, it can get a little costly depending on what's available from the detroit server for your serial number. Most shops will charge you an hour if they just plug in and don't have to do any software upgrades.

If you were closer to me I would be happy to swing by and plug in. Chances are pretty good I would have a high hp file that's compatible to your engine. Chances are pretty good that you are not anywhere near the output capability of the engine. MCI is fairly conservative with thier programming levels as shipped when new, and most charter companies didn't want them boosted either.

The square webasto control was my second favorite after the 3-day clock style for a driver to get the (profanity deleted) thing to fire in the morning while on charter work...

Not so much a busnut challenge, in fleet use, multiple fingers and abusive techniques... you'd think you had some of these set right... wake up and head out to start coach... no fire had happened...

A busnut coach has one set of fingers, with a vested interest, and not as likely to need the timer to avoid waking early, dressing, trudging out to the coach to set fire, back in for shower, breakfast... etc.

Probably the power disconnected to it. Do a full service right away, the PO would have disconnected it instead of fixing/servicing it.

Nobody likes to spend money on something they plan to sell...

Happy coaching!

I couldn't tell from your photos whether it was the Webasto or Eiberspacher burner, but it looks like your exhaust pipe is missing. At least you have it. It can be brought back to life.

Andy (my trucker brother) may have been wrong about the fuel consumption, I have no basis of evaluation there. And I don't think he has one in his Pete so he may be biased.

Up front, the lower square bit is a timer and turns the burner on. The upper unit with the knob? I've been trying to sort that out. Now the square button on the front of your shifter console is the left hand air intake control which feeds the main HVAC return through a big round hose and a butterfly damper in a square box up in the spare tire well. The right hand air intake feeds the dash air system via a long horizontal damper below the heater/AC core which has a cable attached to it. That cable goes down into the spare tire well and connects to??? Mine is cut off.

So I *suspect* your cable goes to an actuator of some sort and is wired to the module above the timer so that when you adjust the knob it opens and closes the dashboard fresh air damper. So a separate system from the webasto.

Btw, my timer was intermittent and is not the best sort of a control for RV use anyway. You can jumper two of the 3 wires to turn it on, I forget which ones but it's posted on here on my thread having to do with that. I substituted an thermostat that I bought on ebay for about ten bucks. I think I will keep looking for one that is the right size to fit in the square dashboard hole to the right of the steering column and is unused on my bus. I removed the wart that holds the timer. Currently I'm thinking of retroffitting the dash damper with a cable control which is about  $60 part.

JC, go inside to the back of your bus on the right side and pull the long access panel on the step. That gives you great access to the burner.

Here's my thermostat thread:
https://www.busconversionmagazine.com/forum/index.php?topic=33790.0

On page 2 is a photo of the unknown controller.

I think this is the last Eberspaecher thread:
https://www.busconversionmagazine.com/forum/index.php?topic=33742.0

And I think this is where it starts. Photos of the Esper round timer on page 1 and photos of the burner scattered within. Should at least help you identify things and I did a teardown and cleanup of the burner as well as a wiring check. Should be enough to get you started.
https://www.busconversionmagazine.com/forum/index.php?topic=33702.0

What ser# is your bus? Mine's 1M8PDMPA7TP048598. If yours is after that it should have the Eberspaecher. 80K btu. 13+tons of OTR A/C. Comfy!

I would still like to see how you routed your intake and filter because I think the DL3 has the same dumb intake above the radiator.  I will let you know if I part it out.  I would like to put the sides and Windows back in and sell it as a whole, but if I get no takers I will part it out.

looking at the 2 pics . that looks like a booster fan inline ( sort of )
is there power running to it and if so there should be a switch some where ?
the fresh air vent on my 102c3 was in the front tire compartment and was activated by way of a air switch in the trans. shift tower .

These pics are not of a stock install.

Someone's attempt to get more coach HVAC air to get past the wheelchair door?

Half @$# that rig, instead of buying the right seals, blocked off the stock air path?

interesting if it was effective?

I'm not sure what it needs.  It's disconnected at the moment so my assumption is the PO disconnected it due to it's condition.  Perhaps pulling it out and bench testing it would be a good idea.

Those of you who have a MCI 102Dl3, do you have Jakes for your series 60?  If so, do you know what model you have?  I heard that not all series 60 jakes will work.  Can you all enlighten me?

Your engine uses the 765A but you need to raise the floor for the install on rear MCI D never came with Jakes on all 6 cylinders so it requires some modification. I have Jakes on all 6 cylinders

765A are the old style jake heads MCI used on models with jakes on 4 cylinders. His model engine should use the 790B 3 cylinder jake heads if he wants jakes on all 6 cylinders.

Yes i i suppose he could use the 765A if he wants 3 stage jakes...select between 2, 4 ,or 6 cylinders. For 2 stage I would use the 790B to select 3 or 6 cylinders. 2 stage jakes with the 765A would be select 2 or 6, or 4 and 6 cylinders. I have the 790B on mine with 2 stage and it works very well.

Thats no joke there. I had jakes on the old 8v71 (you had a hand in that one) and my previous engine 11.1 series 60 on low (2 cylinder jakes) had more stopping power than the 8v71 on full blast. Full jakes on the 12.7 almost pulls you out of your seat. Me likey.

If your standing at the back, they will cause you to run or fall forward until you grab on something...
Don't ask me how I know :P :-[
