We have been intermittent problems getting #2 Slide to retract (come in).  Finally went to Newell and had 4 leaks in the hydraulics repaired, however, the slide would still not retract.  Newell said that had to go to HWH for electronic board repair. Have appointment Thursday this week. (9/6/18). Will report after this visit.

668 has been for sale at MOT for about a year. I’ve been giving some thought
To trading for this coach

Does anyone know anything about the history of this coach

A Foretravel Forum member has a unique basement A/C system on his older coach.  His board is fried such that a board rebuilder has pronounced it un-repairable.

The following was posted in response to his request for help and ideas.  Hope you all will find it interesting if not indeed helpful.

"Tyler, I owned a commercial HVAC company for years. We serviced transport refrigeration as well. I am (unfortunately) very familiar with overly complicated control circuits.  

Basic AC systems are very simple. First, the components have to work; meaning the compressor has to run and compress the refrigerant, the condenser fan (outside) has to run and move air, and the evaporator fan (inside) has to run and move air. The compressor will have capacitor and/or a potential relay that will fail. The fan motor may have one as well. These can and should be checked and replaced if needed. I usually replace them anyway since the get weak with age, are inexpensive, and will fail at the most inopportune time.  

Next you need a control circuit. The simple circuit is a contactor (relay) to actually connect 120V to the components upon demand, and a thermostat to control to contactor. Typically, the compressor and the condenser fan are controlled by one contactor and the evaporator fan by a second one. This allows the evaporator fan to be on for circulation without cooling. 

In your case, I would buy one double pole 20 amp contactor for compressor and condenser fan, one single pole 20 amp contactor for second compressor, and one single pole 20 amp contactor for evaporator fan. All should have 12V coils (for control voltage). You then need a 2 stage cooling battery powered digital thermostat. You will have to pick up 12V to power the control voltage circuit. You have the original wiring schematics so that should not be a problem. Once installed, you have a simple control circuit with readily available components.

TOM"

I didn’t want to post this here but I have searched the site and cannot find a reference to the 5” alternator pulley...  Please post if you have the number.  My coach has the Alternator, A/C compressor and Engine takeoff (water pump) all on a double belt system...  it is eating belts like crazy...

Anyone knows what year Newell started making their coaches with new emission standards? My understanding is Cat and cummins started in 2005 or 2006 .. Am i even close?

New Newell owner, so these might be stupid quesions.  What is an HPV valve?  What is a "6 pack".  All of a sudden my coach won't get past 90 lbs. and drops to 70 lbs. after a bit.  Needless to say the bags don't inflate.  I had a semi truck repair guru tell me he thoght I have a blown air bag, does that sound reasonable?  I replaced the governer and unloader valves in my compressor thinking it might be the compressor.....any ideas what to check next?

The all metal King of the Road HCV K870020 (right hand arm) is a kit from Dayton  (800-831-1893) made specifically for the Newell coaches. Richard and the engineer at Dayton collaborated on our needs and came up with the kit. Our old plastic Ridewell HCV's have two ports on each side to send air to the L and R front bags and at the top is the supply air port from the compressor. Instead of three ports, the KOR has two. The tee will go into the upper port and the supply air into the lower port. The adjustable arm going down to the lower bracket is K861004.

I'm eyeing a bus that looks very similar to a Newell but it's not a pusher and the headlights/running lights are slightly different. I've had zero luck finding any info. Any experts/historians in the group? Supposedly made by Columbus Cruiser Mfg in Columbus, OH. 1970 motorhome on a 31' chassis with Ford 330 v8 engine.

Anyone know where the fuse is located to the cruise control?
I’ve looked but can’t find it.
