  Future Newell owner

I have had a couple of older Foretravels (93 and 95) and with my new wife we decided to get another RV. Choices were another Foretravel or a Newell or Prevost. I'm never going to be a new RV owner even if I won the lotto. Unfortunately the newer Foretravels quality and design has gone down after 2005 with the new owners. Pretty quickly we decided on Newell. There was a time around 2005 when I was looking at RVs, the owner of Newell would text online, which really impressed me.
Anyway, we expect to buy a 2005 or 2006 in the next 6 to 18 months. I'm trying to stay in the $250-300K range. 2005 because they shifted over to the Cat 15 liter and especially the ZF tag axle.
I am interested in finding out which years they switched to the 12 speed trans, and the electric steering. I figure I will run across that info here...
I've slowed my texting the last few years without a motorhome - I was a Foretravel guru for about 10 years. Not sure I will ever be a Newell guru, but I'm happy to talk to some!

  Looking for advice on bathroom vent blower in classic

I have a dual fan style blower under my bathroom sink that provides exhaust from bathroom and the stove.  It is a 12 volt fan, I attached a picture.   I also attached a picture of what I think is the exact replacement but it is no longer available.  If I am correct this puts the blower at 700 cfm on 12v.  

Has anyone replaced this blower?  Did you find a replacement, rebuild the existing or did you use something different?

  S60 Jake Brake Question

- Replies (22)

After having driven a S60 with 6 speed Allison I'm a bit perplexed by something.  My understanding was that the optimal range for using the Jake was around 2000 RPM up to a safe maximum of around 2200.  When cruising along at 65 or so and heading down a long slight grade in which the coach itself will not hold itself back in 6th without either braking or the Jake the Jake wants to downshift 2 gears into 4th and that takes you to darned near 2500 RPM.  One would assume that the controller on the unit would not let the trans downshift to an unsafe RPM for the engine, but I have not seen an reference in anything I've read that it's ok to operate at that high of an RPM on a regular basis?

I can't for the life of me understand why it's programmed to drop to 4th automatically as there are so many times that a less agressive breaking would be preferred.  Would to be so much better if it either stayed in 6th initially with a slight uptick in speed triggering 5th and/or braking on top of that should make it drop to 4th.

Just bought a 1992 45ft Newell coach that needs front airbags. I have some part numbers but, want to verify they are correct before ordering? I have Goodyear # 1R11.066 or Firestone # W01-358-8992. Does anyone know if these are the correct airbag part numbers for the front of this coach? Thanks

1986 40' Classic #121 with a Perkins Diesel Generator. I need to replace the sound deadening insulation in my generator compartment as it is crumbling and falling off. Anyone have any experience with this project? What material did you use? I will likely pull the whole generator and engine out to get good access.

I am looking at purchasing #1253. It was owned by a Nascar driver. I have spoken with Newell as it had been serviced in Oklahoma during its life. This unit is in Florida and I will see it on Monday. I currently have a Newmar DP and want to make sure I am checking out this bus to make sure I know what I am getting into. I am going to have it inspected if I proceed but wanted to see if this group has some input on what to look for. I also am curious if any other Newell's  available for under 500K.

.pdf 2007 Newell Axle Weights.pdf Size: 426.78 KB  Downloads: 10


Eloy, Arizona between Tucson and Phoenix has a Travel Centers of America Truck Stop with a "CAT" certified scale. (certified by the State of Arizona).  I'd not weighed our Newell so stopped in.  The scale operator provided specific instructions and with the overall scale divided into multiple segments which could weigh each axle individually I was able to get the weights of each axle.
I had been told by a previous owner that #1202 2007 Boomer weighed 63,500. That number had recently been brought into question.  As it turns out:
Steer-18,140, Drive-23,260, Tag-13,800 totaling=55,200.  That was with about 50 gallons of water, 170 gallons of fuel, and loaded for travel.  

Now to recalculate the tire pressures based upon the data and tire manufacturer's recommendations.

  2007 brakes

Forum: Air Operated Systems and Leaks
- No Replies

winegrower was here with his 2007 4 slide steerable tag beautiful coach.  we spent some time working and learning on it.  i still no not claim to be any kind of an expert so take all of this as what i understand but may be not totally accurate.  

for a few days, we thought we had a brake problem that ended up not being one.  

i might add, that what we learned is that the system is a tad different then the one on my 2002.

his coach has both both abs and traction control.  

the problem we thought we had was found when we were working on the leveling system and supply air leaks.  

if you recall, as long as your check valves and ppv valve is working properly both your front and rear brakes should stay pressurized when you are sitting without touching the brakes for days. (on my 02).   if they both go down with the supply air pressure, then you have  bad check valve.  

that is the premise i was operating on for bobs 07.  i called richard and steve to confirm and discuss.   the problem we were having is when we would discharge air from the fill port in the rear passenger side engine compartment (we use shop air when in my shop), then several things happened that i couldnt explain.   first the supply air stayed pressurized to 60 or so and the front brakes went to ZERO and the rear brakes would go down to 75.  that is all from 125psi or so.  

in the older coaches, that would mean the ppv valve is malfunctioning and there are other threads about where to find it on the frame rail in the rear horizontal frame.  well, we looked and looked and could not find a ppv valve.  and still wondered why the supply air would stay up at 60 or so and not go down when we drained the supply (labeled accessory tank) on bobs.  

the supply pressure was easily explained.  in my 02, there is a 12v system for the potties, air door, and pocket doors.   it has its own little tank in the passenger side drive wheelwell.  and is kept isolated from the 120v and engine compressor by a check valve that allows air to come into the 12v air system but not back out.  and that is kept at 60 or below.  when i asked newell, they said there was no additional tank up front.  so that meant there was a check valve somewhere for the doors on the 07.   never found it but likely in the air things we found in a bay to the rear of the entrance door.  but at least understood

but why was the front brakes going to zero, rear staying up and why couldnt we find a ppv valve?

i ended up finding this video on youtube made by bendix.  

https://youtu.be/Mdtfly3-ogo             yes it is a safe link

when looking at all the valves and tanks on bobs 07, it matched this video.  

in the rear there is a front brake tank (secondary), a rear brake tank (primary), a brake relay valve (r14), and a front and rear abs valve (those three valves shown in the picture and were on the aft side of a horizontal frame rail above the drive wheels) a spring brake modulating valve on the back frame rail horizontally by the tags.  in addition, there was a very different looking air dryer in the drivers side tag wheel well.  the one on my 02 looks simple with a filter on it.  the one in bobs had way more on it and an air chamber as well.  ends up it is a Bendix® AD-IS®. and that is why we couldnt find the ppv valve separately.  it has the ppv valve built in it.  

i called bendix tech support (which is incredibly helpful) and they explained that the way that air dryer operates is that it will allow the front brakes to go to zero when the supply air is drained and the primary (rear) to stay up.  so it was operating the way it was supposed to.  btw,  call them about anything bendix related and they are super smart and helpful

btw, when sitting overnight or longer, with the shop air off and all tanks just topped off, the brakes will settle down to 75 and stay there.

so, the video above is exactly the setup that is on bobs 07 as i understand it.  

the only additional things are the traction control valves for each rear suspension that is fed by a 1/4 inch control line coming from some bendix controller that i assume comes into play somehow.   here is what i got from an bendix document

"controller provide an Automatic Traction Control (ATC) feature. Bendix ATC can improve vehicle traction during acceleration, and lateral stability while driving through curves. ATC utilizes Engine Torque Limiting (ETL) where the ECU communicates with the engine’s controller and/or Differential Braking (DB) where individual wheel brake applications are used to improve vehicle traction. Premium EC-60™ controllers have a drag torque control feature which reduces driven-axle wheel slip (due to driveline inertia) by communicating with the engine’s controller and increasing the engine torque."

so i dunno if the 07 has all of that or not, but something to research.

also, remember that the parking brake modulating valve keeps the parking brake (controlled by mechanical springs) off when there is high enough air pressure in the brakes (bobs seems to come on between 50 and 60 when we discharged the brake tanks).  i am sure you all know that but if your brake air pressure for any reason goes below that when you are driving, your parking brakes come on.  like it or not, ready or not.  

everyone hears about brake cans and you can see them on each wheel.  remember they can only leak air when the brakes are applied. 

thanks to those i called and bugged as i was figuring this all out.  

again,  i am no expert and i may be off in my explainations so i welcome any thoughts or additions.

  chasing air leaks on 2007

Forum: Air Operated Systems and Leaks
- Replies (9)

hi all,  

i am posting this on winegrowers 2007 coach 1202

bob and sandy came to my place and we had their beautiful 4 slide 2007 newell in my shop for the last 2 weeks.  they lived in the coach as it is quite nice inside the shop and they had full access to the bathroom and shower in my mancave.  

i will try and post simple versions of what we did and learned.  that said i will say bob had to do alot of the hard work as i am waiting to get a knee replaced soon.  i kinda hobble around    i think i probably have the only garage with a lazy boy right where we are working....ha

problem 1.     drivers side rear drops all the way overnight.   using my whisper sniffer and alot of kids bubbles in a spray bottle we found two things.   the zf suspension with steerable tag has two airbags on the drive axle and 1 on the tag.  the drive bag between the axles fitting on top of the bag was leaking.   we replaced it.   then we had to hunt for other leaks.   we used my pressure test jig to isolate each section.  we tested each airbag separately and they all held air with no leaks.   the idea is to isolate each section and eliminate it for leaks.  

the airbags for the drive axle are totally easy to get at.  can change them without taking a wheel off easy.  the one in front of the drive axle when we deflated it, separated from the top mounting plate.  the mounting plate is just setting with a bead like seal on the top of the bag.  to get it back up we took the bottom nut off that holds the bottom of the bag on, greased up the top plate and with air applied pushed the bag up, then aimed the bottom mounting plate back into the hole and walla....got it on.  we got quite good at it i must say.  

we tested from the six pack to the airbags....still a leak.  the zf suspension has traction control that puts air in or takes air out of the bags on the rear.  there is a traction control valve on each side in the rear.  the one on the drivers side was leaking.  they are unobtanium.  called bendix, and there was non in north america.  fortunately newell had two so bob had them overnighted (took 4 days).  the valves are located near the tag up on a frame rail.    fast forward to last nite and it held air up all night and no dropping.  so we fixed that.  

problem 2.  passenger side rear ride height valve was escaping air out the exhaust port all the time even when we were NOT in travel mode.  a short primer on ride height valves....avail elsewhere on the forum as well.      2 air lines on the rhv.   one is constant air in.  always air there if there is air in the system.  the line on the rhv goes directly to the six pack.  that line connects directly to the rear air bags on that side.   if the rhv calls for air (in travel mode and coach is low on that side) then in travel mode the travel solenoids are engergized and open and the air flows from the air source on the rhv to the six pack and then directly to the 3 airbags on that rear side.   if the rhv calls for air to be released because the coach is high on that side, then the bags escape air through the six pack to the rhv and exhausts out the bottom.  a note on valid leveling system is that travel mode is called select on the six pack.  

the rhv is totally accessible in front of the drive wheels on the side of the coach unlike our older ones.  

only way for air to be escaping out the exhaust port is the valve is broken, or the travel solenoid is open some or a lot.  

i had a spare rhv so we change that and tested the old one.  it was working perfectly.  so it had to be the travel solenoid (note to self....should have tried that first).  the valid six packs are different than hwh.  the valves have no valve body with orfice.  the orfice is in the six pack itself.  so you take the coil off and then take the stem out of the six pack like you would take the stem out of the valve body that on the hwh ones.   use the same spanner wrench as for the hwh valve.    bob got the passenger side travel (select) valve stem out and the orfice and plunger was all gunked up with debris.   cleaned it up, put it back in and now no flow out of the rhv.  

i learned a ton about the braking system on the 07.  it is quite different than the one on my 02.   i will write that up separately.  we thought we might have had a problem with a ppv valve on bobs, but that ended up not being the case.  

problem 3

120v compressor comes on every 5-10 minutes.   the 07 has twin 120v compressors.  you can choose to use one or the other.  they are backups to each other.  there is no 12v compressor like my 02.  

we found a bad fitting on a distribution block on top of the front six pack behind the headlight.  not much room up in their on this year coach.  we found a bad fitting on the 120v compressor distribution block.   

i found a leak on the regulator valve on the bode air entrance door.  it is behind the laminate cover.   it is a pricey little piece of plastic at 147 dollars from bode.  

we went over every square inch of the coach that we could find air fittings.  inside and out.  the only things that are air powered are the airbags for the front mounted genny, the air horns, the entrance door and the two pocket doors.  the potties are electric and so is the step cover.     the supply air drops pretty quickly.

we took off each air line on the accessory tank in the rear and pressurized them separately with my test rig.  there was one quarter inch line (all the rest were 3/8) that was leaking down fairly fast.  we thought this was the quarter inch line from the front compressor but that was not the case.  the quarter inch line from the compressor goes somewhere and converts to 3/8 then goes to the level tank and then a small line from the level tank to the accessory tank.  

using my whisper sniffer and quarts of kids bubbles led to no further discoveries.  so that mystery is for another time.  

all of this could have been days shorter with an air system schematic from newell.  but to no avail.  

i am sure i missed alot, so bob please chime in.  i know you replaced more fittings than i have mentions and you are the one who really got dirty.  good think is he spent so much time scooting around on my floor that it is pretty clean now....ha

bob is a delight to work with and it was fun having him here.  

thats all for now.
