I need to find 2 to 12 new MAC air valves #225B-601BAAA for our 1984 Newell. Can anyone recommend a good source at a good price?

  8V92 airbox drains
Posted by: Tf175 - 6 hours ago - Forum: Drivetrain - Replies (1)

Our airbox drains route into a catch can which has a radiator style drain cock . I have opened this drain a couple of times , didn't see more than a drop come out . Assumed the drain must be plugged . On the trip to Ohio this past weekend I saw elevated engine temps , especially on the return leg causing me to limit speed to 45 at times on level road . Needle was at 210 a lot , sometimes going above 210/215 but never to 230 . I will post more about this in appropriate place . 
Back to the airbox , I was concerned about the high temps hurting the engine so was looking for coolant in the wrong places . Oil dipstick shows no sign or smell of coolant ( I know it should be analyzed) , exhaust looks good . Rad full . Unscrewed the drain cock completely from the airbox drain catch can , nothing came out . Removed hose at check valve , nothing . Removed check valve , it rattles , works as it should . Nothing came out of pipe from air box . 
From what I have read , Detroit  two stroke " slobber tubes " are known to drool fuel/oil . Just wondering what others have experienced before I pursue this further .
Thanks ,

  May be traveling to Oklahoma... tour the Newell Factory?
Posted by: Burlyman - Yesterday, 08:02 PM - Forum: General - Replies (2)

I am looking at some different properties to purchase and may be traveling from Oregon to Oklahoma and possibly Texas in the next few weeks to view the area.  The factory is about 90 minutes from Tulsa and about 3 hours from Oklahoma City... do I take the drive and tour the factory?  I'm guessing most of you will say yes, but I know I cannot afford new or even new-ish.  Budget will probably put me in a 15 - 20 year old coach.  Am I putting myself into a position of coach-envy?  When I buy, I dont really want to compare my "new to me" coach with the coaches I saw at the factory.  It would be an unfair comparison.   Would love your feedback.

  Vacuum pump for slide seals
Posted by: Wardworks - 07-16-2019, 07:59 AM - Forum: Slides - No Replies


I just wanted to say thank you!

I read all of the horror stories on the forum about the slide seals and thought I made a mistake purchasing a coach with slides.

We went on a trip last week and when we arrived at our destination and started extending the slides, the drivers side bedroom slide seal got pinched at the bottom and started coming out. I was outside watching for this because I have been so paranoid about it happening, I immediately told my wife to stop extending the slide!!! So after about 10 minutes of carefully getting it un-pinched and pushing it back in I told her we have to try the vacuum pumps to see if we can keep this from happening. We got lucky, it didn't hurt the seal or pull it out of the loom. That same day I ordered the pumps and the factory pigtails on Amazon and they were here when we got back. I followed all of the steps that you Gurus had documented on how to install them and it only took me about an hour to complete the job on all 3 slides. 

Now the moment of truth to see if they really make that much difference. I can honestly say that I'm amazed! Once the vacuum pump stops the seals are completely flat and away from the slide surface. Even though there is only about a 1/4" gap at the bottom of the slide that did this, I could see the carpet inside the room and not the seal, it was completely below the metal edge!

I also timed them and it takes right at 60 seconds on the bedroom slides and a minute 10 seconds on the Salon slide for the vacuum pumps to shut off after the yellow light is on solid. So for anybody that does this conversion, make sure you wait at least that long before extending or retracting the slide.

I can honestly say if you do not have this conversion on your coach, do it now! You wont be sorry.

Thanks again Gurus for paving the path to making these coaches just a little better!

  Stone Bennett shifter
Posted by: Tf175 - 07-14-2019, 04:59 PM - Forum: Drivetrain - Replies (5)

Our '86 has an Allison four speed with Stone Bennett shifter , hydraulically activated. Started having an intermittent problem shifting from neutral to drive during a 700 mile trip Friday . Twice it also would not go into neutral from drive , so I had to manually move the lever at the trans . Problem seemed to worsen as the day got hotter .
I can't see anything obvious at the trans shifter station , and the toggle shows voltage on outputs when moved forward and back . The shifter has an accumulator which has a Schrader valve on it . I am wondering if this should have air pressure . It seems like it should , but I want to be sure before trying to add air . Trans shifts fine , no slippage .
Anyone have any info on these shifters ?
Thanks , Chris

  Entry Door Skin Re-bonding
Posted by: Latitude 28 - 07-14-2019, 09:48 AM - Forum: General Repair - Replies (5)

My entry door's skin had de-laminated which caused the door to drag on the sill.  It was twisted enough that the top aft corner stuck out past the drip rail.....approximately an inch.  I had been putting it off as I dreaded the VHB tape removal process.

I picked up some 3M spray adhesive remover and a 3M adhesive eraser wheel.  Removed the door and set it up on the work bench....known to be flat and level.  After getting the outer skin removed from the door I cut down the thickness of the VHB as much as I could with a razor window scraper (the wide bladed, long handle variety).  Using the wheel (in an electric drill) and adhesive remover I was able to clean the VHB from the door and skin at at rate of 12 linear inches per minute....yeah!

The interior skin is still intact so I left it alone, but did check squareness and twist.  Corrected a slight warp with a shim under the low corner.  Roughed up the bond line with a coarse grit sanding disc cleaned with solvent.   Used Sika 252 as I had on hand and the specs (shear, tensil and elongation) are better than the VHB.  Clamped the skin with light pressure and caul blocks so as not to squeeze out to much adhesive.

Happy to report the door is hung is square in the opening and pretty much fits flush all the way around.  Closes with a thunk and opens so easy.....wife is happy life is good:-)

  Average mileage of different engine setups
Posted by: Burlyman - 07-13-2019, 10:39 AM - Forum: Discussion about what to consider on buying a used Newell - Replies (12)

As I am searching for my first Newell, I see that the older models typically had the 2 stroke 8v92 and then they advanced to the DD S60.  My dad was a charter bus driver for 20 years and raved about the Series 60 when his buses had those for a powerplant.   I see that Newell had some CAT C12, C13 and then stepped up  to the big 625hp CAT C15 before arriving at the Cummins ISX 650.

I have heard that 8v92 drivers experience around 5mpg while Series 60 approaches 8mpg.  I am not sure if this is universally agreed on, and I know precious little of the other platforms.  My guess would be that the C12/13s would be closer to the S60 while the C15/ISX650 would be more around 5mpg.

Would love to hear some real world feedback.  Budget will likely put me in a coach with the S60 or a C12/13, so if you have feedback on these platforms, I'd be glad to receive your knowledge.

  Phneumatic whiper moving slowly
Posted by: newell83 - 07-12-2019, 02:59 PM - Forum: Air Operated Systems and Leaks - Replies (6)

We have a 1983 Newell with pneumatic windshield wipers. One of the wipers is moving slow and not at times at times. The other wiper works fine. Any suggestions regarding repairing it? We are about to take the assembly out, but am looking for thoughts from anyone who has fixed a similar problem. We are aware that a replacement of the total assembly is costly, so are hoping we can fix it.

  I'm New. Need Your Advice
Posted by: RodneyNielsen - 07-09-2019, 09:16 PM - Forum: Please introduce yourself - Replies (1)

Greetings! I'm new the forum and am very strongly considering jumping into purchasing a 2007 P2000i Newell. I am requesting your wisdom. This would be my 1st Newell. I would like to purchase a newer model, but feel most comfortable with the 2007-2008 price-point. This particular unit appears to be very clean and the floor plan speaks to my wife and I. It is a one owner rig that I'm told was serviced at the factory each year. It was stored in the garage and has low miles. 

Does anyone know this rig?

Any information/advice/history would be appreciated. 

I appreciate any wisdom you could give me regarding this unit.
