Look on page 230 for Newell info.

Interestingly enough, the catalog shows the IFS 84 was used on Country Coaches, Monacos, Foretravel, and some Prevost. 

I am going to do some investigation to see if Prevost has parts.

Now whether or not, you could actually buy parts is a different question.

Four years ago while on a Coach vacation, I started to experience a significant handling problem with my Newell.

Last week we completed a trip to Breckenridge Colorado from our home in Bentonville Arkansas.

The Coach performed well in the Rocky Mountains AND handled almost perfect. Almost…. More to come…

Here’s my recipe for success in a nutshell but it has been a steep and long learning curve involving many people and $$$$$.

1) ZF RAS Pressure Accumulator - That’s where my problems started. The diaphragm in the accumulator failed, the accumulator is only good for ten years if you’re lucky. When this happens, the TAG axle literally trails and is not held in the straight forward position for straight forward driving. The hydraulic pressure accumulator is responsible for holding the TAG axle straight forward when the steering wheel/steering axle is straight forward and within 5° left or right of center. I also set my ZF RAS system/accumulator to the ZF recommended pressure values of 10 bar nitrogen and 15 bar hydraulic. The system has been “bled” multiple times…. I have my opinion on that process and have probably posted that as well. It’s part of the secret recipe for success with the ZF RAS System. In the future I will accomplish additional modifications to my ZF RAS hydraulic lines and will post everything. Getting as much air out of the system is key to proper functionality.

2) TRAVEL HEIGHT ACCURACY- The Coach must be at the correct travel height front and rear, 11 1/4” on mine. The Steer Axle has one Height Control Valve (HCV) and the Drive Axle has two independent HCVs for each side. The Travel Height accuracy is critical for a proper ALL WHEEL ALIGNMENT on your Coach. If the Travel Height isn’t accurate and CONSISTENT, your bus WILL NOT driver/handle properly. I replaced all three HCVs in 2021 and didn’t realize the Steer Axle HCV was faulty until this year. I not only replaced the HCV but also reengineered the Steer Axle HCV actuating system. I’ve posted about it on this forum.

3) REPLACE ALL WORN ZF SUSPENSION COMPONENTS - I have replaced, or one could say, refurbished nearly all of my suspension. Some by necessity and some by desperation to make my Newell Great Again… Get to know your ZF Suspension. I’ve provided everything you need to know on this thread and probably in a few others. If you don’t know, you can’t grease any of the “ball joint” components.

4) ALL WHEEL ALIGNMENT - I could count the numerous times I’ve had my Newell aligned but it wasn’t until I took it to
Bill Rajewski in Columbia Missouri with Perry Legend Collision Center (573-442-7883) that the Coach drove properly. I’ve posted about this as well. Bill knows his business and knows how to make a vehicle roll straight down the highway. Trust me on this one because I guarantee you will not be disappointed.
Richard taught me the old fashioned way of aligning a Newell using string, plum bobs, math, and your noggin. He set me off on the right course but I simply didn’t have the right environment or time to complete the process. I’m sure Richard has posted his process.

5) Last but not least…. and this is my opinion… the Hydraulic System (not the ZF RAS system which is a stand alone closed loop system). My Coach has one little VICKERS V20 engine driven hydraulic pimp that “services” two critical components on the Newell, Steering Gearbox and Cooling Fan Motor. As I said, in my not so humble opinion, this setup is a loosing battle in the need for the ZF Gearbox to “function” properly and to have enough hydraulic pump to turn that Big Ass Fan that sucks air through your Radiator, Charge Air Cooler, and Hydraulic Fluid Cooler… not to mention force unneeded hot air out of the engine compartment.
In addition to the short list I’ve posted, I’m modifying my system to provide the ZF Gearbox it’s own private hydraulic pump the engine driven VICKERS V-20. I’m ADDING an Allison 4000 PTO driven large EATON/DANFOS hydraulic pump for the cooling fan hydraulic motor. Dedicated pumps for dedicated systems. Once I’m done, the ZF Gearbox will never be starved of hydraulic pressure or flow because it shared a system with one pump. Additionally… and this is YUGE…. The cooling fan can/will be properly pitched for proper airflow through the Radiator/CAC/Cooler stack. I’ll post about this as well.


So there you go. That’s what I know as of today. “Learn as we Go… Grow as we Learn”… it’s what I tell my pilots that report to me…

I hope what I’ve learned will be a fast track to success for others. Learn from my experiences and mistakes so to speak…


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Read the Original Post Below ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I’ve collected the following information using the ZF Data Plates on our 2005. The coach was built in 2004 as unit #744. I have no idea how long Newell used the ZF RL-85 suspension and drive train. The Drive Axle has a different designation (A-132/S-91/PP 476774).

Steer Axle Data Plates were located on the left and right steering hubs. 
Steer Tag Axle Data Plate was located on the aft side of the horizontal beam, left of centerline. 
Drive Axle Data Plate was located on the left driveshaft tube facing aft. The differential has its own data plate mounted on the housing.

Data plates may be difficult to see due road grime, they may have been covered by tape when the undercarriage was painted black. I used simple green HD to clean off the areas where the data plates are mounted. Note: Simple Green HD should not corroded metal parts. 

I worked with ZF technical customer service to identify the part numbers listed below. They provided me with diagrams and parts list which I’m also posting. ZF is a enormous German company that manufactures and supplies several lines of motor vehicle equipment. Maneuvering within their system is at first overwhelming and frustrating. I have requested from ZF availability and prices for the parts listed below. I will update information as it becomes available.

The following document covers several different types of ZF Servocom systems including the RAS, REAR AXLE STEERING. I urge every ZF owner to study the system so you have a solid understanding how your Active Steerable Tag system functions. It requires ANNUAL inspections and maintenance. There is a pressure accumulator that should be served annually and replaced after 10 years of service. 
Pressure accumulators in the ZF RAS look like a small metal soccer ball mounted in the frame between the drive and tag axle. The accumulator is pressurized with nitrogen and works in conjunction with the RAS closed loop hydraulic system pressurized to 250 psi. 
The nitrogen side of the accumulator can experience micro leaking of the valves used for testing and servicing. If the pressure in your tag system is not correct you may experience anomalies during operation. There is a pressure sensor installed in the system that is activated at or below 230 psi and turns a light on at the drivers position warning of low pressure situation. 
Low pressure in a tag system will manifest while backing up and the tag tires my not move in the correct direction. If the tag pressure is low enough the tires will turn in the wrong direction and backing up is impossible. Don’t force it!

Time in service is a limiting factor in these steering parts. Keep in mind the coach may have low mileage but time is an enemy to any of these parts. They live in a hostile environment far below the driver’s seat. The tie rod ends have rubber boots designed to protect the inner workings of these parts. If the boot is damaged in any way, the world of road grime and nature’s elements have an open door to enter and degrade the performance of these critical steering parts.]]>

Yea. Ready to go. Headed to Nova Scotia from Abilene. Terrible brakes. The upside is that it reminds you to look farther down the road, keep Jake ready and ensure that your personal gastrointestinal evacuation is up to date.

Hard stop (ok, Attempt at hard stop) required huge brake pedal pressure. Locked up tag disk. Still missed the turn, yet had an opportunity to replace tag tires due to huge flat spots. 

After 5,000 or so miles, back in Abilene. Brakes getting less effective. Had to go to Houston. Great practice driving in heavy traffic with small amounts of braking. PS, front began providing all the work and producing stink bombs and heat to indicate their efforts. DS taking a break.

Now my request: The Rockwell ABS discs, as described by my mechanic, utilize a standard brake air piston actuator, then through a concentric arm (similar to drum actuators) push on an acme screw to transmit pressure to the brake pads. Supposedly, this was an older approach utilized on heavy aircraft brakes. 

In other words, these do not utilize air caliper assemblies. 

I am taking in for another inspection, Monday. 

Any comments would be greatly appreciated.]]>
Yea. Ready to go. Headed to Nova Scotia from Abilene. Terrible brakes. The upside is that it reminds you to look farther down the road, keep Jake ready and ensure that your personal gastrointestinal evacuation is up to date.

I need to back up a little to explain this. When I picked up this coach I noticed the air pressure on the dash showed around 90 psi after running for several minutes. I found a line that came from under the dash connected to the brake switch "parking plunger" that was leaking or regulating I'm not sure. I found a new one and replaced it now the line maybe a waste pressure release port. Currently it is not leaking or regulating and the line pressure is running around 120-128 psi. I replaced the unit with the same number, also looks identical.
This has caused the rear of the coach to sit higher then it originally did. Looks a little too high to me. 
I can adjust the regulator on the engine mounted belt drive compressor, however it doesn't go much lower then 120 psi. 

This has Firestone air springs quantity = 4.  Two on each side front and rear or the axle mounts. The front suspension is standard leaf springs no air springs. I also plan on inspecting the rear bars/arms the rear air springs and shocks attach to. My thinking was to get it cribbed up with wood blocks and 20 ton jack stands then get up close and personal with the rear axle and air springs.

This coach also does not have a leveling system when parked. They may have used ramps or wood to level it, not sure. I did run across someone selling a hydraulic 4 shock/strut system. Looking underneath I'm not sure how you'd mount it. My crazy idea was to use the rear air springs with a aux 12v air pump. 

I suspect I either need to adjust or replace a pressure regulator for the rear air springs. I've done some searching online, but really have not found anything that gives a range for this setup. I've not called Newell yet. since it's such an old unit, I thought I'd ask here first to see if anyone has any thoughts.

Thanks in advance.]]>
