Its not the dryer, I can see the dryer, but I don’t know from where yet.

I am new to these and would like to understand how they work. I have the units in my bay and I think these can operate them on and off remotely right? I just don’t want to assume and mess something up.

Thanks

Richard

I seem to have recently developed that same issue on my 89 Marathon on my trip to NC as well. When I noticed it, my left rear was leaning too low. I pulled over and it was spitting air every 4 or 5 seconds behind the tires / drive axle. I put the selector in level low on the side and raised it up, but when I went back to normal, the bus…

Hmm, I will call a local glass place tomorrow.. And yes, it has the cord in the center of the gasket.

Thank you

I don’t mind the fridge part, and I have strong bodies, I just don’t know the windshield side of it.

Is there anything I need to be aware of on that part? I can’t leave it open once the removal and change out is started.

Thankk you, I will contact them on Monday

I am having to replace my fridge in my 89 Marathon. I am in Mooresville, NC and was wondering who I can contact and / or how this is typically accomplished? I have read that one side of the windshield has to be removed to get the old out and the new back in, then the windshield is re-installed. My question surrounds types of services y’all…

Well, I made it to my destination without my alternator connected. I ran during the days, then charged my batteries overnight maintaining proper voltage. I plan on removing my alternator and having it tested / fixed.

Thanks for the info

I measured the voltage with the bus off, it is 27. I measured the voltage on high idle; it is 40.

I have a pos, neg, and field connection on my regulator, I take it that I can safely remove the field wire, and if it stops overcharging, I can connect a battery charger to the start batteries to recharge them by using my generator? Do I have to…

OK will do

My reply came back to me for some reason.

The gauge is maxed out going down the road, and the batteries are venting acid.

How do I isolate and find out which component to fix or replace? Or how can I prevent overcharging long enough to get it to the shop? My altenator on my 8V-92 is internal, otherwise, I would remove the belt.

I am not in the best position with location or time to fix if extensive.

Please help… Thank you

Richard

When you did the replacement, what o-rings did you change out on the CruiseAir? I am just trying to get a heads up on where to access. I know the schrader valves need to be replaced, but do I need to take other lines apart elsewhere?

Thank you

Richard

Thank you Bill

Oh ok, thank you

Richard

Alex,

Bearing play is good. Tires are almost brand new and have no noticable wear.

Thank you

Richard

I recently bought a Marathon coach and one of the a/c’s are needing a charge, but I don’t know what freon is in it? Can someone guide me here please?

Thanks

Richard

What does the Steering Stabilizer
Cylinder do? I am trying to track down a steering shake amplified when I apply the brakes at highway speed. Its not brake issue, it feels like a steering issue. It sounds like the steering dampner, but I wanted to dig into it a little deeper with the experts here.

Richard

Thanks Mike.

So if there are systems live, even though all switches are off or idle, the batteries are being used? Therefore, if the bus is stored for a month or so, I need power connected?

Thanks

Richard

I have recently obtained a well cared for 1989 Marathon, but the house batteries were dead from sitting for five years after the owner passed away. It has an 8 battery setup, I replaced the batteries, triple checked and marked all of the connections before and verified afterward. I am getting 12 / 24 volts where I am supposed to be getting it.…

Hi Jerry,

OK, I will get it up on ramps, check all of my connections, and test the ride height valve. I haven’t gotten under it much until lately due to the warnings and it is so close to the ground. Even with backups to supports, I am still uncomfortable. I will purchase some 2×12’s and make some ramps.

Thank you

Richard

Hi Bill,

When my bus is in auto level (Road) mode, the front bags fully inflate now instead of stopping at normal height. The only way to adjust the front back down to level is switch to level low so I can manually adjust the air. That is how my system is set up to operate. The selector you are referring to is a later version than mine, I have…

I know I have posted several things on this subject with different phases of trying to get my front airbag system operating properly, so in advance thank you for your patience and feedback.

I installed (replaced) a front solenoid that was DOA that is responsible for filling the front airbags through the ride height valve when the key is on,…

Thanks Mike, I appreciate the feedback. You were right, I called Prevost and got the standard bay door struts very reasonable from them.

Richard

Thanks Mike, I just figured they were pretty standard for our coaches and someone had a particular source already to reduce my research.

Richard

Does anyone have a source for bay door supports? A couple of mine are starting to get weak and need replacing.

Thanks

Richard

Disregard my question, I was studying the operation, and figured out how it operates… it would have bit me LOL…

Richard

Good evening Chad, Now that I have spent several weeks tracking, researching, and talking to Prevost and Liberty, I finally understand the level low and air systems on our vintage coach. I am going to reference the picture on the right you attached for me earlier talking about the ride valve and cut wires on the other valve. Where the wires…

Thank you Chad, valuable information. I took the non-working valve apart as best I could to understand some of the inners, it actually came apart and exposed the orifice that I guess opens and closes the air flow?? I have attempted to remove the orifice, but it seems to be stuck. I have found another used valve to replace it with for now,…

Thank you Chad. Just for clarification, do you mean change the guts out on the skinner valve? If so, I don’t mind doing that as an option as it would make available parts I have not yet been able to find. I will also look into your other suggestion of a possible later Norgren as well.

Thanks again.

Richard

Hi Chad,

I found the skinner valve that controls the from height control valve and its faulty, it is an original prevost part. I called them and they looked it up, but didn’t have it in stock anywhere in their system and stated it would be a 90 day delay in delivery…… They did give me the brand and part number, and I have done some looking,…

Well, I didn’t get any responses, but through continued examination and creative methods of introducing isolation air, I did find my issue, so I thought I would post in case it would help someone else that may experience the same type of dilemma.

Applying air through the level low valve could not deliver enough volume to the front airbags and…

I have been chasing several air issues since returning home from work. After chasing and repairing a couple of other air issues with the help of several on this site (Thank you), I have now gotten myself in somewhat of a pickle. The front airbags would not raise automatically, but they would raise by way of the front level low push button at…

Just let me know when you get home and I will call and talk to you about my coach and your product.

Thank you Ted

How is it applied, what do I need, and how much is the product?

Thank you

Richard

OK, I will get some uploaded. I have attached my air schematic supplying the front air bags through the driver’s level low control valve as well as the supply air to the height control arm. I only see two areas of possibility within that system if it follows the air schematic, both have to be physically located. (1) A pressure safety switch at…

Chad,

I have looked all over the compartment and don’t see the pictured skinner valves. If I am tracing correctly, I think the level low system is intact?? But, I originally installed a level valve to correct the original problem of auto lift, but the new part didnt make a difference, I still have to manually charge the front bags with the…

Thanks Jerry, I tried the tech section. I even clicked on the “older” archive tab, but I couldn’t pull up my year including using my VIN. I will contact them direct to see if there is any other option.

Richard

OK thank you Chad. I will make another thorough round at looking for them and let you know what I find.

I appreciate it.

Richard

Thank you Chad, valuable information. I am looking for the solenoids you have in your first reference picture, but I haven’t located them yet. Are they located in the the front compartment close to the Air filter housing, or behind the wall nearer to the front ride height mechanism?

I am trying to locate several problematic issues with my liberty coach Prevost, but I need to have access to a service type of manual to accomplish locating or tracing the lines, accesses, etc. I have a complete parts manual, but it only shows me the parts breakdown, but not where or how they are installed. I am actively trying to locate…

What did you use to insulate the area over the driver and across the front? On mine, there is fiberglass insulation that has fallen down and is not working at all. I would like to apply spray in as a replacement, but haven’t found anything specific yet.

I look forward to your updates.

Chad,

Because you and I have the same Liberty year and model, I followed you for a long time with the same intent to remodel mine, then was away for a few years. When I returned, the site had changed hands and I lost all your posts as they didn’t move with the new site I guess. I am glad you are still on the site.

Richard

Thanks Chad, thats a nice refit. I found and ordered the old filters to get me back in service, but will get these as a soon replacement.

Richard

Thanks Jerry

I have always wanted to bring back that original glass shine to my coach, but haven’t been able to find definitive information on how its actually accomplished, and the right compound, pads, etc needed for it? Does anyone have a source for information and / or supplies that I may look up or contact? I know it would take patience and time, but…

Thank you Mike, I responded several days ago, but it didn’t go through. I ordered a set from Ebay and they are on the way. I do plan to replace the filter system to modern spin on filters the next time I am looking at filters if I can find the right equipment for the conversion?

Richard

On the schematic, they label it as an Air Filter. The filter looks like a tight woven roll of yarn.

I have been looking for a replacement filter that is part of the main air system located in the compartment under the driver. What I have run into is that the filter no longer exists and has to be replaced with an updated filter system. My question is whether someone on here knows what I need and/or has done the same conversion and has any…
