Ride Height adjusters

1989 Country Coach Concept

She be leaning to the left... a lot. Here's a picture of the levelers. This is the rear, left leveler. The previous owner fabricated the nylon circles you see (I believe) and thus modified the thing. Am I right in thinking this?
What I'd like to know is the vertical rod and it's attachment points the way it's supposed to be? I want to bring this back to stock and fix the bent rod and get the leaning straight.


If I'm leaving out any other pertinent info please ask and I'll oblige.
Oh.. I checked and checked (without removing the valve assy) to find a Manufacturer of this thing... No dice.

thx for reading... hope to hear from yas!
Jeff

Easy looks bent, needs to be straight.


Take 2 adjustable wrenches and set them to just fit the from, then use them to bend it straight

We posted her on how to repair and adjust, read other position in this Forum.

I suppose I should've mentioned that, yes, I realize the rod is bent. However just straightening the rod (or getting a new one) doesn't fix the problem of 'why' it bent in the first place. It will bend again. That's all beside the point of the post.
I'm wondering if anyone recognizes the valve assembly (no name appears on it easily) and knows if the nylon circles and rod part are even close to stock-looking? I want to bring it back to stock so it's proper. So knowing the factory length of rod would be nice too.

thx

Find an identical setup on another coach and compare with yours. Then take pictures and measure the rod length and to from there. I doubt there will be many on here who really knows that much detail on what you are asking.

If the air bags leak down too much and if there are no frame bumper stops the distance between the valve and the rod on frame attachment point may be decreased to less than the length of the rod causing it to bend since it is the weakest link. The rod looks like it could be stock but generic air leveling valve rods will also work. They can be purchased at large truck parts houses.

I know nothing about Ride Height adjusters or the linkage in your photo.

But I found a picture of a Haldex valve that seems to mirror the one mounted on your rig.

Maybe this is a possible starting point for your research?

All country coachs have there own ride hight. It is very important for many reasons. Until you find this out measure the other side. straighten the bent rod and adjust the length to match.You should be able to let the air out of the bags without bending or hurting any thing. Iam wondering if some thing may have come off the road and bent the rod. good luck REX

easier to type on a real computer vs phone...

From the photo is clearly looks like something hit it.

The air springs have built in bumpers, they are designed to support the load with zero air.

As such, it is normal for the control to be at the normal lower limit for extended periods of time.

The leveling system dumps the air before leveling so it is expected to squat on this.

These are a pain in the rear to work on as they were the first parts installed.

Using the levelers get the coach high enoug to get under it to work.

Jack stands if you got them but the levelers will do just fine, make sure your helper keeps everyone away from any controls and keep your arms and hands clear of any moving suspension parts.

Remove the rod then get it straight, it is not a load bearing part nor is it precise, so get it as straight as reasonable, then reassemble.

Lower the coach back to ground level.

Adjustment is simple, confirm the ride height, CC could provide, otherwise, start the engine and let the coach come upto ride height.

Manually deploy the jacks until they JUST TOUCH the ground.

Now measure the "good side", easy way is to get a dowell and cut it to length to fit from the frame rail to the ground.

Now have a helper lift the bad side with the jack, one touch at a time until it is the same as the other side, use the stick as a guide, and be sure to touch the same distance from the axle on both sides.

Next, look at your photo, there is a nut towards the right end of the green thing, loosen this to allow the green part to rotate.

Next look for a hole where a pin can be inserted, usually 1/4 inch but could be smaller, this pin will set the green part in one position, this is the "off" position.

After it is set, tighten the nut above and remove the pin.

This should get you where you need to be, retract the jacks and start the engine, it should be close.

I have another thread in this forum that gives more details on repairs and adjustments of these units.

BUT it does involve some tasks that require one to be under the coach with the engine running, one must be sure the jacks are down, and blocks placed under them as needed to insure the coach cannot squat on you.

Adjusting these with the engine running can get it exact, but one needs to insure the coach cannot go to full squat as that is risky.

Here is the location of instructions for fine tuning of the leveler.

What happens in the valve is the action wears the tops of the internal parts.

They are designed to be adjusted out, this will provide some instructions, it may or may not work on your valve, but it looks close to ours being same year.

We have a 2006 Country Coach Allure, it leans to the right which is noticeable from the back while following the coach, not to mention our pocket doors and drawers slide open toward that side while parked. How can we level the coach, we level only on airbags (no jacks). Jim

Jim

My CC has three ride height valves. One in front and one on each side in the rear.

My chassis manual provides the ride height measurement required for my suspension.

If you are traveling with out of tolerance ride height, you could experience drive shaft damage.

So you need to get a shop to restore the correct ride height or fix the air bag that may be causing your rig to lean enroute.
