I don't know if this applies to the '98 Patriot or not - but for those Coaches with the HWH air leveling system, you have to have the Ignition Key On and HWH "awake" to adjust the ride height. If the HWH system is off it will not provide power to the Travel valves (they are closed) so air can't pass through them to get from the RHV to the airbag.

Just a FYI.  You will need a small box end wrench (I think it is 7/16) to loosen the nut that tightens over the adjustment slot.  Don't loosen it much, just enough to move the adjustment lever.  I would guess you are only going to move it about 1/16 of an inch to get a 1" raise on the bags.  I assume yours is like mine and has one valve in the middle of the front axle and two valves (one on each side) of the rear axle.  The rear axle valves control the side to side leveling and the front axle pivots to keep from twisting the frame.

I was just reading the instructions for ride height adjustment in the Owners manual in the Technical Library on the main BAC website.  I was reading the owners manual for a 2006 Beaver Monterey (which is what I have).  It starts on page 264 in that manual if you can't find a good description anywhere else.  (They even have pictures of the valve, which helps a bunch.)
Good luck and be careful under there.

Hi Carl, thanks for the message. I am gathering you have done this before. I have been unable to find any definitive description of the adjustment process. I assume moving the horizontal rod up increases the ride height? I am familiar with the rubber boots and the hose clamps that hold the vertical and horizontal rod assembly together. If my assumption is correct, how much adjustment would I need to make a 1" difference in the height?
Regards Richard Good.

Richard,

If you have or can make some ramps this is not a difficult job at all.  It is certainly easier than tightening the belt on the 3126 that you just did! 
 I use 3 2x10 for each ramp and that raises me up 4 1/2 inches.  I also put blocks between the two frames so it can only fall so much.  Since you need 10 inches at the air bags I would cut the blocks to 8 inches. 

You may want to examine the air valves while you are in there.  I replaced all of mine, but kept one of the old ones to use for a emergency spare.

You sound pretty mechanical so I think you will be fine if you attempt this.

Yes Richard
 the ride height is measured from the top mounting plate to the bottom mounting plate of each air bag and should be 10 inches on your coach .
Not only does it give you more ground clearance which means less draging the rear over hang but more importantly it makes for a straighter drive line angle on the drive shaft which is very short on these coaches
The ride height adjustment is fairly easy but the coach should be parked on blocks to give enough clearance for you to safely crawl under even with all the air out of the bags in case of an unexpected loss of air to one of more air bags.

Hope this helps
Eric.

Good work Richard
 I know that's a tight area to work and takes some patience

Good luck with your next project

Thanks, it have it all set to go back together but it seems the upper mount needs a metric bolt.  I found that a 1/2" bolt fit the upper hole in the alternator, but now that I bought a long enough bolt to go through both upper mounting bracket holes it seems that won't go and the bracket on the engine measures 12mm hole diameter.  It looks like I am shopping for a new bolt.  The original bolt was a 3/8" that only was in the front most hole of the upper mount, the alternator was not installed correctly when I bought it.

thanks

I am fairly sure it is the tach wire, it is the correct color and the wire number matches the Gillig original diagram.  I will ring out the wire today with a meter.  It is one of those things where it appears someone replaced the alternator and didn't really understand the correct set up.  I did not understand the DUVAC idea until I did a fair amount of reading into the matter.  The alternator that I have in my coach seems to be a knockoff, and has no markings on it except + & - on the main lugs.  I agree with what you wrote, the reason I started down this road was that the tach has not worked since I bought the coach last May and the miss-wiring makes sense from that aspect.

thanks
