Does anyone have or know were to by a tool to correctly place the wheel seals on the axles? Also is there anything to use to cut down on the water in the air system? Someone said alcohol.

Thanks

Most HF and Northern tool stores have the set of seal installers for 20 bucks.For the moisture if you are equipped with a drier check the wiring and service it if not it is a good investment ,good pull type drains work also but need to be done everyday when in use.Alcohol is for keeping the moisture from freezing it's not going to help with the moisture problem good luck

Moisture in the air system is from the humidity of the air sucked in and compressed.

Can't change that!

Drain the tanks more frequently to keep the puddle inside to a minimum.

install the pull cord types to make it easy.

Or install an air drier to remove most of it by remote control.

Probably best to forget about automatic drain valves, they are found by many to be great in theory, but poor performers in practice.

happy coaching!

Try these folks for wheel seal installers : http://www.spxkentmoore.com/
We had a set from National.
Here's a chart: http://www.udxtra.com/products/national/IntrchngWallChrt-0505.pdf
Hope this might help.

I won't buy a seal from a provider that can't give me an installation tool. They are always free to me, but I do buy alot of seals from the same places. You can usually come up with something to drive them if you have to. Maybe a bearing and a piece of pipe, etc.

About installing your wheel seal. It all depends which version you got. There is one with the micro-lip ring around the outer seal that only require push 0r light tapping around the seal's ring. The outer version are either vinyl coated or bare metal that can be equally hammer tap diagonally around seal with a piece of ¾" by 6 " long birch dow as a driver. When done it...should be driven all the way to the stop-limit....beyond the hub's ring edge or surface.

Photos of it would be nice to file for future information. To add to the Wiki file.

I agree about the automatic air tank drains.

Mine doesn't seem to work at all but it has a manual cord which I use.

I also have a manual drain on the front "dry tank", which isn't!!

About the amount of water in air the tank...Water or moisture come from humidly in the atmosphere. Example if you compress dry Arizona air you get very little or no moisture in the tank. If you are in Florida in very humid day...you be pumping in moisture so that air-dryer and tanks will be accumulating water until the engine/compressor shut off.

For buses safety of carrying passengers in the freezing climate season...DOT required buses to have an automatic purging dryer to help keep other tanks and line free of ice to maintain a working braking system while driving.

Alcohol system works but only with the smaller amount of moisture and hard on valve's seals and piston's "O" rings due to wash out oil coated surface to stick at times.

Are you talking about the seal in the hub, or the wiper on the axle? You said seal, but then said on the axle.

Regardless.... I install the seals by placing a large piece of 3/8" flat steel over the seal and hitting it with a rubber mallot. Drives it in evenly. Works well for me. The wipers on the axle I install by heating in the oven to about 250 - 300 degrees. I oil the axle, and then slip the wiper onto the axle and use an old bearing to repeatedly knock against the hot wiper to seat it. Like using a slide hammer in reverse. Again, works well for me.

Grumpy,

It has been a while since I did my 04, and I dont have anything apart on th 9 yet, but,

Doesnt the seal with rubber ID slide down the axel first This needs to be in correctly or it will leak.,

Then comes the race for the first bearing then the bearing, then the hub with a additional race and bearing.

If the bearings show any wear or pits I will have to replace the races both on the axle and inside the hub.

I guess Im asking for tools to use to get everything right.
