A good start might be to check out Centramatic wheel balancers on ebay or amazon or visit their web site.

I have already sent them an email, but unfortunately they don't have any for my 16.5 8.25 5 lug rims.

How in the world would they ever know you put new rims and tires on it. Is the tire size tag a government supplied tag, where it could not be easily forged?


The tire size is stated in the German vehicle registration and must be shown during the annual safety inspection.

The police is also allowed to check it in the course of a traffic stop.

Any changes of the size (or on the vehicle) must be approved by the Technical Supervisory Association.

Otherwise the inspection sticker on the licence plate will be removed and the vehicle must be towed. These are the traffic regulations in Europe.

Balancemasters don' t have sets for my Revcon.

Yesterday, while my partner was driving on the German Autobahn, I went back into the bedroom to identify the source of the vibrations. It seems to be the first wheel on the Hendrickson Tandem on the passenger side.

Did the 79 Revcon come with Hendrickson axles or was that an upgrade?
At least, you probably have located the problem and can resolve a solution. Can a local machine shop check your brake drums for proper balance?

Wishing you the best of luck and appreciate your keeping us updated.

Hi TTTPHD,

I don' t know. A plan of the Tandem which was included in the files of the former owner says, that it is a "RV-84" Hendrickson Tandem.

But I went to an old tire specialist in Saxony today. He finally had the necessary equipment and took care of my vibration problem. He jacked up the Revcon and spinned the wheels with his balancing machine, while we were watching them closely.

And here is what we have found out:

The heavy vibrations come from the second wheel on the Hendrickson Tandem - passenger side. The wheel bearing has a lot of play there. It was pretty scary, watching the wheel wobbling around the center. The Transforce tire is already damaged and has got an oval outline.

The vibrations are also transfered to the first wheel on the Hendrickson Tandem, which also shows a light bearing damage. You can also hear a silent, grinding sound when slowly turning the first wheel.

The vibrations have already started to show up at lower speed. First - when I bought the coach 2 years ago - they were noticeable at 58 mph, now after 2200 miles at 55, so the damage is getting worse.

The rear wheel bearings have never been exchanged during the last 93.000 miles.

The former owner was focused on the FWD only - there, he replaced almost everything - and was not able to solve the problem in 20 years!

I have no idea where I can order the correct rear wheel bearings yet...but I finally - after 2 years of dealing with the issue - have got an reasonable explaination for the source of my problem!

The tire specialist in Saxony is also able to balance the wheels on the Revcon, as advised in the original manual.

Maybe an imbalance of the big brake drum is responsible for the heavy damaged wheel bearings - or only the bearings went bad.

However, let' s get 4 new rear wheel bearings, which fit and a new tire, of course. After that I will take care of the correct balancing.

This will take some time.

Thanks.
Matt

Congratulations! Your persistence is paying off!
I have had some success with finding bearings via the internet. I just searched bearing followed by the bearing number. In my area, the price has been less on the internet than going to a local bearing supplier.

I searched for information on your axles and found nothing.
How are the bearings lubricated? My 1984 Revcon King rear wheel bearings are lubricated in an oil bath.

Wishing for you the best of luck and happy camping!
