Kevin,

I'm sure it's old news, but congratulations on the bump to Moderater status. With your background in education, and willingness to help people, I know you will handle the task well.

When did you order those particular Centramatics? A year ago? Two years?

Thanks,
Tom

We had Centramatic create a different balancer.

It's part # is 200-221 Special-A

So far, we have not found anything it will not fit, old or new, as long as the bolt pattern is 6 holes on a 5 1/2 inch bolt circle.

Special wheels that someone may choose to have will not necessarily be able to use this model.

There are way too many different wheels, for a "one fits all" application.

Andy

Andy,

My ultimate desire is to have a set of Centramatic Wheel Balancers on my 1967 Airstream Overlander. As I am now apparently getting old & lazy, I simply wanted a vendor with tons of Airstream experience to sell me what my vintage Overlander needs. If shoveling extra money on the task was required, then so be it.

I started our initial discussion with email messages. Then you PMed me and said that your email to me was being blocked, and that I should call you. I then replied to your PM with both the latest news, and my disappointment that your organization did not immediately know which Centramatic product would fit my application.

You replied back to send pictures of the sort that required a whole lot of work on my part.

You then posted that Airstream never used offset wheels. In fairness, I never actually verified my wheels are offset. My Overlander was built in Ohio. Several years ago, I changed the wheels on till’s California-built, 1967 Overlander, and noticed it was much more difficult to get the wheels out of the wheel well than it is on my Overlander. Between that, and Markdoane’s posts on wheel offset, I have high confidence that the source of my trouble with Centramatic wheel balancers is due to wheel offset.

I am 99% sure I have the wheels Airstream put on this American Icon in 1967. Short of a seance, no one will ever know.

In an earlier post, you asked if I had steel or aluminum wheels. I personally find it hard to believe both were an option in 1967. My brochure does not list different wheels options. I think Andy Rogozinsky would have known that.

Inland RV Center In is a wonderful source of parts. I will continue to call the pleasant ladies at the front desk when I know what I need.

In conclusion, don’t expect any email/PM until at least Spring. If, however, Inland RV Center In should figure out which, if any, Centramatic Wheel Balancers will fit my original, Ohio-built, 1967 Airstream Overlander International, I would welcome correspondence. My VISA card is ready.

We can send you the Centramatics that fit the original wheels, not a problem.

However, if they don't fit, then simply return them.

Centramatics for Vintage?

I ordered the Centramatics in March of this year . . . as I knew that it was time for new tires and wheels for my Overlander so thought this would be an opportune time to add the Centramatics. I am hoping that I will find that these Centamatics will fit my Minuet . . . .

My Overlander's tires are now seven years old, and I would feel better replacing them before our next long-distance trip.

The wheels are now off in preparation of new rubber.

Andy - Please refresh my memory as to the dimensions you need to have in order to fit my Overlander with Centramatic wheel balancers.

Thanks,
Tom

Tom.

The back side of the wheel should have a flat surface of 9 inches, or more, for a proper fit.

My Airstream's wheels appear to have more than enough flat surface:



The time was also right to check for wheel offset:





Subtracting the two measurements, and rounding, I would say my Overlander’s wheels are offset one-half inch.

In an effort to cover all bases, a mockup of the balancer InlandRV is selling was made based on their website photo:



I believe their product will work with my offset wheels:



And with my “new” Henschen axles:



InlandRV’s product will fit my application because it is smaller than what Centramatic sells for 15-inch wheels:



The reduced diameter will affect the balancers’ ability to correct out-of-balance conditions. Is InlandRV’s product too small to be effective? I don’t know – Gotta think about this one.

Feedback from customers have been 100 percent positive regarding the effectiveness of the smaller size Centramatic.

And no, Centramatic does not have that special size in their inventory or catalog.

I agree, "BUT", it's a rarety to find a shop that can balance the tire, wheel, hub and drum, as an assembly.

So, you now can balance just the tire and wheel, and say hello to Centramatics.

Solves the issue, permanently.

After analyzing a still from a training video from Centramatic, a photo from InlandRV’s web site, and photos of the original Centramatics I bought & returned several years ago, more conclusions have been drawn about the effectiveness of the dynamic wheel balancers offered by both Centramatic & InlandRV.

While I know my analysis would have more validity with either design prints or sacrificial wheel balancers, the former was not available, and the entire topic is not important enough to purchase & butcher perfectly good balancers just to reverse engineer performance. Please accept that errors may have occurred. This is nothing but a paper exercise.

To understand what a reasonable goal was, I went out to my Airstream, and found the wheel with the most balancing weight attached to it, and sat down to figure out if the performance of InlandRV’s dynamic wheel balancer would make the weights unnecessary.

The worst-case wheel had 4 ounces (113 gram) of lead on the front side, AND 3.75 ounces (106 g) of weight on the back side (at the same location) for a total of 219 grams balancing weight mounted eight inches away from the hub’s centerline.


InlandRV’s product, with its reduced size would need to position 350.4 grams of weight at the same location to provide the same balancing result.

While I got a kick out of this entire self-imposed task, I know most people could care less about the technique & actual number crunching. I will spare you except for one image:


My analysis (as I said is not based on reliable data) indicates InlandRV’s product can only accommodate 214.5g of imbalance. This is 61.2% of the goal.

It was only fair at this point to analyze what Centramatic sells for 15 inch wheels. As the diameter of their product is 2-1/2 inches larger than InlandRV’s product, a more favorable result was expected.

Centramatic needed to provide 292 g of balancing weight on its six-inch radius to provide the same end goal. My error-prone analysis yielded only 271 grams. While better, it would only be 92.8% effective on the same wheel.

In conclusion, either balancer should be capable of correcting for imbalance in the cast-iron hub. But it appears to be prudent to balance the wheel/tire combination before depending on either product to make your Airstream’s ride more smooth.

Oh, and the perfect balancer would have measured ~13 inches in diameter.

On a seperate note not knowing anything about a Centramatic other than it's picture in this thread, I would be concerned about it's design restricting air flow for brake drum cooling. Many parts of the country this wouldn't be an issue. In AZ it gets a lil hot. But just to let you know it's a dry heat.
