Installing Centramatic Balancers

Question on installing centramatic balancers on a 2005 Safari with 15 wheels. Are they mounted with the beaded ring facing out or in?

Thanks

Lynn

It may vary depending on your specific wheels, whether they are original or aftermarket and on their specific off-set and backspacing.

Generally, you would mount them with the bead ring facing inward so it is over the brake hub and the flat side is toward the wheel. As long as they fit without being bent by the wheel, they're fine. If they fit the other way, they'll still work the same, just make sure you're consistent on each wheel. I have them on my truck (will put them on the trailer after I replace the axles) and they make a big difference!

installing centramatic balancers

Thank you for your response! I have the original hubs, I've seen them mounted both ways but wasn't sure which way worked best.

The Centramatic wheel balancer model for Airstreams with a 15" six lug nut wheel is:

200-221 Special

The model number for five lug nut wheels like the 14" on our 23D and some older Airstreams is:

200-221

The set of four cost $199.00 plus around $20 in shipping. Sales tax is not collected in Texas.

Their phone number is :

It does not make any difference which way you mount them.

The most important thing to observe is the back surface of the wheel. It MUST NOT in any way bend the balancer.

Most all steel wheels are OK, but many mags have a convex backside, which would damage the balancer.

If you are staying with the five bolt lug nut pattern of the stock 10" drum brakes on the 23' models, then the standard Centramatic model "200-221" will work ($199.00 plus about $20 in UPS charges with no sales tax out of Texas). We purchased the SenDel T03-56545T wheels and the stock stainless steel center cap fitted just fine.

While the wheels are off, you might inquire about the cost of upgrading to self adjusting brakes (replace the backing plate assembly).

We checked the wheel bearings after driving the 23D just under 2,000 miles from the dealership (it was trucked from the factory to the dealer as was probably your unit) to the modification center and discovered that lack of sufficient grease had already scored one set of wheel bearings and the others were low on grease and had to be repacked. I installed a Timken bearing set to replace the damaged bearing.

We are replacing all four bearing sets when the upgraded self adjusting brakes are installed in May.

Four each of Timken Set #4 ($7.70) and Set #17 ($8.80) wheel bearings
Four Timken 441151 ($2.98) bearing seal (suggest a couple of spares just in case)
Ordered from Amazon for 10” brake drum and axles

There is a video at the Centramatics web site that shows how to check to make sure your Centramatics, wheels, and hubs all match.

Centramatics and Nev-R-Lube

Has anyone checked with Airstream or Dexter about the zero offset specification on the Nev-R-Lube bearings?

Specifics would be whether there is an engineering tolerance (ie., "zero equals .001-.004" or some such) that would allow installation of the Centramatics balancer on drums with these bearings.

This might be a stupid question (but someone once told me the only stupid question was the one unasked). Am I correct in would assuming that if Centramatics are installed there is no need to have the wheels balanced when new tires are mounted?

Another question, $200 plus shipping is rather expensive (not debating the merits of having your wheels balanced). Are there any other options on the market other than the traditional lead weights?

Thanks for indulging me!

I was told by Centramatics it does not matter. Either way will work. Mine did not fit facing outward, so I reversed it. No problems.

The tires still need to be properly spin balanced. The Centramatic wheel balancers have a full time job trying to balance the Chinese casting brake drums.

I even have them on my Classic's disc brake conversion as well as the Ram 2500HD tow vehicle.
