Airhead wheel bearing greasing tool

Hi Airheads

I would like to grease my R100RS`s wheelbearings.

Saw a couple of references to a greasing tool to insert in the wheels, giving a couple of good squirts.
Even saw a pic. It is a tube with a grease nipple at one end, closed the other end and o-rings acting as seals.

I would like to make one of my own.

Does anyone have a set of dimensions I can work from please?

Airhead regards

Mike

I got mine from Cycle Works also....works great. The process involved in removing /5 wheel bearings at each service interval is dicy at best. This tool is not meant as an alternative to a removal / inspection.... but if you know your bearings are good, it is a great, quick way to grease the bearings. For $24.00 it is a great buy.....figure the time machining / fabricating your own and $24.00 is pretty cheap.

Well, I actually was going to ask the same question sometime soon, too.

I like making things. I've got lathes. I've got bar stock.

If anyone has some dimensions/pics, I'd appreciate it.

Will they work on /7 or later bikes? Wheel bearing maintenance is one of my weak points.

According to the Cycle Works website, the tool works for bikes up to 1984. After 1984 the bikes had sealed bearings (i.e., no periodic greasing).

For what it is worth, the late Fred Taush once told me that the wheel bearings in his 71 R60/5 were original at 600,000 + miles. He used the bearing greasing tool each time he replaced tires.

I've got one of these and love it. And it's really pretty simple so I don't see it taking much to make one up. I'll try to remember to dig it out tonight when I get home if no one's posted dimensions first.

It's only needed on the right side bearing (the captive one) in the rear wheel.

And I belive it that bearings could last 600K - they're way over-engineered for the job and if greased and preloaded correctly should last forever.

... and http://w6rec.com/duane/bmw/wheel_bearing/index.htm has more than you ever wanted to know about the tapered roller bearing setup.
