Info needed: Steering knuckle felt

[David Dunlop]

John.

Before foam rubber became so common, felt strips used to be the standard household door weatherstripping, sold at every local, corner, hardware store. Might be worth checking if it is still available somewhere.

John, Find a felt supplier and buy some high grade white felt (the correct thickness) then cut a couple of strips. If you can buy the right thickness, install it so that the factory surfaces are the working surfaces.
There is a steel spring that puts tension on the seal. Buy the correct grease for the hubs. Some greases are prone to the oil separating. You want one that doesn't do that. I cant remember the name of the stuff.
Your king pins are supposed to have a 0.005" (5 thou) preload on them.

If you wait a bit, I'm sure Bruce P. or Bob C. will chime in with the real info.

Has anyone considered PTFE pump gland packing. Its available in lots of profiles and should outlast felt IMHO.

Hi John

I've been faced with finding a replacement on all three of my CMPs I went with leather belting material, as in drive belts for equipment, getting a little harder to find than when I first got it 39 years ago. But still find it at old tractor meets. Saddle, and harness makers could probably help as well.

Had the 1/4 thick leather belt cut to width then soaked it over night in motor oil and installed according to the manual. In lots of years it seems to have done a good job of keeping the ball surface bright and shinny the grease in and the dirt and water out. On the occasions that have had to take apart a wheel hub assembly I have not seen evidence of water or dirt entry on the inside. Always some evidence of grease on the outside but no lube leak problem.

If you can get the felt great get enough to do the job several times over and save the rest sealed in a plastic bag so you will have it the next time you need to pull the hub apart.

Cheers Phil

....and got 2 sets from Dirk at LWD...... with the springs all packed in a nice GM wrapper.

Odd expereince...... a commercial gasket maker in Ottawa had the felt and could cut it to size with a fast rotating saw blade device....... But would not sell to me as I was not a commercial user...... no amount of cash could make him change his mind........ not sure if he moved but the building is now empty.

Grant just fabricated his own felt oil seals for the CMP trialer he is restoring....white felt......worked nice and served as a wipe seal against the axle shaft....seal is unique to the trialer...... Grant may chime in.....

No :TRIALER" IS NOT A TYPO...... that is how the guy at the weight scale spelled it.......

"Trialer" Got the right letters in almost the right order - better than most people seem to manage these days !

Hi Bob

I've run into this problem of only selling to "commercial user" my first response was to put my consulting business card on the counter this generally solved the problem. Only once buying bearings was that not enough. Solution purchase order from Canadian Military Pattern wonderfull what you can do with a computer. Guy look at the purchase order saw the web address, checked the web address and then filling the order.

Only time this approach didn't work was with fabric company from California that would not sell to me because I was a foreign company, guess New Hampshire is now the southern most Canadian Provence.

Ontario may still hold the honour of southernmost province. Point Pelee National Park is listed at 41.962 degrees N latitude. Nashua NH (near the southern border of NH) is listed at 42.765 degrees N. In fact, California also reaches further north than Point Pelee reaches south....
