Default Multipule disc clutch pilot bearing

Was the multiple disc clutch pilot bearing the same as that used with the single disc clutch?

Thank you.

According to Bratton's catalog, the multi-disk clutch did not use a pilot bearing.

Methinks that you're confusing the pilot bearing w/the release (throwout) bearing

Well I goofed up also. The bearing # I gave is for the Main shaft which is the shaft inside the cluster gear.
Parts list shows: A-7600-A is the clutch pilot bearing 1928-31. IIRC that's a 6203 bearing.

Big green book ALSO shows a pilot bearing page 346 P/N 70-7600-B called "OILITE"

I believe that this might have been an Oilite bushing ...

along with a felt washer P/N A-7608

and a retainer A-7609-A.

Footnote says that felt is "no longer supplied"

On side note:
Bearing 6203 was also used on various IBM machines over the years.

I have a couple of those bearings in the bottom of my toolbox, been there for years, came out of flathead V8s. I'll try and remember to get a picture later today.

Here's a picture of the "oilite" bearings along w/a used 6203. They don't say Ford on them so maybe they're aftermarket replacements? I always kinda assumed that they were bronze. The 6203 looks smaller in the picture, but they're all the same size.
