The crank pulley on my roadster is pretty bad, so I was going through my stash of 1909-1920 pulleys looking for a better one when I came across this.





I don't recall ever seeing one liked this. The leather is attached with four brass rivets. The only ID is the numeral 8 stamped in the leather. I'm wondering whether to use it or a regular pulley. Anybody have some information about this thing?

Looks like an home made "improvement" for a slipping belt problem

The surface of the pulley should be crowned to keep the belt centered w/o flanges on the sides. I suspect less crown and/or easier worn off crown with this soft surface on the pulley, so I think you'd likely get better service without the leather there.

Super, that is the rare Leather Wrap Pulley, made for only oone week!

Henry found out about the change and ordered the engineer to stop production, as he didn't want either Cow Magnets or Cowhide on his T.




My T got the later cotton band lining wrap, that was ok with Henry.

Might it be for changing an early pulley into the larger later style pulley to use up old stocks of the early ones by some enterprising accessory vendor?

I like the bolts and square nuts. Very creative.

Or is it for the cars with leaking waterpumps? Tighten the waterpump to stop the leaking, add friction material to keep the waterpump turning from the tighter packing nut.

You have it! That dang pump needed a padded pulley to pull the tight shaft to push the coolant.



Just got Nellie and the first task in order was to remove that pump

They are after market, I had a new old stock I got with som NOS T parts, I pitched it.

If you put on New pulleys, or renew the crowns on the old ones, and align them, you will not have any drive problems.
