Jersey Fire Fighter,

I'm working on this issue for sure 100 percent, and was unaware of this bobbin winder O ring variation.  The problem is that the Ferdco Pro 2000 uses the Juki parts list with no corrections or updates.  The rubber O Ring from Juki will not work as a direct replacement.

I have a quantity on order and when I have them you'll have one sent out to you, but this time the correct one.

Juki has two variations, and now we are looking at a third from Ferdco.  

Indeed that is the part to the left. I was getting intermittent misses of the bobbin spin and then one morning the bobbin winder was DOA. after pulling it and cleaning it the issues haven't been as prevalent, but I suspect that it will give way soon enough. I see that after 2 years of wear I had a sizable amount of rubber collected at the bottom of the housing, so it should only be a matter of time. I've called it a Juki clone for a while, and always considered it nearly interchangeable with Cowboy or Cobra, given the two variations of parts manuals I would be wiser to just consider the machine it's own and refer to the diagrams included with the machine.

Well, it's the same assumption and mistake I made here, going by the book, if you will.  Hope to have this to you.

I agree with the boys above, Cowboy Leather Machines in Australia keep the rubber tyres in stock, as eventually they will fail.    Yes there were/are two types, the big fat one seems to be the latest one.   If you get charged more than a few bucks for the tyre someone is pulling your leg.
