I'm glad that you solved your question. I didn't see any response to your post, so I thought I'd jump in with the bare minimum of outside support.
I have a coffee grinder on another 130 portable, but not on this one. I'm not sure what condition the other machine is in, because I've had it in storage for a long while. I've not ever had it on the bench yet. It's got the big work lamp too, but I don't know what the cleated belts look like, or whether the linkage moves properly. On the other hand, the main belt on my treadle seems to be in excellent condition, and the bite appears to me to be very generous. Like I said, I'm not much of a Pfaff mechanic, so other than a Pfaff 230 that I've messed with a tad, that's all of the Pfaff machines that I have and have fiddled with....
