Hello,
I've had a Red Columbia Gold Award machine for 30 years, but it stopped working around 15 years ago and I just let it sit. This week I decided to finally take it a part and id the issue. The previous owner appears to have used grease that has gotten tacky over the years. It's typically not an issue to clean tacky grease as long as the pieces can be separated.
My problem is that the A71 payout gear is mounted on a bearing shaft that is really gummed up and hard to turn. I thought I'd ask the experts about this assembly before I continue.
I've attached a photo.
I've loosened the bearing shaft by removing the hold down screw in the frame but the shaft does not come out. It will spin a 1/4 turn and stop. I assume there's a bur holding it in the frame or perhaps it should drop out the bottom of the frame mount? I'm not sure if the silver washer on top is threaded or pressed onto the center bearing? Should the washer pop off? Should I be able to slide A71 up and off the bearing shaft? It's hard to tell without an exploded view of the shaft and bearing.
Thank you for any assistance,
