Why will the bobbin race assembly on my singer touch and sew 640 will not move?

This specific model, and most of the Singer Touch and Sew series of machines has several plastic gears that drive either or both the hook, and the feed dogs. Due to age and general wear, these gears eventually break. It is almost 100% likely that one of your gears is broken. It is recommended that you replace all of the plastic gears in your machine at the same time. If you just replace the one broken gear, you are merely shifting the weakest point in the system to another gear, which will also break shortly. If you replace all the gears at once, they will be of equal age and strength. It is best to get this done at a reputable sewing machine repair shop, as this repair involves a complete re-timing of the machine, and can be quite difficult for the novice.

My hook gear has gone bad, I have singer sewing machine model # 834, I need help with how to take the parts off and replace them

Follow this link, click on the hook gear parts, and you will see a link to a video showing how to install these gears. I was able to follow this video and replace the gears on my old machine. For me it was do-able, but moderately difficult. If you think you're up to it, go for it. Replacing all for gears a t once will cost $50. (Singer 834).

Rotating Hook won't fully turn-Singer 2210

The nylon gear driving the hook has probably broken a tooth. Replacements are available if you search the web.
Make sure you get the matched set of driving gear and driven gear.

Singer stylist sewing machine 534 is not stitching

Its quite possible that the stitch length knob is set on 0 or that you have the feeddogs set on darning which drops them below the plate (if it has this feature). Otherwise the feedogs are gummed up and everything needs a good cleaning and oiling.
Hope this helps.
