Probably not a lot of people trying to adjust a belt on a Singer 347, but that is where I found myself here recently.
I wanted to make this classic Singer purr but It just wasn't keeping up after I spent several hours cleaning and servicing. The belt was slipping. There didn't appear to be a belt tension adjustment where I thought it should be. Finally, hidden in the bottom of the machine and part of the motor mount was the adjustment!
I think they call this an eccentric screw adjustment. You loosen the screw, turn the washer with the off set hole, and it tightens the belt by moving the motor further away from the hand wheel.
In this case, the belt was streached too far and beyond the adjustment of this machine. I had to put a new belt on anyways. I ended up using a streach belt. They work fine but don't last as long as the original V-belts.
What a great, simple, early zigzag, sewing machine.
Love that color? Classic 50's! and it sews great.
Thanks for this. I have just been given a 347 as a 2nd machine and it needs some TLC including the belt. Do you know what year they were made?
ReplyDeleteI've adjusted the belt from your instructions thankyou. I need to replace the belt at some point soon, as it too is now at the end of its adjustment.
ReplyDeleteDo you know where you got this machine? I've been trying to track one like this one that was mistakenly sold at a garage sale in greenfield, IN last year.
ReplyDeleteare you still looking? have one I'm in California...

DeleteHello. I am trying to find replacement brushes for my Singer 347 motor. Any idea where to find them? Thanks!
ReplyDeleteI have been unable to find a part number for replacement carbon brushes for this machine. There are several generic brushes for sewing machine motors available. I no longer have access to a Model 347 so I can't check to see what they use. Brewersewing.com has 3 sizes. You can also download a parts list for a 347k too. The list doesn't include motor info. By the way, a pair of brushes shouldn't run more than $3.00.
DeleteThank you so much for this post! I am replacing my 347's belt and couldn't find how to raise the motor for the new tighter belt. Huge help!
ReplyDeleteThanks for posting. I bought one of these on eBay and love it. I replaced the drive and timing belt. Runs great!
