Singer Stylist 834 TIMING Belt (2025 Update)

Mar 09, 2013 Last reply: 11 months ago 6 Replies

I have a Singer Stylist 834. This is a good machine but I needed to replace the timing Belt and motor Drive belts. I repair engines so i thought i could take this minor task on.



In short, the Belts are replaced and I tried to maintain all of the original timing with respect to the top and bottom drive shafts connected by the timing belts.



Obviously something slipped. The needle is now being scraped by the bobbin device. The cams that move the zig zag levers for the needle are also out of position so I could not locate any timing marks on the shafts or bushings.



In order to change the inside timing belt the main shaft must be slid out the front of the machine by about 2 inches to get the belt onto the shaft.



Any help would be appreciated- I am trying to align everything by trial and error but not with great success.


The job you thought was minor is actually a very complicated job. The problem you have now is just the beginning, there are a lot more adjustments you will have to make along the way. This is a job even a lot of places that say the repair machines will not handle. If you are local and want to drop it off I can help. It will not be inexpensive, in fact probably more than the $175.00 I would have charged to do it in the first place.

I always charge an extra Fix-the-Error fee to take over someone else's botched job.

I was thinking, when I first read OP's message, "that's a repair which should not be attempted without the *service* manual, and not even then unless one know what one is doing."

Or in fewer words: "Ping Ron!" ;-)

I posted the help singer stylist 834 timing belt question.

It took a little bit of effort and i thank all those that responded for the motivation to get this fixed Without help and without the repair manual. I like a challenge and for those of you that offered to help for $$ I appreciated the offer but i managed to figure it out. It took a great deal of observation but the machine works fine now.

This is a good machine and with new belts it should last well into the future.

Thanks again......

And 8 years later I'm stumped trying to figure out how to get that belt off. I'm stubborn too so I'm sure I'll figure it out but I'll come back and post how I did it

Best left to a professional you have to take the entire upper shaft out

How does the upper shaft slide out? I can't get it to shift. TIA
