I had originally posted this question in the wrong place. I don’t know how to move the post, so I’ll just copy the text and replies... I will also post the requested pictures as replies to this post.
Thanks.



I’m fixing my grandmothers old sewing machine. It hasn’t worked for years and I told her I would fix it up for her. It just had a bad switch.
However, the belt is shot.

After looking up the owners manual I see the part number is 60902, which isn’t available, but that number is listed as a replaced part number.

Anyway, they all are for 14.5” or 14.75” belts.

when I cut the old belt and measured it, it was 19.5” long.

So do I just buy a 19.5” belt and not worry about it?

I’m just wondering what I’m missing here.

thanks for any help and advice.

Welcome. We have a section here on Quilting Board that is for Vintage machine enthusiast at https://www.quiltingboard.com/vintag...thusiasts-f22/

I initially thought that was a very long length for a sewing machine belt. I found that indeed the 158.152 does take a long belt - possibly 60904. It was nice that you had one to measure. I found https://www.sewingmachinedepot.com/l...otor-belt-fits and https://www.amazon.com/19-3-Positrac.../dp/B0711N2NVF and https://www.vintagesingerparts.com/p...aces-part-6914

Maybe you would like to join us over at https://www.quiltingboard.com/vintag...thusiasts-f22/ and post some pictures of your grandmother's machine.

We like pictures. In order to post pictures on Quilting Board, you will probably need to reduce or compress the picture to a file size that is smaller than 2MB. How to post images can be found at https://www.quiltingboard.com/attach...020-01-17-.pdf
Don't forget to scroll over to the far right to find and click on the "Upload" button.

I have found that only the big red "Reply" button or "Quote" work to give me the paper clip icon to work for adding pictures.

It looks like you can view the pictures on this thread even though I posted them to a different one. Is that right?

I can click on thumbnails, here in the vintage section, to see the pictures. Yes, it does say 60902 in the manual, which is frustrating when it does not match what was actually on the machine.

Does she have the cams?

I just responded to another person looking for a belt and there is a way to calculate belt length based on the diameters of the pulleys (outer edge) and the distance between the centers of the pulleys. http://www.calculatoredge.com/mech/vbelt%20length.htm

How about running a piece of twine ( or airline tubing for aquariums) round the pulleys and measuring that. If the old belt was fairly snug/tough terribly worn. I would go with it's length.

Hope things go smoothly for you. I'm sure your grandmother will appreciate that she can be back using her machine.
