Absolutely not a job for an untrained person to tackle. You must remove the entire needle/presser bar assembly, the cam stack, cam follower post, motor, hand wheel and gear, then slide the main shaft to the left far enough to get the belt over. Then put it all back and re-time the entire machine. I am experienced (35 years) and it takes me several hours to do this job. Most repair shops can not even handle it.

I am sure I posted this the other day but it did not show up so here goes again Absolutely not a job for an untrained person to tackle.

It showed up here, twice. Which is just fine, as your advice is always worth at least twice what we pay for it. ;-)

There is an easy way to replace that belt and it is so worth it. I did it myself and it worked great. You cut the belt, loop it around the shaft and slice it back together. While I was at it, I shorten mine from 94 teeth to 93 teeth.

There's an easier way. Cut the belt, thread it around the shaft and then splice the belt back together. I sent an earlier reply with more details and pics but doesn't look like it came through.

So how did you" splice it back together" ???

There's a photo

I presume the pins were cut off after.

How did you cut it exactly and are those straight pins? Looks like a great idea

Hello, we bought our 758 at an estate sale for $65. We have a specific project - patio curtains - and if that's the only thing we use the machine for I will be happy with the purchase. Do you have any specific instructions?

They are straight pins. You need to bend the pins over and clinch them against the belt before you clip them (I tried clipping them off flush but it doesn't hold). I push a couple pins through first BEFORE I cut the belt and then pull them back out. That gives me good alignment holes for after the cut. I just do the cut with a razor blade.

These are updated pics. They sequencially show what I did. There are two pics that show where you adjust the belt tensioner in (at the begining) and back out again at the end. I did this over a year ago and it has worked out great. It is easier than it looks.

A few hours ago, I sent more instruction and photos showing how to do this. They have not appeared here yet. I guess I'll wait a while.

It is not advisable an untrained person should attempt that advanced repair. You must dissemble the upper end of the machine completely and readjust everything on the machine it is a very expensive job find an old black singer for that job

Not advisable

Not true. I did it myself. I did not have to disassemble the upper end of anything. Don't know why someone would say it is not advisable when I've done it and they haven't. Maybe just trying to drum up business but it works great, not hard, see pics.

I'm sure no one's trying to drum up business. You would do the splice on a new belt and discard the old belt. I certainly don't agree that it is not advisable.
