I had bought this White Rotary 77, came in cabinet with accessories and manual at an auction back in the fall for a whopping $2.50. Around here people are afraid of old vintage sewing machines unless it's a Featheweight or older Singer. It seemed to be in great shape and taken care of over the years.

After get it home and pugging it in it worked except do to sitting the flat spot on the rubber was making it clunking nosie and sewing in different speeds when it would hit the flat spot. I believe I read here that to make sure the motor drive wasn't toching the wheel when not in use. Planned on ordering a new drive pulley but noticed there are several sizes, not sure which size I needed. So I had some left over batting and decided to in the mean while keep the pulley and wheel apart hoping not to cause any more indents. Well even though the rubber is hard and sure it due to it's age I noticed the dent was not as indented a few days later. Since then I still put the batting on when not using it but now the indents are gone, so while using it it has smooth out the indents. Yet I still need to get a new drive pulley with better newer rubber...just to figure which size. I don't have a tool around to figure out the measurment.

I have a White rotary with the same issue. You might check with Sew Classic for replacement parts.

"What I do when not using my White Rotary 77 to prevent flat spots"

You don't have to move it much to get the pulley off of the hand wheel. I put a thin stick such as a tongue depressor or even a pencil between the motor housing and the back of the casting.

Since I been using the batting to keep the motor pulley away from the wheel, the rubber is smooth now so when I'm not using it it no longer clucks and sews smoothly now, no speed differences at all.

Thanks for the Sew Classic information I have been to their site many of times, there are several sizes for White 77 motor pullieys I'm just not sure which size to order for this one? The local Sewing mechinc said for me to bring it in as he might have the part for it in the back room, I told him it way to heavy for me to carry in and it's in the cadinet...so he tells me to take it out of the cabinet and I say this machine weighs a ton, well maybe not a ton but I'm beting about 45 to 50 ibs. So I asked what if I take off the drive pulley bring it in and see if we can match it up? He says that might work...lol

I think you are right Cathy I am going a bit far! lol

All of my White made machines with that type of motor have 1/4" shafts. Sew-Classic doesn't have pulleys with that size hole in them and if you use the slightly larger one you'll get an off center drive wheel that will give you the same effect as the dented rubber does.
Thayer Rags Parts { http://thayerrags.com/ } had some 1/4" pulleys at one time and so does Sewing Machine Parts Store: { http://sewing-machine-parts-store.co...&brand=&page=2 }.

I have replaced the rubbers on several of my drive wheels and they work, but it is difficult to do on some of them.

I use acetel rod I steal from my wife's craft supplies to hold the drive wheel away from the hand wheel.

I also use scrap batting tucked between the motor and machine pillar to move the motor away from the drive wheel. As I remember there is a little set screw that holds the drive wheel onto the motor shaft. If you take the drive wheel off, guard that little screw with your life. Put it in a little baggie so it does not disappear. Don't ask me how I know!

Joe you should do a tutorial on how to "replaced the rubbers on my drive wheels and they work, but it is difficult to do on some of them" with pictures!!! I know many of us will just love one!

Have had the same type of think happen to me and never to be found again. Then yet we still look for them for weeks hoping it will be found...lol
