    STEP 4: INSTALLING THE TIMING BELT. Check for severe cracks or missing teeth and replace if necessary. Place the timing belt around the 2 sprockets (left and right gears) and then install the belt tensioner but do not tighten too much the screw yet. Now turn the white plastic belly in the belt tensioner to adjust the timing belt so it is not too tight or too loose (you should be able to depress it about 1/2"). Now finish tightening the screw holding the belt tensioner just so the white plastic belly does not turn.




    STEP 5: THE NEEDLE POSITION. First just loosen (do not remove) the 2 little screws in the left sprocket body. You need a small hexagonal screwdriver tip but you may try a narrow enough flat screwdriver to loosen them. The goal is to be able to move the rotating hook freely in order to synchronize the rotating hook with the needle position. In other words, we now need the rotating hook NOT to move while we turn the hand wheel and move the needle to its exact position.


    DO NOT lower the needle yet as it could hit the rotating hook. Just position the needle by turning the hand wheel TOWARDS YOU so the needle comes slightly over the needle plate opening.

    Move and center the needle position lever and make sure the needle is also set in the center position. If the lever does not seem to work fine loose the lever mounting screw so you can freely pull or push the needle position lever to set the needle in the center and then re-tighten the lever mounting screw.


    STEP 6: SYNCHRONIZING NEEDLE AND ROTATING HOOK. Turn the rotating hook by hand so the hook or sharp tip point in the rotating hook wall faces the back of the machine. Then, turn the hand wheel SLOWLY TOWARDS YOU so the needle goes completely down. You should be able to see the upper and lower timing marks (grooves) appear on the needle bar when the needle is all the way down.



    When you see the upper timing mark flush (even) with the machine body the needle is at its lowest position. Make sure the rotating hook tip is still facing the back of the machine and in front of the needle or otherwise hand turn the rotating hook as necessary.

    We are now just 3/32 of an inch from synchronizing the needle. Fix your eyes on the timing marks (grooves) and continue turning the hand wheel VERY SLOWLY TOWARDS YOU so the needle and the needle bar raise 3/32 of an inch which is when the upper timing mark disappears and the lower timing mark is flush with the machine body. Make sure the rotary hook tip point is still in front of the needle. Now very carefully (so nothing moves out of position) tighten the bottom sprocket little screws. Re-check the hook tip point and timing mark position. Test the setting by making a few revolutions of the hand wheel to be sure the needle does not hit any part of the rotating hook.




    THE ROTATING HOOK AND NEEDLE ARE NOW SYNCHRONIZED !!!

    We are now ready to lubricate the machine, reassemble the panels and do a real sewing test.

    After downloading the file simply open it by double-clicking it. In this case the manual is a PDF file so it will open with Adobe Reader which will easily allow you to change the page view size from its top menu.

    belem HELP! I'm at a standstill. Can't loosen gear set screw. Also what's the point of removing the left side cover do I pull/remove anything from there? I sent you an e-mail but you may not have received it if I'm not on your approved list.

    Hi Eva, the timing belt tensioner is the wheel or gear between the two bottom gears holding the belt. The inner white plastic is oval shaped so you can "tighten" the belt as you rotate this oval "belly". Just unscrew it a bit so it and hand turn the oval center so you can see how it works.

    I will be today keeping an eye on your posts so you can finish repairing your vintage machine. Be patient. Nothing is easy the first time...

    Give a few minutes to observe my machine and determine if there is an easier way to remove the upper gear...

    Don't worry, be happy...

    OK, no need to remove anything from the top except the damaged gear. With the upper and front covers removed, turn the hand wheel until you see the screw holding the damaged black gear. Insert a flat screwdriver in the "first lever window" so you can reach the screw. Loosen the screw and remind that you will not be able to pull the gear up but instead pull the shaft down a few inches so the gear remains alone on top. Remove it and replace it with the new one.

    Let me know any other difficulties with this or the next steps. Make sure you have a hot cocoa cup or any other delightful treat available in case you start feeling discouraged.

    Enjoy a great day!

    Well, I got the set screw loosened in the old gear, but I'm unable to remove the shaft. It absolutely refuses to pull out. My machine is not lined up like yours. When I insert the screwdriver, I have to slant it down to get to the set screw thus using only one side of the screwdriver blade. I'm seriously wondering if I can put new gear in IF and WHEN I do get it removed.

    Hi MissEva, I also had to slant down the screwdriver a little bit, could you send me some pictures? About the shaft, is it too hard to pull down or are you having other type of trouble?

    It may be stuck after 40 years sitting there so remove the set screw and hit the shaft to slide it down.

    Well I got the shaft to move, got the gear in and I'm in the process of timing. It's really hard. It's almost my bedtime and I get up at 5 am so I'll try it again tomorrow after work. I need to find a hex driver. I have 6 and they are either too large or too small. I had to use the tips of a needlenose plier. Thanks so very much for your help. Couldn't have done it without you.

    belem - Praise the Lord! She sews!!!!! Got it all back together and I only had one small washer extra. Can't for the life of me figure out where it went. BUT SHE SEWS!!!! I can't tell you how much I appreciate your help. Only thing - it makes a lot more noise than my other machines when it runs - in the bobbin area. Not like it's hitting something - just rattles if that's a good word to use. I can move the needle left - center - right and zig zag. It will make some one a nice machine. Now I just have to wait for the Lord to show me who needs it.

    WoW I'm impressed!!! I have one I opened up - a gear fell out - different gear though.
    NEVER let a sewing machine know you are in a hurry.

    The procedure should be similar to remove and install the new one.
    Let us know if we can help. Blessings!

    This just happened to me today. I was so proud of this estate sale find. It was sewing along perfectly and it just stopped. I looked inside and the lower of the two plastic gears is shredding. Glad I found this thread. I'm willing to give it a try. Thanks for the information.

    Would you believe I found ANOTHER one for $7 and it has the same problem? At least now I know how to fix it.

    Looks like you have done some hard thinking on a 457 stylist. My problem is hand wheel hard to turn. Lubricated still no help. Gear in good shape. Everything is turning in the hook assembly but I wonder if some thread is wound up under assembly. Any thoughts. Told a friend I'd could probably fix it for her. Also I was wondering as I don't know the machine but the thumb wheel that you select zig zag or blind stitch turns all the time when I turn hand wheel. Is that normal.

    I had one machine that had thread wrapped around and around and around the handwheel shaft. I discovered it when I took off the hand wheel. I can understand, from the placement of the bobbin winder on the machine how it would happen. I'd say just keep checking for gunk or thread or lint.

    I've learned to look for something simple before you start tearing stuff apart. Your advice things true. I did pull off the hand wheel. I need to look a little closer though as the winder is right in the path.

    Closer look and that wasn't it. Dang I am stumped. Why does it turn so hard? Not sure what to do to isolate the tightness.

    You want to be very careful. If anything gives when those machines are tight, it will be the plastic gear. You will need to be sure to use Triflow oil and put a drop on anything that remotely moves. Give it a few minutes then turn the machine upside down or side ways or the other side - in other words, reposition the machine a couple times - You will need to oil way up in the inside of the machine - anything that remotely moves will need a couple drops of oil. Be patient - I've had one that took a month of setting to get the oil to penetrate into some little stuck up joint. Very gently try to turn it after it has set awhile. I say gently because of the gear. If you want to tackle changing the gear someone wrote some instructions and posted one QB somewhere how to do it. It isn't all that hard looks like. It is the dried up oil in some remote part that you can't see is your problem - not the stuff you can see.

    I've got a can of tri flow and I will try systematically hitting rotating points. The machine sat for a long time so it would only make sense.
