Singer 620 Touch & Sew Main Drive Shaft - Gear Replacement

[@overlycreative1]

I read all the comments and responses and get so much more than from watching the video alone, I highly recommend doing so. Great video and work, I love all my Singers.

[@More350Power]

Thank you!

I have a singer 648 and the exact same thing happened to it.. Obviously it's not the same machine but I could assume that the same thing happened, and yes. I was looking for where the problem was because it did not rotate the hook channel and from so many videos that I saw there is no video that showed me about this machine that I have. So, your video specifies more about what could have happened to mine because it is similar and I analyzed well where the problem was so thanks to you and your teaching, I found the issue. The top vertical shaft gear was missing because it did not meet the horizontal gear, which is near the rotation wheel.. Thank again & much blessings!

[@More350Power]

Thank you for watching!

I know this is an older video and hopefully you will answer (crosses fingers) but its helped me except I cannot get the top upper vertical gear out... it has the smallest allen wrench screw I've ever seen..and they are stuck in there... i don't understand how to get it out..its so frustrating. This is for a customer of mine. I own a restoration sewing machine shop and I bought a new gear..now I've followed your video and that top gear just wont budge.what do you suggest? Please help thank you

[@thearough]

I'm going through this right now with a singer 648 i hot a tiny allen that's not tiny enough whyyyy!??!!! Have you gotten any wear in 4;weeks

[@javirosalez5663]

You did a fantastic job of Showing and Explaining, thank you so much for your help.

[@More350Power]

Thank you for watching !!

[@brigidbac1438]

By watching your video, replacing that little part, looks so easy....I took my machine, which I inherited recently) to a repair shop....they wanted over US$150 saying that he needed to replace ALL gears...well, the machine turns on, the needle goes up and down but.....the bobin portion does not move. So I am thinking on replacing this gear like you did.....will it work? I hate to spend US$150 on a gear replacement, OR....toss the machine in the trash.....when there is Singer new for sale for LESS than this repair price...Besides, ALL Singers now, are made in China, of PLASTIC, and they are not a good working tool at all...The old Singers, made of METAL, are what I call....a WORKING HORSE for life. Would appreciate your opinion....

[@More350Power]

+Mariliza B,A,C It was fairly cheap for all the gears with some research. If the existing ones arent showing signs of slipping or being stripped, I would replace what I needed to. The old ones are better, a good lubrication and a fresh set of gears on this one as the wrong ones were installed by a shop previously and this runs like new !

[@jimjewell4109]

I'm trying to replace that same gear in a 648 both the top gear does not have a allen screw in it its like a hollow rivet iv'ed tried to punch it out tryed to drill it out but no luck. do you have maybe another way I not sure what to try next

[@iamyianni]

Jim Jewell some of them did have punches. You’ll need a roll punch to punch

[@More350Power]

I have had some people tell me it has a role pin in it, use a roll punch it should slide right out.

[@CorinneSchneider-rt2mf]

oh and btw its a singer 640 touch and sew.

[@rhondamercado7527]

I just found this machine this weekend and have watched every video that I could find about how to remove the hand wheel. Can you give me some guidance on that.. Thanks

[@More350Power]

I do not have this machine anymore, however, I might still have a donor machine in my basement. I will have to check....

[@davidvalenta9394]

is there a difference between the black plastic gears whose teeth are perpendicular to the center, and the white nylon plastic gears that have spiral cut gear teeth? Both are noted for 600 series.
The white nylon ones are more expensive; is that necessarily better?
Lastly: is anyone making metal gear replacements for the plastic ones?
Are metal better/worse for any reason? (ie: gear breaks vs machine)
Thank you for an 'approachable' and well done video..

[@More350Power]

The black ones are a fiber type gear and the nylon are just that. Other than that, the direction and cut of the teeth are the only difference. The gears I am installing are genuine singer parts. This machine called for the fiber plastic gears while some do in fact call for metal. I would personally not like the metal as if something jams, the plastic gear breaks and not the machine usaly. Thank you for wathing and I apologize for not getting back to you sooner. For some strange reason my youtube did not let me reply to comments till today

[@davidvalenta9394]

THanks much!
I'd found a set of metal gears for my 626, as well as plastic..so I'll proceed w/ caution.
__
Since my earlier post: kind of a bummer: I've got -two- Singer 626's; and within minutes of using the 2nd one, the needle came down on ''metal".. and I'd only sewn about 1 yard long, simple seam.. Any suggestions on how I may be throwing the timing (?) if I'm -not- pulling the fabric through?(basic straight seam, not-thick materials)..
* I -do- appreciate you putting this information and description of processes up; it's very helpful, and encourages me to try to fix stuff vs just shelling out about $300 to fix 2 machines. -Thanks!

[@iamyianni]

David Valenta did you fix it? Did the metal gears work? There’s a video on here dealing with setting time of touch and sew. If you need I can find it

[@khanscombe619]

I have a 640. 2 years failed, 1 top & 1 bottom. Can i use main drive as metal & others as old black fiber style?

[@1953childstar]

@@khanscombe619 You cannot mix metal and plastic gears. All the gears need to be replaced at once for a beneficial outcome.

[@emono2396]

Hi- i found that the top vertical gear is broken for my singer 626. is it possible to just remove the vertical shaft without disassembling the horizontal shaft as well?

[@joy849]

I have the same issue on my 636. Is it possible to just remove the vertical shaft without disassembling the horizontal shaft?

[@More350Power]

Im not sure about different models, but as i did in this one, It had to be done step by step. Otherwise you would get things jammed up.

[@traciderby1046]

Hi
Nice video. I just had all the gears replaced in this same machine and it worked for a while, but now turning the hand wheel only turns the mechanism inside gear one, but doesn't turn the gear. I can freely turn the gear by hand to make all the others turn. Any ideas? Thanks!

[@More350Power]

Traci, from what your describing when you turn the main wheel/crank whatever you want to call it..... the needle moves but the bobbin mechanism does not, and most likely the feeder under the pressure foot doesnt work either. Am I right ? I had to tighten and re tighten after I timed it after running it a bit in between. It sounds like one of two things happened to yours. One, one of the gears loosened up and is not meshing with one of the others or, like the previous repair shop did to this one when they replaced the gears, they had ones that worked, but werent the correct part numbers and after a little a few stripped out. Most likely one of the set screws on one of the gears is loose letting it spin on the shaft that it is supposed to be tightened to....

[@aprildaneenersnana845]

@@More350PowerI was so excited to finally find these videos as the 620 is the exact machine I have and it has the same broken gears that need replacing. I see this video was posted years ago but curious if you have a list of the correct size gears so I can avoid putting in the wrong size/type that you noted the previous repair shop did. You make it look so easy!! Hope to give this a try once I find correct gears. Thank you!

[@tinapickett4692]

Is it possible to change the lower horizontal gear without removing the shaft? I would like to access the broken gear through the bottom of the machine and put the new one on. I am afraid if I take the whole shaft out, I will create a bigger problem for myself and won't be able to fix it at all.

[@More350Power]

you probably could, but it may be more difficult to get it in or out. I tore this machine apart several times before making this video to find the easiest way to replace the parts. If you replace one, you might want to replace the others especially if they are the fiber gears like these.

[@tinapickett4692]

Thank you. I am going to try it. My hands are tiny, and I think I can reach inside as long as a have a screwdriver small enough.

[@secratpandoraok4145]

Same problem

[@alfonsootero5446]

[@mlaux72]

should be the same with a Singer 6212c?

[@More350Power]

They are close, but there are some differences in size, set screws...... I think the gears that were in this machine that got destroyed were for that model. They were just a hair off

[@vijayalaxmi9241]

Usha janome. Empress gear part...is there any availability? Pls respond

[@More350Power]

The gears for the machine I have here or a different model ?

[@theresecrouch2924]

how do i replace bobbin holder and little thing i pulled out to get it out

[@More350Power]

are you referring to the actual spool that holds the thread that you want to change, or what it slips down into ? Also are you referring to the black spring clip that kinda slides down into place ?

[@glockstitch]

All 5 of my gears are broken.,. Can i replace with steel gears??

[@More350Power]

I wish they made steel gears for it.......

[@totocat4421]

If you allow, are there sizes for this gear? thx

[@More350Power]

I dont have the sizes unfortunately. I had assumed the ones installed in it prior were correct, but found they were a millimeter or more smaller which caused them to skip and strip out.

[@gayastudio5471]

hi
can you please help me with my singer 354 gear replacement
becous the upper gear has no screw to remove
how i can remove it?
thanx again

[@More350Power]

There should be a set screw somewhere or a rivet.... if there isnt, it is probably part of the shaft assembly.

[@1953childstar]

It has a "shearing pin" that needs to be punched out...

[@rhondamercado7527]

Oh no! You just scared me….I hope I’m successful in changing out that top gear🤦🏻‍♀️

[@More350Power]

With some patience and steady hands, this can be done with ease.

[@sdvr1]

hey nice video!
please I need to know where did you ordered and parts information please..I really need to buy the same parts

Well this isn't very helpful if you don't show how to get the shaft off to begin with!

I did a small series and split up the videos. If you havent found it already you want to watch th-cam.com/video/eDKcJZqAMmI/w-d-xo.html and skip to 6:50 if you want to see the removal. This was a multiple series and I did things in steps. Part two there was disassembling the gears. Thank you for watching and I hope this helps, thanks!
