153Wwsv19

[Frankqv]

I picked up a 153wsv19 yesterday..You might have seen it on ebay recently. The dealer who is shutting down his shop really wants his stuff gone. It's an alternating,compound Needle ,it looks and seems to be the same as a 101 or 104. The needle system is 135x17. The machine had sat for 10 years, it turned over with a little effort,he had obviously dusted it off and hit it with some PB blaster or some other penetrating oil,the stitch length controller couldn't be turned, so the movement of needle/compound was very little.It came with a small table that an Adler patchier had been on. the table is all steel,with a reducer and a clutch motor,nice compact tidy little table.

Got it home and i continued to free it up.Got everything freed up,including the stitch length controller,Mounted it on the table.

The problem is the stitch length controller doesn't change anything when you turn it,the feed is about 1/16 of an inch, and won't change. The other problem with the machine is the Button that is suppose to lock the shaft when you reset the clutch seems to be broke off on the bottom and doesn't contact the Ratchet to lock the shaft when you depress it.

Any suggestions as where to start(re: stitch length) would be appreciated.

This forum has thousands of years of experience,which helps guys like me and others identify problems and deal with them.With a little luck,I can fix the problem,add a servo and be into the machine for less than 350.00

It is one of 2 things.Either the threads are broken on the end of the shaft or it just needs adjusting on the cam(see attached file)

You can pull the stitch adjuster knob out & look @ the threads on the topshaft.Or you can just push the adjuster all the way in & use the screws in the diagram to adj the stitch length.Someone may have these turned out some,or maybe the shorter cscrew is missing aloowing the other one to back out do to viabration of running the machine.

Thanks Bob

I appreciate the quick response,look forward to getting the servo I ordered from you.

Frank, Your Welcome.

You might want to pull the clutch button out & see if there's some dirt under it keeping it from going all the way down.

[Frankqv]

I'll take the button out and see if it's dirty or the end snapped off.

Adjusted the stitch length as per the page you sent me. I adjusted it to give between 5-12 SPI,also timed the hook,sews like a dream.The old clutch motor is on or off,but it does have a speed reducer so it's not out of control,no feathering ,look forward to getting the servo

Thanks for all your help

Attached is a drawing of the feed adjust,the arrow points to a a slotted hole with a shouldered bolt in it,should this be locked down or allowed to move back and forth as shaft is rotated.

Frank

[CowboyBob]

When the bolt is tight the piece under it needs to move freely.

[Frankqv]

Thanks Bob

That's what it does

Received the servo Motor from Bob today,It's a Brushed servo,has a better proportional control out of the box than the Consew Electronic servo I have on a GA-5.The Consew servo had to tune the electronic wiper to get a usable proportional control.Bobs servo Also has the speed potentiometer which makes for quick easy max speed settings.

This makes a great setup. Sewed 138/138 easily,2-4layers of 4 oz,stitch length adjusted just fine,only had 135x17/23 needles.Tried some 138/207, at a slow speed it sewed OK,when I sewed to fast,frayed the thread,sure when I use 135x16/24or25's for 207 thread it will sew just fine.

Sometimes you get lucky,with this machine I did,

Singer 153 with Adler table(included speed reducer),clutch motor. 150.00

Servo Motor from Bob. 135.00

Misc penetrating oil,v belt. 20.00

My time to free it up,clean it up,mount head on Adler table,adjust

Stitch length regulator ,time hook, Mount servo,stay at a Holiday

Inn Express so I knew how to put all this together Priceless

Total. 305.00

My thanks to Bob,for the Servo, and explaining the Stitch Regulator

Still don't know what the sv19 is,seems to be the same spec as a 104

Compound,walking foot,needle feed.Presser 1/2" lift by hand,3/8 sewing capacity

Stitch length 6-28 marking on regulator

[CowboyBob]

Frank, I'm glad to hear you have it going,We used to sell the motor w/o brushes & it is harder to adjust & doesn't seem to have the low end torque like this one.I know SV stands for special version BUT I've never seen anything from Singer explaining it.I've looked & machines before & found what the difference in they also have the 144 with SV on them.You have to put your machine side by side with another 153 & look @ every part.I think sometimes the engineers @ Singer had to look busy so they did things like this.

[SARK9]

I believe some of the other Singer SV models were contract-built machines which had subtle differences such as custom heat treatment/hardness specs on some otherwise identical internal components. The differences may be non-obvious.

Thanks

DC

There are no obvious differences

You can make a clutch motor much more controllable by extending it's lever arm underneath much longer, I extend them by about 8 inches and move the link rod bracket on the foot pedal over to the left so the link rod isn't at a funny angle , this halves the amount of clutch movement for the same amount of pedal depression , try it it'll give you machine the controllability of a servo motor for about 30 mins work and just a few pounds if you don't already have the materials , regards Craig

Thanks MK1,got servos on all my machines
