    My motor says BA 3-8 and underneath that it says S.S. AU52-17-1

    Motor was manufactured in Elizabethport, NJ

    The machine was made in the UK, and is a 201 with the light on the back of the machine instead of the front. Someone put a 110 volt motor on it so it could be used in the USA.

    Then it gets weirder and weirder.

    The chart says BA 3-8 Part # 102393-005 is for the model 15 (except 15-91), 66, 99, 128, 223, 237, 239, 293
    I show PH8 for the 201-2 and 1200 series

    The BA3-8 falls under the BA3 series. The parts diagram doesn't show grease wicks or springs, but in the "Procedure for inspecting motor" Step #7 of the "At the repair bench" section suggests checking the Lubricating wicks and springs.

    Only only risk I can see with removing the wicks on a motor that's supposed to have them is too much of the grease "heating up" and running into the bearing and its surrounding area. If memory serves, often it doesn't so use your own judgement, this shouldn't be a problem.

    I guess the side effect of that would be running out of grease in the cups sooner.

    Thank you for looking it up! Thank you for the info. The felt was all the way to the top of the ports, only a miniscule amount of grease would fit on top of the felt. And not a bit of grease was in it, so I'm thinking this machine didn't get much use. My machine certainly is weird! I don't think grease ports (tiny little tubes) are supposed to have felt in them. It seemed as if the felt was in pieces, not all one piece or it would have come out easier.

    There is a clue in the section called "at the repair bench". It says check the wicks "and springs", which tells me the motor they are talking about is one with grease cups where you can remove the springs and wick.

    Only the 201-2 has the potted motor. There were several different versions of the 201 just like the other Singers. I would almost bet that was a machine made for the foreign market and someone retro fitted it with a domestic Singer motor when it was brought here.

    The motor is greased so that's what's important.

    From what I've been able to determine, my machine is a 201-3. I wanted a 201 with the light in the back so I could avoid the 201 tattoo. I have a slight brain injury so reaching under the light, if in the front, would be a problem for me... I can focus on just a few things at one time.

    I'm happy with the machine! It's humming so quietly as it sews. I can't find a manual for a 201-3 online anywhere though. Don't really need one really...

    Christine, the felts *do* belong in the grease tubes. If you remove them and allow grease to flow into the motor unimpeded, it is only a matter of time before your motor becomes flooded with grease and dies. The grease is only supposed to lubricate the part of the shaft spinning within the bearing. The wicks moderate the amount of grease that can make it down there.

    I'd recommend you place them back in the motor, or you'll probably be looking for a new motor in a few months.

    Those felts, when they're old and non-lubricated (like yours, and the ones I had in my 15-90) do get really hard to take out intact. I have found in a couple of motors so far that the springs were "optional". I think the stuff at the top of the parts page, referring to checking wicks and springs may have been generic, but it's at the top of every parts page. They could have changed it, but didn't. *shrugs* I dunno why. The 15-90 had the wick crammed all the way up the tube too, it came out in a few pieces. I ended up using a blunt pin to push it out from the top, but your corkscrew method bears some thought for the next time I get one I have to do that with.

    Thanks for that clarification Joe! I had actually never seen (or at least recognized) a 201 in person until Tuesday night, I'd just read that they had a potted motor like the 15.

    I have a FW tattoo for the same reason. That machine taught me not to use the light anymore, and i sew with another light on above the machines now. Sometimes it's one of those light / magnifier lamps that you can move the arm about, or else a stationary fluorescent meant for being under a cabinet.

    I ran across a 201-3 on Tuesday. It belongs to a lady who's not going to part with it, but she wants it tuned up once she finishes a project. When her husband brings it to me, I'm going to ask him to bring me the manual we found in the drawer too, so I can scan it. I'll make sure I get a copy to you once I do that.
