Make sure that when you go into reverse that the needle is down, this is commonly done with ornamental stitching to ensure that the stitches appear the same front to back.

Sounds like excessive belt tension.

Could be a needle bearing that Seiko started using here, not a bushing that Singer used and never gave one problem for the life of the machine. The hole punched in the timing belt is from a set screw that was not recessed in the upper cog.

Nice find!!

1. Most E1 error messages occur because of unstable power being supplied to the motor. • Release the pedal when the E1 error message occurs, then push down again to activate the motor. If the E1 error message no longer appears this was a False error due to unstable power. 2. If the E1 error message continues to appear: • Replace the motor circuit board with a new motor circuit board. Like Wiz said, the Family FESM-550S is very good motor...we no longer offer the Enduro for a reason.

This is an excerpt on how to adjust the gib of the feed eccentric.

$400 dollars is a very low price for a factory puller, especially for the quality. IMCA Global Minerva makes their own machines and parts, they make the 217N Copy.

Philly in da house!

I've seen some popular reviews on this machine. They are interesting to say the least.

I'm not sure, but this appears to be the bracket with hardware used to mount a swing guide. Usually the bracket mounting screws in the casting are 6X1mm set screws. Again, I'm not sure about any of this, but this is where I would start.

Make sure that the tensions are set to give you a balanced stitch. Sew enough for a good sewn sample then cut apart the goods in the middle, say, four layers, in between the 2nd and the 3rd layers. If the interlocking knot is not there, adjust the tension so that it is. This should help provide a stronger stitch, and should do a much better job to hide knots top or bottom.

As a test, sew slowly, then to a stop, and then go into reverse. See if that improves it. Often, on full function machines, the bobbin comes to an abrupt start and stop, and can over spin the bobbin. I would still check the timing. Usually when things are going well in forward but not in reverse, it's a timing issue. CLICK HERE FOR DLN-9010A Books

I missed this one, I'll circle back when I have more time to dig in.

Mitsubishi DU-105, old world Japan quality on par with Juki and Seiko. It's actually a really good machine. 135X17 needle, same large bobbin as Juki LU-563, popular Singer walking feet same as 111W155 or Consew 206RB. See attached owners manual. Mitsubishi DU-100, -120 Instruction Manual.pdf

This machine never had a needle clamp, only a set screw for the needle. Missing are the needle bar thread guide, 10533 see attached image, and the needle bar thread guide set screw. The needle set screw, that is correct in the needle bar, goes through the needle bar thread guide. 10535 is the needle set screw, and again appears correct. If the needle bar does not hole this screw, get a new one and see if the needle bar threads are blown out, and then it's time for a new needle bar complete. It's not uncommon.
