Position Bracket and Position Finger Adjustment:
Click here to return to index.
1. The Position Bracket is a common area for troubles. Many times I’ve seen the spring broken off, and this allows the
Bobbin Case to come off the Hook Railing. It’ll cause thread jamming, tangling and all other kinds of problems. If not
taken care of promptly, and you continue to use the machine in this condition, you run the risk of damaging the Hook,
Hook Driver and Bobbin Case. And that gets costly.
2. A good Position Bracket, along with a broken one is shown in picture A. Check the spring to ensure it is intact, and has
the proper clearance between the spring and the bracket itself. You can get away with attempting to reshape the spring,
but be extremely careful. Being too aggressive with it, and you’ll break it right off. I know, I’ve done it plenty of times.
Also notice that one is silver, and one is black. Normally the black one is either a good aftermarket, or genuine Singer
replacement bracket. The original Singer bracket had an entirely different shape. If you bracket doesn’t appear to be this
shape, good chances are that your machine is still equipped with the original bracket. If it’s in good shape, don’t worry
about it too much, but if it’s damaged, I’d replace with the newer style. The silver one I just received, and it needed
work to even fit into the machine properly. Must be good old aftermarket stuff again. The screw mounting hole was to
small for the original screw, and the adjuster hole didn’t fit around the eccentric adjusting stud. Reference picture B.
3. The Position Finger is also an important part of the Bobbin Case retaining system. It hardly ever needs any adjustment,
unless of course someone has fooled with it, or it was necessary to remove it in order to remove the Hook.
ote the broken spring on the right bracket.
This is what happens when you’re too
aggressive in attempting to reshape it.
The spring should no more than 1/16” and no
less than 1/32” gap between the inside of the
spring, and the bracket itself.

otice the shoulder on the fastening screw; it has to fit inside the mounting hole properly (1). Also the
adjusting eccentric stud (2) must fit properly inside the adjust hole of the bracket (3). Item (4) is the
Position Bracket locking latch, and its primary function is to hold the bracket down and keep if from
umping up. Also be aware that not all eccentric studs are like the one shown. The early models do not
have the extra lip area as shown above (5), and not all machines had the Locking Latch either (4). So if
yours doesn’t, don’t worry about it. However you should be able to obtain the Locking Latch from a
reputable dealer, and I would recommend installing one. Originally when it was first introduced, it came as
an entire kit.
