111wW115 hook replacement

[leecopp]

I brought home this craigs list find ($150) and it looks to be in pretty good condition. Drive chain seems good, not a lot of buggered screw heads, most of the paint intact, decent table with modern style clutch motor.

Since i busted the drive belt trying to get her freed up I thought i might replace the hook while I was in messing about.  Has anyone run up against a good document for hook replacement .. or even better a video?

I have been through most of the sites archives .. but I didnt have much luck on this topic .. (may have missed it in a senior moment).

ps. the underdeck movement still seems pretty tight .. I have re-oiled and plan to put it out for a sunbath again today (sunny florida). Any particular locations that seem to get bound up (no thread nests, very little dust as found).

The hook can get jammed up& tie up the lower shaft,so put some oil around the bobbincase & rock the lower shaft back & forth.

The US army technical manual https://archive.org/details/TM10-3530-202-24 describes how to remove the hook on a Singer 111W155 starting on page 114. It also covers hook timing with accurate specs.

Removing and reinstalling the hook for cleaning and inspection (Or installing a new $35 Hirose Hook)  may be a good idea anyways. I almost always find thread fragments lodged in place you can't even see.

Hey Guys, thanks for the assist.

Thank Uwe for the Army manual reference, it helped clear things up.

Thanks Bob, makes good sense.

I got the new timing belt installed with no problems (arrows match with takeup lever up) and the hook timing looks about right (whew). Ran the machine under motor power and seems to spin just fine.

But you know the part of the "Keystone" Navy manual that says 

"Timing the presser-lifting eccentric

The presser-lifting eccentric controls the feeding motion provided by the alternating pressers.

If the presser-lifting eccentric is not, properly timed, it can cause the machine to feed backward or prevent the machine from making the full stitch length."

Bucket list check off, yep my machine is feeding backward

Seems like someone might have been messing with stuff before I got this machine.  This may not go down easy!

Make a video of your moon-walking machine and add some Michael Jackson music to go with it. 

That Keystone version of the Navy manual does have the wrong spec for hook timing needle rise, by the way. The Army manual is correct.

Army against Navy - wondering what the Marines manual says

leecopp, how did you solve the problem with the machine sewing backwards? I have the same problem.

Hey Game,

The whole issue is in the adjustment of the presser feet .  I have done 2 of these machines and both were tough for me to dial in ( I am an admitted rank amateur). if the adjustment is off the vibrating foot does not clear the feed dog and that pushes the material forward.  Be patient, it took me many adjustment cycles before everything fell into place.

There is a good discussion of this topic at  :
