Take the end cap off & remove the 2) screws one @ 3:00 & one @ 9:00 & it should just slide out.

My guess is there's a spring missing in the stitch length,open the top oval plate,then push the needlebar front to back & see if you see movement there.There's a screw(#200607) w/a larger head on it maybe 1/4" & it is supposed to have a spring(#202295) under it. Singer 153W101-1 stitch length.pdf

If you need a spring we have them in stock.

@BirdpathThis screw is the standard attachment screw #286S 9/64"x40 tpi if you can't find ant we stock them.

This motor has sealed bearings,there (might) be an oil hole in the center of the casting to the left of the pulley to lube the bearing for the clutch.

I have some 214x1#19 in stock,since this needle is longer & the machine was designed for heavier leather you won't find a leather point smaller then #22.You might not want to hear this but a smaller machine like a Singer 111w,Consew 225,226R,Juki 562,563 would wotk alot better & mark less than the 132 & you can get leather needles down to size#14.

Sounds to me like you've missed a spot when you oil?Re-oil everything you can esp on the arm.

@john27 Are you sure it's hitting the foot or is it the feed dog?

@cadet4x4Yrs ago we used to put the reverse & highlift on these.We have the needles,bobbins & thread in stock.You'll need to let us know the current needle length.The bobbins should measure 3/4"x3/4".

@TomEGrease will never work into the inside shaft of the roller so only use oil,see attached file for a manual that should work for this motor.Servo motor directions.pdf

Most people we sell thread to use nylon for patches.

Go to page #26,loosen the screws #42 & turn cam #41 (walking foot cam)to adjust.You access it from the backside of the machine.

See the thin piece of metal on the bottom leftside of the pic(underneath the point of the hook? Bend it towards the needle,this is call hook guard & is bendable(adjustable) the stop the needle from hitting the point of the hook,once in a while if it's hitting too hard you might need to loosen the 2 screws underneath the hold the whole assembly in place & move to the right & then you'll have to move the big over to match it.Try bending the guard first since it's easier.

Take the old one off,get a foot pedal & fasten to lower parts of legs and you'll need a longer chain to connect from the head to the pedal.

In the parts manual go to page#3,item#50 is the cam you need to turn to change when the inside foot comes down,loosen both screws #50 Consew255RB-3 parts & opermanual.pdf
