Singer HD 4432: Lower bobbin group pieces , maybe a screw is missing.

Sat, 01 Aug 2026 00:01:05 -0700

After having paid a fortune and being screwed up by the singer repair centre, as the machine returned home with the same problem, I decided to fix it myself.I believe the problem is very simple..IN THE LOWER GROUP containing the little bobbin reel of tread , the bobbin is lodged into a round black plastic housing of which ,at its bottom has a metal little round shaped with two holes, one little and one larger.. I discover this plastic round housing the bobbin of tread has no screw to keep itself fixed to the machine ( the bigger hole matches the position of an existing hole inside the machine.). I BELIEVE this can be the cause of the machine getting stuck after a few stitches and a loads of tread pieces are pulled out from the lower mechanism every time the machine gets stuck in the sewing process.

I need to know if a screw is needed or not to keep the housing of the bobbin of tread fixed to te machine.

I found this spring laying loose in the bottom right of the machine when I took the plastic off to oil it. I cannot find it on any part diagrams. All functions seemed to be working before I oiled. Does anyone know where it goes?
