Replacing Other Thread Tensioner Parts
The individual thread tensioners may be disassembled by turning the knurled
adjustment knob counter-clockwise until it comes free. Underneath the
adjustment knob is a ribbed plastic disk and a tension spring. The knob, disk,
and spring all nest within a large outer housing that, in turn, rests against
a felt washer and the two-piece, notched thread wheel. The threaded shaft that
retains the entire assembly is mounted to the tensioner bracket as described
in the procedure located on the previous page.
Figure 1-16
Refer to Figure 1-16 for part location and assembly order when replacing
any of these parts. For proper tensioning adjustment refer to the Operation
Manual.
