Jump Stitch Solenoid Replacement
If a jump stitch solenoid must be replaced, follow these steps:
Head #4
1. Remove the left color change cover behind the tensioner bracket assembly by
first loosening the top two screws then removing the side two screws.
2. Cut any and all cable tie wraps holding the jump stitch harness, then disconnect
the jump stitch harness connector from the color change PCB.
3. Remove the 2 screws holding the
mechanical jump stitch mechanism
and cover to the jump stitch bracket
(see Figure 3-33). Remove the
mechanism and cover.
4. Remove the 2 jump stitch solenoid
bracket screws (see Figure 3-34),
then remove the solenoid and the
solenoid bracket as one piece.
NOTICE: Before you remove the solenoid
from the bracket, record the
number of threads of the
solenoid that are showing
beyond the solenoid bracket
(or measure the distance that
the end of the solenoid
protrudes from the solenoid
bracket). When the new
solenoid is installed into the bracket, position the solenoid with the same
number of threads (or distance) that you recorded in this step.
