8690 Series Disassembly and Assembly
6. Match up the second side plate (P8621FS) with the
first and place it over the detent spacer and pivot bolt.
Do not insert the spring ends into the plates at this
point.
See Illustration 4.
7. Hold the left handle (P8606FH or P8606TN) in a vise
with the drive pawl facing up and the handle pointing to
your left. Pull the drive pawl up, moving counter
clockwise, and insert a 1/8” rod or nail through the small
holes in the plates near the drive pawl to hold it in a
horizontal position.
See Illustration 5.
8. Place a small amount of grease on each of the two
crank plate bushings (P8646FS) at the shoulder and
insert them into the pivot bolt hole with the shoulders on
the inside. The grease will hold them in position.
9. Hold the side plate assembly firmly with the notched
edges of the plate facing down. While holding tightly
between your fingers, remove the pivot bolt.
10. Carefully insert the plate assembly into the left
handle between the bushings (P8646FS). Align the
pivot bolt holes and slide the pivot bolt into position from
the far side of the handle.
See Illustration 6.
11. Assemble spacer (P8644FS) and nut (P2666K) to
the pivot bolt and tighten up snug.
Note: This assembly
must pivot freely.
12. With a small hook tool, reach up from the bottom of
the assembly, between the plates, and hook the ends
of the detent spring into their respective holes.
See
Illustration 7.
Make sure the spring loops are not
caught between the pin and side plate.
13. Remove the 1/8” pin from under the pawl and
engage the drive pawl with the sprocket (P8624FS).
14. Remove the handle from the vise.
15. Hook the longer loop on the chain spring (P8678FS)
onto the free end of the chain (P8653FS). Lay the left
and right handles on the bench with the drive pawl on
the left handle and the chain on the right handle facing
each other. Feed the spring on the chain over the
sprocket and into the left handle.
See Illustration 8.
