Assembly
NOTE: When assembling the spool and sleeve, only
one of the two possible matching positions of the
spring slots can be used. The reason is that in the other
end of the sleeve and spool (opposite end of the spring
slots) there are three slots in the spool and three holes
in the sleeve. These must be opposite each other on
assembly so that the holes are partly visible through
the slots in the spool, refer to Figure 5-8.
1. To install the neutral position springs, place a
screwdriver in the spool slot as shown in Figure
5-9.
2. Place one flat neutral position spring on each side
of the screwdriver blade. Do not remove screw-
driver.
3. Push two curved neutral position springs in be-
tween one side of the screwdriver blade and a flat
spring. Repeat for the opposite side. Remove the
screwdriver.
4. Slide the inner spool in the sleeve. Compress the
ends of the neutral position springs and push the
neutral position springs in place in the sleeve.
5. Install the cross pin (9, Figure 5-7).
