threads of two of the shorter (81 mm/3.1 in.)
head bolts, and install them into location 3 and

switch, insert a long (90 mm/3.5 in.) head bolt
through the special washer (flat on one edge),
and the cutout switch. Install it in position 1.
d. Determine the correct length head bolt for
position 5, based upon the length of spacer

the spacer used is 17 mm (.669 in.) long, use
a shorter (81 mm/3.1 in.) head bolt. Insert the
appropriate head bolt through the spacer and
washer, and install it in position 5. See Figure
11-44.
e. Install head bolts in the remaining positions.
f. Following the sequence in Figure 11-44,
