Assemble the four short bolts into the housings
with the heads on top. Assemble the long
bolt from
the bottom up through the long
boss. Assemble the
washer, then the nut on the long bolt but don't
tighten until last. Fig.
70.
The correct procedure in tightening the four short
bolts and nuts is to use a criss-cross
pattern. The
required torque on each nut is
35-45
in. Ibs. To ob-
tain equal tightness, tighten one to 20 in. Ibs., then
cross over to the opposite corner and tighten to
20
in. Ibs. Tighten the other one on same side to 20
in. Ibs. and the fourth one the same.
Check the rotation of the shaft in both directions.
If o.k., use the same procedure in tightening
all
bolts to
35-45 in. Ibs. Recheck
shaft rotation.
