14. Place o-ring [
S
] within the groove on the
inside of the compressor cover [
R
].
15. Place the compressor cover [
R
] over its
seating position on the compressor unit
body.
16. Fasten compressor cover [
R
] to compressor
body using the four (4) pan head screws [
Q
].
Tighten bolt pairs evenly in a criss-cross
pattern (
Figure 6-11
).
17. Place the compressor tensioner plate [
P
] so
that its holes line up with its compressor
mounting surface.
18. Fit a lock washer [
M
] and sheave washer [
N
]
over an M8 capscrew [
L
], and place it
through one of the upper aligned holes of the
tensioner plate and compressor cover.
Screw it into place snugly, but not fully
tightened.
19. Repeat Step #18 for the three remaining
holes until the aligned tensioner plate [
P
] is
secured (but not tightened) to the
compressor unit; do not tighten the
capscrews yet, as the tensioner plate will
have to be adjusted to allow for repositioning
of the tensioner sheave/serpentine belt.
