MAINTENANCE MANUAL
(g) Insert the dipstick to its stop position (Refer to Figure 13). The stop is the angle near the
top of the dipstick.
1 The point of the angle must be to the left if the mounting angle is to the right.
2 The bottom surface of the angle must be flush with the surface of the oil filler hole.
(h) Remove the dipstick and count the increments of oil.
(i) Use Chart 7 to determine the correct oil level for the mounting angle of the compressor.
(j) If the increments read on the dipstick do not match the table, add or subtract oil to obtain
the mid-range value.
(k) Install the oil filler plug, first checking that the sealing O-ring is not twisted. Ensure that the
seat and O-ring are clean.
(l) Torque the plug from 6 to 9 foot-pounds (0.8 to 1.2 kg-m). Do not over tighten the plug to
stop a leak, If plug leaks, remove it, and install a new O-ring.
(m) Recharge the system per Servicing the System, Charging, above.
(5) Adjustment of Drive Belt Tension
NOTE: An alternate method of checking belt tension is by measuring the torque required to
“slip” the belt at the small pulley. See Chart 8.
Adjust the A/C compressor belt tension as follows:
(a) Initial adjustment of a new belt requires a mid-span deflection of .31 IN. at 14 lbs. load.
(b) Service adjustment of a used belt is a mid-span deflection of .31 IN. at 10 lbs. load.
