HOUSING-MOUNTED CLUTCH MAINTENANCE - The
"'ousing-mounted compressor clutch on the coach (figure
:3-50) requires bearing lubrication periodically after the
initial 5,000 miles (8,000 km). The frequency of lubrication
is once per year, 'in the spring when the air conditioning
system is being checked for operation. The point of lubrica-
tion is the grease fitting on the bearing retaining nut. Per-
form the following procedure to grease the bearing:
1. Open the two-way manual valve to vent air pressure
from the drive belt tension air cylinder.
2. Remove the two A/C drive belts from the compressor
clutch rotor.
3. Disconnect the coil electrical connector.
4. Insert tool 20-296 into two of the three threaded holes
in the armature. See figure
16-51.
This is to prevent the
armature from rotating.
