Compressor Coupling Installation
1.
Compressor Coupling or Clutch
2.
Key tapped flush with outside face of coupling. Do not tap key any farther into keyway.
3.
Torque bolt to 122 N•m (90 ft-lb)
4.
Washer
5.
Spray this area with corrosion inhibitor after assembling.
9.
Re-install the bolt and heavy flat washer and snug the bolt down by hand. Torque the bolt to
122 N•m (90 ft-lb).
10. Spray a corrosion inhibitor (such as spray paint) on the exposed part of the shaft and the
joint between the shaft and the coupling. This prevents moisture from wicking into the joint
and causing corrosion.
Compressors with Pressurized Seal Cavity
Starting in the first quarter of 2017, the pressurized seal cavity was phased into use on large shaft
four cylinder compressors. Compressors with a pressurized seal cavity can be identified by the
“P” on the seal cover as shown (
). The model number of the compressor has
been changed to X430P to signify the Pressurized Seal Cavity as shown (
). The
pressurized seal cavity uses a new compressor seal with a hex drive and a new crankshaft with a
hex drive collar. See
“Hex Drive Compressor Seal Replacement,” p. 103
for the replacement
procedure.
