4.2 Rotor Casing (1), Unloader Slide Valve (54), Variable Vi Slide Valve (289) and Bearing Head (11)
a) Unloader slide valve (54)
Confirm that the Vi changing rod (444) moves properly. Mount the unloader push rod (67) and
fit the gasket to the hole for the Vi changing rod shaft.
b) Rotor casing (1)
Clean the oil injection holes thoroughly, fit the plug (10) and mount the unloader slide valve
(54). Confirm smooth movement of the unloader slide valve.
c) If the rotor casing (1) and bearing head (11) have been separated, assemble them now
(normally, these two parts are not disassembled). Tighten the bolts (2) to the specified torque
in a symmetrical crisscross pattern. A number of the bolts on the bottom cannot be accessed
at this time and must be tightened later when the compressor is raised.
