5.4.10 Oil Injection Pipe

Figure 5-17 Development view of the Oil Injection Pipe section
The unloader push rod protrudes from the location where the unloader cylinder of the suction
cover is removed, and the injection pipe is attached to the outer periphery of the unloader push
rod. Relaying the unloader push rod and slide valve from the suction cover, injection oil is
supplied to the rotor meshing part.
Disassembly
a) Remove the hexagon socket head cap screws (part number 166) that tighten the oil injection
pipe retainer (part number 164).
b) The oil injection pipe retainer has two screw holes for pull out. Use the eyebolt to pull it out
parallel to the unloader push rod. Since it is sealed with four "O" rings, so it needs a little force.
