5.5.4.3 Attentions for Removing the Valve Plate
Dropping of the valve plate may cause injury or damage to the compressor.
Always attach the stud bolts before performing the work.
If the stud bolts that are used for removing
the head cover are already removed, attach
the stud bolts into the head cover screw bolt
holes for two sections at the top, then
remove the valve plate.
To remove the firmly–retained valve plate,
insert the valve plate screw into the service
hole (a) and tighten it.
5.5.4.4 Attentions for Removing the Piston Assembly
1.
Attach the bolt (M20) (a) and nut (b) to the
crankshaft.
Use the set bolts (M27 with fine pitch) for
62M-FM.
2.
Using the bolt (M20) (a), rotate the crankshaft so
that the piston assembly to be removed is
positioned at the bottom dead center.
3.
Remove the piston assembly using the suction
disk (c).
Verify that the suction disk is firmly
stuck to the piston assembly. If the
suction disk is not stuck firmly, the
piston assembly may fall, resulting in
hand or physical injury.
5.5.4.5 Attentions for Attaching the Cylinder Sleeve Assembly
1.
Align the sleeve positioning pin (a) with the
groove on the case (b).
2.
While keeping the pin aligned with the groove,
align the unloader push rod tab (c) with the cam
ring notch (d).
3.
To check the attachment condition of the cylinder
sleeve assembly, check the movement of the
unloader push rod (piston) when removing the
spacer used for the unloader maintenance.
(Refer to "Removal of the Spacer".)
