7. Adjust clearance between armature plate (1) and magnet clutch pulley by putting shim(s) on compressor shaft. To measure the clearance, perform the following steps.
a. Put compressor in a vise (2).
b. Set dial gauge (3) on armature plate, and then adjust its pointer at O.
c. Connect battery positive terminal (+) to magnet clutch coil lead wire.
d. Connect battery negative terminal (-) to compressor body assembly. (At this point, armature plate and magnet clutch pulley are kept in contact.)
e. Disconnect battery negative terminal (-) to compressor body assembly. (At this point, armature plate and magnet clutch pulley are not in contact.)
f. Read stroke of armature plate from dial gauge by performing step d) and e) repeatedly.
(Stroke of armature plate is clearance between armature plate and magnet clutch pulley.)
Standard clearance between armature plate and magnet clutch pulley:
0.3 - 0.5 mm (0.012 - 0.020 in.)
