4-6-3-7. ASSEMBLY
Paying particular attention to the following points,
reassemble the parts by reversing the procedure for
disassembly.
(1)
GOVERNOR VALVE AND
VALVE SHAFT
(1)
Coat bearing with bearing grease, and assemble
valve shaft, bearing, bearing screw on body.
(2)
Place body with its mounting flange upward, and
also place valve shaft with its recessed portion upward
on a work table.
(3)
Place valve on shaft in such a position that
projection of valve will coincide with hole in stabilizer.
and temporarily tighten valve on shaft with washer and
screw.
(4)
Adjust position of valve in such a way that. when
valve is fully closed, clearance at both ends of major axis
is zero, and clearance at both ends of minor axis will be
of equal value. Then finally tighten valve on shaft. See
Fig. 6-23. After assembly, make certain that shaft
rotates with ease.
