DISASSEMBLY
Since the regulator consists of small
precision finished parts, disassembly and
assembly are rather complicated.
For this reason, replacement of a regulator
assembly is recommended, unless there is
a special reason, but in case disassembly is
necessary for an unavoidable reason, read
through this manual to the end before
starting disassembly.
(1)
Choose a place for disassembly.
Choose a clean place.
※
Spread rubber sheet, cloth, or so on on

top of work-bench to prevent parts from
being damaged.

regulator with clean oil.

Remove hexagon socket head screw
(412, 413) and remove regulator main
body from pump main body.

※
(4)
Remove hexagon socket head screw
(438) and remove cover (C,629)
