DISASSEMBLY
Caution:
Wash the outside of the injection pump. Clean the work bench and workshop before operation.
Always measure and record the pump injection volume characteristics before disassembly. This
information gives a clue as to the cause of any adjustment error or defective parts.
While disassembling parts, check how they were installed and check them for any sign of
deformation, damage, roughening and scratches.
Arrange the removed parts in an orderly manner and distinguish parts to be replaced from those
to the reused.
