DISASSEMBLY AND ASSEMBLY
General Cautions
• Carry out disassembly and assembly operations
in a clean place and provide clean containers to
place the disassembled parts in.
• Before disassembly, clean around the ports and
remove the paint from each joint using a wire
brush.
• Clean each of the disassembled parts with a clean-
ing oil such as diesel fuel.
• Make match marks on each part so that they will
be assembled in the same positions when as-
sembled.
• Replace all seals with new ones each time the
pump is disassembled, coating them lightly with
grease.
• Check each part to make sure there is no abnormal
wear or seizing and use sandpaper, etc. to remove
any burrs, sharp edges, etc.
• Adjust adjustment screws only when required.
