Part 1024496_06
This part provides sequential pump disassembly procedures. Unless
otherwise noted in the Special Reassembly Instructions, which are provided
in each procedure, reassembly of the pump is the reverse of the
disassembly.
Within each disassembly procedure, is a check/repair table that describes
what specific conditions (from Table D‐1) to inspect for while disassembling
the pump, service details, and component part numbers.
The melter must be brought up to operating temperature before the pump
can be removed and disassembled. Once the pump is removed, the molten
material within the pump will remain workable only for a short period of time.
If necessary, use a heat gun to warm the pump assembly during
disassembly.
