5.2 ASSEMBLY B
Assembly B should be replaced whenever Assembly A is replaced, or every 6 to 12 months for
optimal pump performance. The following instructions will guide you through disassembly and
reassembly of Assembly B, shown on the following page in Diagram B. To begin disassembly
and reassembly of Assembly B, you will need the following tool:
. (1) Assembly B installation tool (ships with spare Assembly B)
1. Use the installation tool, as oriented in Diagram B, to press Assembly B out from the center
block.
2. Inspect all components. If necessary, a spare Assembly B can be ordered for replacement.
Refer to Section 8.0 for spare parts.
3. To reassemble Assembly B, begin by pressing one shaft bushing into the center block until it
is flush with the outer face of the center block. Refer to Diagram B as needed for the following
steps.
4. Place the shaft seal ring in the recessed groove at the end of the installation tool. Then place
the shaft o-ring around the shaft seal ring. Apply small amounts of food grade lubricant on the
O-ring. Carefully press the seal ring and o-ring into the center block until both rings contact the
inserted shaft bushing.
5. Press the second shaft bushing into the center block. Ensure both shaft bushings are flush
with both faces of the center block.
