Disassembling the Pump
1. Mark head and casing before disassembly to insure proper
reassembly. The idler pin, which is offset in pump head, must be
positioned toward and equal distance between port connections to
allow for proper flow of liquid through pump.
Remove head from pump. Do not allow idler to fall from idler pin.
Tilt top of head back when removing to prevent this. Avoid
damaging head gasket.
2. Remove idler and bushing assembly.
3. Insert length of hardwood or brass through port opening between
rotor teeth to keep shaft from turning. Bend up tang of lockwasher
and with a spanner wrench.
4. Loosen Allen head setscrews in the face of the thrust bearing
assembly. Remove the thrust bearing assembly by threading out of
the bracket.
