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. If pump is
furnished with pressure relief valve, it need not be
removed from head or disassembled at this point.
Refer
to Pressure Relief Valve Instructions, page 11.
If LS pump has jacketed head plate, it will separate from
head when it is removed. The gasket between head and
jacket head plate must be totally removed. Use new
gasket when assembling pump.
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 remove
locknut and lockwasher from shaft.
4. Remove packing gland nuts.
5. Tap shaft forward approximately 0.5 inch and remove
pair of half round rings under inner bearing spacer
collar.
6. Carefully remove rotor and shaft to avoid damaging
bracket bushing.
7. Remove packing gland from side of bracket.
8. Loosen four setscrews over the inner and outer end
caps. Remove both end caps with lip seals, spacer
collars and ball bearing.
