6a Servicing the Pump
This section details servicing the pump for all models listed in this manual. Refer to the
sections for you particular pump only. Before beginning the removal process, you may
want to sketch (or photograph) the plumbing and component configuration to aid in
easy re-assembly.
6A.1 GENERAL PREPARATION
❑ Review heading “Before You Begin...” on page 79. Also review head-
ing “Cleaning and Inspection Guidelines” on page 82. Also review
WARNINGS ! note on pape 80.
❑ Remove valve operators, discharge and suction piping and valves that would
interfere with pump servicing.
Have clean disposable shop rags and oil dry handy. Also disconnect cooling
tubes from the water manifold and pump, air lines, electrical switches and
tachometer cable as needed.
❑ Drain oil from the gearbox - remove the magnetic pipe plug. See Section 4:
Preventive Maintenance, heading “Change Gearbox Oil” on page 63.
If your unit uses a pedestal mount, drain oil from the pedestal. See Section
4: Preventive Maintenance, heading “Change Pedestal Oil” on page 64.
Have a suitable container available to collect fluid. For gearbox capacity, see
“Appendix C1: Lube and Sealant Specifications” on page 139. For pedestal,
the reservoir holds approximately three (3) pints (1.4 liters).
❑ Always use proper lifting and support apparatus (jacks, hoists, straps, chain,
etc.) when servicing the unit. Exercise care when using chains to protect fin-
ished surfaces from scratches.
❑ Whenever the bell housing (flywheel) adapter is removed, match mark the
location of any shims between the bell housing and the engine flange and
assure they are replaced at reassembly. Also see Section 7.5 “Check Fly-
wheel Run Out” on page 129.
