WARNINGS !
BEFORE WORKING ON THE PUMP, DISCONNECT SUCTION AND DIS-
CHARGE PIPING AND DRAIN THE PUMP BODIES.
THE HALE PUMP AND GEARBOX ASSEMBLY CAN BE HEAVY AND BULKY.
ADDING ACCESSORIES ALSO INCREASES THE WEIGHT. CHECK YOUR
BILL OF LADING FOR THE APPROXIMATE WEIGHT. BE CERTAIN TO USE
PROPER LIFTING SUPPORT DEVICES (I.E., OVERHEAD CRANE, JACK,
CHAINS, STRAPS, ETC.) CAPABLE OF HANDLING THE LOAD WHEN
REMOVING OR INSTALLING THE PUMP AND GEARBOX ASSEMBLIES.
BE SURE TO WEAR SAFETY GLASSES WHEN REMOVING AND/OR INSTALL-
ING FORCE (PRESS) FITTED PARTS. FAILURE TO COMPLY MAY RESULT IN
SERIOUS EYE INJURY.
ALL FASTENERS ON THE HALE PUMP AND GEARBOX ASSEMBLY HAVE
BEEN SELECTED FOR THEIR APPLICATION. HALE PRODUCTS DOES NOT
RECOMMEND REPLACING FASTENERS WITH ANYTHING OTHER THAN
HALE PART NUMBERS PROVIDED. REPLACING WITH A WEAKER ALTER-
NATIVE POSES A SERIOUS SAFETY RISK.
ALL FASTENERS MUST BE INSTALLED WITH A LOCKING ANAEROBIC
ADHESIVE/SEALANT, SUCH AS LOCTITE® #246 FOR GEARBOX AND #242
FOR PUMP.
5.
Remove necessary body panels and framework to gain access to the
pump compartment and pump and gearbox assembly.
6.
When necessary, remove valve operators, discharge and suction piping
and valves that would interfere with pump removal.
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 required.
7.
Where grease is called for, use a Lithium-based grease with 1% to 3%
Molybdenum Disulfate. For a listing, see Section “Appendix C1: Lube
and Sealant Specifications” on page 115.
Also see Section 4: Preventive Maintenance, heading “Replace Gear-
box Oil” on page 52.
8.
When replacing fasteners, use the proper nuts, bolts, and other hard-
ware. Also ensure screws/bolts are properly torqued where required.
(See Table 6-1: “Typical Torque Values Chart,” on page 69.)
Many are specifically rated; that is, SAE Grade 5 or higher. Unless oth-
erwise specified, fasteners are Grade 5 SAE.
