Safety Introduction Disassembly Assembly
Preparing to Assemble the Pump
• Read and understand the instructions before assembling the pump.
• Prepare a workspace suitable to accommodate and support the pump.
• Gather the necessary tools and assembly aids.
•
Gather the necessary overhaul components, such as lubricant, bearings,
seals, and O-rings—only use equivalent components.
• Understand that your configuration may require additional steps that are not
described in the illustrations or instructions to perform the assembly.
• This equipment is intended to be assembled by a person or persons with the
basic knowledge of servicing similar equipment. Contact Waterous for more
information.
Tools Required
• Typical automotive mechanics hand tools.
• Suitable arbor press.
• Torque wrench capable of 200 ft-lb (271 N∙m).
• Suitable support and lifting equipment.
Best Practices
• Remove any dirt, sand, grease, or oil from the enclosure before you begin the
assembly. Surface debris can transfer into the pump interior and prematurely
wear internal parts.
• Replace any gaskets and O-ring seals during the assembly.
•
Do not reuse the self-locking nuts.
• Apply anti-seize to the self-locking nut threads before installation.
Optional Equipment
Be aware that the assembly instructions may include optional equipment not
included in your application.
Assembling the Pump Components
• Refer to the service parts list (SPL) for part identification.
• The SPL specific to your application is determined by the following:
• The transmission drive method.
• Whether the transmission drives a CAFS compressor.
Note: Documents specific to your application are available through the
MyWaterous login at Waterousco.com by entering the serial number for
your system. Depending on the application, the serial number for your
equipment is located on the operator panel, pump, transmission, or
some combination of the three.
• Use established industry practices to assemble the pump.
• Tighten hardware to industry standard torque specification—unless otherwise
noted.
•
Make sure that you do not over-tighten plugs.
• Install retaining rings with the rounded face toward the component you are
retaining.
• Replace items such as O-rings, bearings, gaskets, oil seals, lubricants, and
locknuts with their equivalent.
Installing the Pump
Use the information that you recorded when you removed the equipment to
install it into the apparatus.
Understanding the Illustrations
The assembly illustrations depict a typical application. Plugs, breathers, cooling
hoses, and fittings are not illustrated, as they may be in a different location on
your application. Refer to the SPL for your application to identify the various
plug locations .
