Section 3, "Pump Preparation, Operation,
and Maintenance," addresses the issues of
preparing the pump for operation after
shipping or storage, the lubrication system
design and specifications, the new pump
run-in procedures, and the periodic routine
maintenance schedule. The recommended
oils, viscosity data, and crankcase oil
temperature
requirements
are
also
presented in this section.
Section 4, "Service Procedures," describes
the
various
assembly
/
disassembly
procedures.
Section 5, “Trouble–Shooting,” describes
possible problems, causes and solutions
related to pump performance.
Section 6, “Rebuilding Data, Recommended
Running Clearances and Torques,” presents
information useful for pump rebuilding and
assembly,
including
dimensional
and
tolerance data, running clearances for all
bearings,
and
recommended
fastener
torques.
PUMP DESIGN
The GD 3000 pump uses three major
assemblies: power end, fluid end, and gear
reduction unit. The pump is designed with a
modular concept. Each assembly is a
module that can be assembled, handled,
installed, fixed, or transported separately
from the rest of the pump (See FIGURE 2-
1, page 9). The following is a brief
description of the essential design features
for each modular assembly.
POWER END (FIGURE 2-2,FIGURE 2-3)
The power end was designed utilizing cast
frame members joined by welded sections
to provide stiffness and strength. By
combining
cast
components
with
weldments,
the
GD
3000
provides
maximum durability with minimum weight.
