Specialty Tools
Overhauling the Sundyne LMV 313 pump in the
field requires a couple of specialty tools that are
not generally needed while overhauling other
Sundyne models. These specialty tools are
recommended in order to simplify the overhaul
procedure. These tools also provide more
consistency in the setting of the high speed shaft
loading and clearances. The following section
will provide details on manufacturing these tools
in the field as well as the use of these tools.
Shaft Loading Tool
The shaft loading tool is used to preload the
shaft against the lower thrust bearing with an
approximate 1000 pounds (453.6 kg) end load.
This removes slack from the bearing stack-up. It
also allows for more consistency in adjusting the
impeller and inducer housing shims. See the
following figures for details.
Pumps using the tapered inducer configuration
do not require tool items 6, 7, and 8. This is due
to the diffuser in these machines being bolted to
the seal housing. To apply preload to the shaft,
lay tool detail 1 across the open end of the
inducer housing. (Refer to figure 19.)
It is vital that the mating surfaces of the diffuser
and the seal housing are clean. Any high spots
caused by nicks and dings must be removed so
that errors will not be introduced during
shimming and reassembly.
