FABRICATED
TOOLS
These drawings provide a means by which simple tools can
be made to assist in the removal
of
the generator end from
the engine and in the replacement
of
the generator end on the
engine. A local machine shop should
be
able to fabricate these
tools at a modest price, but first check with your local WEST-
ERBEKE dealer to see
if
these tools are
on
hand for loan.
Housing
Puller
Tool
This tool allows the bearing in the generator housing to be
gently pushed straight off the housing without any twisting.
If
a nut
of
the same specifications as that
of
the tapped hole
in the pilot tool were to be welded
on
the end
of
the eye bolt,
this tool would be able to pull the bearing back into place
without any twisting. Please refer to these drawings before
the generator end is removed.
