Isolation Mount Operation (cont'd)
The system is constructed of
two
rubber cushions and a
cushion holder. The cushions are positioned between
the holder and the clutch housing and are actually the
only
two
points of contact between the engine and the
drive tube. This arrangement allows vibration to pass
only through the
two
rubber cushions and reduces the
amount
of
vibration that is transmitted
to
the operator.
Under normal circumstances, the Isolation Mount should
not require any maintenance for the life of the product.
However,
if
an increase invibration is noted, the cushions
should be inspected and,
if
found to be damaged or
compressed, should be replaced.
Isolation Mount Disassembly
1.
Remove the single locating screw and the
two
clamping screws that secure the engine to the
drive tube and separate the engine from the drive
tube. See Figure
82.

NOTE:
It
is not necessary to remove the throttle
linkage.
2.
Remove the two allen screws that secure the two
halves of the cushion holder and separate
the
halves.
3.
Inspect the rubber cushions for wear and damage.
Replace
if
necessary.
Isolation Mount Reassembly
1.
Position the rubber cushions on the clutch housing
as shown in Figure
83.
Figure

NOTE:
Good contact between the cushions and
the clutch housing is essential in minimizing
vibration. Therefore, bonding the cushion to the
clutch housing with a cyanoacrylate type glue
(Super Glue@) is recommended.
Place the
two
cushion holder halves around the
cushions
so
that the locating screw
is
on the
bottom side of the engine. Secure the cushion
holder with the two allen screws.
Position the engine properly on the drive tube and
secure with the locating screw and the two
clamping screws.
It
may be necessary to rotate the
cutter implement slightly in order to get the drive
shaft and the clutch drum to mate properly.
