SELF-PROPELLED BELT DRIVE
NOTE
After the belt has been removed,
examine for broken, cracked or mis-
aligned pulleys.
The
condition and
the wear pattern of
the
belt
will
provide clues for the above possibili-
ties. Replace damaged or worn
pulleys.
5.
The crankshaft pulley (drive pulley)
is
secured to
the
crankshaft
with
a
SPECIAL
slotted set screw. The end of
this
screw
locates in a hole in the crankshaft. The
correct position and tightness
is
very
IMPORTANT.
If
not tightened securely,
damage to the pulley, crankshaft and pre-
mature wear of the drive belt
will
result.
NOTE
Apply
OMC
Ultra-Lock (part no.
388517)
to
threads
of
set screw prior to installation.
6.
When reinstalling pulley to crankshaft,
the side of the pulley
with
set screw
is
the
lower side.
If
assembled upside
down
(set
screw on top) misalignment and interference
of pulley operation
will
result. Always
check
pulley for damage. Replace
if
necessary.
