REPLACEMENT AND SERVICING
SELF-PROPELLED DRIVE BELT
NOTE: After the belt has
been re-
moved, examine for broken, cracked or
misaligned pulleys. The condition and
the wear pattern of the belt will pro-
vide clues for the above possibilities.
Replace damaged or worn pulleys.
7. 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 premature
wear of the drive belt will result.
NOTE: Apply OMC Ultra-Lock Part No.
388517 to threads of set screw prior to
installation.
8. 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.
