PTO SEAL
Inspection
Check the PTO seal no. 22 and O-rings no. 10 on
the PTO housing. If brittle, hard or damaged, or if
you see a sign of oil leakage, replace it.
Removal
NOTE: When drive shaft will be removed, some
oil will flow out. To prevent it, start engine, run at
4000 RPM for 10 seconds and stop engine at this
RPM. This will move oil out of PTO housing into
oil tank.
CAUTION: Never run engine without supplying
water to the exhaust cooling system when wa-
tercraft is out of water.
Place rags under PTO housing to prevent spillage.
If spillage occurs, clean immediately with the pul-
ley flange cleaner (P/N 413 711 809) to prevent oil
stains.
Remove:
– Oetiker clamp no. 11 located close to the PTO
housing
– jet pump (refer to JET PUMP in PROPULSION
SYSTEM)
– drive shaft (refer to DRIVE SYSTEM in PROPUL-
SION SYSTEM)
– PTO seal no. 22.
