emission control devices and system may be
performed by any non-road engine repair
establishment, individual or authorized service
dealer.
In order to assure peak performance of your engine,
inspection of the engine exhaust port may be necessary
after 50 hours of operation. If you notice lost RPM, poor
performance or general lack of acceleration, this service
may be required. If you feel your engine is in need of this
inspection, refer service to any non-road engine repair
establishment, individual or authorized service dealer for
repair. DO NOT attempt to perform this process yourself
as engine damage may result from contaminants
involved in the cleaning process for the port.
7. Ensure the tips on tines are aligned in the same
direction with each other before reinstalling the clevis
pins and pin clips. See Figure 21.
8. Repeat this procedure on the opposite side.
NOTE: When installed correctly, there will be an "R" and
"L" tine on both the gearbox and the tips of the
tines. These letters will line up in the same
direction for each side. It is important that the
tines are installed correctly.
