Inspect the Gearcase Protector
The metal gearcase protector is installed to
protect the gearcase flange from damage
when working close to sidewalks or other
abrasive surfaces, and should be routinely
inspected for damage or excessive wear.
When replacing the protector, inspect to be
sure that both of the protector mounting
screws are firmly tightened and each screw
is locked in place with a nut as shown.

Lubricate the Flexible Shaft
Lack of lubrication will cause rapid wear
to the flexible shaft and also to the shaft
tube liner, resulting in increased vibra-
tion and greatly decreased service life.
Remove and lubricate the flexible shaft as
follows:
Loosen the gearcase clamp screw. 1.
Remove the gearcase index screw. 2.
Slide the gearcase and shield assembly 3.
from the shaft tube.
Pull the flexible shaft from the shaft 4.
tube assembly, and clean the shaft thor-
oughly in solvent.
Inspect the shaft carefully, and replace 5.
if worn or damaged. If flexible shaft
is worn and needs replacement, liner
should also be replaced.
Coat the entire length of the shaft with 6.
a premium gearcase lube and reinstall
the shaft in the shaft tube assembly.
Insert the flexible shaft into the female 7.
end of the gearcase pinion.
