Maintenance (continued)
Remove the shaft bolt, bolt guard,
■
holder A, blade, holder B, and
the output shaft collar. Press new
grease into the gearcase until the
old grease has been pushed out.
Use only lithium-base grease.
Inspect the Gearcase Protector
The metal gearcase protector
is installed
to protect the gearcase flange from
damage when working close to side-
walks or other abrasive surfaces, and
should be routinely inspected for dam-
age or excessive wear.
When replacing the protector, inspect to
be sure that both of the protector mount-
ing 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 vibration 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 3.
assembly from the shaft tube.
Pull the flexible shaft from the shaft
4.
tube assembly, and clean the shaft
thoroughly in solvent.
Inspect the shaft carefully, and
5.
replace if worn or damaged. If flexi-
ble shaft is worn and needs replace-
ment, liner should also be replaced.
Coat the entire length of the shaft
6.
with a premium gearcase lube and
reinstall the shaft in the shaft tube
assembly.
Insert the flexible shaft into the
7.
female end of the gearcase pinion.
NOTE:
For extended shaft life, the flexible
cable should be reversed end-for-end
during the reinstallation process.
