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.
