ASSEMBLING OUTPUT SHAFT ASSEMBLY (85)

INTO UPPER GUARD GEARCASE ASSEMBLY (33)

To prevent damage to the Felt Seal (30) it is recommended to temporarily

remove the felt seal until steps 1 and 2 are completed.

1. With the use of both hands, compress the Spindle Lock Spring (31)

back on the Spindle Lock Plate (32) past the small hole on the plate.

2. While holding the spring back with one hand, quickly insert a thin metal

instrument into the small hole on the plate. The metal instrument

should capture the entire spring (all coils should be behind that tool).

With the spindle lock spring trapped behind the small hole on the

spindle lock plate, slide the felt seal back onto the spindle lock plate.

Position the felt seal above the corresponding cavity in the Upper

Guard Gearcase (33).

3. Insert the open end of the spindle lock plate (32) into the opening of the

Output Shaft Assembly (85) behind the gear, as shown.

4. Insert the bearing shaft portion of the output shaft assembly into the

needle bearing of the upper guard gearcase assembly. Carefully

wiggle the entire output shaft assembly until the gearing of the output

shaft assembly engages with the pinion gearing of the Rotor (81) and

the output shaft assembly slides into place.

Secure the output shaft assembly to the upper guard gearcase

assembly with the use of four screws (18), not shown. It is recom-

mended to alternate the tightening of the screws.

5. Remove the thin metal instrument. Check for the proper functioning

of the spindle locking mechanism. Rotate the spindle shaft and depress

the Spindle Lock Button (34) at the same time. The spindle lock plate

should drop into one of four cogs that lock the spindle. Spindle lock

mechanism must return briskly when released from engagement in the

lock block cog.

Detail 'A' shows Spindle Lock Spring (31) and

Felt Seal (30) in place in the respective cavities

of the Upper Guard Gearcase Assembly (33).

NOTE: The spindle hub and gear of the Output

Shaft Assembly (85) are not shown for clarity,

so the four Locking Cogs of the Lock Block can

be seen.

LUBRICATION

Type 'J' Grease, No. 49-08-4220

Apply 3.0 grams (.10 oz) of 'J' Grease to the

gear bore in Upper Guard Gearcase (33). The

grease should be directed toward the pinion end

of the rotor (81).

When servicing, remove 90-95% of the

existing grease prior to installing Type 'J'.

Original grease may be similar in color but

not compatible with 'J'.
