MAINTENANCE AND SERVICE INSTRUCTIONS
CLUTCH
FIGURE B
The clutch of the Rotary Snowplow is a double plate friction type mounted directly on
the drive shaft. With average use and care it will last indefinitely. However, extreme rough-
ness, exposure, and carelessness, will result in damage, therefore, the following instructions
are given for adjustment and repair.
ADJUSTMENT
Adjustment of the clutch is controlled by two nuts and two washers, one each on either
side of the spacer on the clutch control rod, Figure C, Illustrations 51 and 55. With the
clutch control lever in the disengaged position turn the adjusting nuts, Figure C, Illustra-
tion 37, on to the control rod far enough to release the clutch. The throwout lever, Figure B,
Illustration 51, should float between the two washers on the spacer when the control rod is in
the engaged position. The action of this clutch is approximately 3/64 of an inch. Each time
the Snowplow is removed and reattached to the tractor or if the drive belt is adjusted for
tension, the clutch must be readjusted. When using the tractor for belt work with the Snowplow
attached remove the drive belt.
CAUTION: Keep clutch adjusted properly to prevent Snowplow from slipping into gear. Keep
hands away from impeller, drive belt and chain, while engine is running.
After the Snowplow has been in operation for some time, the clutch facings, Figure B,
Illustration 43, may become glazed or covered with grease and oil causing slippage. To repair,
remove the facings (See instructions for removing as given under the Replacement and Repairs
Section of this Manual), and in the event of glazing, a good wire brushing, applied to the
facings will break up the glaze and restore normal operation. In the event a covering of
grease or oil causes the slippage, wash the facings in gasoline or kerosene and wipe dry. If
this does not correct condition, clutch facings should be replaced.
REPLACEMENT AND REPAIR
The following Illustration Numbers refer to Figure B unless otherwise stated.
FACINGS
To replace facings:
1. Disengage clutch.
2. Remove groove pin, Illustration 45.
3. Remove outer Clutch Plate, Illustration 41, Facing Illustration 43, and Pulley,
Illustration 52 by sliding from shaft.
4. Remove all burrs from the shaft.
5. Thoroughly clean all parts of grease and oil.
