CLUTCH ADJUSTIvlENT
If the clutch begins to slip, it should be readjusted,
otherwise it will become overheated and damaged.
First remove the inspection plate which will expose
the notched adjusting ring. Release the clutch, by
pushing the engaging lever forward. Turn engine over
until the clutch ad[ustment lock is visible thru the
inspection opening. Loosen adjustment Iockscrew,
one full turn. Keep the engine crankshaft from turning,
then, by means of a screw driver as shown in Fig. 39.
turn the adjusting ring, one notch at a time in a clock-
wise direction, until a very firm pressure is required
to engage the clutch with the lever. Be sure that the
clutch cams snap over-center on final adjustment.
Securely tighten adjustment lockscrew. Assemble in-
spection plate, being sure that the gasket fits proper-
ly and is not broken.
CLUTCH REDUCTION UNIT
ADJUSTMENT
The clutch in the clutch reduction unit is the same
as used in the clutch take-off assembly. The clutch
adjustment is made thru two pipe tap openings; one
for the adjustment Iockscrew and the other for turning
the adjusting ring, as illustrated in Fig. 40. There
are four ½ inch square head pipe plugs in the hous-
ing, to provide a means of adjusting the clutch re-
gardless of what position the unit is mounted in.
Remove the two pipe plugs on the side of the hous-
ing (if not accessible, use the two optional taps).
Disengage the clutch and turn engine over slowly
with a hand crank until the adjustment Iockscrew is
visible thru the pipe plug opening nearest to the en-
gine. Loosen Iockscrew one full turn, or enough to
relieve the tension of the lock against the notches
on the adjusting ring. Then, turn engine over slightly
to expose the notches on adjusting ring. Keep engine
crankshaft from turning, while thru the adjacent pipe
plug opening, turn the adiusting ring with a screw
driver, one notch at a time in a clockwise direction
(viewing from take-off end), until a very firm pres-
sure is required to engage the clutch with the lever.
Tighten adjustment lockscrew and mount pipe plugs,
when adjustment is completed.

REDUCTION GEARS
Reduction gears are furnished with several different
ratios, some with spur gears, others with chains. All
are of the same general design, except that some are
furnished with clutches, others without, and for var-
ious installations can be mounted with the take-off
shaft in either a 3, 6, 9 or 12 o’clock position. Use
the same grade of oil in the reduction unit as is used
in the engine crankcase.
Several plugs are furnished so that lubrication may
be properly taken care of regardless of the position
of the installation. There will always be one plug on
top to be used for filling oil, a plug below for drain-
ing oil, and there will be one plug on the side slightly
above the bottom, to be used as an oil level plug.
See Fig. 41.
The oil should always be filled when the engine is at
rest. When the oil becomes dirty, it should, be drained,
while the engine is hot, and fresh oil added. The fre-
