SLOP packaged in one carton.
For ease of attachment follow the step; outlined
below.
1. Mount “V” pulley to shaft of bevel gear assemble
( see figure 1 ) and secure in place with key and set
screw. Hub of
“V” pulley is to face inward. Place
drive belt on
“V” pulley and mount belt guard support to.:
inside surface of side plate nearest drive pulley. See‘
figure 5 for mounting bolt location. Attach the
~belt.
guard to the guard support as shown in figure 1. Allow
approximately 3/16” clearance between belt and hard;:

2. Holding the power take-off assembly in left hand
as shown in fieure 2. oosition the tube of the drive
bracket assembly b&&n the bevel gear housing
side plates. Align the holes in side plates with the
hole in drive bracket assembly tube and insert
pivot pin through holes in side plates
and drive
bracket assembly tube.
3. Push pivot pin through the holes in bracket and
tube until the position of cotter pin hole in pivot
pin is as shown in figure 3. Secure in position with

5. Mount “V” belt in place on driven pulleyas shown
in figure 5 and attach spring to b&am hole in the
spring holder and hook other end of the spring to the
idler lever spring holder. Mount belt stop as shown
with 3/S” bolt, flat washer, lockwasher and hex nut.
When idler pulley is engaged, l/S” clearance between
belt stop nud back of “V”beltis required. Note: “V”
‘belt ru”s uode,r idler pulley. See figure 5.

LUURICATION
The power take-off is lubricated by means of one
grease fitting located on the bottomfront
ofthe drive
‘bracket assembly. Occasionally apply grease by
means of a standard grease gun loaded with auto-
motive type grease. Be sure to wipe dirt and grit
from grease fitting before applying grease gun. Lu-
bricate all pivot points and idler pulley bearings with
SAE 20 oil every few hours of operation.
OPERATION
Operation of the power take-off is controlled by
m”veme”t of the clutch lever assembly. See figure
4. When the clutch lever is in the forward raised
position, the clutch rod releases the tension holding
the idler pulley against the drive belt, and power
will not be transmitted to the driven pulley of the
power take-off assembly. when the clutch lever iS
ia the back, depressedposition, theclutchrodapplies
tension to the idler pulley and as the idler pulley
takes-up the slack in the drive belt, power is trans-
mitted from the drive pulley on bevel gear box shaft
to the
drive” pulley of the power take-off. Figure 4
shows clutch lever in drive position.

ADJUSTMENT
At points “A” and “B” of figure 4, check tightness of
hex nut to be sure that clutch lever assembly and
clutch rod are free to pivot without binding.
Place clutch lever in “drive” position and observe
clearance between collar “C” (figure 4) and end of
bracket. This clearance should normally be ap-
proximately 3/4 inch; at this setting the idler pulley
should be snugly against the drive belt. If additional
tension is required, release clutch lever and loosen
set screw on collar andslide collar farther back on
clutch rod. Retighten set screw in collar and put
clutch lever in drive position. Recheck clearance.
The tension of the idler pulley against the drive belt
must be sufficient to operate whichever tractor at-
tachme@ is being used. ,Any additional tension iS
unnecessary and will only cause premature failure
of belts and idler pulley bearings.
