b.
Install the bearing and cup (37) into its bore in the PTO housing (44). Press or tap the bearing cup (37)
squarely into its bore to bottom on its back face.
c.
Install the two dust protectors in their holes at the rear of the PTO housing.
d.
Install the passage plug (38) in the PTO housing (44) if removed during disassembly.
e.
With the PTO housing setting on the bench with the clutch end facing up, install the operating shaft (47)
and throwout yoke (50). Push the operating shaft halfway into the PTO housing (44). Slip the throwout
yoke (50) onto the operating shaft (47) and then push the shaft (47) the rest of the way through the
PTO housing (44) to its normal position. Be sure the throwout yoke (50) is installed so the capscrews
(49) enter from the clutch side toward the rear. Slide the yoke (50) to one side to expose Woodruff key
slot in the shaft (34) and install the key (48). Slide the yoke (50) to the other side and install the
remaining key (48). Center the yoke (50) over the keys (48) and secure the yoke (50) to the shaft (34)
with the two hex-head capscrews (49). Tighten the capscrews (49) to 30-42 ft-lb. torque.
f.
Using an arbor press and steel tubing, press the two bearings (36) onto the clutch shaft (34), one from
each end, with their back faces butting against the stop shoulder on the shaft (34).
g.
Install and secure the hand lever (42) to the operating shaft (47) with the hex-head capscrew (43).
Tighten the capscrew to 86-95 ft-lb. torque.
h.
Install the clutch shaft (34) with bearings attached into the shaft bore and bearing cup (37) in the PTO
housing (44); install the output end of the shaft-(34) first. Slide the bearing cup (32) over the shaft and
into its bore in the PTO housing. Squarely press the bearing cup (32) in place against the bearing.
Install the bearing retainer (31) over the shaft (34).
i.
Adjust the bearing end play to 0.004-0.007 inch on the SP111 HP2 (0.006-0.010 inch on the SP 214
P1).
NOTE
o The only approved method of field adjustment is by the use
of a dial indicator to read actual end play. The
adjustment procedures are the same for both PTOs (except
for end play measurements).
o If only bearing adjustment is being made, remove the PTO
from the engine (paragraph 3-38).
