PTO Pulley and Engine Pulley Alignment (Fig. 6, 7)
1. Lower the implement to the shop floor, turn the engine
off, remove the key from the ignition switch and engage
the parking brake.
2. Move the P.T.O. lever to the ON position to move the
pulley away from the brake. Remove the locknut holding
the brake onto the mounting pin, and slide the spacer,
brake and spring off of the pins.
3. Loosen the setscrews in the lock collars at the front
and back of the P.T.O. shaft. Using a punch and ham•
mer, loosen the collars by driving them in the opposite
direction of the normal shaft rotation. The P.T.O. shaft
and P.T.O. pulley assembly should now be free to slide.
Figure 6
4. Using a straight edge, line up the top of the engine
pulley, with the top of the P.T.O. pulley. When the top of
the pulleys are aligned, the bottom of the pulleys are
misaligned by three degrees. Move the P.T.O. pulley
until its top is in line with the top of the engine pulley.
Then lock the pivot shaft and pulley in place by tighten•
ing the lock collars in the normal direction of shaft
rotation. Check the alignment of the pulleys again to
assure that the alignment did not change when the
collars were tightened. If alignment is still correct,
tighten the lock collar setscrews.
5. Slide the spring onto the large brake mounting pin.
Then slide the brake onto the mounting pin and the small
locating pin.

secure all parts in place with the locknut. Tighten locknut
