4. Loosen the nut on the spring anchor eyebolt
(G, Figure 44) to release the majority of the belt
tension. Use caution and remove the nut to
completely release the tension.
5. Remove the old belt and replace it with the new
one. Make sure the V-side of the belt runs in
the grooves of the crankshaft pulley and the
transmission pulleys (B & C).
6. Reinstall the spring anchor eyebolt (G) into the
anchor tab and loosely fasten the nut. Adjust
the anchor eyebolt until a measurement of 5-7/8”
(14,92 cm) is achieved from the outside if the
spring hooks. Tighten nut.
7. Reinstall the PTO clutch to the engine crankshaft
and secure with the crankshaft bolt. Tighten the
crankshaft bolt to 65 ft. lbs (88 Nm).
NOTE: Make sure that the slot in the PTO clutch
lines up with the PTO clutch mounting tab (A, Figure
43) underneath the engine deck.
8. Reinstall the PTO drive belt.
