MAINTENANCE
HYDRAULIC PUMP DRIVE BELT
REPLACEMENT
1. Park the rider on a smooth, level surface such as
a concrete floor. Disengage the PTO, engage the
parking brake, turn off the engine, and remove the
ignition key.
2. Remove the PTO drive belt (see MOWER BELT
REPLACEMENT for removal instructions).
3. Loosen the nut towards the front of the machine on
the spring anchor hook (H, Figure 39) to release
the majority of the belt tension. Use caution and
remove the nut to completely release the tension.
4. 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 pump pulleys
(B & C).
5. Reinstall the anchor hook (H) into the anchor tab
and loosely fasten the nut. Adjust the spring until
a measurement of 7-3/4” (19,7cm) is achieved
from the outside of the spring hooks. Tighten nut.
6. Reinstall the PTO drive belt.
