Hydraulic Pump Drive Belt Replacment
1. Park the tractor 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 53) 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.
