DECK BELT REPLACEMENT
(Refer to Fig. 25)
Major causes of belt failure are improper instal-
lation and tension. Before installing a new belt,
check spindle shafts and bearings for excessive
endplay and wear by moving each spindle shaft
side to side and up and down. Be sure they turn
smoothly and freely. Make sure idler is still
aligned with spindle sheaves. Check sheave
grooves for cleanliness and wear. If grooves re-
quire cleaning, use a cloth moistened with a
nonflammable nontoxic degreasing agent or
commercial detergent and water.
Avoid excessive force during installation. Do
not use tools to pry belt on or roll belt over
sheaves. This can cause hidden damage and
premature belt failure.
1. Position the mower deck in the lowest (1
inch) cut height setting and remove the left
and right belt shields.
2. Loosen the lock nut (A) and back off (counter-
clockwise) the draw nut (B) until tension is
released from the old belt (C) and it can be
lifted off the deck sheaves.
3. Install the new belt following Fig. 25 for
proper belt routing.
4. Reset the belt tension using the procedure
in the “Deck Belt Adjustment” section
page 34.
5. Re-install the left and right belt shields.
BLADE SPINDLE ASSEMBLY
REMOVAL
(Refer to page 36, Fig. 26)
1. It is not necessary to raise machine to remove
the blade spindle assembly.
2. Raise the mower deck to the highest position
and place the height adjustment pin in the 5
inch cut height hole.
3. Remove blade, deflector cone (15) and
washer (14). Be careful handling sharp
blades. Used protective material and block
securely when removing blades.
4. Lower mower deck to the lowest (1 inch) cut
height with height adjustment pin in the 1 inch
cut height hole.
5. Raise the footrest and remove belt shields.
6. Remove deck belt. See Deck Belt Replace-
ment section above.
7. Remove the top bolt (2) and cup washer (3)
from the spindle sheave (1).
8. Mark spindle sheave (1) on the topside so it
will not be installed upside down on re-as-
sembly.
9. Remove the spindle sheave (1) with a wheel
puller. Make note if you remove any spacers
or washers not shown in the illustration, as
they will need to be reinstalled as they were
removed. Spindle shaft (9) may fall out of the
spindle assembly to the ground after remov-
ing sheave.
10. Remove square key (16) and bearing shield
(4) and save for re-assembly.
11. Remove spindle assembly by removing the
