Spindle Drive &
Drive Kit Assembly
For use on mowers equipped with 42", 48",
52" or 61" decks:
1. Remove the discharge chute.
2. Remove the right hand belt shield.
3. Remove the deck belt from the right spindle
assembly sheave.
4. Remove this sheave but keep the ¼" square
key and the two washers at hand for reinstal-
lation.
5. Install the Stepped Sheave and spacer/key
retainer included in the kit using the original key
and washers but substituting the original 7/16"
HCS with the longer version provided. An ap-
plication of anti-seize is recommended.
6. Reinstall the deck belt.
7. The 5/8" hole toward the rear of the ¼" thick
discharge chute mounting bar at the right end
of the deck may be distorted from forming or
loaded with paint. Drill out or fill this hole until it
will accept a 5/8" bolt or piece of bar stock.
Keep the fit close.
8. If any weld beads or the edge of the deck top
project past the right end surface of the deck,
these must be ground back to allow the fan
assembly to fit up flush to the end of the deck.
9. Remove the 3/8" fastener, nut, and clamp from
the inside front corner of the fan assembly.
10. Remove the sheave floor to expose the fan
assembly belt sheave from below.
11. Loosen the nut retaining the belt guide/retainer,
install the belt from the Drive Kit, retighten the
nut, verify the belt clears the guide, and reinstall
the sheave floor.
ASSEMBLY
12. Rest the fan assembly onto the deck end and
slide the pilot thru the 5/8" hole previously
mentioned so that fan assembly is supported
by the pilot and the ¼" stop block welded under
the clamp at the front of the fan assembly.
Note: It may be necessary to swing the
idler pulley away from the assembly
mounting face to clear the chute mounting
bar and the discharge chute mounting tab
on the deck.
13. Reinstall the clamp at the front of the assembly
so that the tab at the lower end of the clamp
passes thru the rectangular slot at the right
front corner of the mower deck, but leave the
fastener loose to ease belt installation.
14. Rotate the belt idler as far forward as possible
and install the belt over the top groove of the
new deck sheave.
15. Tighten the clamp fastener.
16. Using a scribe or other small sharp object,
transfer the mounting hole location at the rear
edge of the fan assembly onto the mating
vertical surface at the right rear of the mower
deck and drill thru with a 25/64" drill.
17. Install the stops on the deck stop pins located
at the rear of the deck then install the new belt
shield.
18. Install the tube support to the main collection
assembly using the 3/8" fastener provided, po-
sitioning so that the tube is 2" to 3" away from
the tire.
19. Install the 7" hose to the fan assembly and the
container input port using the hose clamps
provided.
20. Clamp the tube to the tube support.
