REMOVING THE FAN AND
REINSTALLATION
Remove spark plug wire from spark plug.
Remove nozzle assembly.
Remove front plate assembly.
Remove the bolt that secures the fan to the
engine crankshaft.
The fan has a 3/4-16 nut welded on the fan hub.
Insert a 3/4-16 x 5" long grade 5 (or better) bolt and
jack or push the fan off the engine. (CGC, Inc. P/N
910505 pressure screw is recommended.)
Replace damaged or worn fan with a new one.
If during fan removal the key (#64164-13) was
removed from the keyway, reinstall it by applying a
few drops of the Loctite 380 instant adhesive (“Black
Max” P/N 38050) on the key, and load the key in the
keyway of the shaft. (Cure time is approx. 1 min.)
Use a new bolt (#64123-127) (add Loctite 242 to
new bolt) and washer (#910527) and complete fan
installation. Insure a secure fit upon re-assembling.
Torque bolt to 39-51 Ft. lbs.
CHANGING V-BELT
Turn off engine. Remove Spark Plug Wire from
spark Plug. Chock or block wheels of vacuum to
prevent it from rolling.
Remove Debris Bag from vacuum.
Remove 3 hex head bolts that attach Belt Guard to
Deck. (Use 7/16” wrench or socket.) Set Belt Guard
aside.
Note how V Belt goes around each of 4 pulleys
and how it “twists.”
Remove 4 hex head bolts that attach Recoil Starter
Cover to Engine Standoffs. (Use 8 millimeter nut
driver, socket or wrench.) Remove Recoil Starter
Cover.
Loosen (but do not remove) 2 hex head bolts that
attach Fixed Idler Bracket to Deck. (Use 7/16”
wrench or socket.) This allows clearance for belt to
be removed.
Press down on Belt Tension Lever and lift V Belt off
its pulley. Release Belt Tension Lever. Remove V
Belt from Engine Pulley.
Remove V Belt from large horizontal pulley of
transaxle (under Deck.) Pushing V Belt forward
with both hands, then lifting V Belt up, then pulling V
Belt backwards should remove it from large pulley.
Remove V Belt from under Deck.
Reverse above steps to replace V Belt. Install V
Belt with the same “twists” that the old V Belt made
around the pulleys. Make sure the “V” side of the
V Belt goes into each pulley. Before replacing Belt
Guard or starting engine, pull Recoil Starter Handle
several times to make sure V Belt rides in the
grooves of each pulley.
Make sure Belt Tension Lever and return spring
operate smoothly. If it sticks or does not operate
smoothly, lubricate the Belt Tension Lever and its
mounting bracket with a few drops of Motor Oil, or
other medium weight oil. Push Belt Tension Lever
down and release it several times to allow lubrication
to penetrate between lever and mounting bracket.
Proper operation of the Belt Tension Lever and its
return spring will insure that your V Belt will operate
properly and last many hours of use.
