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.

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.

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.
