6.Replace damaged or worn fan with a new one. If during fan removal the key (#915) 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.)

E. Changing V-Belt
1.Turn off engine. Remove Spark Plug Wire from Spark Plug. Chock or block wheels of vacuum to prevent it from rolling.
2.Remove Debris Bag from vacuum.
3.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.”
4.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.
5.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.
6.Press down on Belt Tension Lever and lift V Belt off its pulley. Release Belt Tension Lever. Remove V Belt from Engine Pulley.
7.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.
8.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.
9.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.
