17.1 BLADE REMOVAL / SHARPENING

17.2

BELT REPLACEMENT

NOTE: When sharpening the blade it is a good idea to check the balance of the blade. A properly balanced blade will increase life of the bearings and other components.

Tools required: 3/8 inch socket, 5/8 inch socket, torque wrench, blade block.

1.Disconnect spark plug wire.

2.Remove 5 screws (item 76) then remove belt guard (19).

3.Set the unit on its side to allow access to both pulley and the blade.

Note: When tipping the unit on its side, keep the air cleaner side of engine up. Be sure the gas is drained out to prevent from spilling before tipping the unit on its side. Never tip the mower more than 90 degrees and do not leave the mower tipped for any length of time.

4.While protecting your hands with pair of gloves or heavy rag to hold the blade, loosen but do not remove the bolt (88) on the pulley side (fig. 6).

5.Remove jam nut (68), blade washer (43), blade (44), blade washer (43), and blade spacer (39).

6.Replace or sharpen the blade then install in the exact order they were removed (fig. 7).

7.Tighten the jam nut until it is flushed with the end of the shaft (fig 7). Then tighten the bolt on the pulley side - Torque it to 80 ft-lbs.

Note: When replacing the blade use B.G.I. Part no. 510107.

8.Reinstall belt guard then connect spark plug.

Note: Before installing the fasteners inspect them for wear and replace as necessary.

When replacing one belt the other should be inspected for wear and replaced if worn. It is good practice to change both belts when either is worn beyond use. Use only original equipment belts for replacement. Billy Goat uses only premium quality, kevlar corded and coated belts in your unit. Substitute belts do not meet the design and performance requirements for your unit , and will greatly reduce machine performance and belt life.

Blade Drive Belt

Tools required: 3/8 inch socket, 1/2 inch socket, 3/8" torque wrench.

1.Disconnect spark plug wire.

2.Set the deck height to middle position (3 inches cutting height).

3.Remove 5 screws (item 76) then remove belt guard (19).

4.Loosen but do not remove the nut (71) at the top of the engine base located just front of the engine. This will release the tension on the blade drive belt (37). NOTE: It may be necessary to loosen bolt (85) in order to allow idler pulley bracket to pivot .

5.Replace the old belt with the new belt.

Note: Use only O.E.M. approved belt for this machine - B.G.I. Part no. 510139.

6.To adjust tension on the new belt, insert 3/8" torque wrench in the idler bracket, apply 10 lbs. of torque then tighten the nut (71) on top of the engine base (fig. 8).

Note: Belt requires very little tension to drive the blade. Over tensioning the belt will greatly reduce the life of the belt.

7.Install belt guard using 5 screws (76)

8.Reconnect spark plug wire.

Note: Start the unit up and cut grass to make sure the blade belt is not slipping.
