17.1BLADE REMOVAL / SHARPENING
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: 5/8 inch socket, torque wrench, adequate support.
1. Disconnect spark plug wire.
2.Support front of unit to allow access to the blade. Note: Unit is heavy. Be sure support is adequate to prevent personal injury.
3.Block the blade to prevent it from rotating during removal.
4.Remove the blade bolt (Item 139), lockwasher (140), and large friction washer (54).
5.Remove the blade (50) and, replace or sharpen the blade.
NOTE: When replacing the blade use only B.G.I. Part no. 500210.

17.2BELT REPLACEMENT
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 replace- ment. 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.
Transaxle Drive Belt
Tools required: 1/2 inch socket, 1/2 inch universal extension bar, pry bar or long screw driver, adequate support for machine.
1.Disconnect spark plug wire.
2.Support rear of unit to allow access to underside of the machine
towards the rear. Note: Unit is heavy. Be sure support is adequate to prevent personal injury.
3.Loosen but do not remove the two nuts (116) holding the plate mount idler (item 26) in place. This will release the tension on the blade drive belt (29). NOTE: It may be necessary to apply some force to the pulley to slide it over from it’s tight position and release the belt.
4.Working from the underside of the machine, loosen but do not remove the four screws (103) holding the two belt guides(Items 149 & 150) in place next to the crankshaft drive pulley (9) at the rear of the machine. This will loosen the belt guides(Items 149 & 150) and allow them to move to the side. NOTE: This step requires the use of a universal joint or universal extension bar to reach the screws(103) holding the belt guide(149). If universal joint is not available you may remove the “neutral stop bolt”(Item 115) and associated nuts (116 & 117) to allow the idler arm to swing back and allow access to the screws(103) holding the belt guide(149).
5.With the guides loose slip the transaxle drive belt(Item 10) out of the groove on the drive pulley and down past the pulley.
6.Slip the old belt(10) up and over the pulley on the transaxle (Item 9) and remove belt from machine.
7.Install new belt in groove on transaxle pulley(Item 9) and slip into groove on transaxle drive pulley(46).
