17MAINTENANCE
Use only a qualified mechanic for any adjustments, disassembly or any kind of repair .
WARNING: TO AVOID PERSONAL INJURY, ALWAYS
TURN MACHINE OFF, MAKE SURE ALL MOVING
PARTS COME TO A COMPLETE STOP.
DISCONNECT SPARK PLUG WIRE
BEFORE SERVICING UNIT.
RECONNECT SPARK PLUG WIRE, AND ALL
GUARDS BEFORE STARTING ENGINE.
WHEN POWER WASHING, DO NOT SPRAY
DIRECTLY ON THE BLADE CLUTCH.
Note: Blade, and drive belts are normal wear items. These should be inspected on a regular basis and replaced if worn.
Tip: To prevent wheels from seizing to axles remove them once per season and coat the axles with anti-seize compund. This should be done more often if using a pressure washer to clean the unit regularly.
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.
6.Replace the blade using all fasteners in the exact order they were removed. Torque blade screw to 60 ft-lbs. NOTE: Before installing the fasteners inspect them for wear and replace as necessary.
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 replacement. Billy Goat uses only premium quality, kevlar corded and coated belts in your unit. Substitute belts do not meet the design and performance require- ments 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).
8.Tighten four screws(103) to secure belt guides(149 & 150) in place. Note: With clutch levers engaged, be sure belt guides do not touch belts after installation.
9.Reconnect spark plug wire.
WHEEL DRIVE CLUTCH ADJUSTMENT
As the belt wears, adjustments may be required to maintain proper control cable tension, and clutch engagement. If the belt begins slipping or squealing during normal operation it may require an adjustment to increase the clutch cable (item 18) tension. A properly adjusted wheel drive clutch should require a minimum of 3 lbs. of force to completely depress the end of the clutch lever. Clutch cable tension adjustment is located at the back of the engine base. To increase tension adjust the cable so that more of the adjusting barrell is exposed on the outside of the machine. To decrease tension adjust the barrell in the opposite direction. When replacing a belt be sure to check that it is properly tensioned.
BLADE 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.Remove the two screws (103) and washers (141) holding the engine base door (7), and remove the door.
4.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.
5.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.
