17.1BLADE REMOVAL / SHARPENING
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).
