These tools repair and maintain a vehicle's clutch. The clutch transmits engine power to the gear box and allows the transmission to be interrupted while a gear is selected. The clutch adjusting tool locks onto the bearing at the top of the clutch and holds the clutch in place, maintaining alignment while repairs are made. The Spicer clutch adjustable wrench aligns Spicer angle-spring and multiple-lever clutches. A spring compressor applies pressure to the clutch drum's retaining washer to compress piston return springs. The clutch wear installer attaches the rivets on the clutch wear plate.
