a: fixing the clutch slave cylinder on the clutch, connecting an oil inlet with an oil inlet of the clutch master cylinder through a connecting oil pipe, hermetically connecting an output end of an air inlet nozzle with an air inlet of the clutch master cylinder through an air joint and a connecting bolt, filtering the entering air by using a filter screen, fixedly connecting one end of a connecting head far away from a push rod with the clutch, fixedly connecting one end of a leather sheath with a groove, and installing the other end of the leather sheath in a gap between the push rod and the connecting head to complete the connection of the clutch slave cylinder;
b, after the step A is finished, a clutch is pedaled, oil enters an inner cavity of the pump through an oil inlet, the oil pushes a piston assembly to slide in the inner cavity of the pump, the wedge-shaped slice on the left side of a leakage-proof sleeve shovels the oil adhered to the inner surface of the inner cavity of the pump to reduce the corrosion of the oil adhered to the inner surface of the inner cavity of the pump to cause oil leakage, the leakage-proof sleeve and a lug fixed on the surfaces of the piston assembly and the slice can effectively reduce the impact of the oil on the piston assembly to further prevent the piston assembly from being damaged to cause oil leakage, if the piston assembly still leaks oil, the oil leakage passes through the piston assembly to enter a crack formed by the inner cavity of the pump and a fixing ring, the surface of the fixing;
and C, after the step B is finished, the connecting plate slides in the oil leakage groove under the driving of the fixing ring, oil at the bottom of the fixing ring is sucked into the oil leakage groove through the oil suction groove and the one-way valve, the one-way valve has the characteristic of one-way passing, and a user can feel resistance generated by the oil when stepping on the clutch again under the action of the one-way valve and the return spring, so that the oil leakage of the clutch slave cylinder can be found quickly, and the clutch can be replaced.
