step 3, translating the moving block (6) to the outside of the clutch, enabling the hole aligning pin (1) to leave the oil passing hole (28), and then turning the moving block (6) for 90 degrees clockwise relative to the fixed block (8);
step 4, grabbing the clutch assembly, and shaking the whole device until 2 shell positioning pins (3) are inserted into the transmission shell positioning holes (29); at the moment, the spline of the clutch is matched with the spline of the transmission shell in place, and the oil passing hole of the clutch assembly is coaxial with the oil passing hole of the transmission shell.
