At this time, the center line of the U-shaped groove coincides with the center line of the bearing shell, and the center line of the positioning screw coincides with the center line of the rocker shaft hole of the bearing shell. The lip seal ring is horizontally placed at the location to be installed in the rocker shaft hole of the bearing shell, and the pressure cylinder is placed Insert it onto the lip seal to be installed; screw the rotary press-fitting module into the positioning screw. At this time, the rotary press-fitting module, the pressing cylinder and the lip seal to be installed are all on the same axis. Tighten the rotary press-fitting module at a uniform speed to make the pressing cylinder move downward, and press the lip seal into the rocker arm shaft hole of the bearing housing at a uniform speed and vertically, and finally press it into place; after the pressing is completed, unscrew the rotary press-fitting module, remove the pressing cylinder and the bearing housing, so as to maintain a uniform speed, pressure and installation verticality, prevent the oil seal from deforming and causing sealing failure.
