1 Take out the elastic retaining ring for the hole with needle-nose pliers, and tap the threaded head of the steering shaft lightly and evenly with a copper hammer until the outer ring of the bearing comes out of the inner hole of the support, and pull out the steering shaft with bearing assembly from the lower end of the support .Note that when the copper hammer hits the threaded head of the steering shaft, measures should be taken to protect the thread to prevent the thread from deforming.

　　2 Check whether the sliding fork assembly and the universal joint fork assembly rotate flexibly, whether they are corroded or pinched. If there is one of the defects, disassemble the cross shaft with grease nipple assembly.

　　3 The bearing on the other axis is also operated according to the direction and procedure shown in the figure.

　　4Remove the bearing as shown in the figure.Note that the parts are not damaged and rotate flexibly after inspection, so there is no need to disassemble and inspect the bearing.

　　5 Clean the parts with clean gasoline and kerosene.Be careful not to use gasoline to clean the rubber oil seals, and do not use steam or alkaline cleaning fluid to clean the bearings.After cleaning, blow the parts with dry, clean compressed air.
