Split the lock nut and lock washer on the lock sleeve。
Insert the set sleeve into the shaft and place it in the installation position of the set seat bearing。
When the fixing sleeve is difficult to insert, the screwdriver can be inserted into the groove of the fixing sleeve to expand the groove to make it easy to insert。
Insert the seat bearing into the shaft and place it in the position。
Use the torque wrench to tighten the mounting bolt of the bearing seat according to the specified locking torque。
