What if glass sliding door can't push the kitchen?

The glass door can't be pushed because the roller at the lower end is worn and needs to be removed and replaced with a new roller. Need tools: art knife, screwdriver, two new rollers, vise. The specific operation is as follows:

1. Push the door to lift the glass upward, and then take it out obliquely.

2. Turn the screws on both sides of the lower end of the glass door with a screwdriver.

3. Then cut the glass glue along the lower end with a utility knife, and cut both sides.

4. Then use a vise to remove the underframe bit by bit.

5. Pour out the worn rollers in the bottom frame.

6. Install new rollers, always two * * *, then screw the screws in the same way and install them obliquely back to the glass door.
