How to install door hinge pins.
Then install the lower pin into the top bushing moving and adjusting the door as you go to allow the pins to slide in somewhat freely.
Hold the door in place using blocks under the bottom to support it if necessary.
Force the pin up from the door hinge.
Insert the new brass cups into the hinge and then apply plenty of grease inside.
Connect the door to the jamb.
Continue to tap it up gradually increasing the force until the pin is finally lodged upwards.
Insert the hinge pin into the hole in the stopper assembly from above so that the shank of the pin extends below the assembly.
Taking a hammer and your nail punch gently ram the pin upwards.
This leaves the stopper assembly.
This will allow you to press the pin in that last little bit getting it seated fully into the hinge.
The pins have a serration under the head and this holds the pin tightly in the hinge.
Put the flat end of the nail against the pin and tap it up with the hammer.
With most doors this process does not go smoothly.
Once the pins are out knock the brass cups out of the hinge and clean inside the bore.
Knock the pin back into the hole using a solid base to rest on if the pin is slightly longer allow for the difference to let the bolt seat fully home.
Line up the two hinge plates so that the ones on the door match the ones in the jamb.
To seat the serration into the hinge just get out your socket again and place it over the point of the pin.
