How to change a group head gasket
Gaskets Preventative Maintenance
Prior to completing this preventative maintenance task, it is important to know what type of screen your machine uses. Machines using the E61 type group do not have a screw that holds the screen in place. The screen on this type of group is held in place by the gasket. Lever machines also do not use a screw. These are held in place by spring-type clips attached to the side of the screen.
