Worked as expected.
All the parts arrived within a week, they all fit and the nailer is shooting nails. The repair is easy to do and way cheaper than buying a new framing nailer.

Common Sense that's all. Open the head by removing the four allen screws, take out bad components, put new components in, look for broken pieces in cylinder. Replace the head and tight the four allen bolts. Oil and test.

Nothing to this repair. Remove the top cover of the nail gun. You will then see the damaged parts. Remove them & make sure there is no debris from the broken parts that are left in the gun. Lube the new parts and install them in the gun, then install the top cap. Start nailing again.
