The new rivets came in from the UK yesterday and got them installed.  My Arrow rivet tool kind of sucks ... I really need to get a better one and one that has more fittings for smaller rivets too.

The install for backplate of the cage to the boiler needed a bit more than installing the rivets.  This is because the roller had a very hard hit from the back, which pushed in the backplate into the boiler - so it has a pretty bad indention.  Perhaps the rivet would have seal it okay but I didn't want to try a 2nd time if it didn't.
  • Permatex 90 Minute High-Temp #34628 on the boiler around the rivet holes.
  • Red Fiber washer with Permatex on both sides for both holes.
  • A bit of Permatex on the Rivet itself before inserting it into the backplate.
  • After pushing the rivets into the backplate I put on a 3mm x 1mm O-Ring - this was to make up the slop between the inner washer and outer rivet.
  • I also put some Permatex on the boilier/backplate just under the drain hole to help keep water from getting between them.
After waiting 90 minutes did a test run, perfectly sealed and runs great - job completed! YAY!
