LPowners.org Tools for Grouphead Rebuild

Bruce Colglazier Pappas

Tools and supplies recommended to rebuild grouphead and steam wand - Gen3 Pro (Millennium Professional):

  1. 10 mm wrench (box preferred) to remove group head bolts and steam wand assembly [Amazon]
  2. Hook and pick set for removing gaskets [Amazon]
  3. Retaining ring pliers to replace piston shaft gasket [Amazon]
  4. Sleeve removal bar to remove Millennium Teflon sleeve (if you're replacing it) [Stefano]
  5. Adjustable socket wrench to turn the sleeve removal bar (#4 above) [Amazon] -or- this [Stefano]
  6. 1/8” drive pin punch to remove rolled steel pin from knob [Amazon]. A cut nail will also work.
  7. 14 mm wrench (box or socket preferred) to remove cap nut from threaded piston pin [Amazon]
  8. Food grade lubricant [Amazon] -or- this [Stefano]
  9. Detergent for soaking parts to remove coffee residue [Stefano]
  10. Descaler for fill tube and boiler [Amazon]

All these tools and supplies are not required, aside the retaining ring pliers and lubricant. But this is what I used and they made the job easier.
