Details

Rancilio Z-9/Z-11 Group Valve Spring

Group valve spring used in Rancilio's earliest lever groups, and still in service today in the Classe 6 and 7 Leva group heads.

SPECIFICATIONS

  • Rancilio OEM part #: 39110065

COMPATIBILITY

  • Fits: Rancilio S-10, Z-9, Z-11 lever groups (including the old Z-9/Z-11 "automatic" group), and Classe 6 & 7 Leva group heads
  • Replaces: Rancilio 39110065

INSTALLATION

Basic hand tools; straightforward DIY replacement for anyone comfortable disassembling the group valve.

PRO TIPS

  • A fatigued valve spring is a common cause of weeping or sluggish valve action between shots on Z-9/Z-11 and Classe Leva groups — if you're seeing water dripping from the group when idle, this spring is worth checking before you assume the valve seat itself has failed.
