Reamer Care & Reaming Instructions

Sonnax offers a variety of custom reaming tools and fixtures to simplify the repair of worn-out valve body, pump and transmission case bores.

The instructions below provide general, step-by-step directions for reaming. Since all tooling is designed to work with specific Sonnax parts, ALWAYS refer to those unique part instructions – not these general instructions – before beginning repairs. Some tool kits must be used with the Sonnax VB-FIX, a self-aligning fixture that provides an external rigid pilot bore for the reamer and guide pin. Sonnax part numbers for these tools begin with "F-" to distinguish them from standalone tools.
