What it is

The Baxi 7740179 is a two-piece spanner kit supplied for work on Baxi gas boilers, containing one small spanner and one large spanner. It is a service tool rather than a combustion or hydraulic component, used to remove and refit specific fixings during maintenance and repair. The kit is listed against the Baxi 836 Combi and the wider Baxi 818 System family.

Signs this part needs replacing

  • Spanner jaws rounded or worn, slipping on the fixing instead of gripping it
  • Corrosion or pitting across the tool surface
  • One or both spanners missing from the kit
  • Bent, cracked or deformed handle
