856434 Spacer Flange | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta spacer flange from the Inlet and Exhaust System group, weighing 6.595 kg and listed for three applications in the BB range - the same three applications carried by spacer flange 856433 at 4.055 kg. No dimension is published for either, so the difference in mass cannot be taken as a difference in thickness. Order by part number against the installation.

• Spacer flange 856433 shares the same three applications - order by part number rather than by weight
• At 6.595 kg it is an awkward one-handed lift; support it while the fasteners are started
