🔌 Function

Bolts to the exhaust connection and provides the machined, sealed joint face the next section mates against.

⚠️ Common Signs of Failure

• Exhaust leak blowing at the flange joint
• Soot fanning out from between the faces
• Sealing face pitted, scaled or burnt
• Flange warped or bolt holes cracked
• Studs corroded or seized so the joint cannot be pulled up evenly

🛠️ Service Notes

• Flange 820915 is the Åkerman version and only 208 grams separates the two, so weight is no guide - order by engine designation
• Number 821113 is also listed as superseded by exhaust hose 820900, so confirm which item the old number came off
• Skim or replace a warped face and always fit a new gasket
