856580 Crankshaft Seal | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta crankshaft seal from the Engine group, weighing 0.046 kg and listed for three applications across the BB and SHIELD groups - the same three applications carried by Engine gaskets 856608 and 856626 in this run. It is within one gram of gasket 856608, so weight identifies nothing; order by part number.

🚤 Compatibility

Typically suits:

• Volvo Penta 740A
• Volvo Penta BB740A
• Volvo Penta Shield for 740A

• Engine Family: BB, S

⚙️ Key Features

• Engine group crankshaft seal
• 0.046 kg
• Three applications across BB and SHIELD
• Shares its fitment with gaskets 856608 and 856626

🔌 Function

Seals against the rotating crankshaft to keep engine oil in and water and dirt out at the shaft exit.

⚠️ Common Signs of Failure

• Oil drip or a wet film below the crankshaft nose or flywheel end
• Oil thrown in a fan pattern around the housing
• Oil level dropping between services
• Seal lip found hardened, split or turned back on removal
• A polished groove worn into the shaft where the lip rode

🛠️ Service Notes

• Check the shaft for a wear groove before fitting - a new seal into an old groove leaks again straight away
• Gaskets 856608 and 856626 share the same three applications and are worth having to hand when the cover comes off
• Fit the seal square and to the correct depth; a cocked seal will weep from new

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
