- Reinstall the crankshaft sealing flange over the new gasket.
- Tighten the flange bolts in the sequence and to the torque values specified in your engine's service manual.
- Reassemble any other components that were removed for access.
- Once assembly is complete, reconnect the battery, start the engine, and carefully inspect for any oil leaks around the flange area.
Troubleshooting & FAQ
How do I know if this gasket will fit my engine?
This gasket is designed for Volvo Penta B-series engines like the B200 and B230. To ensure compatibility, please check your engine model and original part number against our compatibility table. This part is a direct cross-reference for Volvo Penta parts 1378493 and 1276817.
What are the signs of a failing crankshaft flange gasket?
The most common symptom is an oil leak from the rear of the engine, near where the engine connects to the transmission or bell housing. You may notice oil drips on the ground or a consistently low engine oil level.
Is sealant required for installation?
This paper/composite gasket is typically designed to be installed dry. However, always consult your engine's official service manual, as a very thin application of a specific sealant may be recommended in some cases to ensure a perfect seal.
