1555619 Flywheel Rear Cover Housing Gasket — Cat 3406

This flywheel rear cover housing gasket is essential for sealing the connection between the engine block and the flywheel housing, preventing oil and debris ingress. Manufactured to meet strict OEM quality standards, it provides a durable seal superior to a degraded or torn gasket. Operators may observe oil leaks originating from the rear of the engine or transmission bell housing if this gasket fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The most common indication of a failed flywheel rear cover housing gasket is oil leakage from the area where the engine block meets the transmission bell housing. If this leak is ignored, it can lead to significant oil loss and potential damage to the clutch or torque converter. Continued operation with a leaking gasket risks contamination of drivetrain components.

Installation Tip

Ensure the sealing surfaces on both the engine block and the flywheel housing are perfectly clean and free of old gasket material before installation. Avoid using excessive sealant unless specifically recommended, as it can interfere with proper gasket seating.

Service Note

Inspect the rear crankshaft seal for leaks and wear when replacing the flywheel rear cover housing gasket.
