The Hatz Crankcase O-Ring (OEM 03795800) is a replacement sealing component used within the crankcase assembly of compatible Hatz diesel engines. It provides a secure seal between mating engine components, helping prevent the escape of oil and maintain the integrity of the engine's internal sealing system.

Manufactured for use within the demanding environment of a diesel engine, the sealing ring is designed to withstand engine oil, vibration, temperature changes and repeated operating cycles. Replacing a worn, hardened or damaged seal helps prevent leaks and maintain reliable engine operation.

IMPORTANT INFORMATION

Sealing rings should be replaced whenever they show signs of hardening, cracking, flattening, deformation or deterioration. Reusing an old seal during crankcase maintenance can result in oil leakage and may compromise the sealing of the assembled components.

Before installation, ensure the sealing surfaces and retaining locations are clean and free from damage. Fit the replacement ring correctly without twisting, cutting or overstretching it, and ensure all associated components are correctly positioned before returning the engine to service.
