Vg1246010005 Sinotruk Howo Engine Spare Parts Front Crankshaft Oil Sea

Front Crankshaft Oil Seal Compatible With: Sinotruk Howo Trucks (Various Models – Specify engine family/model year for best accuracy, e.g., WD615 series) Part Number: VG1246010005

Function & Importance: This VG1246010005 Front Crankshaft Oil Seal is a critical engine sealing component designed specifically for Sinotruk Howo diesel engines. Its primary function is to create a high-pressure, leak-proof barrier at the front end of the engine crankshaft, where it exits the engine block.

Seals Engine Oil: Prevents vital engine lubricating oil from leaking out of the front of the engine block.
Excludes Contaminants: Acts as a barrier against dirt, dust, water, and other external contaminants from entering the engine’s internal bearings and oil system.
Protects Crankshaft & Bearings: By maintaining proper oil levels and cleanliness within the engine, it safeguards the crankshaft main bearings and other critical rotating components from premature wear, scoring, and failure.
Maintains Oil Pressure: A secure seal is essential for maintaining correct engine oil pressure.

Failure Consequences: A worn, damaged, or failed front crankshaft oil seal will lead to:

Visible Oil Leaks: Oil dripping from the front of the engine, often around the harmonic balancer/pulley area.
Low Oil Level: Resulting in inadequate lubrication, potentially causing severe engine damage (seized bearings, scored crankshaft).
Contamination: Allowing dirt/water ingress accelerates internal engine wear.
Oil Pressure Loss: Critical loss of lubrication pressure.
Potential for Major Engine Failure: If left unaddressed, leaking oil can lead to catastrophic engine damage requiring expensive repairs or replacement.
Key Features (Typical):

Precision Fit: Engineered to exact Sinotruk Howo specifications for optimal sealing performance.
Durable Materials: Constructed from high-quality materials (typically nitrile rubber or fluoroelastomer bonded to a steel case) resistant to heat, pressure, and engine oil.
Lip Seal Design: Features a specialized sealing lip that maintains constant contact with the crankshaft surface.
Spring Loaded: Often includes a garter spring to ensure consistent lip pressure against the crankshaft.
Direct Replacement: OEM-equivalent part designed for straightforward installation.
