C3685173 X15 Multi-Layer Composite Sealing Oil Seal for Cummind Excavator Engine Parts

Construction machinery For 3685173 oil seal Cummind X15 Excavator Engine Parts

Specification

Description

This product is a special construction machinery excavator engine oil seal with part number C3685173, compatible with X15 series engines. It is a core sealing component for engine crankshaft/main shaft positions. Adopting an integrated composite sealing structure, it is manufactured in strict accordance with original dimensional tolerance standards, perfectly matches the installation cavity and shaft diameter, can fully replace original old parts, and is widely used in power assembly systems of various heavy-duty excavators and construction machinery.

Advantage

Precise original-spec size: 1:1 replicates original specification parameters, with high installation fit, no secondary grinding modification required, achieving zero-clearance matching after assembly
Multi-layer composite sealing structure: Combined with metal framework & high-performance elastic sealant, it features strong rigid support and excellent extrusion & deformation resistance
High temperature resistance & anti-aging performance: Adapted to complex engine working conditions, it is resistant to hardening, cracking and permanent deformation under long-term high temperature, oil pollution and vibration environments
Long-lasting anti-leakage performance: Optimized lip sealing design, greatly reduces risks of engine oil leakage and oil-gas leakage, and extends engine maintenance cycle
Heavy-duty construction machinery reinforced material: Specially optimized for high-load working conditions of heavy excavators, with a service life far exceeding ordinary civil oil seals

Performance

Sealing stability: The lip fits tightly under dynamic rotating working conditions, and provides reliable sealing under static high-pressure oil chamber environment, effectively blocking engine oil leakage channels
Medium resistance performance: Resistant to engine lubricating oil, diesel oil and oil-gas mixed medium, without swelling, corrosion or softening failure after long-term immersion
Temperature adaptability: Works stably in a wide temperature range of -40℃~180℃, fully covering all working temperatures of engine cold start and high-load full-load operation
Mechanical anti-fatigue performance: Resists continuous engine vibration and shaft eccentricity swing, resistant to wear and lip collapse failure after long-term reciprocating operation
Installation durability performance: Compliant with original disassembly & assembly specifications, with long service life after single installation, greatly reducing downtime maintenance frequency of construction machinery
