Product Overview
3406906X Rocker Lever Cover Spacer (SPACER,ROCKER LEVER COVER) is a large-size high-rigidity mounting spacer specially designed for Cummins series diesel engine rocker lever cover assemblies. It is installed between the engine rocker cover and cylinder head, mainly used for gap calibration, height adjustment, vibration buffering and sealing auxiliary support. This spacer effectively solves common engine faults such as uneven installation gaps, rocker cover deformation, oil leakage, vibration loosening and abnormal running noise caused by aging, deformed or fatigued old spacers. It optimizes the assembly tightness of the rocker lever cover, maintains stable internal pressure of the valve chamber, and ensures long-term stable operation of the engine valve train system.
Core Product Advantages
1. High-Rigidity Integrated Structure: Adopts high-density industrial material integral forming process, with strong compression resistance and load-bearing capacity. It does not deform, sink or crack under long-term bolt preload and engine high-frequency vibration.
2. Accurate Gap Calibration Performance: Strict dimensional tolerance control ensures precise assembly gap between rocker cover and cylinder head, effectively avoids installation deviation, eliminates partial extrusion and poor sealing, and improves overall assembly accuracy.
3. Excellent Vibration Isolation & Noise Reduction: Optimized structural toughness can buffer engine mechanical vibration and operating impact, reduce vibration transmission of rocker cover assembly, lower resonance noise and prevent bolt loosening caused by jitter.
4. High & Low Temperature Stability: Stable physical performance in extreme working environment of -40℃ to +135℃. No thermal softening or deformation in high-temperature engine compartment, no brittle failure in low-temperature harsh conditions.
5. Oil & Corrosion Resistance: Professional surface passivation treatment resists long-term erosion of engine oil, high-temperature oil vapor and dust oxidation, avoiding corrosion and aging failure, greatly extending service life.
6. Large Size Standard Matching: Standard overall dimension 95.7cm*36.4cm*12.9cm and 7.728KG stable weight design perfectly fit Cummins engine rocker cover assembly structure, supporting accurate direct replacement without secondary trimming.
7. Strict Factory Quality Inspection: Finished spacers pass flatness detection, compression fatigue test and vibration aging test, with stable batch quality for engine overhaul maintenance and fleet bulk procurement.
