Eliminate shaft play and maintain perfect gear train alignment with our Premium 11431708 (4804414) Engine Shaft Collars/Spacers for VOLVO EC210B, EC240B, and EC300D excavators. Get direct factory pricing, bulk B2B discounts, and fast global air express shipping from China's leading powertrain components supplier today!
Maintain Precision Timing and Alignment. Worn spacer causes shaft displacement, gear abrasion and timing deviation. This hardened positioning ring bears axial thrust steadily, keeps gear train accurate and reduces abnormal wear for Volvo D4/D6/D7 diesel engines.
Chrome-Moly Hardened Alloy High strength anti-fatigue, resist extrusion deformation and surface scratch damage.
Mirror Polished Thrust Surface Low friction heat generation, maintain stable axial alignment under peak torque.
Strict Dimension Tolerance Perfect shaft fitting, avoid rotation offset and concentric deviation.
Oil Corrosion Resistance Stable performance against high temperature lubricating oil and soot dispersant erosion.

Precision shaft collar is essential overhaul part. Reused worn parts easily lead to gear noise and seal failure. Engine repair workshops and spare parts wholesalers suggest stocking genuine 11431708 collars. Match with crankshaft seal, pump gaskets and intake gaskets to form complete overhaul assembly.
Sharp gear whining noise from timing cover, abnormal sound varies with rotating speed change
New oil seal leaks oil in short time, shaft swing displacement causes sealing failure
Collar surface grooved and worn, axial clearance over standard affecting timing precision
All models for compatibility reference only. Qualified positioning collar stabilizes shaft and gear position, guarantees timing accuracy, effectively prolongs overall engine service life.
