Spider Assembly Description
The YNF16413 spider ass’y, equivalent to Komatsu part 56B-20-11910, is a vital universal joint component in the driveline of WA500-6 wheel loaders. It connects propeller shaft ends and enables the transmission of rotational torque between misaligned shafts. Constructed from heat-treated alloy steel, this spider is engineered to withstand the harsh loads, vibrhttp://spinder ass’yations, and torsion found in quarry, mining, and construction environments. The component includes precision-fitted needle bearings and greasing points for extended wear life. A critical spare for B2B parts suppliers, fleet managers, and equipment repair providers working on Komatsu loaders.
