Product Detail

Product Description: WELD PIN 4043000728 for SDLG 956L Wheel Loader

The Weld Pin 4043000728, officially designated as LGB301-85×115×210/2G-40Cr under the Chinese national LGB301 standard, is a genuine OEM component for the SDLG 956L wheel loader and other compatible LG series models within the 5‑ton class wheel loader family, including the L956F, LG956L, LG953, LG958, LG968, and LG936L wheel loaders. This weld pin is a critical structural fastener within the loader’s front working equipment linkage, serving as a fixed pivot axis for connecting components such as the bucket linkage, lift arm assembly, rocker arm mechanism, or working device accessories. As a weld‑on pin, it is designed to be permanently welded into the mounting lug, providing a stationary bearing journal around which the corresponding component rotates, with a replaceable bushing (such as LGB302 series bushing) sliding over the pin‘s 85 mm diameter journal.
