Product Detail

Product Description: SEAL RING 4043000256 for SDLG 956L Wheel Loader

The Seal Ring 4043000256 is a genuine OEM sealing component for the SDLG 956L wheel loader and other compatible LG series models within the 5-ton class wheel loader family, including the LG956L, L956F, LG953, LG958, and LG968. This seal ring is a precision elastomeric sealing element designed to prevent hydraulic fluid, engine oil, coolant, fuel, or other operating media from leaking out of a joint while simultaneously preventing the ingress of dust, water, and abrasive contaminants into the hydraulic and drivetrain systems. It is most likely used as a static seal within the steering rack system of the wheel loader, sealing the interface between the steering rack and the pinion housing or between the rack ends and the tie rod ball joints.
