The Wacker Neuson Lock Washer A10 is a genuine OEM lock washer designed for the LTN4Y, LTN5Yp, LTN5Ypk, RD7H, RD7Yeh, RD7Heh, RD7Af, and RD10Yehf series machines. Sourced directly from Wacker Neuson, this part carries the same exacting standards as the component installed on the assembly line, ensuring a consistent, dependable result every time it is installed. With confirmed fitment across a broad range of light tower and soil compactor models, part number is a straightforward, no-guesswork replacement for worn or missing hardware.
Key Features
- Genuine OEM Hardness and Temper — Manufactured to Wacker Neuson's specified metallurgical grade, so the washer delivers the correct clamping force and spring tension without deforming under torque.
- Direct Hardware Replacement — Matches the A10 bore diameter and tooth profile of the original, allowing the fastener assembly to be completed without re-drilling, shimming, or substitution.
- Broad Series Fitment — Confirmed for LTN4Y and LTN5Y light tower series, as well as RD7H, RD7Yeh, RD7Heh, RD7Af, and RD10Yehf soil compactor series, covering a wide range of Wacker Neuson equipment in a single part number.
- Prevents Fastener Loosening — The locking geometry bites into the mating surface under vibration, keeping critical bolted connections secure during sustained machine operation where vibration loads are high.
- Genuine Part Traceability — Supplied as an authentic Wacker Neuson component under part number 5100006629, giving you full confidence that the specification matches the original engineering drawing.
A lock washer is a small but essential piece of hardware placed beneath a bolt or nut to resist loosening caused by vibration and dynamic loading. Its serrated or split profile bites into both the fastener face and the mounting surface, creating mechanical resistance that prevents the fastener from backing out during operation. When a lock washer is missing, worn flat, or substituted with an incorrect size, the joint can work loose over time, leading to misalignment, component damage, or fastener failure at the worst possible moment.
