Original Wolf Garten part 0017103 — a slim flat washer used on the WE 430 spreader (Wolf‑Garten model 5450000 / WE 430 Perfect).

This genuine Wolf Garten washer is specified as 18.5 × 28 × 1 mm (inner Ø 18.5 mm, outer Ø 28 mm, thickness 1 mm) and is listed as ST33ZN (zinc‑plated steel), so it slips over the axle / pin to secure the wheel/drive link components without adding play.

The part appears in the WE 430 parts diagram (pos. 10) and is fitted twice on the assembly, so replace both if one is corroded, bent, or worn to restore correct alignment and smooth operation.

Perfect for anyone repairing a WE 430 spreader and looking specifically for original Wolf Garten spare parts to restore factory fit and function — a simple, inexpensive replacement that re‑establishes correct spacing on the axle and prevents rapid wear of nearby components.
