The Wacker Neuson Starter Pulley is a genuine OEM starter pulley designed for the BS50-4As, BS60-4As, and BS70-4As series vibratory rammers. As a factory-sourced component, this part is manufactured to the same specifications as the original, ensuring a direct, trouble-free installation on your Wacker Neuson rammer. The covers a broad range of BS-series configurations including 280 mm and 11-inch shoe variants, making it the correct choice across the full BS50-4As, BS60-4As, and BS70-4As lineup. When a starter pulley wears or breaks, the engine simply won't pull-start — getting the right OEM part back on the machine keeps your crew moving.
Key Features
- OEM-Matched Recoil Engagement: — Manufactured to factory pulley geometry so the recoil rope seats and winds consistently, delivering smooth, repeatable pull-start action.
- Drop-In Installation: — Matches the original mounting interface on BS-series rammer engines, fitting without modification to the recoil starter housing.
- Broad BS-Series Coverage: — A single part number covers BS50-4As, BS60-4As, and BS70-4As models across multiple shoe configurations, including 280 mm and 11-inch variants.
- Restored Cold-Start Reliability: — A worn or cracked pulley causes rope slippage or complete pull-start failure; this genuine replacement restores full starting function immediately.
- Genuine Wacker Neuson OEM Part: — Sourced directly through the Wacker Neuson parts network, so you receive the same component that shipped with the machine from the factory.
The starter pulley is the grooved drum at the center of a recoil starter assembly that guides and winds the pull-start rope. When you pull the handle, the rope unwinds from the pulley and spins the engine flywheel to initiate combustion; a spring then retracts the rope as the pulley resets. Over time, the rope groove can wear, crack, or chip — especially on high-cycle compaction equipment like vibratory rammers — causing the rope to slip out of track, fray, or preventing the engine from cranking at all. Replacing a damaged starter pulley promptly restores reliable engine starting and prevents secondary damage to the recoil spring and housing.
