The Wacker Neuson 5200020933 is a genuine OEM Starter Housing designed for the MS64A Vibratory Rammer and the APT4S and APT4T pump series, including cold weather and electric and surge brake configurations. As a direct OEM replacement, this part is produced to the same standards as the original component installed at the factory, ensuring correct fitment and function across all compatible machine variants. The 5200020933 covers a broad range of APT4T and APT4S configurations — including skid-mounted, surge brake, electric brake, and cold weather models — making it a versatile stocking part for fleets running multiple units. Verify your machine model number before ordering to confirm compatibility with your specific unit.
Key Features
- Genuine OEM Construction — Molded and dimensioned to the original housing specification, ensuring the recoil starter assembly seats and anchors correctly without adjustment.
- Direct-Mount Replacement — Matches the original bolt pattern and engagement geometry of the MS64A, APT4S, and APT4T series for a straightforward swap during service.
- Broad Fitment Coverage — Compatible with the MS64A Vibratory Rammer and multiple APT4S and APT4T pump variants, including cold weather, electric brake, and surge brake configurations.
- Protects Starter Mechanism Integrity — A cracked or broken housing exposes the recoil spring and pawl assembly to impact and debris, which can cause complete starter failure and prevent the engine from being pulled over.
- Wacker Neuson Part Number Verified — Listed under part number 5200020933; cross-reference this number against your machine's parts diagram before purchase to confirm correct application.
The starter housing is the structural shell that encloses and protects the recoil starter assembly — including the pull cord, rewind spring, and engagement pawls. It mounts directly to the engine shroud and keeps all starter components aligned so that each pull engages the flywheel cleanly and the cord retracts correctly after each start attempt. When the housing cracks, warps, or breaks — typically from impact or prolonged exposure to heat and vibration — the internal components lose their alignment, leading to difficult starting, cord jams, or a starter mechanism that fails to engage the engine at all. Replacing the housing promptly restores reliable engine starting and prevents secondary damage to the recoil assembly inside.
