The Wacker Neuson 5000406644 Muffler is a genuine OEM component designed for AP, BPS, and VP series vibratory plate compactors. As a direct OEM replacement, it is manufactured to the same standards as the original part installed at the factory, ensuring a proper fit with no guesswork on installation. This muffler is confirmed for a wide range of models including the AP 1135A, AP 1550A, BPS1030A, BPS1135A, BPS1340A, BPS1550A, BPS2050A, VP1135A US, and VP 1135AW, among others. Sourcing the correct OEM muffler keeps your compactor operating at the right exhaust back-pressure and noise level from the first start.
Key Features
- Genuine OEM Exhaust Specification — Engineered to match the original exhaust flow and back-pressure requirements of the engine, maintaining proper combustion efficiency on your plate compactor.
- Broad AP, BPS, and VP Series Coverage — Confirmed fitment across the AP 1135A, AP 1550A, BPS1030A, BPS1030Aw, BPS1135A, BPS1340A, BPS1340Aws, BPS1550A, BPS1550Aws, BPS2050A, BPS2050Aw, VP1135A US, and VP 1135AW models.
- Direct Bolt-On Replacement — Matches the original mounting configuration, so installation is straightforward using standard hand tools with no fabrication or adapter fittings needed.
- Correct Sound Attenuation — Restores the designed noise suppression level of your compactor, keeping exhaust sound within the expected operating range for worksite compliance.
- Exhaust Safety Compliance — A properly functioning muffler directs hot exhaust gases away from the operator and nearby workers; a cracked or failed muffler creates a genuine burn and inhalation hazard that this OEM replacement resolves.
The muffler collects exhaust gases from the engine's cylinder head and channels them through a baffled chamber that reduces both temperature and noise before venting to the atmosphere. On a vibratory plate compactor, the muffler is subject to constant vibration and heat cycling, which over time can cause cracks, corrosion, or mounting failures. A damaged muffler raises exhaust noise, can direct hot gases toward fuel lines or the operator, and may alter engine back-pressure enough to affect power output — making timely replacement an important part of routine compactor maintenance.
