The Wacker Neuson is a genuine OEM Exhaust Manifold designed for a range of Wacker Neuson equipment including PTS4V series centrifugal trash pumps, GPS8500 and GPS9700 portable generators, GS8.5V and GS9.7V generators, and the RD880V tandem roller. As a direct factory replacement, part is manufactured to the exact specifications of the original component it replaces. This Exhaust Manifold installs directly in place of the worn or damaged factory unit, restoring proper exhaust flow and engine efficiency across all compatible models. Confirm your model number before ordering to ensure correct fitment.
Key Features
- Genuine OEM Construction — Cast to original factory tolerances, ensuring correct port alignment, wall thickness, and thermal resistance for sustained high-temperature exhaust duty.
- Direct-Fit Replacement — Bolt pattern and port dimensions match the original mounting points on PTS4V, GPS9700, GPS8500, GS8.5V, GS9.7V, and RD880V machines, so installation follows the standard service procedure.
- Broad Model Coverage — A single part number spans PTS4V centrifugal trash pumps, GPS8500 and GPS9700 portable generators, GS8.5V and GS9.7V generator variants, and the RD880V double drum vibratory roller.
- Restores Full Exhaust Scavenging — A cracked or warped manifold causes back-pressure buildup, power loss, and rough running; replacing it with 5000079603 restores the correct exhaust gas flow path and engine output.
- Exhaust Integrity and Operator Safety — A failed manifold can direct hot exhaust gases toward fuel lines, wiring, or the operator zone. Using the correct OEM replacement maintains the designed heat shielding and gas routing.
The exhaust manifold collects spent combustion gases from the engine's cylinder head and channels them into the exhaust outlet and muffler system. It must withstand extreme heat cycling without warping or cracking — if it fails, exhaust leaks can rob the engine of power, increase operating temperatures, and expose nearby components to damaging heat. On equipment like trash pumps, generators, and rollers that often run for extended periods under load, a properly sealed manifold is critical to maintaining consistent engine performance and protecting surrounding components from heat damage.
