The Multiquip 42691 Exhaust Header is a genuine OEM component designed for HTX6H and STX6H Hatz-powered ride-on power trowels. As a direct Multiquip OEM part, the 42691 is manufactured to the same specification as the original, ensuring a correct, hassle-free installation on your machine. This part is sourced directly through authorized Multiquip distribution channels, so you can be confident you're receiving the exact component your trowel was built with. Compatible models include the HTX6H and STX6H series ride-on trowels.
Key Features
- Genuine OEM Construction: — Manufactured to the original Multiquip exhaust specification, including correct port geometry, flange dimensions, and heat-grade materials required for a Hatz diesel exhaust system.
- Direct Bolt-On Replacement: — Engineered to align precisely with the Hatz engine exhaust port and the trowel's existing mounting points, so installation requires no fabrication or adapter hardware.
- Confirmed Fitment: — Verified compatible with HTX6H and STX6H hydrostatic ride-on trowels equipped with the Hatz diesel engine.
- Sustained Engine Performance: — A properly sealed exhaust header maintains correct back pressure and keeps exhaust gases routed safely away from the operator and mechanical components, allowing the engine to run at full rated output.
- Operator Safety: — A cracked or failed exhaust header can direct hot gases toward fuel lines, hydraulic hoses, and the operator platform. Replacing a damaged header promptly is a critical safety measure on ride-on trowel equipment.
The exhaust header is the first section of the exhaust system, connecting directly to the engine's exhaust ports and channeling combustion gases away from the engine and toward the muffler or exhaust outlet. It is exposed to extreme heat cycling every time the machine runs, which over time can cause cracking, warping, or gasket failure at the mating surfaces. When the exhaust header fails, exhaust leaks reduce engine efficiency, produce excessive noise, and create a burn or fire hazard near surrounding components. Replacing a worn or damaged header restores proper exhaust flow and keeps the engine operating as designed.
