Sourced directly from Multiquip, this exhaust manifold meets the exact specifications of the original part it replaces, ensuring a correct, trouble-free installation. Confirm your model and engine designation against part number 1G86612310 before ordering to ensure accurate fitment with your D1403-powered unit.
Key Features
- Genuine OEM Casting Integrity — Manufactured to the same material grade and port geometry as the original, maintaining proper exhaust gas flow and thermal performance specific to the D1403 engine.
- Direct-Mount Replacement — Matches the original bolt pattern and flange dimensions of the D1403, allowing straightforward removal and reinstallation without modification to mounting hardware.
- D1403 Engine Fitment — Engineered specifically for Multiquip equipment running the D1403 engine; verify your engine model code before purchase to confirm compatibility.
- Sustained Exhaust Efficiency — A properly sealed manifold keeps exhaust gases channeled away from the engine bay, protecting surrounding components from heat damage and maintaining correct back pressure for optimal engine output.
- Exhaust Integrity and Operator Safety — A cracked or failed manifold can allow hot exhaust gases to escape into the engine compartment, creating a burn and fire hazard; replacing a damaged manifold promptly with a genuine OEM part restores proper containment.
The exhaust manifold collects burned gases from each cylinder of the engine and directs them into a single outlet, routing exhaust safely away from the machine. On a D1403 engine, maintaining a tight, crack-free manifold is critical — any leak allows extremely hot gases to escape under the hood, accelerating wear on nearby hoses, wiring, and components while also creating a safety hazard for the operator. A warped or cracked manifold can also disrupt back pressure, leading to reduced engine efficiency and rough running. Replacing a worn manifold with the correct OEM unit like the Multiquip 1G86612310 restores proper sealing and exhaust flow.
