EXHAUST MANIFOLD FOR FORD, PART NO. D5NN9431A

Exhaust Manifold for Ford 10, 30, 700, and TW Series Tractors

The Ford exhaust manifold, part numbers D5NN9431A and 83903562, is a replacement part designed for several Ford tractor models. It is mounted on the engine to collect exhaust gases and direct them into the exhaust system. This part number is intended for users seeking a clear match with their specific Ford model and their original part.

Role of the Manifold on the Engine

The exhaust manifold is part of the exhaust system. Its general function is to channel exhaust gases from the engine before they pass through the rest of the system. When this part is cracked, warped, or damaged along its sealing surfaces, leaks may occur, accompanied by abnormal noise around the engine.

Replacing a worn manifold primarily restores proper exhaust flow and ensures a clean connection to the exhaust system. On a work vehicle, this part must be identified precisely to avoid installation discrepancies between similar variants.

Useful part numbers and documented applications

This part is associated with part numbers D5NN9431A and 83903562. It is documented for Ford tractors in the 10, 30, 700, and TW series. Among the models covered are the 7810, 7910, 8210, 8530, 8630, 8730, 8830, 8700, 9700, as well as TW10, TW15, TW20, TW25, TW30, TW35, and TW5.

If you are replacing the original part installed on your tractor, matching the part number remains the most reliable method, supplemented by verifying the exact model of the machine.

How to Choose the Correct Part Number

To select the correct manifold, start by checking the full model designation of the Ford tractor in question. Similar series may include several versions, which is why it’s important to confirm both the model and the part number listed on the old part, if it is still legible.

It’s also helpful to examine the condition of the existing assembly: look for cracks, signs of leakage around the cylinder head, deformation of the mounting surfaces, or exhaust noise coming from near the engine. These signs often indicate that the manifold needs to be replaced rather than simply retightened.

Points to Check During Replacement

Before reassembly, check the condition of the gaskets and fasteners associated with the manifold. A clean mounting surface and components in good condition facilitate proper reinstallation. If your tractor is one of the Ford models listed below and the part numbers match, you have a good starting point for identifying the correct part.

If you’re unsure which version to use, refer to part number D5NN9431A or 83903562 and the exact tractor model to verify compatibility before ordering.

FAQ — Frequently Asked Questions

What is the purpose of this exhaust manifold on a Ford tractor?

This exhaust manifold collects the exhaust gases from the engine and directs them into the exhaust system. On a tractor, a cracked or warped part can cause noise, an exhaust leak near the engine, or rough running when the engine is warm.

Does part number D5NN9431A correspond to 83903562?

Yes, this part is identified by both part numbers D5NN9431A and 83903562. To select the correct part, check the part number on your old part if it is legible, then confirm compatibility with the exact model of your Ford tractor.

Is this manifold compatible with the Ford 7810, 8730, or TW20?

Yes, these models are among the documented applications for this part number. The manifold is designed for Ford tractors in the 10, 30, 700, and TW series, including the 7810, 8730, and TW20. Always verify the exact model designation before replacement.

What signs indicate that an exhaust manifold needs to be replaced?

Replacement is recommended in the event of cracks, exhaust leaks, abnormal noise near the engine, or damage to the manifold. If the old part is deformed or not sealing properly, it is also advisable to check the condition of the gasket and fasteners during reinstallation.
