A genuine, multi-layered steel (MLS) exhaust manifold gasket. It has been designed by JCB engineers to provide a perfect seal at the junction of the manifold and the cylinder head under the extreme pressures and temperatures found in DieselMax and EcoMax engines. It is a key element for maintaining full engine power and proper turbocharger operation.
Genuine JCB product – a guarantee of the highest quality, perfect fit, and 100% compatibility with your machine.
| Brand (Machine Type) | Model |
|---|---|
| JCB (Backhoe Loaders) | 3CX, 4CX (with DieselMax / EcoMax engines, manufactured after 2005) |
| JCB (Telehandlers) | Loadall (wide range of models with DieselMax / EcoMax engines) |
| JCB (Wheeled & Tracked Excavators) | JS130, JS145, JS160, JS200, JS220 (with DieselMax / EcoMax engines) |
The list above is for reference. It is crucial to ensure that your machine is fitted with a JCB DieselMax or EcoMax engine.
Always install the manifold with a new, genuine gasket. To prevent nuts from seizing on the studs in the future, which is a mechanic's nightmare, coat the threads with HYPTRON copper anti-seize compound. We strongly recommend replacing the manifold studs and nuts with new ones as well.
The exhaust manifold gasket prevents leaks of hot, toxic exhaust gases. A leak at this point leads to a drop in the exhaust pressure driving the turbocharger, which directly reduces engine power and increases fuel consumption.
Replace the gasket if you notice any of the following symptoms:
✓ Uncompromising Quality: Choose a Genuine JCB Part
By choosing a genuine JCB gasket, you are investing in 100% certainty and peace of mind. You receive a part designed specifically for the high thermal and pressure loads of DieselMax and EcoMax engines. This guarantees a perfect fit, maximum sealing, and durability that cheap replacements cannot provide.
Annoyed by the noise and loss of power? Don't ignore a leak!
A leaking manifold can lead to it burning out or even damaging the cylinder head. Order a genuine gasket today and restore full power and quiet operation to your engine!
Absolutely not. This multi-layered steel gasket is designed to be installed "dry". The use of any pastes or silicones can cause it to seat incorrectly and burn out quickly.
2. Will this gasket fit older machines with a Perkins engine?No, this model is exclusively for newer machines with a JCB DieselMax or EcoMax engine. Gaskets for Perkins engines have a different shape and part number.
