Inlet manifold gasket 320/05550 JCB Dieselmax, genuine

Inlet manifold gasket 320/05550 is a genuine JCB part for the JCB Dieselmax 444 engine. The card also lists 320/05521.

A gasket seals the joint between two parts. When a removed part goes back on, the old gasket is not reused: it has been compressed, lost its elasticity and will leak. Traces of oil, coolant or exhaust at the joint, drips or a whistle show the gasket needs replacing. Check the condition of the fixing bolts along with the gasket.

Specifications

Compatibility

The part is listed for JCB 3CX and 4CX backhoe loaders. The gasket fits between the inlet manifold and the head; a leak lets the engine draw unfiltered air. The catalogue also has the aftermarket version of this part. Other parts are in JCB Dieselmax engine.

Fitting

Use sealant only where the service manual calls for it; excess sealant can block passages. On hot joints, recheck the bolts after the engine has warmed up.
