Complete engine cylinder head designed for a wide range of compact JCB machinery. This is a proven, high-quality aftermarket replacement manufactured by AZERI PARTS, part number 02/634866. The offered product is a fully assembled (complete) version – it comes factory-fitted with valves, springs, valve seals, and collets. This makes the cylinder head ready for immediate installation on the engine block. Its precise manufacturing and excellent sealing are essential for maintaining proper compression and optimal combustion.
Technical Features:
- Time and Cost Savings: A complete, pre-assembled head eliminates the need for expensive and time-consuming grinding of old valves, replacing guides, or machining the surface at a machine shop.
- High Thermal Resistance: Cast from an optimally selected alloy, it is highly resistant to thermal stress, preventing micro-cracks and deformation.
- Perfect Fitment: The precisely machined mating surface guarantees excellent cooperation with the head gasket, eliminating the risk of blow-by and coolant leaks.

Technical Tip: Even though the cylinder head (02/634866) is complete and ready to install, absolutely check the condition and flatness of the engine block's upper surface prior to mounting. Always use a new head gasket of the correct thickness (based on piston protrusion) and completely new cylinder head bolts. Bolts must be tightened gradually, strictly following the sequence and torque specifications provided in the engine's service manual. Improper tightening is the most common cause of gasket failure.
