The Role of the Cylinder Head in Engine Performance

The cylinder head sits at the apex of the engine block. Its primary role is to contain the high pressure generated when the piston reaches top dead center. By managing the fuel mixture and timing of the valves, the head converts chemical energy into mechanical energy to drive the machine forward.

Cracks or warping in these heavy machinery engine parts can compromise fuel efficiency and lead to excessive oil consumption. Choosing quality engine parts from IMARA ensures engines run smoothly, preventing premature engine wear and protecting your fleet's productivity.

Comprehensive Cylinder Head Range with Competitive Pricing

We offer a wide variety of replacement parts for all major engine types. By providing competitive pricing without sacrificing quality, we help fleet managers maintain peak engine performance across their entire operation.

Complete Cylinder Heads

Complete units are supplied fully assembled with valves, springs, and seals. This eliminates the technical difficulty of matching individual aftermarket engine parts and ensures all internal components are perfectly seated for immediate installation.

Bare Cylinder Heads

Our bare cylinder heads are new castings provided without internal hardware. These are the ideal replacement parts for an internal combustion engine when your current valves and springs are still within manufacturer tolerances.

Performance-Tested Castings

Cylinder head castings must resist thermal stress. Poor-quality metal often cracks between the intake ports and exhaust valves. Our castings are produced through controlled metallurgical processes to ensure they withstand the high pressure of modern diesel engines.

Built for High-Temperature and High-Load Applications

Australian heavy equipment often operates in extreme heat, where thermal cycling is constant. Material density is the only defense against the warping that leads to head gasket failure.

IMARA Engineering Supplies sources heads made from high-grade alloys that improve heat dissipation. This ensures oil pressure remains stable and the fuel mixture ignites predictably within the combustion chamber, keeping your engines performing at their limit.

Compatibility and Correct Fitment

Variations in engine type mean that even small differences in port design can lead to localized overheating. Correct selection prevents "Machine Off Road" (MOR) delays and ensures your engines are running at maximum efficiency.

Our technical team utilizes OEM databases and serial number cross-referencing to ensure every cylinder head matches your machine’s requirements. This precision ensures the head works in harmony with piston rings and spark plugs (where applicable) to maintain a perfect seal.

Maximizing Cylinder Head Service Life

Proper maintenance is the key to avoiding engine wear. To keep your diesel engines in top condition and prevent the engine from burning oil, we recommend:

• Torque Procedures: Use the correct sequence to ensure even pressure across the engine block.
• Coolant Quality: Prevent corrosion within the internal passages to protect intake ports.
• Monitor Heat: Address even minor overheating immediately to prevent warping the high-quality casting.
• Clean Ignition: For relevant engines, ensure spark plugs are clean to maintain optimal power output.

Supporting Australia’s Construction and Mining Sectors

We understand the heavy loads placed on internal combustion engines in mining and earthmoving. Our cylinder heads are tested in real-world conditions to handle the dust and vibration of the Australian landscape. We provide the heavy machinery engine parts necessary for fleet operators to minimize wear and tear.

Fast Dispatch and Reliable Logistics

Cylinder head failure is an emergency. We prioritize fast order processing and an optimized supply chain for rapid dispatch across Australia.

Our goal is to deliver your engine parts quickly to restore your machine’s mechanical energy and get you back to work.
