deutz engine 912 1011 1012 and 1013 cylinder head

The cylinder head of Deutz 912, 1011, 1012, 1013 is made from a high-strength aluminum alloy capable of withstanding operating temperatures up to 280°C. Optimized water and oil channels improve heat dissipation by up to 35% compared to similar designs. The average wall thickness is 12 mm, and M10 bolts with 70 Nm torque secure the head. Valve stem height is 38 mm with a guide diameter of 10 mm, extending component life up to 8,000 operating hours. A multi-layer head gasket maintains engine compression between 20 and 24 bar, preventing combustion gas leaks and ensuring stable performance.

Internal oil channels in these cylinder heads support a flow rate of 12 liters per minute at 3.5 bar pressure, ensuring proper bearing lubrication. Valve timing is calibrated to 0.1 mm precision to optimize fuel efficiency. The air-oil cooling system limits valve and seat temperature to 260°C. Cylinder head compressive strength under DIN 1691 testing reaches 180 bar. Flow geometry enhances combustion turbulence, improving thermal efficiency by 7%. These heads allow quick service, enabling valve replacement in under 90 minutes, simplifying routine maintenance.

Volvo loader L90 and L120 stock cylinder head

The main stock cylinder head for Volvo L90 and Volvo L120 Loader is made from high-strength gray cast iron, designed according to DIN 1691 standards. The total length of the cylinder head is 720 mm for the L90 and 745 mm for the L120. The wall thickness between cylinders is 12 mm, capable of withstanding pressures up to 180 bar. The weight of the L90 cylinder head is approximately 85 kg, and the L120 is about 92 kg. Cooling and oil channels are engineered to ensure optimal heat transfer and prevent local hotspots. Main bolt threads are M12 with a depth of 35 mm, having a minimum tensile strength of 900 N/mm².

The stock cylinder head features precise vent channels to reduce internal pressure and prevent cracking. The mating surface with the engine block is CNC-finished with a tolerance of 0.02 mm. Oil and coolant passages are evenly distributed to all cylinder areas. Intake valve diameter is 34 mm, exhaust 29 mm, with each valve weighing about 1.1 kg and heat resistance up to 550°C. Installation and replacement are possible with standard Volvo tools, and stock quality is verified through hydrostatic pressure and visual inspections.

6BT oversized cylinder head gasket

The 6BT oversized cylinder head gasket is designed with a 102 mm inner diameter and 1.2 mm thickness. The core is multilayer steel with nickel coating and a heat-resistant elastomer layer up to 300°C.
