OEM HITACHI EX100-2 TIMING GEAR CASE FLYWHEEL HOUSING CYLINDER HEAD M7 X 27 MM BOLT | Tonkee®

The timing gear case is a critical component in the internal combustion engine of the Hitachi EX100-2 excavator.

It houses the timing gears, which are responsible for synchronizing the opening and closing of engine valves and the injection of fuel into the cylinders. This precise timing is crucial for the engine to run smoothly and efficiently. The timing gear case also protects these gears from external elements and provides lubrication to reduce friction and wear. It is typically made of durable materials like cast iron or aluminum to withstand the rigors of heavy-duty construction work.

Flywheel Housing:
The flywheel housing is another integral part of the Hitachi EX100-2 excavator's engine. It encases the flywheel, which is a rotating mass that stores kinetic energy generated by the engine's pistons. The flywheel plays a crucial role in maintaining the engine's smooth operation by providing rotational inertia and helping balance the power output. Additionally, the flywheel housing serves as a protective barrier for the flywheel and helps maintain proper alignment with other engine components.

Cylinder Head:
The cylinder head is positioned at the top of the engine block and seals the combustion chambers. It contains the valves, springs, and other components responsible for controlling the intake of air and fuel and the exhaust of combustion gases. The cylinder head is subjected to extreme temperatures and pressures during engine operation, making it essential to use high-quality materials and precise machining for durability and performance.

M7 x 27 mm Bolt:
The M7 x 27 mm bolt is a specific type of fastener used in securing various engine components in the Hitachi EX100-2 excavator.

Its M7 designation indicates a metric thread size with a 7 mm diameter, and the 27 mm length specifies the threaded portion's length. These bolts are often made of hardened steel to provide the necessary strength and durability required for heavy-duty applications like construction equipment. They play a critical role in ensuring that the timing gear case, flywheel housing, and cylinder head remain securely attached to the engine block, preventing potential damage or malfunction due to loosening or vibration.

Importance of Proper Fastening:
Proper fastening of components is paramount in the construction of heavy machinery like the Hitachi EX100-2 excavator. Loose or improperly fastened components can lead to mechanical failures, increased wear and tear, and even safety hazards. Bolts like the M7 x 27 mm play a pivotal role in maintaining the structural integrity of the engine and ensuring that it operates reliably under demanding conditions.
