Buy HITACHI EX EX-2 EX-3 EX-5 ZAXIS SERIES REAR CRANKSHAFT SEAL 135 X 99 X 15MM | Tonkee®

The rear crankshaft seal in these Hitachi models is a precision-engineered component designed to fit snugly into the rear of the engine block.

Its dimensions, 135 x 99 x 15mm, ensure a perfect fit within the engine, sealing the gap between the crankshaft and the engine block. This seal is constructed from high-quality materials, often including rubber or silicone compounds, which offer excellent resistance to heat, oil, and other contaminants commonly found in an engine environment.

One of the primary functions of this rear crankshaft seal is to prevent oil leakage from the engine. The engine's crankshaft is constantly rotating and generating mechanical energy to drive the machine's various components. In the process, it splashes and moves oil around the engine. Without a reliable seal, this oil could escape, leading to reduced lubrication within the engine, increased friction, and potential damage to critical engine components. Therefore, the seal's role in maintaining oil integrity is crucial for the long-term health and performance of the machinery.

Furthermore, this seal serves as a barrier to prevent contaminants, such as dust, dirt, and debris, from entering the engine. These contaminants can be detrimental to the engine's internal components, leading to increased wear and tear, decreased efficiency, and potentially costly repairs. By sealing the crankshaft area effectively, this rear seal safeguards the engine against external pollutants, contributing to its longevity and reliability.

The dimensions of 135 x 99 x 15mm are meticulously chosen to match the specific requirements of the Hitachi EX and Zaxis Series engines.

The seal's outer diameter of 135mm ensures a snug fit within the engine block, preventing any gaps or leaks. The 99mm inner diameter corresponds to the size of the crankshaft, forming a tight seal around it. The 15mm thickness is designed to provide the necessary pressure to maintain a secure seal without causing excessive friction or resistance.

In terms of installation, replacing or installing this rear crankshaft seal should be carried out by skilled technicians with knowledge of engine maintenance. It typically involves removing various engine components to access the rear of the engine, carefully removing the old seal, and installing the new one with precision. Proper installation is crucial to ensure the seal functions as intended and provides the necessary protection against oil leaks and contaminants.
