4TNV94/4TNV98 Yanmar Engine Cylinder Head - Hyundai R60 Dedicated

Hebei Keluo Construction Machinery Co., Ltd. has focused on the R&D and supply of core components for mini excavator engines for many years, specializing in original equipment manufacturer (OEM) replacement parts and technical support for mainstream mini excavator models. The company understands the stringent requirements of construction machinery maintenance for parts precision, durability, and stability, and has established a complete standardized management system from parts selection, processing technology, factory quality inspection to after-sales technical service. Relying on a stable and mature supply chain, ample inventory, and a professional technical team, the company enjoys high customer recognition and a good industry reputation in the field of mini excavator maintenance and overhaul parts.

The Hyundai R60 series, a classic and popular 6-ton mini excavator, includes mainstream versions such as the R60-7, R60VS, and R60-9. With its compact and maneuverable design, fuel efficiency, low failure rate, and wide adaptability, it is widely used in various precision operations and light-to-heavy-load conditions, including municipal road repair, landscaping renovation, farmland irrigation excavation, earthwork backfilling and leveling, old building demolition, and courtyard construction. It is a mainstay piece of equipment used extensively in urban and rural infrastructure projects. All models are equipped with Yanmar 4TNV94 or 4TNV98 four-cylinder water-cooled engines. These two engines share similar structural designs, offer high parts interchangeability, and have fully interchangeable cylinder heads, allowing them to adapt to both routine and short-duration heavy-load operation needs. As a core component of the engine for air distribution, heat dissipation, sealing, and pressure bearing, the cylinder head is constantly exposed to harsh working conditions on construction sites, including high temperatures, high vibrations, frequent start-stop cycles, and high dust levels. This makes it highly susceptible to problems such as air intake wear, oil/gas leakage, and water/oil leakage, severely impacting construction efficiency. Therefore, replacing the cylinder head with a high-quality, dedicated cylinder head is a crucial step in restoring equipment performance during major overhauls and maintenance.

Specifically designed for the operating conditions of the Hyundai R60 model, Hebei Keluo offers the 4TNV94/4TNV98 universal cylinder head, precisely adapted to the entire Hyundai R60 series. The product strictly replicates the original factory air intake, water, and oil passage layout, with accurate dimensions for key components such as valve holes, injector holes, and mounting bolt holes, perfectly matching the original factory assembly requirements.

This cylinder head is made of high-density, high-strength cast iron, integrally cast. The material is dense and uniform, free of sand holes and porosity, exhibiting excellent resistance to high temperatures, high pressures, vibration, and deformation. It can withstand the complex working conditions of frequent high-frequency operation of mini excavators for extended periods, and is less prone to structural damage such as cracking, warping, and leakage. After multiple high-precision CNC milling processes, the cylinder head sealing surface achieves extremely high flatness. The intake and exhaust manifolds have been optimized and upgraded, resulting in smoother intake and more thorough exhaust, effectively improving fuel atomization and combustion efficiency. This significantly addresses issues such as weak acceleration, sluggish operation, and high fuel consumption in the Hyundai R60, fully restoring the equipment's original factory performance.

To ensure installation quality and operational stability from the source, Hebei Keluo implements multiple rigorous factory testing processes for each 4TNV94/4TNV98 cylinder head, ensuring that every shipped product meets quality standards, operates stably, has a low failure rate, and a longer service life. The company has a large dedicated warehouse with year-round stock, providing customers with free one-on-one technical guidance. Hebei Keluo has become the preferred supplier for the maintenance and repair of Hyundai R60 excavators worldwide.
