Introduction
The Clark Michigan 175A wheel loader, produced from 1962 to 1985, stands as a testament to the durability and engineering prowess of its time. Manufactured by Clark Equipment Company, this machine was designed to tackle the demanding tasks of construction, mining, and material handling. Despite its age, the 175A remains a valuable asset for those who appreciate its robust construction and the legacy it represents.
Historical Background
Clark Equipment Company, founded in 1916 by Eugene Clark, initially gained prominence for its development of lift trucks. By the 1950s, the company had expanded into the wheel loader market under the Michigan brand name. The introduction of the 175A model in the early 1960s marked a significant advancement in wheel loader design, featuring improved lifting capacities and enhanced operator comfort. The 175A was part of a series that included models like the 75A and 125A, all of which were well-received in the marketplace .
Specifications
The Clark Michigan 175A is equipped with a General Motors 6V-71 diesel engine, delivering approximately 160 kW (215 hp) of power. This engine provides the necessary strength for demanding tasks. The loader has a weight of 16.76 tons and can achieve a transport speed of up to 40.4 km/h. Its transport width is 2.74 meters, and the turning radius is 7.73 meters, making it suitable for various job site conditions .
Common Issues and Maintenance
Owners of vintage machinery like the 175A often encounter specific challenges. One common issue is the wear of steer stops, which can lead to oversteering and increased stress on universal joints. Proper maintenance of these components is crucial to prevent premature wear and ensure smooth operation. Additionally, the front differential is not limited slip unless modified, which can affect traction in certain conditions .
Another area of concern is the transmission. Some models, particularly the 175AD, have been reported to experience reduced pushing power and transmission slippage under load. This can be attributed to issues such as slipping torque converters, worn hydraulic pumps, or clogged filters. Regular maintenance, including timely oil changes and filter replacements, is essential to address these issues .
Restoration and Preservation
Restoring a Clark Michigan 175A requires a commitment to preserving its original design while upgrading components for modern performance standards. Access to parts manuals and operator guides is invaluable during this process. For instance, the Historical Construction Equipment Association provides resources for vintage machinery enthusiasts .
Conclusion
The Clark Michigan 175A wheel loader embodies the strength and resilience of mid-20th-century engineering. Its continued operation and restoration serve as a tribute to the craftsmanship of its era. For those dedicated to maintaining and restoring vintage machinery, the 175A offers both challenges and rewards, ensuring that its legacy endures for future generations.
