The IH 175C loader was built with durability in mind, equipped with a robust engine and strong hydraulics, which made it ideal for a variety of tasks.
The 175C loader specifically was designed for material handling, especially in environments where lifting and moving heavy loads was required. With a standard bucket capacity of around 2 cubic yards, it could easily lift and transport a wide range of materials such as gravel, sand, and dirt. Its versatility in lifting, digging, and moving materials made it a favorite for many operators.
Common Challenges with the IH 175C
While the IH 175C is known for its reliability, as with all older machinery, it comes with a unique set of challenges. Operators and owners of these machines often encounter specific issues that require careful attention and proper repairs.
To keep the IH 175C running efficiently, regular maintenance and attention to detail are key. Here are some useful tips to ensure longevity and performance:
While the IH 175C loader is an older model, its durability and power continue to make it a valuable tool for those who know how to maintain it. With careful attention to the hydraulic system, engine, transmission, and structural components, operators can extend the life of their loader and continue to get reliable performance from it.
Operators who take pride in caring for these older machines often find that they can still offer excellent service, provided that the necessary maintenance and repairs are done. In the world of heavy equipment, a well-maintained loader like the IH 175C can remain a workhorse for many years, proving that sometimes, older machinery can be just as good, if not better, than newer models.

Common Challenges with the IH 175C
While the IH 175C is known for its reliability, as with all older machinery, it comes with a unique set of challenges. Operators and owners of these machines often encounter specific issues that require careful attention and proper repairs.
- Hydraulic System Issues
One of the most common issues in older loaders like the IH 175C is problems with the hydraulic system. Over time, the hydraulic pumps, cylinders, and hoses can wear out or leak, reducing the loader’s ability to lift heavy loads efficiently.- Hydraulic Leaks: Leaking hoses, pumps, and seals can cause a drop in hydraulic pressure, which means the loader might struggle to operate its arms or bucket. Regular inspections are necessary to identify and repair these leaks before they escalate into bigger problems.
- Hydraulic Fluid Quality: Contaminated hydraulic fluid can cause blockages in the system, making the machine less responsive. Using clean, high-quality hydraulic oil and ensuring the fluid is changed regularly can help avoid this.
- Hydraulic Leaks: Leaking hoses, pumps, and seals can cause a drop in hydraulic pressure, which means the loader might struggle to operate its arms or bucket. Regular inspections are necessary to identify and repair these leaks before they escalate into bigger problems.
- Engine Performance and Maintenance
The engine in the IH 175C is designed to provide substantial power for the loader’s operations. However, after many years of service, engine components can wear down, leading to issues such as loss of power, overheating, or difficulty starting.- Starter Motor and Battery: The starter motor and battery are often the first components to fail in older machines. Over time, the battery can lose its capacity to hold charge, and the starter motor may become sluggish or entirely fail. Regular testing of both the battery and starter motor can prevent unexpected breakdowns.
- Overheating: Overheating can occur if the radiator or cooling system is clogged or if the engine’s cooling fan is malfunctioning. Ensuring the radiator is cleaned and the cooling system is flushed periodically can help maintain optimal engine temperature and prevent damage.
- Starter Motor and Battery: The starter motor and battery are often the first components to fail in older machines. Over time, the battery can lose its capacity to hold charge, and the starter motor may become sluggish or entirely fail. Regular testing of both the battery and starter motor can prevent unexpected breakdowns.
- Transmission and Powertrain Problems
Transmission issues are not uncommon in older machines, and the IH 175C loader is no exception. The transmission system, responsible for transferring power from the engine to the wheels, can develop issues if the fluid levels are low or the components are worn.- Transmission Fluid: Low or dirty transmission fluid can lead to slipping gears, making the loader difficult to operate. Regular fluid checks and changes are essential for keeping the transmission system running smoothly.
- Powertrain Wear: Over time, the powertrain components, including the clutch, gear system, and axles, can experience significant wear and tear. Worn-out parts can cause the loader to move erratically or fail to change gears properly.
- Transmission Fluid: Low or dirty transmission fluid can lead to slipping gears, making the loader difficult to operate. Regular fluid checks and changes are essential for keeping the transmission system running smoothly.
- Structural Wear and Tear
As with any loader, the IH 175C experiences wear on its structural components, especially the bucket, lift arms, and frame. Regular inspection for cracks, rust, or deformation is necessary to maintain structural integrity.- Bucket and Arm Wear: The bucket and lift arms are subjected to constant stress when lifting heavy materials. Over time, these components can wear down, resulting in a decrease in performance. Ensuring the bucket is properly maintained and repairing any damage early can prevent larger issues.
- Frame and Chassis: The frame and chassis of the loader can develop cracks or bends due to prolonged use or harsh working conditions. Regular inspections and welding repairs can help extend the machine’s life.
- Bucket and Arm Wear: The bucket and lift arms are subjected to constant stress when lifting heavy materials. Over time, these components can wear down, resulting in a decrease in performance. Ensuring the bucket is properly maintained and repairing any damage early can prevent larger issues.
- Electrical System Troubles
Older loaders like the IH 175C are often prone to electrical issues, such as faulty wiring, blown fuses, or malfunctioning lights and sensors.- Wiring and Connections: As the wiring ages, it can become brittle or corroded, causing electrical components to malfunction. Regular inspections of the wiring and connections, particularly in harsh environments, can prevent electrical failures.
- Fuses and Relays: Blown fuses and faulty relays are common issues in older loaders. If the loader’s electrical system stops working, checking and replacing the fuses and relays can often resolve the issue.
- Wiring and Connections: As the wiring ages, it can become brittle or corroded, causing electrical components to malfunction. Regular inspections of the wiring and connections, particularly in harsh environments, can prevent electrical failures.
To keep the IH 175C running efficiently, regular maintenance and attention to detail are key. Here are some useful tips to ensure longevity and performance:
- Regular Fluid Changes: Changing the hydraulic fluid, engine oil, and transmission fluid at regular intervals can help prevent a number of issues, including leaks, overheating, and poor performance.
- Hydraulic System Maintenance: Ensure that all hydraulic hoses and seals are checked regularly for signs of wear or leaks. Replacing worn-out parts and using quality hydraulic fluid can extend the life of the system.
- Engine Cooling System Care: Clean the radiator and check the cooling system regularly to avoid overheating. Ensure that the cooling fan is operating correctly and that coolant levels are maintained.
- Transmission Fluid Monitoring: Regularly check the transmission fluid and replace it if necessary. This will help maintain smooth gear shifts and prevent transmission problems.
- Inspect Structural Components: Regularly inspect the bucket, lift arms, frame, and other structural components for signs of wear or cracks. Weld repairs or part replacements can prevent costly downtime.
- Electrical System Checks: Regularly inspect the electrical system, including fuses, wiring, and connections. Replace any corroded or damaged parts to ensure reliable operation.
