The 1971 Case 580CK is a versatile and durable backhoe loader that has been a staple in construction and agricultural operations for decades. To ensure optimal performance and longevity, it's crucial to use the correct fluids in its various systems. This article provides a comprehensive guide to the recommended fluids for the 580CK, including hydraulic, transmission, and engine oils, along with practical tips for maintenance.
Hydraulic and Transmission Fluids: Case TCH
The hydraulic and transmission systems of the 580CK are designed to operate with Case TCH (Transmission, Clutch, and Hydraulic) fluid. This multi-purpose fluid is formulated to provide the necessary lubrication and performance for both the hydraulic and transmission components. Using the correct fluid is essential to prevent damage and ensure smooth operation.
The transmission and differential components of the 580CK require specific gear oils to function correctly. Using the wrong type of oil can lead to poor performance and potential damage.
The 580CK is equipped with either a gasoline or diesel engine, each requiring specific oil types and capacities.
The 1971 Case 580CK is a classic backhoe loader renowned for its versatility in construction and agricultural tasks. Proper fluid selection is critical to maintaining its longevity and reliable operation. This overview provides detailed guidance on hydraulic, transmission, differential, and engine fluids, along with practical maintenance tips.
Hydraulic and Transmission Fluids
The 580CK uses a combined hydraulic and transmission fluid system. The original specification is Case TCH (Transmission, Clutch, Hydraulic) fluid, which serves multiple functions: lubricating the transmission, engaging the clutch, and powering hydraulic components. Using the correct fluid prevents premature wear, overheating, and operational issues.
The 580CK features separate gear systems for the transmission and differential, each requiring proper lubrication to ensure smooth operation and prevent gear wear.
Depending on the engine type—gasoline or diesel—the 580CK requires specific oils to maintain efficiency and protect internal components.
The Case 580CK was introduced in the late 1960s as part of Case’s effort to offer a versatile backhoe loader for both industrial and agricultural markets. Its hydraulic systems were advanced for the era, combining transmission and hydraulic functions to simplify maintenance and operation. By the early 1970s, the 580CK had become a popular model with hundreds of units sold worldwide. Its robust design allowed many machines to remain operational decades later, provided fluids and maintenance were properly managed.
Summary
Proper fluid selection is essential for the 1971 Case 580CK. Using the correct hydraulic/transmission fluids, gear oils, and engine oils ensures reliability, extends the lifespan of components, and maintains operational efficiency. Regular inspection, adherence to specifications, and timely maintenance are key to keeping this classic backhoe loader functioning optimally.

This multi-purpose fluid is formulated to provide the necessary lubrication and performance for both the hydraulic and transmission components. Using the correct fluid is essential to prevent damage and ensure smooth operation.
- Capacity: The hydraulic system requires approximately 11 gallons of Case TCH fluid .
- Alternative Fluids: While Case TCH is recommended, some operators have successfully used Hy-Tran Ultra or other high-quality UTF (Universal Tractor Fluid) equivalents. It's important to ensure that any substitute meets the specifications of Case TCH to maintain system integrity .
The transmission and differential components of the 580CK require specific gear oils to function correctly. Using the wrong type of oil can lead to poor performance and potential damage.
- Transmission: SAE 10W-30 or a specified hydraulic/transmission fluid is recommended for the transmission system .
- Differential: SAE 90W gear oil is suitable for the differential. It's important to use gear oil that meets the specifications for hypoid gears to ensure proper lubrication and prevent wear .

- Hydraulic capacity: Approximately 11 gallons
- Recommended substitutes: Hy-Tran Ultra or other high-quality Universal Tractor Fluids (UTF) are acceptable if they meet Case TCH specifications
- Maintenance tip: Regularly check fluid levels and inspect for contamination or discoloration, which may indicate system wear or leaks
The 580CK features separate gear systems for the transmission and differential, each requiring proper lubrication to ensure smooth operation and prevent gear wear.
- Transmission: SAE 10W-30 or approved hydraulic/transmission fluid
- Differential: SAE 90W hypoid gear oil
- Recommendation: Always use oils meeting OEM specifications; synthetic blends can offer improved thermal stability in high-use conditions
Depending on the engine type—gasoline or diesel—the 580CK requires specific oils to maintain efficiency and protect internal components.
- Gasoline engines: SAE 30 or 10W-30, depending on ambient temperatures
- Diesel engines: SAE 15W-40 is common for diesel variants
- Best practice: Change oil and filters at regular intervals, monitor for leaks, and maintain proper coolant levels to prevent overheating
- Fluid inspection: Check all reservoirs for proper levels and contamination weekly
- Seal integrity: Older machines may develop leaks around seals; use compatible seal conditioners if necessary
- System flushing: Periodically flush hydraulic and transmission systems to remove sediment and metal particles, extending component life
- Operator training: Proper operation reduces fluid stress, especially in hydraulics during heavy lifting
