Machine Series: CASE 580 Series Backhoe Loader

The BT8850 KS / N 9025 / 84239751 / 1346028C1 Hydraulic Oil Filter is a genuine CNH factory-original filter designed to protect the hydraulic and transmission systems of CASE 580 backhoe loaders.

These four part numbers represent the SAME filter and are interchangeable references used in different catalog systems and production periods. There is NO superseded number — only multiple interchangeable part numbers referring to identical specifications.

This filter is engineered to remove harmful contaminants from hydraulic oil including:

• Metal wear particles

• Dust and dirt

• Sludge deposits

• Oxidation residues

Proper filtration ensures stable oil pressure, smooth shuttle shifting, controlled torque converter performance, and extended system lifespan.

Manufactured to strict OEM standards, this genuine filter guarantees:

• Correct micron filtration rating

• Proper oil flow volume

• High burst pressure strength

• Reliable sealing performance

• Long service durability

Using non-genuine filters may result in restricted flow, leakage, or premature clogging which can cause severe hydraulic or transmission damage.

FUNCTION & IMPORTANCE 

This hydraulic filter protects critical components including:

• Hydraulic pump

• Torque converter

• Shuttle transmission

• Transaxle cooling circuit

• Control valves and cylinders

Failure to replace the filter on schedule may cause:

• Delayed forward/reverse engagement

• Transmission overheating

• Pressure instability

• Internal clutch wear

• Major overhaul costs

Routine maintenance replacement is strongly recommended.

 COMMON PROBLEMS & TROUBLESHOOTING 

Replace immediately if experiencing:

• Weak hydraulic response

• Jerking during operation

• Oil overheating

• Dark or burnt-smelling hydraulic oil

• Abnormal transmission noise

Ignoring these symptoms may lead to costly internal damage.

INSTALLATION & SERVICE TIPS 

• Clean filter mounting base before installation

• Lightly lubricate rubber gasket with clean oil

• Tighten according to manufacturer specification

• Start engine and inspect for leakage

• Monitor system response after replacement
