Part Explanation: A Gear Pump (e.g., FT700.58D.010 on a John Deere 8R Series Tractor, John Deere 8R Series FT700.58D.010 齿轮泵 / Трактор John Deere 8R серии FT700.58D.010 Шестеренчатый насос) is located in the hydraulic system and creates fluid flow to power various hydraulic functions.

Part Explanation: A Brake Pump (e.g., POMPAFRENID.19.05X30-32MIN on a Foton Lovol M250 Tractor, Foton Lovol M250 Tractor POMPAFRENID.19.05X30-32MIN 制动泵 / Трактор Foton Lovol M250 POMPAFRENID.19.05X30-32MIN Тормозной насос) is an essential component of the braking system, generating hydraulic pressure to actuate the brakes.

Problem: John Deere 6155R Tractor (John Deere 6155R 拖拉机 / Трактор John Deere 6155R) Hydraulic System Slow to Respond or No Lift

Symptoms: The tractor's implements (e.g., loader, rear hitch) lift very slowly, struggle to lift at all, or exhibit jerky movements. The hydraulic pump might also emit a whining noise.

Possible Causes & Solutions:

1. Low Hydraulic Fluid Level: This is the most common cause. Check the hydraulic fluid reservoir and top it up to the recommended level. Ensure you use the correct type of hydraulic fluid specified by the manufacturer.

2. Clogged Hydraulic Filter: A dirty or clogged hydraulic filter restricts fluid flow, leading to reduced hydraulic performance. Replace the hydraulic filter (e.g., 00034705FILTROOLIOIDRAULICO) as per the maintenance schedule.

3. Worn Hydraulic Pump: Over time, the internal components of the hydraulic pump (e.g., FT700.58D.010) can wear out, leading to a loss of pressure. If fluid levels are good and filters are clean, a worn pump might need replacement or rebuilding.

4. Faulty Relief Valve: The hydraulic relief valve is designed to prevent over-pressurization. If it's stuck open or malfunctioning, hydraulic pressure will escape, leading to poor performance. This would require inspection and possible replacement of the valve (e.g., a multi-way valve like TC03582410001FP-L15E).

5. Leaking Hydraulic Cylinder Seals: Internal or external leaks in the hydraulic cylinders (e.g., 00061713) can cause a loss of pressure and slow operation. Inspect cylinders for visible leaks and consider a cylinder repair kit if seals are the issue.

Action Plan:

1. Check hydraulic fluid level and condition.

2. Inspect and replace hydraulic filters if necessary.

3. Listen for unusual noises from the hydraulic pump.

4. If basic checks don't resolve the issue, consult a qualified mechanic to diagnose potential pump or valve failures.
