description

This 803604510 oil reservoir is matched for brake system of XCMG ZL50G and ZL50GL wheel loader. It is welded from steel plate, with filling port, breather, outlet and oil level indicator. It compensates volume change of brake fluid caused by temperature fluctuation and supplies oil to booster pump to avoid air entering the brake circuit. Mounting bracket and port layout follow OEM drawings for direct replacement. It is compatible with original brake pipes and brackets without pipeline modification. Every tank passes pressure leakage and weld inspection. Reinforced structure resists vibration and muddy site conditions, preventing brake fluid emulsification and brake failure.

FAQ 

Q：Can leaking reservoir be kept in service?
A：Not recommended. Brake leakage is high-risk. Replace it immediately.

Q：What causes cloudy, milky brake fluid?
A：Water enters the tank via breather or cap seal. Drain and replace fluid, check reservoir seal.

Q：What if the breather is clogged?
A：Negative pressure inside, poor oil supply, spongy brake pedal and tank deformation risk.

Q：Can I weld and reuse leaking tank?
A：Not recommended for brake parts. Weld repair has re-cracking risk.

Q：How to store spare reservoir?
A：Store in dry area, cap ports and avoid impact.

Q：Is spongy pedal always caused by reservoir?
A：Check air in circuit, booster and pipeline leakage first.

Q：How to maintain the reservoir?
A：Check fluid level and leakage daily; inspect breather and replace brake fluid on schedule.
