Common Benefits of Hydraulic Oil Tanks

• The hydraulic oil tank stores hydraulic oil for supplying it to the hydraulic system during operation.
• It cools the hydraulic fluid by dissipating heat from the oil through air contact or cooling fins on the tank.
• The hydraulic fluid reservoir allows contaminants to settle. It provides a calm zone where dirt, water, and metal particles sink to the bottom.
• It provides space for oil expansion and leaves extra volume to accommodate oil expansion from temperature rise.
• The reservoir removes air from the fluid and allows trapped air bubbles in the returning oil to rise and vent out.

How to Use This

• Mount the tank securely on the truck frame using the included J-brackets and strap assemblies.
• Open the filler/breather cap and fill the tank with compatible hydraulic oil.
• Ensure the nylon strainer basket and cap are clean and free of blockage.
• Connect hydraulic lines using the NPT ports with plugs/diffusers as needed.
• During operation, the breather cap automatically vents air to avoid pressure build-up.
• Perform regular checks to monitor oil condition, level, and system performance.

Maintenance Tips

• Check oil level regularly to ensure it stays within the recommended range.
• Clean or replace the breather cap to avoid pressure buildup or gathering of impurities.
• Inspect oil condition for discoloration, smell, or impurities.
• Replace filters as needed to keep the hydraulic system clean.
• Check for leaks and tighten fittings to maintain system integrity.
• Avoid overfilling the tank to allow space for oil expansion.
