Frequently Asked Questions

What size PTO hydraulic pump and reservoir do I need for my RV camper?

For typical RV leveling jacks and slide-outs, a pump with 8 to 12 GPM at 540 RPM and a 5 to 8 gallon reservoir is usually sufficient. Larger systems with hydraulic motors may require 14 to 16 GPM. We recommend matching the flow to your system’s maximum demand and ensuring the reservoir is at least 1.5 times the pump’s output per minute for cooling.

Can I use a tractor PTO hydraulic pump with a non-tractor engine?

Yes, as long as you have a PTO shaft that rotates at 540 RPM (or 1000 RPM) and the correct SAE mount. Some RVers use a separate engine with a PTO adapter. However, ensure the pump’s rotation direction matches your PTO (usually clockwise).

How do I maintain a PTO hydraulic pump and reservoir?

Regularly check the oil level and condition, change the return line filter annually, and inspect hoses for leaks. Drain and replace hydraulic fluid per the manufacturer’s schedule, typically every 500 hours. Keep the reservoir clean and the breather cap unclogged.

What safety features should I look for in a PTO hydraulic pump combo?

Look for a pressure relief valve to prevent overpressure, a return line filter to keep oil clean, and a suction strainer. Some units include a pressure gauge port for monitoring. Ensure the reservoir has a proper vent to avoid pressurization.

Can I mount a PTO hydraulic pump and reservoir in an RV compartment?

Yes, but ensure adequate ventilation for heat dissipation. The reservoir should be mounted securely to prevent movement. Also, consider noise and vibration isolation. Some owners install a remote oil cooler for extended operation.
