hydraulic oil/bleeding

How do you bleed a juice ride and what kind of oil do you get? Also, how do you maintain your pumps and when do you change oil?

I think the questions already been asked but I will ask again. Thanks UR.

I use the hydro fluid in the big buckets. If its a brand new pump go ahead and take the backing plate and tank off. You will see your gear when remove all that. Check for the plugs on the back and bottom of the head. If installed remove. Then if you can stick your finger down the pressure port before you put fittings on and check for the plug on the pressure port of the gear. If you are not sure if its there go ahead and take the gear off it will be the top four bolts and check it. If the plug is installed remove. Install the gear ensuring the o-ring pressure seal is there. Torque it down evenly don't over torque it. Put everything back together. Install the pump and fittings. Hook up the hoses and disconnect the one you are bleeding at the cylinder. Do one at a time. Jam it down an empty oil jug or something to catch it where it wont splash back out. Tap the switch until you get a steady squirt. Install hose and repeat for the others top of the tank until its one inch below the port. then just tap it up and down a couple of times to bleed the return.


If you ever have to work on your pump it is best to invest in some caps and plugs from a hydro shop. That way you don't have a open line and get excessive air into it. If you ever drain the tank or work on the fittings and drain the fluid from them. Cap the lines and when you reinstall the pump and hold down the dump for that pump and tap the switch for the same pump to bleed the air that entered the gear,fittings and dump. This can be down if you have multiple switches for each pump. I can only do my rear that way but with some thinking you can just do it by having someone run a hot wire to the dump while you tap the switch.

By the way if you have never worked with hydros before make sure you install the checkvalve in the correct spot and the correct direction. That is always a rookie mistake.
