jerky loader

crobins1 · Dec 30, 2018

I just purchased a jubilee that came with a loader it was all in pieces. I was able to put it all back together but now when I operate the loader it is jerky. at first I thought it had the wrong hyd fluid so I drained it and added ford f/a fluid. btw it is a davis skyline loader. I also cleaned the screen for the pickup it was plugged up. im hoping the pump is still good any suggestions. oh btw I have tried to dead head the pump several times thinking this would help to bleed the system of air.

Unless your pump is starving or going south, I'm going to guess you still have trapped air in the system.

My guess would also be air.

Dead heading will not help bleeding, keep cycling it.

im not sure how the pump went does it matter if it could be upside down? the inlet and outlet is correct I wouldn't think it would matter on a hydraulic system

Depending on what type pump, it could make a difference on suction / discharge.

Usually the inlet or suction side is larger
opening than the pressure side. Yes it
makes a difference to the sealing of the
pump internals. Sounds like you are
sucking air somewhere. Is hydraulic fluid
foaming? If so. Indicates sucking air.

I live in the South and resent that everything that is going bad is referred to as going South. Just kidding. I understand why the term is
used and everyone understands what it means.

here is what my pump looks like as you can see it has a 3 hole gland that mounts it. anyone know what kind of pump this is

Maybe in the southern hemisphere they say "It went north".

We usually say it went down the toilet-maybe to Australia or New Zealand. During the Civil War going South is what Gen'l Sherman did.
