Do I need to bleed my Hydraulics and How?

Iplayfarmer · Oct 2, 2005

As I posted in another thread, I had my tractor, including the hydraulic system, torn apart for almost a month. It's all back together again, but now what do I do with the hydraulic system?

I drained at least a gallon of fluid. After putting new fluid in, do I need to bleed the system? How do I do this?

I've got a 3 point hitch and an aftermarket front end loader that run off the hydraulic system.

You don't do anything different than when you change your hyd fluid & filter.
Just fire it up and run everything through their paces. Any air in the system will work its way out.

I was hoping someone would say that.

Gday, Just something else to add, Both the loader and the 3 point hitch have single acting rams so make sure both are at their lowest position befor topping up the hydraulic oil.
If you have a hydraulic ram on your bucket then this is double acting so it dousent matter what position it is in, It wont affect the oil level.

Single acting? Double acting?

Maybe I understand this wrong.

I know I can lift the front tires off the ground by tipping the bucket down and then putting the lift arms all the way down. I thought this could only be done with a double acting ram.

Help me out. What's the difference?
