Re: 4200XL hydraulic issues

The verdict was an incorrectly assembled pressure relief valve....apparently I had messed with it and not put it back correctly. She's up and running again after about 5 years on the shelf.

4200xl old problems

So I got this excavator back in early 2015 or 2016. I had a servo go bad which was giving me a lot of crazy feedback causing tracks to move, carriage rotation, etc. So I replaced the servo with a...

Re: 4200XL hydraulic issues

So, I replaced the oil with Mobil 24. That did not solve my issue. The pump motor seemed to strain a bit more. It does sound like there is load on the pump motor when operating functions. Everything...

Re: 4200XL hydraulic issues

I messed with the valve and moved it one or two splines towards being closed more. It seemed to help some and it started moving a little more. It still isn't where it was though. I'm thinking another...

Re: 4200XL hydraulic issues

I will try to adjust the valve by hand once I get off and see if that works. Hopefully, that is the issue and I can get it figured out. I read on an australian forum a guy was having similar issues...

Re: 4200XL hydraulic issues

Ok, so I drained the system and refilled with fresh 32 oil...but the issue is still there. It's as if not enough fluid is getting to the cylinders to move the rams. It will move a tiny bit(3-4mm) but...

Re: 4200XL hydraulic issues

I've checked radio settings and all seem to be correct. The servo is set to move 120%. I did center the servo up before installing into the valve. I put the set screw back facing down towards the...

Re: First Conversion Attempt

Cooper, I just realized a few months back that I like dark beer. Such a nice beverage. And RCP57 thanks for the tip man. I will definitely have to take a gander at some HK escs.
