loader wont raise

[Tombo]

I tried a search on this, but came up nil...

I have a 4110 hydro with a 410 loader. The loader was operating normally, then, as I drove into a pile of gravel, I found I could not raise it. I was able to curl the bucket, dump th eload and back away, but the up/down function is inoperable. I have plenty of hydro oil in it. The backhoe, steering and 3PH rockshafts all seem to be OK. What is wrong with this thing?

Thanks in advance!!!

make sure your quick connects are tight. they can look tight but not be all the way in. i am a newbie and discovered this recently.

I doublechecked: even took them off and put them back on to be sure, but nothing. It has down pressure, but no up.

I had a similar thing happen to my 410 loader and found that I needed to replace the "guts" on one of the quick connect assemblies. When I explained to the dealer the problem he knew right away what was wrong. Not saying it is your solution but it sure took care of my situation.

It definatly sounds like a QC (quick coupler) problem. Try switching the hoses and see if the problem switches also.

Yep......double check your quick couplers.......I have had tis problem from time to time and a coupler that came loose was the culprit every time!!!

Do you hear the pump whine when you ask for up? Then its probably a bad quick connect

 

[Tombo]

the pump does whine. I will call te dealer tomorrow. Thanks for all of the replies!!!

Change your hydraulic filter

Change your hydraulic filter

I'm pretty sure if the hydraulic filter was plugged he would have lost more than one function on the loader.
