Hi Folks,
I need to consult with the collective wisdom of the TBN community on an issue I'm having with my 2005 JD 3520 with 527 hours and a 300X loader on it.
The issue is that the loader bucket is curling very (extremely) slow now. It is very slow in both curling up and curling down, and I must apply lots of pressure on the loader control lever to get the bucket to move at all; almost to the point of bending the actual lever.
The 3 point and the loader lift cylinders work just fine.
Here's what I've done to troubleshoot the issue:
- Confirmed the correct amount of hydraulic fluid
- Disconnected and reconnected the hydraulic line couplers
- Inspected the hydraulic hoses and connectors for leaks
- Confirmed that the SCV lock lever is in the unlocked position
- Tested the bucket curl at various engine RPMs including PTO speed
- Greased all loader connections
The 3520 manual suggests that the suction side filter should be replaced or to check for water if the hydraulic performance is poor. Since the 3 point and the loader lift cylinders work fine, I'm not sure that either of these are the issue. Plus, the hydraulic filter was replaced at 400 hours.
Anyone have any suggestions on this?
Much appreciated!
