|Bob Haight||1976 Case 580c. Bucket willnt level. Control lever willnt stay in detent when pulled toward operator. all other functions ok. Have 12v to magnetic detent & thru to grd. Applied 12v to detent without success. ???
|AJ||The return to dig position is mechanical till the linkage closes the switch & energises the solenoid which in turn pulls the valve to the neutral position and the lever kicks out,look at the linkage at where the over center cam is,it is not locking,there maybe something worn or need adjusting.
|Bob Haight||UPDATE On Bucket Leveler:
Removed loader control valve. Placed screwdriver through bucket spool linkage hole to prevent spool from turning. Removed magnetic detent housing end plug, removed detent stud nut & washer,loosen spring cap lock nut, removed spring cap with magnetic detent. The detent stud was rusty possibly not allowing the detent stud to move against spring pressure to detent.
Cleaned, lubricated detent stud & reassembled. Bench tested with 12v to magnetic detent & manually pulled spool into detent position. The spool stayed in detent untill 12v disconnected. Repeated test several times with same results. Reinstalled loader control valve & with key on to provide 12v. Tested as above by grounding other detent wire & moving lever to detent. Detent released when ground removed. Connected ground wire. Started & cycled bucket several times. Worked as designed!! 12v is supplied to to the magnetic detent with key on. It is controlled by the return-to-dig micro switch located on the right front boom. The adjustable switch is controlled by the actuator rod to automatically reposition the loader bucket to the digging position. Comments appreciated.
