John Deere 430 round baler

[Robbie519]

Needing help to fix a gate locking problem. My John Deere 430 that I recently purchased will not lock the gate shut. The manuel advised to install an orifice into the density control to fix the problem. It was to slow the flow I'm guessing. But the locks still won't engage. The hydraulics need to close about 4 more inches to allow for the locking spring to caught. Any thoughts or advice would be greatly appreciated.

Is gate lock valve "opened fully"? What brand/model tractor are you operating baler on? Are belt lengths within spec's? Is gate twisted?
