FAQ 

Q1: Can this locking screw rod fit ZL50GN loader directly?
A1: Part No.252000119 is specially for ZL50G and ZL50GL. ZL50GN has different specification of adjusting locking mechanism. Direct interchange is not recommended. Verify old part number before ordering.

Q2: Can I keep using it if the threads are slightly worn?
A2: Worn threads reduce locking capacity. It is easy to loosen under vibration and brings hidden dangers. Timely replacement is recommended.

Q3: Are matched lock nuts included in the parcel?
A3: Standard package only contains the locking screw rod. Nuts and washers are optional parts. You may order supporting fasteners separately.

Q4: How to deal with slight rust on the screw rod?
A4: Clean light surface rust and apply grease for protection. Replace immediately if threads are damaged, the rod is elongated or cracked.

Q5: What should be noted during installation?
A5: Clean thread dirt before assembly and apply a small amount of grease. Tighten evenly and avoid excessive force on one side. Recheck preload after locking and inspect regularly for loosening.
