FAQ 

Q1: Can this front grease tube fit ZL50GN loader directly?
A1: Part No.252102064 is specially for ZL50G and ZL50GL. ZL50GN has different front hinge lubrication structure. Direct interchange is not recommended. Verify old part number before ordering.

Q2: Can a cracked or bulging hose keep working?
A2: Damaged hose will leak grease and cause lubrication failure. The front pin may seize and lock the bucket. Immediate replacement is required.

Q3: Are matching grease nipples included?
A3: Standard package only contains the grease tube assembly. Grease nipples and clamps are optional parts. You can order them separately.

Q4: How to deal with leakage at connector thread?
A4: Tighten the thread and seal with a small amount of PTFE tape. If leakage occurs at the crimp root, replace the whole tube assembly.

Q5: What should be noted during installation?
A5: Reserve swing clearance and avoid tensioning the hose. Keep away from bucket moving path and sharp edges to prevent cutting. Regularly check hose aging and connector leakage.
