Q: What is included in the quality inspection before shipment?
A: Our inspection includes dimensional accuracy checks, material hardness testing, visual inspection for defects, and functional validation. A formal Machinery Test Report is generated, and we can arrange a live video outgoing-inspection to show you the parts and their packaging prior to dispatch.

Q: What are the recommended maintenance checks for rocker arms during engine service?
A: During valve clearance adjustment or cylinder head service, inspect the rocker arm for excessive wear on the pad that contacts the valve stem, scoring on the pivot bore, and any signs of cracking. Always replace rocker arms in sets per cylinder bank if significant wear is found on one, and ensure proper lubrication during installation.
