The cylinder liner is the heart of the engine's combustion chamber. For Sinotruk HOWO trucks operating in heavy-load or high-temperature environments, the VG1246010028 cylinder liner is the essential replacement for any top-end overhaul. This is a "wet-type" liner designed specifically for the WD615 engine series (including 336hp, 371hp, and 420hp variants).
Our liners are centrifugally cast from high-phosphorus alloy cast iron, providing a dense structure that resists piston ring friction and prevents cavitation—a common issue in substandard HOWO parts. The inner wall features professional cross-hatch honing to ensure optimal oil film retention, reducing break-in time and extending engine life.

Installation Tips
-
Seal Inspection: When replacing the VG1246010028, always use new O-rings to prevent coolant from entering the oil pan.
-
Matching Parts: For a complete rebuild, we recommend pairing this liner with the VG1560030010 piston and VG1246030002 piston rings to ensure perfect clearance.
-
Genuine Assurance: Look for the laser-etched Sinotruk logo and batch number on the top flange to ensure you are receiving authentic HOWO parts.
