SINOTRUK D12,WD615 ENGINE Rear Engine Mount / Engine Rear Support Rubber Pad WG9725592131
It is installed between the chassis frame and the flywheel housing brackets located on both sides of the rear of the engine (near the transmission connection). Given the immense weight and massive explosive torque characteristic of heavy-duty truck engines, this rubber mount-utilizing a steel plate and a specialized structural design-firmly supports the engine's weight. It also absorbs high-frequency engine vibrations and road-induced shocks during operation, thereby preventing vehicle body resonance.
Inspection Intervals
Routine Inspection: Every 10,000 km driven or every 300 operating hours (inspect visually using a flashlight during chassis lubrication and maintenance).
In-depth Tightening: For new vehicles or after a major overhaul involving gasket replacement, the long central bolt must be retightened using a torque wrench after the initial 1,500 km of operation.
