1, Fault Failure Performance (Damaged Rotating Seat)

The valve does not rotate → single-sided erosion, conical pitting, and air leakage of the exhaust valve

Insufficient cylinder compression pressure, difficulty in cold starting, and idle shaking

High exhaust temperature, continuous black smoke emission, decreased power, increased fuel consumption

In severe cases, the valve head may melt or break, causing the piston and push rod to bend

Disassembly reveals pitting, jamming, and fragmentation of the rotating seat raceway, resulting in loss of rotational function

2, Key points for major repair and installation

When overhauling the cylinder head, it is necessary to replace the entire set. Mixing old and new may cause asynchronous rotation and rapid wear of the valves

Installation sequence (from bottom to top): Valve spring lower seat → Inner and outer valve springs → 3065936 rotating seat → Spring upper seat → Valve lock plate
