Common Failures of CHERY F4J16BJ1004120 Piston ring for TIGGO8 PRO PHEV/TIGGO8 PRO/TIGGO8/TIGGO7/TIGGO7 PRO
- Excessive Oil Consumption: In TIGGO series including TIGGO8 PRO PHEV, the piston ring (OE: F4J16BJ1004120) may wear out, leading to oil seeping into the combustion chamber.
- Loss of Compression: A common issue in TIGGO models. When the piston ring fails, it can't seal properly, causing a drop in engine compression.
Maintenance Tips of CHERY F4J16BJ1004120 Piston ring for TIGGO8 PRO PHEV/TIGGO8 PRO/TIGGO8/TIGGO7/TIGGO7 PRO
- First, before installing the CHERY piston ring (OE# F4J16BJ1004120), ensure the piston and cylinder wall are clean and free of debris. This helps prevent premature wear.
- Second, use a piston ring expander when fitting the piston ring onto the piston in TIGGO8 PRO PHEV, TIGGO8 PRO, TIGGO8, TIGGO7, or TIGGO7 PRO models. Do it gently to avoid breaking the ring.
- Third, check the end gap of the piston ring. It should meet the manufacturer's specifications. Incorrect end gap can lead to poor engine performance.
- Fourth, lubricate the piston ring with engine oil before installation. This reduces friction during the initial startup of the engine.
- Fifth, install the piston rings in the correct order as marked. The top ring is usually different from the bottom ones for optimal sealing.
Caution! Do not over - expand the CHERY piston ring (OE# F4J16BJ1004120) during installation. Excessive expansion can cause the ring to crack and lead to engine failure.
