Common Failures of BYD 1307215500 Connecting Rod Bearing for Qin PLUS DM-i/Song PLUS DM-i/Song PRO DM-i/KING DM-i/Chazor DM-i/Seal5 DM-i/Destroyer 05 DM-i
- Bearing Wear: Common in Qin PLUS DM-i and other models with OE number 1307215500, caused by long - term high - load operation.
- Oil Film Breakdown: May occur in Song PLUS DM - i, resulting from poor lubrication and leading to abnormal noise.
- Overheating Damage: Seen in Chazor DM - i, often due to excessive friction and lack of heat dissipation.
Maintenance Tips of BYD 1307215500 Connecting Rod Bearing for Qin PLUS DM-i/Song PLUS DM-i/Song PRO DM-i/KING DM-i/Chazor DM-i/Seal5 DM-i/Destroyer 05 DM-i
- First, ensure the connecting rod bearing (OE# 1307215500) is suitable for BYD models like Qin PLUS DM - i, Song PLUS DM - i, etc. Clean the connecting rod and crankshaft journals thoroughly before installation to prevent debris damage.
- Next, check the bearing for any signs of wear or damage. A damaged bearing can lead to poor engine performance. Use a micrometer to measure the bearing's inner diameter and compare it with the specifications for BYD engines.
- Then, apply a thin layer of engine oil on the bearing surface. This helps in smooth installation and reduces friction during the initial engine startup. Make sure the bearing is correctly positioned in the connecting rod.
- After that, tighten the connecting rod bolts to the specified torque. Incorrect torque can cause bearing misalignment and premature wear. Refer to the BYD service manual for the exact torque values.
- Finally, reassemble the engine carefully, double - checking all connections. The quality of the connecting rod bearing affects the overall reliability of BYD DM - i engines.
Warning: Do not over - tighten the connecting rod bolts when installing the connecting rod bearing (OE# 1307215500). Over - tightening can cause bearing deformation and engine damage.
