- Oil Leakage: In many BYD models like Han EV and Tang EV with OE number 1224949400, the transmission oil seal often causes oil leakage, which can lead to insufficient lubrication.
- Seal Aging: Over time, the transmission oil seal in Atto3 PRO EV and other models may age, losing its elasticity and resulting in poor sealing performance.
Maintenance Tips of BYD 1224949400 Transmission oil seal for Han EV/Tang EV/Atto3 PRO EV/Yuan PRO EV/Dolphin EV/Qin PLUS DM-i/Song PLUS DM-i/Song PRO DM-i/D1 EV/KING DM-i/Chazor DM-i/Seal5 DM-i/Destroyer 05 DM-i/DENZA D9 DM-i/DENZA D9 PHEV/DENZA D9 Hybrid
- Firstly, before replacing the BYD transmission oil seal (OE# 1224949400), drain the transmission fluid properly to prevent spills. This applies to models like Han EV and Tang EV.
- Secondly, clean the mating surfaces thoroughly. Any debris or old seal material can cause leaks, so ensure a smooth installation surface for all BYD models including Atto3 PRO EV and Yuan PRO EV.
- Thirdly, use a suitable seal installer to press the new transmission oil seal evenly. This helps to avoid damage and ensures a proper fit in models such as Dolphin EV and Qin PLUS DM - i.
- Fourthly, check the seal lip for any damage before installation. A damaged lip can lead to oil leakage, which is crucial for BYD's Song PLUS DM - i and Song PRO DM - i.
- Lastly, refill the transmission fluid to the correct level after installing the new seal. This step is important for all BYD vehicles like D1 EV and KING DM - i.
Caution! Ensure the transmission is cool before replacing the BYD transmission oil seal (OE# 1224949400) to avoid burns from hot transmission fluid.
