Why is the vent hole on the transmission constantly leaking air?
1 Answers
The function of the vent hole is to ventilate the transmission. When the transmission runs for a long time, it heats up, causing the oil inside to expand and increase internal pressure. Without a vent hole, the oil could damage the oil seal, leading to air leakage. Precautions for use are as follows: 1. Prevent the loss of the vent hole cover. If the cover is lost, it is easy for dust, impurities, moisture, etc., to enter the transmission and mix with the oil, causing transmission failure. 2. Keep the vent hole unobstructed. Do not block the vent hole, as blockage may cause oil leakage in the transmission. 3. When passing through waterlogged sections, be careful to prevent deep water from submerging the transmission vent hole, which would allow dirty water to enter the transmission. This can lead to internal rust, increased wear, abnormal noise, and damage to the transmission.
