Should the Transmission Oil Seal Leakage Be Repaired?

[SavannahMarie]

Transmission oil seal leakage requires replacement if the leak is significant, while minor leaks can be repaired. Causes of leakage: Pipeline damage causes oil to leak from the damaged area during circulation; at the connection between the transmission and the engine, the sealing gasket may be damaged, or the fastening bolts may be loose, leading to an enlarged connection gap and reduced sealing effectiveness, resulting in oil leakage from the gap. Treatment methods: Improve the vent cap and inspection hole cover plate by opening an oil return groove inclined inward toward the machine at the center of the lower bearing seat, and also opening a notch at the straight edge of the end cover, aligning the notch with the oil return groove, allowing excess lubricating oil to flow back into the oil pool through the notch and oil return groove; improve the shaft seal structure by using new sealing materials; during transmission maintenance, strictly follow the process procedures, ensuring the oil seal is not installed backward, the lip is not damaged, the outer edge is not deformed, the spring does not fall off, the mating surface is thoroughly cleaned, the sealant is evenly applied, and the oil level does not exceed the oil dipstick mark.
