excavator seal

What should I do if the excavator seal leaks oil? More than 90% of the oil leakage problems are because the rubber excavator seal has been subjected to alternating cold and warm temperatures for a long time, resulting in the loss of a large amount of plasticizers and softeners in the sealing ring, and the problem of corrosion, aging and hardening occurs. The phenomenon of oil dripping started slowly, and the sealing ring broke after a long time. In the past, the oil leakage was solved by dismantling the engine and replacing the oil seal. Now with the development of technology, the leakage can also be solved by not disassembling and repairing. oil problem.
