1, sealing weakened: the length and strength of the spring is designed to keep the oil seal tight to prevent oil leakage. Cutting the spring short will result in the spring not being able to provide enough pressure, thus weakening the sealing performance of the skeleton oil seal and further increasing the probability of oil leakage.

2. Spring failure: Cutting the spring short will cause the spring to become overstressed or deformed, losing its elasticity and eventually failing to return to its original state. This will result in the spring not being able to play a normal role in maintaining the tightness of the oil seal.

3. Damage to the rest of the components: When the spring is cut short, metal fragments or sharp edges will be produced, and these fragments will cause damage to the oil seal or the rest of the related components, further aggravating the problem of the oil seal.
