What are the reasons for the failure of the clutch pump in the Baojun 730?
2 Answers
The following are the related causes and symptoms of a faulty clutch pump in the Baojun: 1. Reasons for the failure of the clutch master pump: The clutch master pump may fail due to improper operation by the driver, poor quality of the pump body, damage to internal rubber seals, or insufficient clutch fluid leading to the damage of the clutch master pump. 2. Symptoms of a faulty clutch master pump: A faulty clutch master pump may exhibit oil leakage. The most obvious symptom is difficulty in shifting to the desired gear after pressing the clutch, or even inability to engage any gear, as the master pump failure can cause incomplete or no separation of the clutch.
I encountered a clutch pump issue while driving the Baojun 730, where the clutch pedal felt unusually stiff or unresponsive, which was quite troublesome. There could be several reasons: first, the sealing ring inside the clutch pump may have aged, leading to oil leakage over time and resulting in insufficient hydraulic system pressure; second, the hydraulic oil might be too dirty or deteriorated, causing the pump to jam and the oil passages to clog; third, improper driving habits, such as frequent half-clutch use or aggressive acceleration while operating the clutch, can accelerate pump wear; fourth, prolonged vehicle use without maintenance may introduce air into the oil cylinder or allow dust accumulation. In such cases, I should promptly check the oil level and color, and replace the seals if there's leakage. For daily maintenance, it's advisable to change the hydraulic oil every two years and operate the clutch gently while driving. Delaying repairs could lead to further damage to the clutch disc, affecting the entire gear-shifting system and compromising driving safety.
