What Causes Vehicle Shaking When Starting in First Gear?
1 Answers
Shaking or jerking sensations when starting in first gear may be caused by poor clutch lining contact, weakened damping spring tension, or uneven pressure spring tension in the clutch. Below are detailed explanations of the causes and solutions: Weakened Damping Spring Tension: Reduced elasticity in the clutch torsional damping springs can cause shaking during clutch engagement. If this is confirmed as the issue, the springs should be replaced promptly. Poor Clutch Lining Contact: Hardened clutch lining surfaces or adhesive deposits can easily lead to clutch shaking. Any foreign substances on the clutch lining should be removed immediately. Uneven Pressure Spring Tension: Inconsistent tension among the pressure springs, misaligned release lever adjustments, or uneven diaphragm spring fingers can result in asynchronous engagement timing. This causes uneven force distribution on the pressure plate, potentially tilting it and leading to poor contact between the driving and driven plates, resulting in clutch vibration. In such cases, it's advisable to visit a repair shop for inspection and replacement.
