Reasons for Severe Shaking at the Moment of Starting with Newly Replaced Clutch Three-Piece Set
3 Answers
Replacing the clutch disc may cause shaking during start-up. Since the new clutch has machining marks, it requires mutual running-in to become smooth. The shaking phenomenon will disappear with increased usage time. Reasons for car shaking during start-up: Wear in the three clutch components (clutch disc, flywheel, pressure plate), usually significant wear in the clutch disc, leading to shaking during start-up. Too little throttle during start-up, resulting in too low engine output power, causing the vehicle to shake during start-up. Solutions for car shaking during start-up: Poor contact of the clutch lining, surface hardening, or adhesion of sticky substances can easily cause clutch shaking. In this case, the clutch lining should be reconnected.
I noticed that the newly replaced clutch kit has significant shaking during the initial take-off, usually due to improper installation, such as an uneven flywheel surface or overly tightened screws causing uneven pressure distribution. Additionally, this phenomenon can occur when new components haven't been properly broken in—it typically improves after driving a few hundred kilometers, but avoid aggressively stepping on the accelerator. If the shaking persists, it might indicate poor alignment between the clutch disc and pressure plate, requiring rework to check flatness and clearance. Also, inspect whether the release bearing is sticking, as these issues can lead to unstable starts. For routine maintenance, it's advisable to regularly lubricate related components and avoid interference from residual old parts—safety always comes first.
I think your issue is quite common. I also experienced severe body shaking when starting after replacing the clutch. It's mainly because new parts need a break-in period. The friction disc and pressure plate aren't smooth yet when first installed, making the clutch prone to shudder during engagement. Try releasing the clutch pedal more gently when starting. Another possibility is poor installation - loose bolts or misalignment can cause uneven pressure and vibration. Don't underestimate this issue, experienced drivers know it affects vehicle lifespan. My habit is to do a short break-in run first. If shaking persists, go to the repair shop immediately for recheck to avoid accidents.
