Car knowledge sharing: How to adjust the clutch cable, pay attention to the following points.

The clutch is the connecting component between the engine and the transmission. The action of the clutch directly affects the shifting of the transmission, so the clutch needs regular maintenance and adjustment. During use, the clutch should be checked regularly to see if it needs to be replaced. If a component of the transmission fails, it should be repaired promptly. The main content includes: adjusting the shape of the clutch (separating clutch) according to your vehicle model; determining the transmission ratio, engagement clearance, and adjustment method based on the actual driving conditions of the car and the wear condition inside the transmission.

1. When repairing the car, first fix the clutch pressure plate (i.e., the semi-clutch mechanism) to the car chassis, and step on it with your foot to ensure that the clutch spring rod contacts the shaft hole with appropriate tightness.

When the tension (i.e., axial force) of the clutch pressure plate spring rod is released, the clutch pressure plate contacts the shaft hole. At this time, the cam on the clutch pressure plate also moves to the center of the shaft hole, with an angle of about 90°. Then gently press it with your hand to align it with the shaft hole without loosening. Then push the clutch mechanism by hand to ensure that the clutch pressure plate fits well with the hub bearing surface and the bearing clearance is appropriate. Ensure that the clearance between the shaft hole and the car's pin hole is the same, and then install the shaft pressure plate onto the car's bearing. Tighten the axial force bolts to fit the half shaft with the shaft, allowing the lubricating oil in the bearing seat to flow through the clutch pressure plate and the semi-clutch mechanism shaft hole. Finally, remove it from the car chassis, and tighten the lock nut to the clutch pressure plate and the fixed shaft (during maintenance, tighten the above bolts). After installation, tighten the pressure plate nut and the shaft hole bolts; then measure the thread hole diameter of the bearing seat. If the cam clearance of a certain shaft hole after vehicle repair still does not meet the requirements, adjustments are needed: use manual tools to adjust the gap between the transmission pressure plate (pressure plate) and the shaft hole to the specified size. If neither of the above two methods works, the gap between the pressure plate pin hole and the shaft hole can be adjusted appropriately to fit perfectly. However, during assembly, care should be taken to ensure that the clutch pressure plate does not wear out prematurely when the vehicle starts smoothly; conversely, this should be avoided. It can also cause gear rotation vibrations, leading to mechanical accidents such as clutch friction plate breakage and wear. This requires automotive maintenance personnel to check and adjust according to the actual situation and operating conditions of the vehicle. The specific method is: before car maintenance, the clutch pressure plate should be cleaned to remove carbon deposits, rust, and other foreign objects; check whether its engagement clearance meets the requirements. If not, it needs to be repaired or replaced with a new semi-clutch mechanism. The engine, transmission assembly, and transmission components must be placed in a non-vibrating state; adjustments should be made when the wear of each component allows; adjustment method: please have technical personnel make the adjustments.

2. After starting the engine, first pull the clutch pull rod to the highest point of the pressure plate mating surface, and then immediately step on the clutch pedal to check whether the eccentricity is normal.

If the eccentricity exceeds 60%, the pressure plate gap can be adjusted until it meets the requirements. When replacing the clutch pull rod, first pull out the head of the pressure plate bolt, and then manually tighten the contact area of the bolt with the pressure plate mating surface. When the eccentricity exceeds 70%, adjustments should be made. If there are friction marks on the pressure plate, it indicates that the pressure plate gap is too large or not fitting, at which point the clutch pull rod should be replaced; otherwise, the shaft pin should be adjusted. When it reaches over 70%, the transmission lining must be replaced to ensure the correct transmission ratio of the transmission. However, it should be noted that if the new gear cannot be put into normal operation immediately, it must be shifted before adding fuel to start the engine. Since the automatic transmission does not respond to the engine, after starting the engine, the clutch pedal should be gently lifted while idling, and then lifted again. This ensures that the clutch works normally, the engine starts smoothly, and the clutch does not make abnormal noises; it also allows the rotor of the engine's high-speed rotating part to generate a strong impulse, avoiding accelerated clutch wear!

3. Place one end of the clutch disc on the pressure plate or in the groove of the installed pressure gauge.

Use an oil gauge to measure the distance between the center line of the pressure plate and the flange to be 1.5-2.0mm. Fix the pressure plate to the flange, and the minimum flange surface of the clutch end pressure plate must be parallel to the flange; otherwise, it will greatly damage the pressure gauge, which should be replaced. Place the adjustment handle in the P position to make the flange on the pressure plate parallel and press it into the groove. Then adjust the gap of gears 1-2 so that the clutch disc sinks about 1.5-2mm.

4. When the angle between the top surface of the pressure plate and the pressure wheel shaft is less than 90 degrees, the cam cover cam should press against the cam bearing body.

When the angle between the top surface of the pressure plate and the pressure wheel shaft is less than 90 degrees, the cam height is the height of the clutch, assuming the cam presses against the cam bearing body. The clutch pedal is generally placed flat, and after stepping on the clutch pedal, the area that needs adjustment is the clutch engagement clearance. The car can only shift gears when the clutch is in neutral, and the clutch must be fully pressed down when shifting; otherwise, it may cause serious damage to the transmission or pose a safety hazard while driving. Therefore, it is very necessary to regularly check the clutch. We can also treat the automatic transmission as a machine for better driving experience. Automatic cars generally use CVT or AT transmissions for driving, so how can we ensure that the transmission and clutch fit closely?

5. During the adjustment process, the non-reverse tooth correction method should be used.

First, during the transition from P gear to no-load acceleration and deceleration, the height and speed of the pressed clutch pedal must meet the requirements. Then, before shifting gears, press down the clutch pedal and let the car slowly drive on a surface that does not reverse the fork or teeth. Then stop and let the engine run for 5-10 minutes to check whether the clutch pedal is fully pressed down. If you feel that the clutch pedal is pressed down but does not immediately engage, then the clutch has a fault. If the vehicle is moving very slowly, it cannot guarantee that it will not stall; if it still does not stall, it indicates that the clutch cannot smoothly separate. Generally, we cannot completely avoid such faults. Because it is possible that our car's clutch needs timely repair or replacement after a fault occurs, otherwise it will affect the lifespan of our car. This is something we should pay attention to.

6. Adjustments should be made every 3000 kilometers or so. First, shift the gear lever into gear, slowly drive the car for a few minutes to 1-2 minutes, and then turn on the ignition switch (start the engine). At this time, if the reverse gear cannot still be engaged, the required gear cannot be engaged.

If the reverse gear still cannot lift the upshift limit, the clutch needs to be readjusted. At this time, the vehicle should be stopped in place, waiting for the gear lever or other normal operations. During use, the clutch mechanism may experience fatigue, local overheating, and loosening of internal metal parts due to wear of the friction plate, camshaft, and friction plate surface, which can cause clutch engagement and, in severe cases, lead to engine failure. Therefore, regular maintenance and adjustment should be noted when using the clutch.
