How to adjust the clutch height of Haval H6?
3 Answers
The method to adjust the clutch of Haval H6 is: loosen the adjustment nut on the pedal rod, adjust the length of the pedal rod, and then tighten it with the lock nut. The functions of the clutch are as follows: 1. Gradually increase the driving force of the car to ensure a smooth start; 2. Temporarily separate the engine and transmission for gear shifting; 3. Prevent overload of the transmission system; 4. Reduce torsional vibration impact from the engine and extend the service life of transmission gears; 5. Haval H6 is a compact SUV under Great Wall Motors, with body dimensions of 4615mm in length, 1860mm in width, 1720mm in height, and a wheelbase of 2680mm.
As an experienced mechanic, I've seen too many clutch adjustment failures. The Great Wall H6 uses a hydraulic clutch, where the focus is on adjusting the master cylinder push rod. First, loosen the push rod locknut, then use a 12mm wrench to turn the push rod counterclockwise to lower the pedal or clockwise to raise it. But after adjustment, you must get into the driver's seat to test: when fully depressed, you should be able to insert fingers into the gap between the pedal and the floor—about two fingers' width is normal. Remember to test drive after every 1/4 turn adjustment! Last week, a young guy raised it half a centimeter, causing the bite point to skyrocket, resulting in smoking clutch plates during hill starts. I recommend keeping a tape measure to check free play, with the standard value between 15-25mm. Too high makes shifting crisp but wears the release bearing; too low causes gear grinding. Final reminder: After touching the slave cylinder, you must pump the clutch pedal twenty times to bleed air, or else shifting will feel like poking cotton.
As a decade-long H6 manual transmission owner, my advice is don't rush into adjustments. The clutch pedal height directly affects the bite point position - incorrect adjustment can cause jerking at best or clutch burning at worst. Start by placing a water bottle between pedal and floor: with cold engine running in neutral, depress clutch steadily - bottle base should maintain half its diameter clearance from floor. If non-compliant, proceed with adjustment. I follow a two-step process: master cylinder pushrod adjusts total travel range, while a rubber stopper under driver seat controls free play. Hydraulic systems fear air most - after pushrod adjustment, have assistant pump clutch while you open bleed screw in engine bay until solid fluid stream appears. Always use genuine DOT4 brake fluid - last year's cheap aftermarket fluid caused pedal sponginess within three months.
