The steps to remove and install the generator belt of Refine S7 are as follows: 1. Lift the vehicle and remove the right front wheel fender liner; 2. Remove the generator belt and the generator belt tensioner; 3. Loosen the crankshaft pulley screw; 4. Open the engine hood and remove the water tank; 5. Remove the protective cover on the engine mounting bracket belt; 6. Unscrew the generator fixing screw and take out the generator; 7. Remove the cylinder block fixing bracket and take out the crankshaft pulley; 8. Rotate the crankshaft to the top dead center position of the cylinder and make a mark; 9. Remove the old belt, replace it with a new one, and then install it in order. The generator belt is an important part of the engine valve system. It ensures the accuracy of intake and exhaust timing by connecting to the crankshaft and matching a certain transmission ratio. The upper part is connected to the timing wheel of the engine cylinder head, and the lower part is connected to the crankshaft timing wheel.
As an experienced driver, I'm very familiar with removing and installing the alternator belt on a JAC Refine S7. First, prepare a 14mm wrench and open the engine hood to locate the belt tensioner. Use the wrench to press the tensioner bolt counterclockwise to loosen the belt, then you can remove the old belt from the alternator pulley and crankshaft pulley. When installing the new belt, pay special attention to the routing path - it's best to take photos beforehand for reference. Align the belt with the pulley grooves and slowly fit it on, then release the tensioner to let the spring automatically tighten the belt. Checking belt tension is crucial - press the midpoint of both old and new belts to compare elasticity; the deflection shouldn't exceed half a finger's width. After installation, start the engine to listen for abnormal noises, and recheck the tightness after a few days of driving. DIY saves labor costs, but inexperienced folks should ask a friend for help to avoid stripping the bolts.
