How to Adjust Belt Misalignment?
3 Answers
If the car's belt is misaligned, adjustments should be made from the head of the machine when the vehicle is running unloaded. First, adjust the empty section, then adjust the loaded section. Belt misalignment should also be adjusted based on the position of the misalignment. If the belt is misaligned in the middle of the conveyor, observe which direction the belt is running, and the idler should be moved forward in the direction of the belt's movement, adjusting according to the belt's operation. If the belt is misaligned on each roller, observe the direction of the belt's misalignment and use the adjustment bolts on the roller shaft seat to adjust the direction of the belt's misalignment. The car's drive roller, nose roller, and tail roller have already been adjusted when the car left the factory, and they are not easily readjusted under normal circumstances.
When I first noticed the belt misalignment as an ordinary car owner, I panicked. But after checking some materials, I realized I needed to adjust it myself. Remember to park the car in a safe place first, turn off the engine and let it cool for at least half an hour - protecting yourself is the top priority. The first step is to check if the belt is loose or has wear cracks. If it's loose, locate the tensioner pulley's fixing bolt, loosen it slightly with a wrench, then manually adjust the pulley's position to align the belt with the track, and finally tighten the bolt. Over-tightening will accelerate wear - you can test the elasticity by gently pressing the middle of the belt with your finger. If the belt is already torn or severely aged, don't force adjustments - it's more cost-effective to replace it at a repair shop. For prevention, check the belt's condition monthly. Wet roads during rainy days can also easily cause slipping and misalignment, so pay extra attention to engine noises before driving.
I have years of experience dealing with belt misalignment, with common causes being rusted pulleys or improper installation. Before adjustment, prepare wrenches, a torque wrench, and a flashlight. First, check if all pulleys rotate smoothly without wobble. The tensioner pulley is often the key point—loosen the bolts, manually adjust its position to align with the belt track, ensuring moderate tension—neither too tight nor too loose. Tighten with a wrench and start the engine for testing. If the pulley is deeply worn, replace it directly to avoid recurring issues. Make it a habit to inspect belt wear every 5,000 kilometers—a snapped belt at high speeds is extremely dangerous. Proper maintenance can save you from costly repairs.
