Why do my timing belt keep coming off?
The belt can break due to a number of reasons, but the most common is age. If the tensioner is bad, it can cause the belt to come loose or cause the pulley to seize, making the belt come off. Knowing some of the signs of a bad belt tensioner can help you to prevent serious engine damage due to a timing belt failure.
Can you tighten a timing belt too tight?
If the timing belt is insufficiently tense, there is a danger that it will ping off. If it is too tight, all of the bearings will be stressed, which is definitely also a bad thing. In the worst-case scenario, the belt can even snap.
What keeps the belt tight?
The tension in the serpentine belt keeps it tight and straight on the connecting pulleys and prevents it from flipping over.
What happens if your timing belt is too loose?
Proper tensioning cannot be stressed enough: too loose of tensioning will cause the timing belt to ratchet (tooth jumping), while too tight of tensioning will possibly cause damage to the bearings, shafts and other drive components besides dramatically reducing timing belt life.
Can a taut timing belt stand a strong pull?
While a taut string or timing belt can stand a strong pull. Take up any loose slack in the timing belt by adjusting the center to center distance between the two timing belt pulleys. Before any final tensioning is to be applied make sure that the timing belt teeth are fully seated in the tooth grooves on both timing belt pulleys.
Can a crank pulley be removed from a timing belt?
The crank pulley is the main pulley at the bottom of the engine. It needs to be removed in order to change the timing belt. However, it’s not easy if you only have hand tools, since the torque on this bolt is often pretty extreme.
Where do you place the timing belt on a timing belt?
Do not pry the timing belt onto the timing belt pulleys. Place the timing belt on each timing belt pulley and ensure proper engagement between the timing belt pulley and timing belt teeth. Lengthen the center distance or adjust the tensioning idler to remove any timing belt slack.
