Many times when a pulley fails, the bolt and or spud can be damaged or out of alignment, it is usually prudent to replace the entire bracket and pulley assembly. Cost is negligible and if the bolt, shaft, spud is not correct, another pulley failure will be the result. There are not many things that con go wrong with this type of garage door opener, keeping the drive system, the chain, chain / cable or belt assembly and pulley in good working order will prevent the majority of issues you can have. We will typically replace the entire assembly, this entire kit, we do not want our customers to have any further issues. With a belt, it is very likely that the belt was damaged if this pulley failed or was in the process of failing.
