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.

This particual gear assemgly will work on many different brands of openers, it the unit is full chain and has a T style rail, there is a very good possiblity this assembly will work for you. Of all of the gear type assemblies currently in productioon, this is the most robust and has the most cross over potential of any.

This is not for CHAIN / CABLE MODELS, We do carry that pulley and the pulley assembly, see the below links

We like to keep older machines in use as much as possible.
