Re: Old Motors
 

Because the gear that is on that motor does not fit what we have

Re: Old Motors
 

Well, what do you have?

Re: Old Motors
 

What can it get attatched to?

Re: Old Motors
 

The gear we are attaching is about 5.25" diameter with 64 teeth

Re: Old Motors
 

By "gear", do you mean the 6-pointed star looking thing on the denso?

Or by "gear", do you mean a 64 tooth chain sprocket?

Or by "gear", do you really mean "gear"?

How did you possibly get a 64 tooth "gear" to fit perfectly on one of the old keyang motors, but not a window motor?

Re: Old Motors
 

There were 4 compatible couplings in the kit of parts that can be mated to keyed shaft or bolted onto something. Either method could be used to mount you gear, but you should choose the one that works the best.
