You have to order the whole part just to get the gear, you can't buy the gear separately. Then just swap the gear.

I do have the whole assembly. I know what's broke on it- it's the idea of swapping the old with the new- is it really a 10min job? Looked a lot more complicated than that

[Matt]

Swapping the gear is a 10 minute job. Swapping the whole assembly is not.

I would say you should contact with a HVAC contractor to check the issue.
