Hello all,
I have a Genie Model PCG650 - Chainglide garage door opener that apparently the previous owner took apart the Power Head Assembly, so I’m not sure if it works or not.
I’m looking at the following motor parts, long metal piece that’s mostly square but round on one end, and has a round washer clamped on to it. I can tell it cranks the motor, but I’m not sure which end goes into the assembly on the ceiling and which end goes into the assembly in removed cover.
I also have a round washer and what appears to be similar to washer but it’s not flat. It’s square on one side and round on the other side, which extends outward. I’m not sure where these go or if they’re needed.
Any guidance here would be greatly appreciated.
