Lennox blower motor

I have a Lennox G40UH-48B-090-02 blower motor which sounds like it needs to replaced (Excessive noise and vibration).

It is mounted horizontally so that when I remove the front panels, the inlet and motor are on the right.

I have no idea how to remove this motor. I have loosened the screws to the electronics panel so I can slide that off the screws and hangs loose. I can see inside that the motor seems to be on rails. As the installation is horizontal, one rail is above the other.

The only screws I can see which might hold it in place are so inaccessible that it seems improbable. If I can get them out...getting them back in with the new motor may be a different issue.

I have checked to see if there are other panels which can be removed but there aren't.

I saw one video where two retaining screws towards the front held the rails in place but I have no such screws.

Anyone have some tips ?

Thanks in advance.

Some pictures of the blower & blower compartment might help us help you with removal.

I would expect to remove the red screw on each side of the control box to gain access to the blower and then remove 2 screws highlighted yellow to slide out the blower if you have the furnace in this picture...

Once you get the control panel out of the way, blower removal should be easy.

Usually you need a socket set to remove the screws.
