Leslie cabinet. Minor repair question?

My 3 year old son messed with my leslie one day.

There is a little band that connects the horn to a pully that goes down to the low rotor. Basically, my kid pulled this band loose.

Now, I can't quite figure out how to get it to go back on. There is a little tension mechanism in there that I don't quite know what to do with.

Any help would be appreciated. It looks like a really minor fix, but I don't want to mess any thing up.

Thanks so much!

ITs no big deal - you can access the rotor pulley by pulling the 15" speaker (coupla screws).

Well, He said the horn but also he said lower rotor. I can't imagine a 3 year old being tall enough to reach the horn belt. He must mean the lower rotor.


This would be a great time to replace the belt. It is also the perfect time to replace the rotor upper and lower bearing rubber bushings.They're availalble at Tonewheel general hospital.

Pull the back cover off. Disconnect and remove the speaker wires. Remove the speaker. At that point you will be left with the bearing bracket which contains the rotor shaft and pulley which is let into a couple of notches in the speaker platform. You do not need to remove the shaft assembly if you're only reattaching the belt or installing a new one. You will see the old belt if it didn't break. Just slip it around the shaft pully on one end and the motor pulley at the underside of the speaker platform at the other. You will also see a simple adjusting mechanism in the shape of an eliptical slot with a adjusting wing nut on the motor bracket.

The belt tension is important. You will need enough tension initially to keep the belt in position without causing the bearing bracket to come out of the slots (the bearing/shaft bracket is held in place by the speaker screws). Reinstall the speaker. Start the leslie with the back still off. There should be some belt slippage as the rotor reaches fast speed. The amount really depends on rather it is a wooden rotor or foam. When switched to fast speed, it should take about 5 seconds for the lower rotor to reach full speed when the belt is at the proper tension. So you would adjust the motor bracket slot via the wing nut to acheive the correct belt tension. When you are satisfied with the rotor spin up speed, reassemble the back.

If you decide to replace the rubber bushings, you will need to pull the shaft for the top bracket. The bottom bushing in the bracket underneath the Leslie is reached by laying it on it's side.

Thanks so much Danny,

It is actualy the upper belt that came off. My son was standing in a chair!

It really looks like such a simple fix, but I just don't know where the tension mechanism goes.

Could anyone post a picture of the upper belt/horn assembly? I see them in lots of shots, but they aren't big enough. If I just had a pic, I could fix it in seconds.

Thanks!
