T-582C Internal Leslie

[Chasmac]

Hi - I think Brendan helped me with this issue last Fall when I first got this organ. When I first got the organ home and in my garage the temperature was in the 20's F and the internal Leslie would not turn at all. Yesterday I tried it again (it's trying to be Spring here in Minnesota USA, with temps in low '40's) and it has now started turning - at first the fast speed sounded like chorale, but eventually now the fast speed sounds as it should, but the slow speed sounds like it's stopped. Bendan, and other T-series owners, have you ever had a situation where the Leslie motor was affected this drastically by temperature change. Thanks - Charlie Mac

Hi Charlie!

There have been a lot of similar reports recently from the US with Standard Leslies and even Tone Generators!

It seems that the oil gets quite thick, even tacky in the cold.

My first thought is to try spraying the spindle the Drum spins on with something that'll get the thing eased up.... CRC, WD40 or something.

There are motor and belt adjustments we can look into later.

OH, does the slow motor spin with the belt removed? That'll let us know what state the oil in the slow motor is like....

Cheers!

Thanks Brendon - I'll get the WD40 fired up and ready to go. Will let you know how it goes. Charlie Mac

Ok, I'm halfway there - I did some lubricating and belt adjustments and now have a fast speed leslie that ramps up like it should. Still no slow speed though - Brendon, you said to see if the slow motor spins with the belt removed - I only see one motor there - are you asking me to take the belt off the motor and see if it spins on the slow setting? If there are two motors there I'm not seeing or understanding that. Thanks - Charlie Mac

The motors would be attached to each other, in a stack. One motor would be about 6 inches tall, and the slow motor would be about two inches tall. The big motor, at the opposite end of wear the belt that turns the rotor, would have another wheel with a rubber tire on it. The small motor, when engaged, would have a spindle that touches the tire to turn it. You only have a single speed?

I'll find a pic to fit Joe's description. Back soon!

Here we go:

The top one in this instance is in a metal box, but it's not on my other one. The top motor is actually smaller and gives the slow speed.

When it engages, a shaft in the motor rubs against a wheel with a rubber tyre, as Joe described. If you've got a two speed stack like this, this is where the problem might be: either the slow motor isn't going at all (maybe dead, or maybe a broken wire) or its notengaging the rubber tyre. The latter can be fixed by adjusting the bolts that attach the slow motor to the fast motor.

I'll post up a page from a manual shortly.

OR,

you can look in the T-500 manual here:

and there's a good pictorial breakdown in the leslie 122 manual here:

This looks like it fits the bill, If we have the right sort of two speed bill:

Thanks guys - I think I've got it now. The rubber tire thing is spinning on fast speed, but not on the slow setting, that I can see, so I can do some trouble shooting on that end. I'll let ya know. Charlie Mac

Did some more checking on this and have found that the slow motor spindle does not spin. Like you said, Brendon, could be a dead motor or a broken wire - any other troubleshooting I could try - the switch apears to be in order, but there must be a relay somewhere that could be broken?
