Hi I have a Leslie 46 W with 2 motors fast and slow, </p>
Sometimes after I fire it up it doesn't really spin fast in the fast tremelo setting.</p>
meaning it's speeds up a little, about "half speed" then usually after ten minutes it begans to spin normally.... using through a leslie preamp. Any suggestions on possible adjustment or repair?</p>
You don't mention which rotor but if it's the horn, then take it off and wipe the bushing inside the horn and outside the spindle with WD40 or something to clean the old oil off. Then reoil with Hammond oil. The old oil has probably become gummy.
Hammonds: A; AB; B3; D; E; 6-M3's; 2-A100; T582C.
Leslies: 3-31H; 21H, 22H, 4-44W; 46W; 25; 47; 45; 125; 50C; 51; 55C; 2-120; 122; 122A; 145; 147; 245; 770; 825; 2-102; 2-103; 300.
Wicks 2/5 pipe organ; Yamaha upright; Kurzweil Micro Piano & Micro B with M-Audio Oxygen 61; Yamaha DGX520; Wurlitzer 4100 (it came with a Leslie!). Peavey KB100 keyboard amp. Peavey Bass Guitar. Yes, I have A. D. (acquisition disorder) and don't want it cured.
The horn on one of my 760's used to do this. When I first turned it on and also if I left it on chorale speed for a while. It would take 5 or 10 minutes to kick into full tremolo. Once there, I could switch back and forth no problems. Leave it on chorale for 5 or 10 minutes it try tremolo again and I was waiting.</p>
I took the upper motor apart according to the service manual instructions to clean and oil the bearings. I opened the motor up but I did not find any bearings so I just oiled the 2 felt pads and put it back together.</p>
It now does this only when i first turn the organ on. I go over to it cursing under my breath (okay, sometimes right out loud...) and push in on the idler pulley (taking tension off the motor pulley and horn) so the belt goes a little slack and I can hear the motor ramp up to full speed. Only difference now is I can leave it on chorale for hours and when I switch to tremolo - no problems. Only when I first turn it on.</p>
I suspect i almost got whatever was wrong fixed - but not quite. But then again I was always good at suspectin'. I guess it may qualify as half-assed fixed. I will fix it all the way someday. Maybe the belt...maybe the horn bearing, maybe the idler pulley...
</p>
Good luck. I know how it sucks to have a stinky tremolo (or I used to).</p>
The bearings are the bronze parts in the middle of the end bells on the motor. Those need to be cleaned as well as the armature shaft (the part that actually rotates in the motor).
In my experience the motor is not *usually* the problem. yes, they do need TLC because of their age and typical lack of maintenance, but I find the if you remove the belt and change speeds, 90% of the time the motor speeds up instantly. Make sure the idler pully isn't gummed up. But the next best bet is cleaning the horn bearing and spindle place as admiral indicates.

[:^)] I was expecting dozens of little steel balls to go bouncing all over the kitchen as I carefully opened up the motor...</p>
Stick two drops of oil down the oil hole in the horn. The oil hole is accessed by removing the upper cabinet cover and looking at the base of the horn above the bearing/bushing area. It should say "OIL HERE" or something like that in white letters.</P>
Motor service can be simplified by using a pinpiont oiler and hitting the motor bushings/bearing directly. Leslies are not picky about oil. The sewing machine stuff will work fine as will fishing reel oil or Hammond oil too.</P>
And here I thought I was the only guy that is punished by his Leslie =)</p>
I've been turning the thing off and on a few times to let the pully bounce around a little. I usually turn it off/on in 3 second increments and it usually gets going around the 7th time. </p>
Never thought of cleaning or oiling though! May try that today. I had figured it was a belt that was maybe slipping at first until the heat caused a little friction....</p>
Has anyone tried changing the speed-selector shaft with larger pullys?</p>
I'll will just say that I prefer Hammond oil. I don't care for the thicker Leslie oil. Hammond oil seems to really get things moving, probably because of the thinner consistency.</p>

I like to set the belt on the smallest pulley. The other pulleys cause the horn to spin way too fast. It creates almost a theatre organ sound.
