That RT-3 looks nice!

By the way I still haven't moved the RT-2. First I got cancer, then I got lazy. It's still in my friends's garage waiting for me.

I'm real close to retiring, so after that I'll have a lot more time for a restoration project like this.

It only took me 3 YEARS to get this thing into my basement, but here it is! That freaking thing weighs a TON!

My new (old?) Hammond RT-2 organ. Its got a full set of bass pedals in a arc not installed in the pic. This organ hasn't been started in probably 15 years and it's been in a garage that long too, so any words of wisdom would be helpful.

I was going to order some fresh hammond oil. But how much to put in the tin cups? I turned the tonewheel generator main shaft and it feels like it's turning.

Hammond RT-2 finally moved into my basement!

Here's the speaker cab. It's got 11 speakers in it plus a oil filled reverb unit.

3 or 4 drops of oil in the cups is a good start. Never fill them all the way up or you'll have oil everywhere. There should be some thread-like filaments connected to some of the cups. As long as they are oily you have enough oil in the cups.

If something in the tone generator or chorus generator is bound up, oil it up and let it sit for a week or two then try to start it again. If it still doesn't work check the filaments to see if they are still oily. If not put a few more drops in the cups and let it sit for a few more weeks. That will usually fix things but occasionally something has to be disassembled and freed up. I had a locked up chorus generator on my old M3 that I had to remove and clean up to get it working. Most of the time that's not necessary. It just depends on the environmental factors where the organ has been stored.

Well, this thing has got some issues.

A few days after oiling I was able to get the tone generator to start up and run, but after about 5 minutes it stalls out. So it works - I'm hopeful after a few weeks it will loosen up more.

It feels like the tone generator has low friction but the scanner feels gummed up. If things don't loosen up more I'm going to have to remove the scanner and clean that out.

HR-40 tone cabinet - all the speakers work but the power amp has a horrible hum and I don't think the old reverb is working. I removed the reverb and old tube amp. I'm planning to install a modern power amp instead.

Pedal solo unit - It's not working so that got removed also. The bass pedals work fine with the tone generator, except for the higest pedal - that switch is frozen.

The manuals, drawbars, and tablet switches work OK but they need cleaning.

Another update:

I removed the synchronous motor / scanner. It turns out the scanner is not dragging, it's the synchronous motor. After a couple days with penetrating oil, then hammond oil I reassembled it. It ran about 10 minutes then stalled out again with high motor friction.

I'll probably be replacing the synchronous motor if I can find an exact replacement. Everything else (scanner and tone generator) turns freely.

Today I replaced the synchronous run motor and now the organ will reliably start and run. Here's a short video showing some of the restoration work I have done so far.
