No Giant here, but may have had a similar experience.... Here's some basic information that may help you start down that road. I supply this very late at night, tired and stupid, but it's an informational starting point to consider. Your Mileage May Vary. Professional Driver on a Close Course. Don't try this without adult supervision.

If the start motor is "chugging away" but the main shaft is not moving, you probably have the shaft coupling gear not engaging with the start motor gear. The oil gets old and that shaft gear is spring loaded to give way while the starter gear engages with it. If it is stuck in the "give way" position (mine was) then letting the start motor run in this instance will bugger up the teeth eventually and get you nowhere.

Try turning the main TG shaft via the coupler disc just to the right of the Run Motor to make sure that it is free.

I don't recommend this for you, because you can't blame me if you are electrocuted or break an oil thread or do other damage, but I actually took my right index finger and pushed on the start motor shaft to help it engage with the shaft gear and held it in while the start motor brought the TG up to speed. Once running, everything else was fine. I did this every time that I wanted to play for a couple of weeks.

This worked, but was very inconvenient. I tried a variety of spray solvents first, but eventually had to attack the problem with heat. It took a bit of heat, very carefully applied with a pencil style soldering iron to liquefy the old spoogy oil on the shaft enough to free that shaft gear. I held the flattened tip of a 40 watt iron right on the hub of the shaft gear until it was free enough to slide back and forth.

This required strong light, a small mirror and a lot of diligent care inserting that soldering iron tip down into the TG frame without letting it hit any wires or caps or anything delicate looking.

If you end up having to try this, ask a lot of questions first and be damned careful that you understand what you are doing and how it should work.

One thing for sure, you don't want to put any pressure at all on the gear or main drive shaft that could result in moving the TG shaft bearings out of position.

I hope that this makes some sense to you. I'm going to bed.

Subject: [CWSG] choice gift : a primo B-3

The soundman/techie at our community theatre called yesterday to
exclaim that a donation had just arrived:
a Hammond B-3 and a 122RV Leslie! [:)]

This morning, we hooked everything up properly, but could not get her to
fire up.
The start motor chugs away, but will not even budge the "driveshaft"
(much less bring it up to the speed needed to successfully engage the
run motor).
We put a careful amount of fresh, genuine Hammond oil in the cups, and
left it at that (for the time being), thinking that the oil will slowly
wick to the bearings, etc., and loosen 'er up.
Meanwhile, since there are no other Hammond players or technicians
around here, it's off to tap on the shins of the experienced giants on
Internet...

Do you guys have any further suggestions?

Sincerely, Rob
