I need some options please.

A number of years ago, I got a Sullivan Starter with a Robbe wand already attached. The sullivan is so big that I decided to leave it in a drawer while I used my smaller and lighter Hangar 9 Starter. Well, the time has come when the Hangar 9 starter is showing it's age. I was planning on using the Sullivan to replace it. the problem is that since i got it used, the Robbe wand is a little worn and is not centered. This thing wants to break my helicopter before I fly it, it vibrates so bad. I have a regular starter cup and rubber inserts for it, but I can't get the Robbe wand off. Could anybody give me some pointers on how to get it off without damaging the starter? If the wand survives the ordeal is a plus, but I don;t really care.

Here is a picture of the Robbe wand for those of you that don't remember:

Had the same problem.
i did spray a lot of WD40 into it where the small "cut" is and heated it up in the oven.
That did the trick.

Wouldn't the oven melt the "insulation" of the wires on the motor stator? What temperature did you use and how much did you disassemble the starter?

I could also try direct heat from a torch or similar.

I just did put it in the oven at 60 degree celsius, a fairly low heat.
that was enough so the WD 40 could do its job.

There are two traditional ways:

1) hold the wand (vice grips) and reverse the voltage on the motor and spin it off. Can break bones.

2) take the brush end cap off and hold the motor shaft in a 1/2 inch drill chuck and remove the shaft.

I am assuming the Robbe screws on and is pinched with side bolts ?

That is the question. It has a single set screw on the motor attachment part. So it must be screwed on.

Sometimes this one has been fitted with loctite.
If - then a torch is useful

According to a guy on HF, it was tapped 1/4-20 ? (not important) and screwed on after purchase. Maybe with loctite as well ?

So suggestion #2 above is probably it. I have done this several times just to get the aluminum cup off. A 1/2 chuck will not barf up the motor shaft.

No, it isn't. The hole at the base of the wand is UNthreaded. There are 2 small keyhole type cutouts at the bottom that look like they want to fit onto 2 'wings' of the motor shaft. The setscrew merely locks it in.

I've always used mine w/ the standard starter rubber cup for easy breakdown.

Frankly, I'd just hit it (the motor shaft/wand interface) w/ a mini-torch to heat up just the local area.
