Atsf Legacy 4-4-2 Atlantic E6 6-11117

Update - was able to get the flywheel off - the hard way with a tiny screwdriver. Does anyone know what metric allen key fits the allen screws? The encoder ring is press fit? I can rotate on flywheel?

Before you do anything, clean the glue residue from the flywheel so the ring will seat properly.  Just set the ring on the flywheel, it is not a pressure fit.  After it is seated, very carefully flow a small amount of super glue on the crack between the flywheel and ring.  I use ZAP CA in the green bottle.  Do not try to put glue on the inside of the ring or outside of the flywheel because when those two metals touch, , the super glue will set very fast and chances are about 99 percent you will not get it seated properly.

One last tip.  When you order the ring, order a few as they are dirt cheap and fit many applications.

Thanks the original was not glued at all. It looks like they swedged the brass on the inside of the encoder ring to hold the part onto the flywheel. Thanks for the help.

Shawn, I have seen that.  It only needs a very small amount of glue.

Marty,

I used 4 small dab of glue....worked out great.  I picked this engine up for 200.00

on a auction site...nothing like 4 dots of super glue for repair cost. 

Nice work, what were the symptoms you found that showed repair to be necessary? 

I suspect lack of speed control.  The Legacy stuff runs a few feet and if it doesn't see tach pulses, it stops.

The engine when put in speed control would start then slow, then speed up. The encorder ring was loose. But, the ultimate issue was the counter balance on the shaft. The counter balance is locked in via 2 allen screws. When, I would turn it. There was a small amount of play. Then in would engage again.

Yes, The counterbalance was not locked down tight to the motor shaft. It would slip a bit. The engine would spped would breakup.
