Hello everyone. The left handle on my postwar ZW has come loose. It isn't too bad, but when I move it, the roller arm doesn't start moving right away. It's almost as if it has "play", like a car steering wheel. This makes it difficult to shut off power completely at times. If I push it in, then move it, it seems to work for one move.
This is the big handle, the one which the whistle is connected with.

Did you check to see if the metal ring came off? Or it is worn out on the inside.

If you need a metal ring, let me know. I have some extra. If the handle is worn or broken where it meets the spline, I can help you there as well.

Thanks guys, but I am not sure what ring you mean. I took the top off my ZW and looked at it and cannot see anything wrong, even when I compared it to the other side, or the same side on another ZW.
pull off your outer handle and look at the hole where the sline shaft is inserted. Is it damaged or worn. Inspect where the short contact arm is mounted on the shaft. You should see a retaining pin that is locked in by two ears on the copper contact arm. These are the only areas that would cause slippage in the outer control handles.
sounds like he hasnt pulled the handle off yet get a 2 inch 4-40 machine screw screw it into the hole on the handle. this slides handle off the shaft. inspect as stew suggests. my guess is handle is worn . repros are cheap and readily avail. then contact poster hah3 as in above poster. [hennings]
I can attest to the fact that Harry's place has LOTS of ZW handles. 
Thanks guys. Realizing that the handle is just pushed on, I gave it a good push this time, and it seems to be working fine now. If I remember correctly, it is a replacement handle from the 90's, so maybe it was just coming off? Anyway, if it happens again I will get the screw to take it off and report back.
