Lionel whistle tender...more noise than whistle!

[trains4fun]

The electrical and oiling have been covered, cleaning out the whistle chambers is covered. I have checked these on all my whistles. What do you do when one of the 2 whistles in the whistle box don't work. I have been checking and I find all my tenders work on the high note, the top on a vertical mount, but some do not work at all on the low note. Anyone know how to get the low note tuned in so it works? The low note gap is slightly longer it seems. Thanks

Could you please repost the oiling instructions again? I have a 2426w and even after cleaning it out it only makes a grinding sort of noise, no whistle at all... Not exactly sure where to oil it.

... is there a specific parts breakdown document available so I know exactly WHERE to oil...

 

 

Here is a diagram of the motor with the armature removed. Oil both ends of the armature where circled in red. The lower one will require a needle oiler down between two of the three poles of the armature.

Thanks, the upper is simple enough, but I'm confused about the lower-- it appears that the shaft of the armature connects to the impeller first, so I can't get at the bearing without removing it somehow (wouldn't that stop the oil?). I think that oilite bearing is my problem, because it's obvious when turning it by hand that it isn't lubricated at all. My tender runs but doesn't actually produce a whistle, apparently because it isn't getting up to speed.

If your whistle looks like this (see rear view), then the bearing is pressed into the cover and is accessible to oil from the outside.

Yes, that's close. You're right-- there is an oil hole there. I thought the bearing was solid on the outside, but it had a bunch of carbon plugging up the hole. It's spinning fast now, but still no whistle- only the noise from the motor! I'm starting to think that there must be some defect in the actual whistle mechanism, even though I don't see any evidence of metal fatigue, etc. Perhaps I'll have to just switch it out with another whistle...

The whistle chamber may be plugged. Take off the motor and check for anything obstructing the air holes. Blow into the chamber and it should produce the proper tone.

The other more likely reason for no sound is that the motor is wired incorrectly and is turning backwards. Make sure the motor is turning in the proper direction, or no sound will be heard.
