I just completed a service (re-wire, new brushes, overall cleaning...) on a newly acquired tender.   It wants to whistle, but it "screeches" more than whistles.  I should note that prior to the service I did put it on the track and noticed the relay was functioning but no movement of the armature.  I read through the Greenburg repair manual but can't seem to associate any of the trouble shooting issues with the screeching sound.  Any suggestions?

BMORAN4 - you had me confused for a second, my tender has the WS-66 Brush Plate Assembly.  I wasn't able to remove the armature so it could be the Ball Bearing WS-106 or Bearing (housing) WS-107 is in need of replacement. My Greenburg manual identifies a Grease Retainer WS-53, but no mention of a Wick  

@JKK, didn't mean to confuse you - just going off of your statement of having a 2466W which is reported to have the WS-125 motor leading to the parts breakdown previously brought to your attention:

With the WS-78/85 style and similar, you are correct that the armature is captured and the repair more difficult. It involves removing the cover assembly and gasket and drive studs to access bearings and bushings for replacement. Not impossible, but not elementary.
