Hi,

 

  Picked up a trolley the other day and I need to tend to the pantograph.   It appears that when the trolley changes direction the pantograph also changes the directions, but the pole it self sometimes swings out too wide.  When I looked closely at it I noted that there is a small guide hole in the black piece that holds that will keep the pole in place.  I would like to remove the black piece from the trolley so that I can reinsert the pole back into the guide hole.  How is the black plastic piece installed?  Is it just inserted into the hole or is is secured/glued in any way?  I would rather remove it in order to work on the pole then trying to do it while it is attached to the trolley and risk any damage.

    I did a google search along with searching the forum and could not find anything helpful.

 

   Thank you,

Hi, Kevin!

 

There is no pantograph on the No. 60 trolley--just a wire trolley pole that changes position when the trolley itself strikes a bumper and changes direction.

 

It is not uncommon for the pole to not line up parallel with the car body when this action occurs.  That always bothered me a bit, but I never have spent any time trying to figure out how it might be corrected.

 

That black plastic assembly just lifts off the connection rod inside the trolley.  Just pull straight up and it will come right off, as will the wire pole itself.  None of those parts are glued...simply a press-fit deal.

Some #60's the trolley pole will swing a correct 180 degrees so the pole is parallel to the body in both directions, most will swing the pole around 220 degrees. The reason is all Black lettered and many early Blue lettered units have a 2 piece spring bumper slide and it has a cut out gear segment in it. It wasn't punched out with quite the correct ratio for the pinion gear that the trolley pole shaft is connected to. The later Blue lettered version has a solid one piece bumper that doesn't have the spring in front. This new stamping has a corrected 'gear ratio' and swings the pole in a true 180 arc.

So no matter how long you fiddle with early version, the pole will always swing wide to one side. This late version also has the vented roof.

A note as far as operation, always use a 260 or later version die cast bumper with the sprung buffer. The later all plastic solid bumpers don't work so well, the spring is needed to absorb the shock without derailing the car.
