pendulum reverse units

I think Olsen's library has that info online.

Chuck is correct.  It is located at Olsen’s Toy Train Parts, in their Library , under Prewar section.  “Reversing & E units”.  It shows two listings, E-65, E-65X.  65 has 5 nuts, 65X has 7 nuts, for contacts.

We have available replacement 'switch contact sets' for the pendulum. They were made in copper and include the attaching rivets.  The original contacts are quite often burnt w/ a hole in the contact area making them hard to be reliable.  Harry 

Do you still have the standard Scale pendelum reverse units for super motors. I have several I am restoring and about 1/3 of them I have been able to get them working 90%. Would want to buy some complete units with the headlight terminals if available.

If Harry doesn't have them. Try Jeff kane

I have a pendulum reverse unit in my 384.  It works, but is tricky...  trying to find the right word.  Let’s just say I only run in forward so I have the lever fixed with a bent paper clip and a piece of gorilla tape.  A bush fix perhaps, but it works great and can’t be seen, being that it’s underneth the cab.  I admire your want to get your’s working as it was meant to be, but I kinda think they didn’t work that great to begin with, so fixing it in the forward position has been the right thing for me.  My engines run in loops, and are all fixed in forward.  I’m not doing any fancy switching maneuvers.  Best of luck if you pursue this.

Cheers,       W1

I did two pictorial type videos with annotations on the Pendulum reverse recently :

I had a problem with sporadic operation which I conquered here:

Hopefully these will help someone!

RKenney - I’m a Kenney too, if that is your surname.  William Kenney here.  Glad to see another Kenney who spells it correctly.  With the second e.  It’s an easy name to spell, but gets misspelled more often than not.

Cheers,       W1

Bob Kenney here.  (Robert on my birth certificate)  Used to think there were no other Kenney's growing up, at least few in our phone book.  The internet has certainly changed that idea!

Have a brother Bob.  Another brother John.  And four sisters.  Plenty of Kenneys around here, Chicago area.  We like to multiply.  Keep the heathens at bay.  

Made me smile Bob.  Glad I asked.  Now back to the task at hand.  The pesky pendulum reverse unit.

What I found was simply an inconsistent ground for the solenoid through the grounding lever.  I guess it was better when new but the small pivot points just didn't seem reliable or consistent.  By manipulating the lever (bending) I got it to rest on the brass frame crossbar in the closed (current off) position which made a much better ground.  Works every time now!

Hi all does anyone know where I can find information on the prewar pendulum reversing mechanics.Am interested in the wiring,how it operates and if anyone sells parts for it.If I am correct I believe they were also pared with the wafer switch to lock it out.

I have several engines with pendulum reverse units, and I have completely overhauled one.  IT's a DPDT switch that looks complicated from the outside but is actually very simple.  They all have a lever that mechanically obstructs movement of the pendulum.  There is no electrical contact.

There are detailed drawings of the pendulum reverse in Greenberg's new O gauge book.  Unfortunately it's a $100 book - well worth the price if you're into buying, repairing and selling prewar collections, as I am.

Mine the solenoid buzzes.

Jeff Kane had one. So I know what They look like. One if these days I'll get it in. Right now locked forwards.

Bob hannon explained what could be problem.

Won't know till it's apart.

Here is a pendulum reverse Bulletin published in 1986 probably after parts were no longer available.  Forget were I found it but it was originally printed on blue paper (non-photocopy back in 'the day').  I erased most of the blue to make printable mostly black and white copies. The second page shows wiring for a later model drum type E-unit that can be turned off with a toggle switch.

I have the contact repair kits in stock, #259E-P @$5.00 + $4.50 shipping.  This is a 3 piece set w/ rivets. Listed on our website.  Harry 

Some more useful pendulum talk on this thread: https://ogrforum.com/...endulum-reverse-unit

Great stuff I will keep copying the info in my little notebook.

Thanks

Where is your website can you send me the link that would help a lot. I am not much better on the computer than on the Pendulum reverse's either.
