1666 e unit drum

[oddmatt]

Hi, I'm new to the forum. Basically the e unitDrum was not sitting in housing correctly and had turned sideways...all the leads and contact fingers look fine just making sure that when I reinstall it I have it the correct way...I'm thinking the plunger should be grabbing the" gears" on the drum...is that correct?

Welcome to the forum, Oddmatt. I have attached a youtube link that shows how to install the plunger, 4 finger contactor and drum. The installer used a special spreader tool to assist in the installation but normal tools can be used. Good luck. https://www.youtube.com/watch?v=mA6AdfzXo3g Swede

Thanks! Got it to work on a bench test...however still no dice (sticks in neutral) once reassembled....Ordered new drum as I had attempted a repair on the original bc the spindle tabs had worn off where it sits in the housing...hopefully new drum is the answer

There are those that say you should not oil an E unit. I disagree.  A small drop of oil on the drum shafts will prevent wear and failure of the drum.

Use motor oil as it does not dry out.  Don't use 3 in 1 oil, Lionel Lube, WD-40, lithium grease or any other grease.

I use motor oil exclusively to lube my stuff.  I even oil the commutators on the motors.  Some guys tell me I shouldn't do that, but it works just fine, and the motor friction is lower with oil on the commutators.  I may put oil on the E unit drum to prevent wear on the fingers.  

I have been running Lionel trains since 1950, and have repaired only 2 E units.  One was not my loco, and I did the repair when I was about 13.  The other was a loco I had just purchased and the E unit had been hot.  This repair was done about 5 years ago.
