I have a couple Marx 999 engine motors that are stuck in one direction.  The e unit will cycle but only run in one direction, one motor in forward and the other reverse.  I have sprayed them with contact clear to no avail.  I can not see the contacts like a Lionel drum e unit but the little pendulum wire move but only from down to front or reverse but not to both.  I am hoping not to have to remove the e unit and pry it apart to try to fix it.

Any easier way to fix it or see the contacts to clean?  Thanks for reading.

Thanks fellows for the suggestions

Ont  Sou      I have tried using a tweezers to work the actuator rod with no good results.

Dallas    Do you mean reversing the wires to the brushes?

I have found an old Marx motor that works in both directions for the 238 Torpedo and has a low e unit for mounting.

But I still have two motors that go only in reverse (but are not needed for now) and two Marx 999 that only have reverse I would like to fix or at least go in forward.  What is with these Marx motors that they like reverse or fail in reverse?

Charlie , I'm not familiar with the Marx engine but on my conventional post war Lionel I would switch the leads to the brushes on the motor.   On the MTH or newer Lionel can motors  I would just unsolder the motor leads and switch them and resolder.

I have a Lionel conventional  Gp38 with horn that began to only ran in reverse until I switched the wires .  It runs in forward only now.               It was a Lionel from a time period that had a history of bad electronic reversing boards .                                   I guess the boards are available but they are expensive so I'll have to be happy with forward for now.

Good luck   🤗  and be safe 😷
