Hi and thanks in advance. I have oiled all moveable points on the outside: axles, screws, rods,... I think the squeak is internal.
Here is a link to a movie I just shot.
Can anyone suggest what I should do next?
Thank you,
Jon

More than likely the motor has developed a squeak,..

Well first off, the frequency of the squeak is NOT the rotation of the motor- it is in sync with the rotation of the wheel. So no,it's not internal, it's external. Most likely one of the crank pins or the eccentric cranks.
I watched the video 3 times and again, no, there is no way it is the motor that is spinning several revolutions, nor the driveshaft, nor the gearing.
Again, it is squeaking when this wheel is in this position multiple times in the video in the same place of rotation every time- so it is definitely tied to the wheel/axle and thus the linkages and all those pivot points, not the motor spinning several times faster per revolution. Again, notice the time stamps in this clips and the position of the crank and I tried to get near the exact moment the squeak was heard clearly in the video.
now granted, it could be the other side, but consistently, it's tied to that point in the rotation of the wheel/axle system.

I suggest just continuing to run it in and lubing the crank pin joints and the eccentrics on both sides. It either just hasn't lubed the dry spot yet or has a slight burr or defect in one of the parts that should wear in. Don't go nuts and overlube making a mess, but again, just didn't get the spot (my guess is normally the eccentric crank since the connecting rods have several parts there all in the same spot).
Also check the brake shoe detail.
The shoes on the engineers side can turn into the wheel possibly touching it.
I normally loosen the brake shoe screws and put a small flatblade screwdriver between the wheel and the shoe. Then retighten.

Don’t shoot me Vern, ….I completely missed the video link!!…I was only going off the description of what was done….

Thank you everyone. I will keep working on it. I appreciate your insights and efforts. Jon

Sorry if you took that directed at your post in any way. We all were trying to help.
My reply was meant to the OP.
FWIW, background, at my local club, of course everyone comes in showing off whatever new they got that week. Being in the repair in troubleshooting, I see sort of "my engine is making a noise" on a weekly basis, plus all the repairs I get through the local train shop.
Just saying, I see this kind of problem more than any one person in the hobby should.
Also, I have a really good set of speakers on my computer and turned up the volume quite a bit when watching the video.

Vern, I’m just taking a jab at ya man, …..😉
I agree with you, the squeak is external, …..Jon needs to double check he’s lubed everything that spins and moves. From the pilot truck wheels, to the trailing truck wheels. The rule of thumb, if it moves it needs lube…..if the lubricants he’s using are not up to the task, it’s time to up the viscosity,……
Pat
Yay! The machine is absolutely quiet. I continued the lube process until the squeak went away. Check out the new video that has no squeak at all. Thanks again! Jon
