Anything Can be fixed you just need a little patience

I just wanted to share a trick with you on Lionel motors that where used in most TMCC diesels between 2000 up to the legacy release.

I stumble upon it with the use of my favorite tool.... yes that is the claw hammer!

Ironically the most destructive tool on the work bench has in the past been my most helpful tool in repair lately.

 

The F-3's/ F7's released around 2000-2004 tend to have one motor that travels faster than the other, causing all sorts of issues.

I found one the other day the the motor was just seized up and tough to turn. So instead of doing the knee jerk reaction of ordering new parts I wondered if I tapped lightly on the end of the motor shaft top and bottom it would free it up... and it worked! (TAP LIGHTLY)!

Not a big deal you say? but when the motor is always the one with the odyssey board on it that goes (seems to be my luck), it may save you some coin... you will have to replace it and hit with a hammer if this trick does not work anyway ... The picture below is of a modern one w/o the boards, the culprit seems to be the older motors with the larger brass flywheels....

Well that is one perspective... but to be more specific, this is the bad boy motor I am talking about. I am wondering if Lionel had a bad batch of these back then.

If you tap from the worm up first gently, then check it by spinning it. 

Then tap gently top down, careful not to hit the flywheel into the sensor, add a bit of light machine oil on the shaft to motor housing and you should be good to go.

Good find, I bet you also feel better ....

The wife get's stuck once in a while...

Do you think this will work on her ?

 

 

You mean, in that continuous loop of sound emanating in an unceasing flood of endless, meaningless syllables and phrases?

 Oh I see you have met her .......

 But loud chuffing and a lot of smoke will send her

 back to the cave for a while....

Interesting info.  I had a can motor that had a similar issue and found that the can had a bend at the bottom bearing.  The owner probably tightened it down while cocked on the gear.

 

Turns out I could apply slight pressure and the can bearing area snapped back into alignment.  Metal was still in the elastic region.  Motor worked fine.

 

I always like to try to find out what specifically failed.  Recently had a Truck on a diesel that would lock up at a specific position.  I could not find anything really wrong internally with gear teeth and such.  If I shimmed the motor away from the gear I could get it to not lock up.

 

Owner wanted a new truck vice the shim, so I decided to remove the wheel, press the shaft out of the gear, and found the gear had a split in it.  The split caused the gear spacing to close at that area and that is what was causing the lock up.  

 

Of course I can send you some items your not going to fix with the hammer, unless it is a magic wand also!    G
