Lionel Century Club Shark Jerks in Forward and Reverse

In your manual you may find the simple procedure for Reprogramming Your Engine.

It may help.

Thanks Soo Line! I tried that earlier and it didn’t cure the problem. 

Traction Tire?

Could be? But I just finished running it on a short test track (40 inches) in convential and it seemed to run good. No jerking. 

Well Dave,  that is about how far my on the job training takes me at this point !!

Will be interested to see what the fix will be.

Dave

Dave, thanks for your help. I’m thinking that the problem is electronics not mechanical. After I ran it in conventional I put it back on the layout and ran it in command. Still jerks/hesitates. I hope someone with more knowledge than we do can help.

Dave

Ok, so please confirm. Conventional everything is ok? Your issue is only in Command?

J Daddy, the engine runs smoothly in conventional, although at a higher speed than I thought. In command it jerks/hesitates when starting.

NCDAVE,

       If you are using a Legacy CAB II remote make sure the brake slider is not on, in fact work it up and down as sometimes the breaks stick.

John,

Thanks got the suggestion. Since I'm using the TMCC Cab1 remote would that suggestion apply to the brake button on the Cab1 remote too?

Dave

What is the track voltage while in command?

Marty, 

Its 17.5 volts

I don't remember if those had a switch for the cruise or not but if it does try turning it off and see how it acts. 

Doug

Dave,

    I do not think the CAB 1 remote has a brake slider like the CAB 2 so I would think not. Sorry it has been a while since I used a CAB 1.

JohnB

Doug, I thought of the same thing. Unfortunately it doesn’t have a on/off switch for cruse. 

Hmmm, it seems odd that oiling the axles and putting grease on the gears would cause the electrical problem. Did you remove the motors and put grease on the worm gear?

Doug

Doug,

It does seem odd that greasing the gears and oiling the axles would suddenly case a problem. And no I didn't remove the motors to lube the worm gear.

I just noticed that while running it with out the shell there seemed to be a lot of mechanical noise coming from the front truck/motor area. Any suggestions?

Removing the motors could be an issue if you have a problem with alignment.  I've seen more than once where the motor had to have a small shim to stop binding, probably a defective motor or motor mount, but I just fix them and move on.

John,

I didn’t remove the motors to grease the worm gears. Could one of the motors slipped out of alignment when I turned the engine upside down to lube it? 

I doubt that could happen,is the motor loose on the mount? Another thing to check would be the magnet ring on the flywheel,is that broken or cracked? 

Doug

Doug,

The motor doesn’t seem to be loose on its mount. But I’ll check the motor and the flywheel magnet latter today. Thanks for your suggestions. 

How about a video? Cab off too? Seems odd that you would have cracked the magnet ring to grease it.

Bobby,

Here’s a short video
