UPDATE.....NOV 27.....POSTED A LITTLE FURTHER DOWN ON THIS THREAD.

 

 

My AMC/ARC Gantry Crane 6-24114 came out of storage and would not run.

 

I took the gear boxes appart to find the grease had turned to the hard wax like substance creating major resistance.

 

I cleaned it all up and installed new grease.

 

I need to replace one motor and at least one of the "rubber belts" that is used for the drive.  It resembles a large traction tire.

 

Lionel's site does list the "Motor Gearbox Assy @ $26.00" which includes the plastic housing I really don't need.

 

However, there is no mention of the drive belts.

 

Can anyone advise where I might get the motor only and drive belts?

 

Thank You

No sorry, not exactly right now. But for $26 the assembly might be the fastest, easiest way to go. You already know where to find it and a motor & belt will probably cost at least $15 total. I was kind of surprised at the low Lionel price.

NA-not available? Finding and matching can motors isn't usually too hard. A good RC/hobby shop should have a good choice, electronic repair & supply shops can often find drive belts by description. If you settle on an old fashioned rubber band, check it every now and then for cracks or slime indicating breakdown/melting from contact with incompatible plastic. 

Thanks Gents

 

I may have misunderstood.

When I looked at the Gear Box Assy listed on the Lionel site I thought it was just the motor and plastic housing.

 

Does anyone know if all the internal gears and rubber drive belt come with it?

That would be ideal if that is the case.

 

John.  I used a traction tire to temporarily substitute but it is not the right size and too tight.  The original was also not near as wide.

 

Hokie....I've emailed Chuck for parts as well and will post my findings, thanks. 

 

Adriatic...I too thought of a rubber band but it is a bit of a pain to get into the unit and would prefer the more longer lasting heavier belt, thanks.

UPDATE

 

I contacted Chuck at DENVERTRAINS who was a great help, sending me all the parts I needed.  Great Guy to do business with!

 

The gearbox is indeed one piece with motor, internal gears and belt.  I have posted  picks here of what one looks like.  As John said, there are different size belts.  Some are narrower than others which tend to be more round.

 

When using this item, as OLD/NEW stock.......you will have to clean out the original grease within the gearbox which in my case, turned to "wax".

Re-greased with Red and Tacky.

 

Happy to report that the crane is up and running nicely.

I was able as per instructions to vary the speed of the cab rotation and hook up/down with my Legacy system.  Nice feature.  The cab rotates too fast otherwise.

 

However, I have 2 questions left:

 

1) Why did Lionel change the belt sizes?  The groove on the motor shaft is longer for the wide belts and the motor seems more "robust".

 

2)  What purpose do the resistors serve that are across both posts of the motor?

 

Thank You

You sure they're resistors?  I'd suspect capacitors to knock down the electrical noise, I can't think of any reason for resistors across the motor.  They don't appear in the schematic.

 

I looked on Lionel, the black component on the motor assembly is a non-polarized capacitor.
