As you can see the drive shaft connected to the gearing that provides up/down motion spins loose so the plastic gear doesn't move. Any suggestions on repairing it here at home would be appreciated, I really don't want to take it apart since the connecting thread is involved.
thx

Lionel used to have the gears. They are nylon, shrink with time and crack. I drilled a hole in the gear all the way through and used a piece of music wire to keep it from spinning but it would catch on every revolution where the teeth had spread apart. No glue will hold nylon together. Best replace the gear. BTW its not as complicated as the TMCC wrecker crane. Not a big deal to reinstall the thread.

Nylon huh ****
If this is the gear that is slipping you may have to find another source as its listed NLA. Not surprising.

It is going to have to come apart no matter how you look at it. I have brass gears to replace the nylon one. I can do this service for you if you like, or sell you the gear.
Chuck send info to me if you will

Chuck, I'd like to hear about that gear as well, it's only a matter of time before I need one! 
Definitely spend the extra money and get metal gears in place of plastic.
John, it is a reproduction gear for the pinion gear that always breaks. Jeff Kane (train tender) has them available. I have installed about a half dozen and they work fine.
Thanks Chuck, I know how to get a hold of Jeff. Maybe he'll be at York again and I can pick it up in person.
John, I had gotten in touch with the Train Tender before the spring York meet and he said he would not be at the Sping meet but would be at the Fall meet. My MI Jack needs repair (I think I might have mentioned it to you one time at Hennings). Get a couple of gears and I will have you fix mine.

I'll be checking with him.
guys I would like metal gears as well. does jeff have a websight? I am unable to go to york anytime soon thanks.
btw if we install all metal gears in the intermodal crane can it then lift up heavier containers from other manufacturers?
Jeff's site it The Train Tender.

You also have to deal with the Thread/string for a cable. That too can easily fail under a heavy load!
Stringing the Mi-Jack is child's play compared to restringing the TMCC crane!

Ok then is there a fishing line that someone could recommend to replace the crappy string?
