I'm looking for this drive gear shaft, it's from the Lionel TMCC Sharks.  This one has a split brass gear.

Initially I thought it was just displaced, so I used retaining compound and secured it in place.  When it had a bind at one point in the rotation, I looked closer and discovered a hairline crack in the brass gear.

Anyone have one languishing in their parts box?

So this is from a 4 wheel truck. Are these different trucks from various engines using different gear sets? I am constantly amazed at how each product has uniquely different parts...no or little sharing of parts.

These are 4-wheel trucks.  I've seen at least half a dozen different truck designs for Lionel diesels, I'm not sure how many models used this gear set.  This is, of course, one of the truck designs that requires you to disassemble the entire truck to remove it.  I have a whole bag of screws.  The bummer is, I assembled it all after using the retaining compound and I thought I was done.  I was looking for the binding in the other gears cleaning everything.  I finally realized that something was amiss with the drive gear and with close examination I found the crack in the brass gear.

This particular truck design must not have been a winner, Lionel's parts department lists the RF16 power trucks as being "UNAVAILABLE".  I become a bigger fan of MTH with every passing day.

Where does MTH have their stuff manufacturered?

China.  But supposedly they have their own factory (can you "own" anything in China?), and they are very conservative when it comes to design changes.  They also use one basic truck block design.  I remember MTH took some criticism about 15 yrs ago when they switched their "scale" F3 to a RailKing truck block with a slightly shorter wheelbase.

The Baldwin B-B is a long-wheelbase truck.  I'm sure if Lionel used their EMD truck block on the Sharks they would have been criticized roundly.  That being said, why they wouldn't use the same intermediate shaft on all of these is a question that only Lionel can answer.

I happen to like back-drivable gears.  Depending on how much John's customer is willing to spend, if the pre-Legacy part is not available it might be possible to use LionDrive motors and truck blocks from the newer model.

Creep, coast, and pull.  We're not talking about cold fusion here.

Most of their stuff yes. MTH Premier steam locomotives are currently and have always been made in South Korea.

This happens to be mine, and I'm not ready to spend a ton of money!  In addition, the Legacy trucks are a totally different design and wouldn't work in the chassis in any case.

That's probably where I'm going.   I was hoping to find the bad gear, but for the dealer price, I think the truck is the way to go.

Nice, how did you find that one? 

You don't realize, in order to mount the motor on that complete truck, you have to completely disassemble it anyway!  So, I think I'll go for the gear.

Where did you get that picture?

Looks like those product supplement pictures.

First off GRJ you did not do us any favors by not listing a Lionel product number (you of all people).     I Googled Lionel Sharknose TMCC and got into some 6-1453# series.  I did a Lionel Product search and no hits. I looked up that number series in my 2013 Greenberg Guide and those don't exist.  I did a Lionel parts search with 14533 and that is where I found the truck assembly.  I could tell you were not thrilled with paying $38 for the truck so I kept digging.  I did look for manuals for the 14533 and found one for this AA set.  It had the year printed in the manual so I knew it was 2003 vintage.  I then went to the supplements looking for a truck breakdown.  The exploded view is from Supplement 47 which is 2004.  I found the picture and it listed the part number. 

I'm just glad I could assist GRJ for all the times he has dug me out of holes that I get in.  If anyone is keeping score.... GRJ 117, Steims 1.

I spent quite a bit of time in one of those 6 wheel trucks for a Chessie U30C.  Without the exploded view I was stumped for a long time on how to get inside the truck.  I do recall that particular shaft and challenges with reassembly.  My issue was the thrust washer on that the worm gear (on motor) rides in.  The truck is a robust design but it is a challenge to work on. 

 

I don't know about robust, otherwise I wouldn't be dealing with a split gear!

It's not so much that I really mind paying for the whole truck, it just bothers me that I have to replace the whole truck for one little gear.

The problem with putting these back together is you have to get all the sleeve bearings aligned and then stuff the motor down on them without moving them.  I remember years ago when I first encountered one of these truck designs.  I couldn't believe you had to disassemble the truck to get it off the locomotive after working with the MTH and Williams trucks where one screw did the job! 

Sorry about the item number, that isn't like me to omit that.  It's 6-14533 BTW.

It's fantastic the help you can get sometimes on these forums!  How many has GRJ helped over the years? - Countless including myself.  Glad Steims was able to help him.

I think I have one of these gears some where in the parts stash.  I recall it wasn't fun changing out the couple I've done for folks.

Looking at these two gears they do not look the same.  Maybe it is the angle

Hard to tell from the picture, if the gears were right, the brass gear is easily pulled and use the old bearings.  Those may just be oriented so you can't see the cutouts.

Pete, that's only if the correct gear shaft is still available.   There is no pictorial for the Sharks, so it's not clear if that individual part is available.
