Lionel can motor pinion gears

A picture of the pinion gear would be helpful. Also here in the states we have a couple of guys that can rewind/ repair almost any O gauge AC motor.

Thanks Chuck........I've added some photos of the Lionel motor and the plastic pinion gear. I've also included a couple of shots of the new Buco "304" loco on my layout.

Get yourself some Loctite 660 Retaining Compound.  Use this to secure the gear to the shaft, you shouldn't have any more problems.

Neat looking stuff you have there!

Thanks Gunrunnerjohn for the tip about Loctite 660.....I'm off to the auto spare parts store to get some. Thanks also for the compliment about my Buco trains, I also have a large collection of Lionel, Williams, and KLine steam and diesel engines I run on my Buco brass three rail track.

Thanks also to KD for the link to Northwest Shoreline for a possible solution for a pinion gear replacement. I will check out their website as well.

I think you'll find the Loctite 660 will do the trick just fine, no reason to screw around replacing gears.  Just make sure you get the gear aligned reasonably quickly as once the stuff sets, it's difficult to move them.  In a pinch, a heat gun right on the gear will break the Loctite loose.  You have a few minutes to adjust it, then leave it for a couple hours, all fixed.

I tried securing the plastic pinion gear (when it initially came loose) using "Superglue", but it didn't last long, so I hope I will have better success with the Loctite 660.

Totally different stuff, and used for different purposes.  Here's the Loctite 660 Description.

This is what I have. It is a can motor that looks like the one you have. The gear is a 9 tooth pinion. It is steel and not easily pulled off the shaft like a brass one. Lionel doesn't have the pinion gear separately as it would be almost impossible to push on without damaging the shaft without a special jig.

Superglue does not like "shear", "twisting" forces (which is essentially what you are trying to fix), only pull.

Even if you chilled the motor and heated the gear first?

I don't know if that method works or not. But if Buco finds a brass replacement, that is soft enough metal it can be tapped on the motor shaft if care is used.

Ohh, I recommend against tapping a gear or flywheel onto the shaft of a can motor.  I've seen several instances of that being tried and the result was shifting the commutator and killing the motor!  You need to press those on and make sure the back of the shaft is supported when you do.

Try these 2 numbers 620-8857-100 and 620-8875-100. These have different rpm value.

You can always get a brass gear with a set screw.  Just find one online that has 9 teeth and the 1.9 diameter.  When it comes, out some medium strength loctite on the set screw and then screw it into place... that should hold for a very long time.

Evan, a 1.9" diameter?  Are we looking at the same gear pictures?  I've never seen one this small with a set screw.

He said 1.9mm so I thought it would be understood that I meant 1.9mm.  Not 1.9" of course lol.

Thanks guys for all the help. I will persevere with the "Loctite 660" solution for the time being, but will further investigate the two part numbers supplied by Bob Karas, as I have seen these part numbers listed on a Lionel spare parts dealers website (Tranz???) when I searched for model train brass pinion gears.

Thank you all once again for the help and quick responses.....very much appreciated!!!!

I figured that out after I posted.  In any case, 1.9mm gears are not likely to have setscrews, nothing to thread into!

They make them with set screws for R/C cars.  I know this because I used to have a nitro car that needed the exact same part and found one with a set screw.

Here's an example:

Your graphic comes up as an error.

If they have one with a set screw and the proper shaft diameter, that would be useful.

Here you go John

Actually maybe not.  There seems to still be an issue with the composer. I waswoffered no "insert tool" as checkbox or in the listing at the photos near the bottom. 

Ive had trouble posting anything here the last couple of days. The amount of jibberish thattthe spell checks process mademthe task unbarable. Ih assumed because I could post at all that it was fixed. (The spelling fun here is nothing compared to yesterday. Clearing caches did nothing.

Still gets an error here.

John,
This is what he is trying to show.

I've seen that many times, clearly there is a problem with the graphic.

Could you email me? I'd like to talk about your Buco items.
