I just looked. I'm likely a different Mike, but here goes.....

Its called 'drawn pinion wire' and can be found on page 21 of their catalog



stocked in four-foot lengths.

You'll have a challenge to drill the stock, you'll need a lathe to center drill and cut-off the stock.

May I suggest for anyone that is thinking of experimenting with gears, you buy the very cheap Chinese gears and prototype with those, then move to the Didel miniature gears which are precise and quite moderately priced. Use them like you see the Athearn power trucks gears in their classic power truck design with the gears running between two plates.

I seriously doubt you will be able to have direct replacements for gears like the ones in the Bachmann engines. BUT, if you want to enjoy trying out custom drives with pocket-money, go for these gears on eBay..... available from several folks on there......

these are recent buys of mine and now are closed listings

It just can't be that there are no other sources for tiny gears, other then the cheep plastic gears from China. (The Chinese do make good Egg Rolls, though)

What about Clock Repair suppliers?
There is a guy here in Columbia who has a clock repair shop. I have used his repair service, maybe I'll slip by there and see if he can steer me toward a gear supplier.

As for gear noise, I hardly see that as an argument since we're inevitably talking about just the axle gear, not the whole gear train. Making axle gears from brass, especially if they are of a small enough diameter to be almost pinion sized should be industry standard. Either that, or make the gears larger diameter (like Mantua, e.g.) so they have enough material strength to prevent splitting, even over a knurled axle.

It's interesting that aside from early P2K, the cracking problems seem to be occurring mostly on steam locos. You'd think it would be the other way around, since larger drive wheels gives you the opportunity to use more substantial gears, as I mentioned. Metal axle gears on diesels would be more difficult for manufacturers anyway, since the modern Athearn-style design they've all adopted uses a split frame truck with the gears serving as insulators.

Hang on. You purchased a well-out-of-production unit, new at a hobby shop, expecting a 30-day warranty and it broke in half that time?
Warranties will be 30, 90, one year, quasi-lifetime, but the question remains:
Why did the hobby shop sell you a NOS engine with no warranty remaining?
Seems without full disclosure, they should be liable and responsible for returning your money.

Dennis, I agree with you to appoint except the engine was purchased new from a hobby store and broke within two weeks from the purchase. How was I to know that it was out of warranty. Most manufactures cover items within 30 days of purchase.

When the "older" models were made , there was always the possibility of parts to repair them ? In our brave new world ? Almost never . I don't believe he newer Plastic locos are made with an allowance for parts ? If they are , stand by for the price Pilgrims ! It does seem pitiful that you would have to "fix" it yourself ? Ah well .

So much for Athearn support:

Dave,

Thank-you for your inquiry and long time support of our products. We

regret to hear about the problem that you have encountered with your
locomotive. Unfortunately we cannot help you resolve this problem with this
long discontinued and out of warranty locomotive. Please note that your
model has been discontinued and out of production for about 12 years now.
We no longer have, nor can we get, the parts needed to fix your model
because the company that produced these locomotives for us, Samhongsa, has
been out of business for many years now.

If the locomotive's drive axle gear is the issue it is our understanding

that Northwest Shortline makes/made a replacement gear for this engine.
Their part number is/was 2147-6.

Sincerely,

Athearn Trains

DM, & Everyone,

This problem is really a pain in the butt. Since the gradual
curing/shrinkage must be known by EVERY manufacturer, the continued

use is

unconscionable.

The manufacturers have responded to the market with all sorts of

additional

goodies added to our models, and added to the price, what is the

reason for

continued used of plastic gears????



I recently sold a P2K FA & B set that had not been used, but had read

so

much about the inevitable split gear problem, I decided that an old

modeler,

such as myself, didn't need to hang on to them. I do not recall split

gears

on Mantuas, Penn Lines, and Bowsers. Maybe it happened, but I have

had a

number of them, and that was not the problems I experienced to get

them

running, or built.



I have a Genesis Milwaukee Road Mike that hasn't been out of its box,

except

for some upgrades. Should I expect this thing not to run because of a

10

cent gear? All the bells & whistles added to a model such as this,

makes it

all the more frustrating when the thing won't run because of this

curable

problem.



I remember fixing the cracked axle parts of Bachmann's Hong Kong

Northern.

It was a real pain to fix the OEM axles, but these were good looking,

cheap

models. This is not the case with a Genesis having a similar

problem, it

is not a cheap loco, and shouldn't require the buyer the effort of

fixing

it.

Denis
The PK2 s are east to fix...but for how long? I called walthers

because of a split gear & they sent me enough axles w/ the gear for
every P2K i had for free.
Don't think this works now but the Athearn gears also fit. The reason
for the plastic gears is to keep the noise down...especially now with
sound systems so prevalent. Seems if they put a knurl on then shaft it
would give the gear some room to shrink without splitting. On the other
hand it seems with so many types of plastic, nylon teflon etc. they
could find something suitable. jerry
