Pittman 8x13 vs 8x23

Get me the full part numbers and I’ll look in the Charlie Pittman book of wonders for the specs…..only hiccup if they’re custom runs for a specific customer, and not listed in the suffix options….this is just a sample, ….

The 8x13 12v Pittman: stall torque 6.76 oz-in and 8238 no load rpm.

the 8x23 12v Pittman’s stall torque 10.5 oz-in and  no load rpm 8070.

For outstanding slow starts under load on grades torque counts.  My preferred motor where space allows is a Pittman 9x33 with stall torque 31.6 oz-in and  5993 rpm.  I installed them in PRR 4-8-2’s.  In PRR 2-10-4's I installed the longer Pittman 9x34 motors with 41.3 stall torque and 6151 rpm.

8xxx series motors are 1 1/4" diameter, 9xxx series motors are 1 5/8" diameter.      My source for the data is an old Bob Janzen re-motoring sales brochure.

Hope this helps.

Ed, you it the nail on its head.  Many thanks.

Thanks also to Harmonyards.

Cheers,

Ed

I have the entire 2007 Pittman Motor catalog (4 megabytes). I will email it to anyone wanting a copy.  Just send me a message.

Jim,

I can't find your email address in your profile.  My email address is in my profile so please send the Pittman catalog to me.

Thanks,

Ed

Jim,

Please send a copy to me as well.  My e-mail address is in my profile.

Thanks!

Bob and Ed Kelly the catalog has been emailed.  I've corrected the lack of email address in my profile.

Last time I needed a Pittman motor I couldn't find a source. Where are these motors available beyond the used stuff on Ebay or perhaps off a train show table?

Thank you

Bob

Jim,

Thank you.

BTW, my NCE radio system has worked flawlessly for over 15 years.  Great product!

Regards,

Ed

Bob,

Great question!  I look forward to the answer.

Ed

Did you try calling Pittman?  New motors are not cheap any more.

We used to be able to call Pittman themselves, sometimes Charlie himself would even answer the phone, ….Charlie was a traction guy himself, so conversations with him, and placing orders were easy and enjoyable,…then Pittman got picked up by Hayden, still could call in orders, but much colder, and harder to get an order together, and unless you were buying a large lot of off the shelf models, it was slow going,….although Hayden always came through…….then enter Ametek…..Ametek really ain’t interested in the hobby segment anymore,….AMOF, they don’t period,…..aerospace and medical is their real only interest …….yes, you can buy from Ametek, but the quantities and the prices make it totally unfeasible …….I believe Ametek has even gotten out of the elevator door motor business, which was Charlie’s and then Hayden’s primary source of sales…..(according to them) ……..most of us have gone underground, finding motors second hand, where ever possible …..stock up when you find them….

What’s even worse fellas, Ametek has moved a good portion of production overseas,……🤮….Pittmans made in China …..who’d a thunk that?..

P&D hobbies used to stock Pittman's    They were the 8xxx series and had ball bearings.    I dont' know if they still do, but they have a website.    I think the last time I looked the price was about $65.    These were new, not used.

I just checked the P&D Hobbies website.    They still list the Pittman motors in stock for 60.    Under O scale drive components / P&D Weaver

Bad news for a multitude of reasons.  Did that second package of parts arrive OK?

Hi All,

I tried McMasterCarr and they did not carry the Pittman 8423.

Does anyone know a source for this motor?  Actually, any 8x23 motor will do.

Thanks,

Ed
