Atlas/Roco vintage F9 upgrade

 

         Hi Jack,

 

            I put the NWSL 2524-6 wheels on mine. These include the axle gear

    as well, which are usually cracked and need replacing. These are specifically

    for the Red Caboose GP9's and Atlas F9's.  They work great just make sure

    you clean them off before installation.

I will second that, great wheels sets that really make a difference.

All the best,

"I would like to upgrade a Atlas/Roco F9 with new wheelsets compatible with the 2 rail standards"

 

   The old versions I had came with scale wheels that just needed to be re-set to correct gauge then they ran fine.....DaveB

On the several Atlas/Roco F9's I owned the wheel flange profiles were too fat to pass a wheel check using an NMRA gauge.  As a result the F9 would

ride up when running through turnout frogs with guard rails correctly set to the NMRA spec.  At the time (1973) I was raising a young family and hobby funds were tight.  Under advice of mentor John Armstrong I simply ran the locomotive upside down in a cradle and filed the backside of the wheels with the motor running.  I checked progress with the NMRA gauge until the wheel profile fit nicely in it - not precise but it worked.  Today I'd probably just buy the NWSL geared wheel sets.

  Haha, I recently did the same thing to an N scale GP20 with large flanges. I wasn't sure the tiny thing could stand the process but it was no good to me like it was. Happily it came out of the ordeal still running and is now a nice loco for my local turn.....DaveB

Jack,

The best advice is to contact NWSL direct.  Check the NWSL website.

 

I purchased a set of NWSL P64 wheelsets for the American Models Baldwin S12 loco but they did not match the factory trucks.  I sent NWSL photos and one factory wheelset and a new offering will be available in the coming weeks...all at no extra charge.

 

MANY MANY THANKS TO ALL for your answers and your advice!

This is a great and friendly forum!

 

Now, I think I have all understood about thee wheels:

 

1. the possibility to file the wheels: that's economic and I still have done this work for a N scale locomotive like Ed and DaveB. It works well.

 

2. And the NWSL products.

 

I found 3 different references for the F9:

 

40"/115

40"/145

40"/172

 

If I've well understood 115 is the finest and 172 the largest size of wheel.

 

The 145 look good. I like.

 

I still have asked NWSL but they don't answer me. So that's the reason I ask here. This forum is a good one, I've found the answers to my questions.

 

MANY THANKS AGAIN TO ALL!!!!

 

Previously, I had a PDF list from NWSL but checking google with the reference NWSL 2524-6 I found an on-line shop on the NWSL website.

 

There is a lot of interesting things!

 

The 40"/115

 

 

 

The 40"/145 (I think it's the best choice for me)

 

 

 

 

 

 

 

 

...And the 40"/172

 

Jack,

The first two pages of the Wheelsets section of the NWSL online catalog has good information on the various wheel treads which should help you select the best replacement wheelsets for your loco and trackwork.

I used the 40/145 wheels on my Atlas F-Unit. As far as I remember I ordered from the Precision Scale Co in USA, from the UK, without any problem. Website is http://www.precisionscaleco.com/
The wheels are an easy swap over for the originals and well worth the cost.

Many thanks again.

 

I've ordered from NWSL and I found several interesting items...

 

Now, I waiting for the packet!

Today, I received my NWSL order; the wheelsets look very good.

Good to hear! I put NWSL wheelsets in my Weavers and I lave no complaints

I've changed my old Roco/Atlas wheelsets against the nice NWSL ones.

 

The difference is total: now it runs beautifully, smoothy and the look is really more realistic.

 

I advice anyone to use the NWSL wheelsets. The price is low for the fun they provide.

 

They are very good!

Hearing your good news, I am going to have to do that to a pair of C-Liners
