    HI,

    After seeing the thread about swapping the Fox Valley wheels on the IM AC-12, I was wondering if the same thing could be done on the CC GS-4?

    Has anyone tried this yet?

    With the CC GS-4 you can easily adjust the spring under the front truck. There is no problem with the rear truck.

    The reason I am thinking about this is that the wheels on the leading and trailing trucks are out of gauge. It is not that there is any other problem. Plus, I think the FVM wheels will look a lot better.

    I was just wondering because I thought it may be easier and look better to swap out the wheels than to try truing the gauge on the existing wheels.

    Wish I had an answer to your question perhaps another member has tried switching the trucks.

    Below is a photo of a Kato GS-4, followed by a Keys Import GS-4 and lastly the CC GS-4. To improve the looks of the CC GS-4 and Key Imports GS-4 all you have to do is apply some Neolube# 2 on the wheel sets. The front truck wheel sets can easily be put back in gauge.

    You don't have to switch out the trucks. It isn't necessary. The wheel sets can easily be put back in gauge. So swapping out the wheel sets isn't necessary either.

    The wheel sets on the AC-12 were swapped out by some users who had code 55 track. The original wheel sets were hitting the spike heads.

    Hi Bob,

    Here is what I found, two of the wheels are over gauge. It is easy to fix under gauge wheels, but I am not sure how to compress the over gauge wheels without warping the axles.

    So I will order several different sizes of FVM wheels and see which ones work the best.

    Below is a closeup of the rear truck and cab area of the CC GS-4. The rear truck look very acceptable to me.

    It was nice of you to provide further information on the CC trucks. Perhaps you have some instructions to relay to David on the fine points of adjusting the trucks to improve the Gauge.

    If you feel you would warp the axles of the front truck, by all means try to change out the wheel sets.

    If David has never adjusted over gauge wheel sets on the front or rear trucks of a locomotive, it might be wiser to try changing out the overgauge wheel sets with FVM wheel sets if they fit.

    Thanks for clarifying that, I thought you might perhaps already had created a tutorial on out of gauge wheels sets on CC or other locomotives lying around that we all could learn from.

    David

    Perhaps someone else might chime in ( I will Put The Word Out) if not and you do decide to change the Trucks to FVM as you indicated, I hope you will consider posting the steps in this thread so that our members can learn from your experience.

    I don't have a pictorial tutorial of correcting overgauge locomotive wheel sets. A tutorial with pictures is the best way to explain this procedure to a modeler who's never done this technique before especially in the CC GS-4.

    Well thanks again for that further clarification.

    I'm at a loss - which wheels are being referred to here? It's not clear from beginning to end.
    If it's the tender, then what is the prototype wheel diameter? The CC wheelsets would likely have a .563" axle length so it's a matter of 33" or 36" if applicable.

    I am talking about replacing the wheels on the front truck because they are over sized in gauge. And my thought was, why not do what was done on the AC-12 and replace the tender and trailing truck wheels too.

    I guess it will be 36" wheels on the tender, 36"on the trailing truck and 33" on the leading truck, unless there is a better way to go.

    The leading truck is an inside bearing design so the usual method of wheel replacement will have the needle points in plain view. It may be a simple removal of the points but keep in mind the axle diameter since this is what will be running in the truck frame.

    If it doesn't work out, and the flange depth is the issue, maybe contact Trainworx and enquire if their wheel turning service is still available.
