Is it possible to add Traction Tires...

If you can source just the 222-107 grooved wheels, no cannibalization would be needed.

Also, a 8010-123 grooved wheel can be used as well with the gear section machined/ground off, and blackened to match as desired.

WOW, thanks LOU1985.

No problem. If the locomotive doesn't have a die cast metal fuel tank you may want to find one of those as well. I have a late 90's Lionel GP9 with a Pullmor motor and Magnetraction like your locomotive. I added a die cast metal fuel tank and it'll pull 20 scale boxcars or 5 16 inch aluminum passenger cars with no problems on level, steel track.

Is it possible to add traction tires to a Lionel GP-9 (single can motor) with magna-traction? The magna-traction is dead on this loco and even if it wasn't, I'm using Atlas-O track (non steel track). Any thoughts on how to improve traction would be appreciated. Thanks. 

As Pete said, use Bull Frog Snot

It works very well, is easy to apply and isn't visually obtrusive.  WE've used it a l;ot at the HO club I belong to.  I've used it on a Lionel 1862 GHeneral that couldn't pull its own train, and now it pulls fine.

Traction tires first came out on Lionel products in 1962.

@ADCX Rob, let me take you back a bit to this post you made. My question is this: do the 222-107 undercut plain wheels, and the 8010-122 plain w/o gear wheels, and the 8010-123 undercut gear wheels all have the same inside (axle) diameter?

I’m working on an ALCO 213 project that needs some 222-107 grooved wheels, but they are not to be had anywhere. This little engine had a motor transplant in a previous life and received a 200 series Pullmor motor with two driven axles, but no traction tires or undercut wheels.

So, I found and bought some 8010-122B (the B is for blackened, per the seller) wheels. Now, these wheels are supposed to be just plain, grey, MPC era Zamac non-undercut wheels according to Lionel, and would be used opposite an 8010-123 grey, MPC era, Zamac, undercut gear wheel. But I could see in the ad photos that they were indeed blackened, and that they had traction tire grooves, or undercuts. So I bought a few to give them a try. When they arrived, I found they were blackened, and they did have the appropriate undercut, and they appeared to be new; no spline grooves on the inside diameter and no wheel wear marks.

The problem is the inside diameter is too large. The wheels wobble loosely and fall right off the splined end of the axle.

When it comes to PW diesel engines, I (perhaps naively) thought Lionel made only three different diameter axles, one was for diesels with Magnetraction (stainless steel), one for diesels with no Magnetraction (steel) and one (skinny steel) for freight cars. Further, I thought that the splined axle ends on the first two (Magnetraction and non-Magnetraction) had the same diameter - that would be logical to minimize wheel inventory..

Hence my question, do the 222-107 wheels and the 8010-122 (and 8010-123) wheels all have the same inside (axle) diameter? Or did I buy some of Lionel’s PW mistakes that found their way into the retail world?

671-21 is the swedged/swaged/knurled axle part as given in the service manual for the 222, 671-25 is the non-knurled axle, all used from 1957-up & specified for the 8010 motor. The wheels should all be the same inside diameter using the diesel architecture introduced in 1949 & 1950 shared with the 622/6220/2343, and extending well into the LTI/LLC eras.

But is no longer available from Lionel.

I've used electrical friction tape cut to the width of the wheel tread.  Cut a length equal to the diameter of the wheel x 3.14 (pi). It's self adhesive, has a rough surface , and is thin.

The last post was over a year ago, I certainly hope he has figured this out by now!

Don’t hesitate.  Timco will machine the wheels and tires for 25 per axle.  They are in GA or PA.  2 week turnaround
