Dave Stubbs Posted October 7, 2017 Share Posted October 7, 2017 Hi everyone, New to the forum and G scale and so far having a blast. I model Z scale for the past 10-15 years so loving the big scale? I bought a brand new MTH challenger last week and when I got it all the traction tires have liquefied. they left big black puddles on the track I set it on. I know this has been on the shelf for a very long time but still surprised how bad it is. Anyhoo no time like the present to dig into it and put in the new proto 3.o board. While I have it apart any other suggestions to up grade? Also does anyone know what part number for the tires when I looked it said they don't have a exploded view and gave me a choice of 6-7 different ones. thanks in advance for any ideas or advice. I'll keep searching forums for ideas. Thanks, Dave Quote Link to comment Share on other sites More sharing options...
Rayman4449 Posted October 7, 2017 Share Posted October 7, 2017 Hi Dave welcome. On the traction tires, you got one that had a bad batch of rubber so you will just need to clean the drivers up with alcohol and install the new ones. Have to remember that if the engine is probably 13 years old so the tires with bad compound have had a long time to deteriorate. In contrast, my original first run challenger still has its original tires so they will last a long time if they have the right compound. I keep these tires and wide variety of other MTH One gauge/O gauge parts in-stock so just send me an email. As far as other modifications, for the Challenger I recommend adding weight and a front suspension to eliminate the front driver set from slipping under load: http://www.rayman4449.com/MTH_Challenger_mods.htm#Reduce_front_driver_wheel_slippage Enjoy Quote Link to comment Share on other sites More sharing options...
Dave Stubbs Posted October 7, 2017 Author Share Posted October 7, 2017 Hi Ray, Was going to call you tomorrow to ask and also order an up graded speaker. working on the tear down right now and will add the weight up in front under the porch. I'll send an e mail with my requests to make it official. Quote Link to comment Share on other sites More sharing options...
du-bousquetaire Posted April 29, 2018 Share Posted April 29, 2018 By the way don't use meth on rubber it will soften it and disolve it. I found out with live steam as once (a long long time ago), i used a rubber tube for the meth! It is possible that steam oil has a bad effect on the rubber on traction tyres. but all my other MTH engines don't have any issue with the rubber tyres.

Nickatnite Posted June 5, 2019 Share Posted June 5, 2019 Hi, new to this forum. I too had problems with my traction tires melting. I've bought 3 used MTH Hudsons and they all had melted tires. Even the spare sets were bad. What a mess to clean ! I had never experienced this before, with all the MTH engines I've bought over the years.

Rayman4449 Posted June 5, 2019 Share Posted June 5, 2019 Same issue as I described above and cleans up easily with rubbing alcohol. Of all the engines I have bought for my personal collection none have had that problem. Only some that had bad batch of rubber. Quote Link to comment Share on other sites More sharing options...
Jerry B44 Posted June 12, 2019 Share Posted June 12, 2019 I had that problem years ago. Not since. Quote Link to comment Share on other sites More sharing options...
