Restoring Trike sportster question

Patskih2o Fri Apr 08, 2022 5:46 pm

Hi, newbie here, just bought a trike like a I had as a kid and was wondering if anyone knows how to remove the rear wheels so I can take it apart and clean it and see if i can get it running. It looks like they may just pull off but there is a small nut on the plastic rim and it appears to be plastic so not sure if I have to take them off. Any help would be greatly appreciated, thanks!

The parts view can be found in "instruction sheets" link on the left of this page under "Cox parts catalogs". This is from year 74.
This does not show much but looks like axle might be treaded. I have never had this model in my hand but all others have a nut on the end of the axle. Some had one side reverse thread. The only exception was the Mercedes racer, it had C clips.

The nut is not plastic. Go slow and use the proper tools. The plans posted are a good guide as to what is going on in that wheel.

The trike doesn’t come up very much on here. Pictures of your problem are helpful. Apart from Cox engines a lot of members have tech, mechanical and engineering backgrounds. I say all that because anything can be solved with Cox products on here. Somebody has seen it, or we know someone who has.

Thanks guys, the picture helps but still a little baffled on how these come off as it doesn’t look like it is actually threaded. It does look like some sort of clip but in looking at the actually trike I do not see where they would be…. Huh...

Well got my curiosity going so looked on eBay. The nut is fake. Left wheel slips on the grove in axle.
This seller has tires https://www.ebay.com/itm/194957161368?hash=item2d645a3398:g:4E4AAOxyCGNTMewB

That looks fantastic. A real tribute to the 70's. As much as I'm into motorcycles, this model never appealed to me. However, seeing the red flake sparkling and that tall seat and yellow letters on the tires just looks amazing.Your photo really does it justice and this would make a great candidate for Cox engine of the month.

Really nice job. You got the tire pumped up. What are your plans for it.

Patskih2o Sun Apr 10, 2022 4:56 pm

thanks for the positive comments, for now it is going on display shelf with some of my other cars (dunebuggy, chaparral, van and lotus Indy car). I grew up in the 70’s and my older 4 brothers all had these, the only one I am missing is the dragster to complete my collection and bring back some good memories.

that does Look Great !! You did a good job of restoring the Trike . Small Cox Logo

davidll1984 Mon Apr 11, 2022 5:35 pm

Look superbe i like it Good job but did this model com with the heatsink Huh...

Patskih2o Mon Apr 11, 2022 9:37 pm

@davidll1984 looks like the model I have is the “chopper trike” with the big banana seat and did not appear to come with the heat sync. The parts page picture referenced previously was called the “chopper II” and looks like the only difference was the heat sync and the sissy bar instead of the banana seat.
