Sticking Gears

1139 Views 5 Replies 3 Participants Last post by  Jimster71

I was trying to run a couple of my old porsche cars (the silver and gold ones from the old LeMans set) on a classic track I set up.

The gold car still runs fine (after cleaning/oiling) but the silver car is having trouble with the rear wheels sticking.

I opened up the car and took the rear wheels out to check the motor ran ok, which it does. It seems to be a problem between the gears that sticks.

I cleaned the teeth of both gears and they look to be in good condition. I tried the small gear at various points along the motor spindle to see how it meshed with the large gear and it appeared no different than on my other cars.

Any ideas on what the problem could be?

I was wondering if the back axle has become slightly bent, but I've not checked for that yet. I was also going to try the back axle/gears from the gold car to check that too.

Other suggestions welcome

Thanks for the comments, will try them out.

I've noticed that the old cars are slow when compared to my motogp bike, but that's fine for now as I can get some practice without the cars flying off the track so much

I was thinking of getting those cheap scaley audi tt cars, which look like they'll take a bit of crashing, while I get up to speed (excuse the pun).

On closer inspection, the pinion is indeed split at the point it was sticking.

I will pick up spares at the weekend in town.

Thanks again.
