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

i've had similar trouble with these old porshes...usually its the old style pinion that has split..the later pinions have reinforcement at one end which helps...toothed one end...circular ridge the for the could well be bent...dismantle rear axle remove wheels and roll the axle along a flat surface like a mirror or piece of glass and you'll see at a glance if its straight or not..hope that helps..these old porsches are not very fast by todayts standards..but substituting some later scalex wheels ( i use some from a from a mondeo helps bring the car closer to the track and helps running...they are also very durable
