ST-1 thunder Tiger bearing slipping

       Remove this ad - become a site supporter!
I have the roto start set-up on the stock motor.

Everything was fine, and just about had it running.
BTW, still working on the first break-in tank.

And then the one-way slips.
It has not worked right since.
I took it off and cleaned it.
Put it back, nothing looked broke, and it still slips.

Any help here, or should I just buy a new 'one-way'.

one way bearing on st1

usually to get the rotostart backplate to fit on an st1 you have to grind down the chassis plate right behind where the motor sits to get it to fit properly.
but from the sounds of it your one way bearing in your rotostart needs to be changed out.

Try cleaning it out real good with nitro cleaner (or motor spray, brake cleaner, varsol, etc), even soak it for an hour or so. If it still slips, replace the bearing.

make sure you clean the shaft and the one way very good also make sure the one way is not backwards. If that doesn't work, it's time for a new one way. It's a new engine so i would think that would be normal since the engine still has so much compression and pinch. Tekno.

Make sure that you preheat the motor between 160 to 200.wrap the engine head with a sock or rag and try to keep the temps in that range for at least the first litre of feul.
Make sure that your motor is not flooded ...loosen the glow plug and trun it over until you it turns over easily, then tighten the plug add heat and try to restart .If the roto start battery is fresh and it's difficult to turn over the motor ,it's more than likely the motor is flooded
If you try to start the motor with out preheating our when it's flooded you WILL damage the 1 way bearing and our the conrod.There is alot of mechanical pinch in new motors.
Search this forum for break in info ...there a pill of threads on it , or contact your hobby shop and they will help you out.

hope this helps
