The problem occurs when I drive the model using the angular constraint.
The tommy bar rotates OK at times but randomly changes direction.
I can't find why this is happening.
I have only run this on my computer and would like to know if this manifests on other computers any help with a solution.

It is on Inventor 2017 (not listed in the software versions).
have you try give bigger number on drive constrain ? for ex you have 360 degree then you give bigger angle like 1000 ?
Thanks for the advice Adam but I have tried that.
The strange thing is it will reverse the rotation randomly.
If possible can you run the model and see if it is OK on your system.
OK I found the problem.
I Just needed to constrain the static parts of the model.
It pulls the sprocket no problem now.
