We removed the locking pins and the denso motors worked much better in this steering application. Even with the pins removed, we had random motor shut down. We removed the jags and substituted victors. Since we went to victors we have not had any problems with the Denso units. Denso and jags do not mix. The over all design has worked very well. However we are working on several design tweeks in the off season. One thing that gave us problem were set screws constantly loosening. The next iteration will not rely on sets screws.

You could definitely get away with #25 chain on the initial reduction, and possibly on the final reduction as well.
