Review on PowerTwist V Belt Profile Width Length Power Transmission Products by Dave Russell

I ordered this 3 liter drive belt kit to replace the belt on my new Porter Cable drill. I had about 10 inches left after installation. The instillation lasted about ten minutes. This greatly changed the smooth running of this drill. Drive belts beforehand and were sure they would fit. Every belt-driven machine should have these belts! Update Feb 2014 smooth operation.
