I purchased this little guy for my #3 BIM Steam Engine.....very snug fit. Originally I was going to use a steel spring drive belt, but seemed the the pulley on my Fly Ball Governor (Brass) was just slipping regardless of the tension applied. I purchased a 1 7/8 x 1/16 O-ring......wow, PMR pulley and mine grabbed nice and sure........very happy with this purchase.
