Tom (verified owner) –
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.
