Note

The recommended hole sizes shown in columns 4 & 5 above are required to maintain the inside diameters after the Tension Bushings are inserted as shown in columns 8 & 9. If the clearance between the Tension Bushings and the pin is not critical, greater hole tolerances are allowable and will still insure proper seating of the Tension Bushings. These tolerances are indicated in column 12 of the table. Internal chamfer available upon request.
