Dimensional inspection and chamfering on Oiles Drymet LF Press-fit force Press-fit smoothly with hydralic (pressure), pneumatic pressure, or a vice. Avoid press-fit by use of impact such as use of a hammer. It might induce damage of the bushing, or change the size of the inner diameter after press-fit.

The O.D. is cheeked by "GO" and "NO GO" ring gauges. 2. The I.D.mounted in the "GO" ring gauge is checked by plug gauges. 3. The "GO" ring gauge stands for the upper limit and the "NO GO" ring gauge the lower limit of the O.D. tolerance. 4. Chamfering: Both ends of the I.D. and O.D. are chamfered as shown in the right diagram except those with the ID of 9mm or less which are not chamfered.
