MAXIMUM TOOL TO TOOL BUSHING CLEARANCE
Step 3
Measure the inside diameter of the tool bushing. The maximum tool bushing inside
diameter is compared to a new tool only. If the tool bushing dimensions are at or above
the charted value, the bushing must be replaced.

Step 4
Compare the tool and bushing to the charts in Step 2 and Step 3. Choose the new
component (tool or bushing) that will bring the maximum clearance to below the value
seen in the chart of Step 1. Replacing both the tool and bushing would bring the
clearance back to new.
