MAXIMUM TOOL TO TOOL BUSHING CLEARANCE
Step 3
Measure the inside diameter of the lower and upper tool bushings. 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.

GH07 1.87 (47.4) 2.07 (52.6)
GH1 2.26 (57.4) 2.46 (62.6)
GH2 / GHS2 2.61 (66.4) 2.82 (71.6)
GH3 3.01 (76.4) 3.21 (81.6)
GH4 3.40 (86.4) 3.61 (91.6)
GH6 4.19 (106.4) 4.55 (115.6)
Step 4
Compare the tool and bushings 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. Obviously, replacing both the tool and bushings would bring
the clearance back to new.
