5. Try to insert the split tool back into the spindle taper. Hold the tool in place while sliding the dial indica-
tor back under the split tool and measure push-out. This should be 0.030"; if it is not, correct pushout by
adding or removing shims.
6. To add or remove shims, loosen the connecting bolt in the rocker arm assembly (see photo above).
Add or remove shims as needed. Shims provide pushout adjustment at a 1:2 ratio; that is, adding a
0.010" shim will increase pushout by 0.020".
NOTE: Install shims forward of the spherical washers in the assembly. Shims should
not interfere with the washers nesting.
7. Retighten the connecting bolt and recheck tool pushout. If still not correct, repeat the shimming proce-
dure to add or remove shims until push-out is equal to 0.030".
8. Reset the tool changer axis to invisible.
Adjusting Rocker Arm / Release Guide Gap
1. Use a feeler gauge or shim to check the gap between the rocker arm cam followers (two rollers) and
the release guide. This distance should be 0.040".
2. To correct this distance, adjust the rocker arm retract bolt (found on the rear of the rocker arm, under
the shim retention bolt) up or down and secure with the jam nut.
3. Recheck the gap and make adjustments as necessary until the gap measures 0.040".
Beginning at 5% rapids, command and observe a tool change. If the change completes successfully,
repeat the test at 25%, then 50%, then 100% rapids, checking each time that the tool is transferred
smoothly between the pocket and spindle.
