2. Clean tool holder slot (A) before installing the cutting tool. Install cutter (1) into slot (A). Pull cutter (1) out approximately .12" (3.2) over the to face of the cylinder block, while the setting for the depth of cut is made. Tighten screw (3). Carefully loosen knob (4) to lower the boring bar until cutter (1) is against the top face of the cylinder block.3. Loosen screw (5) until adjusting nut (6) is free. Install depth gauge (7) and make an adjustment to nut (6) until it is against gauge (7). Tighten screw (5), to hold nut (6) in place.
To prevent damage to the cutting tool, never hit the cutter or let it fall. Never turn the cutter backwards while it is in contact with the cylinder block.
4. Turn knob (4) counterclockwise and lift the cutter so it is above the top face (D) of the cylinder block. Turn knob (4) clockwise to hold the toolholder in position. Loosen screw (3) and push the cutter tool into tool holder slot (A) as far as it will go, then tighten screw (#). Loosen knob (4) and lower cutter (1) until it is .06" (1.5) above the top face of the cylinder block. Tighten knob (4).5. Use a heavy duty industrial drill and adapter (8)to operate the boring tool. Remove the depth gauge and start the rough cut.6. Stop the cutter rotation immediately when adusting nut (6) is against positive stop (9). Loosen knob. (4).7. Lift the cutter out of the cylinder block and tighten knob (4) again. Loosen screw (3) and remove cutter (1) with 5P1656 Hook (10).Making The Finish Cut
1. Put master gauge (1) into micrometer fixture (2); make sure the side having the mark, UP, is on top. Make an adjustment to micrometer (2) until the micrometer stem is against the master gauge. The micrometer should then read the same as the dimension given on the side of master gauge (1). 2. Remove the master gauge and put cutter (3) into micrometer fixture (2). Make an adjustment to cutter (3) until it is the exact same size as the master gauge.
Be careful not to loosen screw (A) too fast, because the adjustment of cutter (3) has a spring load behind it and damage may be caused to the cutting edge.
3. Clean the tool holder slot carefully before installing the cutting tool. Install cutter (3) into the slot, and push the tool back into the slot as far as it will go. Tighten screw (4). Lower cutter (3) until it is .06" (1.5) above the top face of the cylinder block. Close the feed control valve by turning knob (5). Start the finish cut.4. Make the complete finish cut without stopping. Stop the cutter rotation immediately when adjusting nut (6) is against positive stop (7).5. Check
