After verifying the micrometer group, set micrometer for.
Place cutter in micrometer group and hold it firmly against the micrometer spindle E and surface F. Loosen set screw G on cutter and allow adjusting pin H to push out against the micrometer spindle E. While holding cutter in place, slowly allow the cutter tip to come in contact with cutter stop B. Back off micrometer thimble and recheck cutter setting. If cutter is not set correctly, repeat steps 3 and 4. Back off micrometer and remove cutter from micrometer group.
Preparing Block for Boring 1. Steam clean block. Remove all top deck dowels. Remove all burrs, rough places and high spots from the top surface of the cylinder block with a large mill cut file. Clean the top surface of the cylinder block to make it free from all foreign material. This area is used by the cutter plate to center the counter bore tool over the bore. Procedure to Machine Counterbore Feed Valve Operation To close feed valve turn valve knob to the right so pointer is horizontal figure 1.
To open feed valve, turn knob to the left so pointer is in vertical position figure 2. Helpful Hint Note the position to the feed valve in each of the following photos. NOTE: Always remove the spacer plate from the cylinder block, on those engines that have a spacer plate, before doing the counterbore procedure. NOTE: Prior to placing the boring machine on engine block, make sure that the bottom surface of base plate is clean and burr free, the cutter bit is removed from the cutter plate, and all screws are securely fastened.
Cover lower bore in cylinder block to prevent chips from falling onto crankshaft. Install cutter plate 1 on the shaft of the counter bore tool and secure with washer 2 and nut 3. Place counter bore tool over bore to be cut. Open feed valve 4 and lower the cutter plate into the bore. Push down firmly on the mainshaft while rotating the cutter plate in the bore to ensure proper alignment.
With the cutter plate centered in bore, align baseplate with three cylinder head bolt holes in the block maintaining as much baseplate-to-block contact as possible. Install washers and cap screws through baseplate and into cylinder block. Handle may be swung up for easy access to cap screw. Swing handle 5 down and lock in position. Rotate mainshaft of counterbore tool to ensure straight sided cutter plates are centered in bore.
If binding occurs, loosen head bolts and repeat steps 3 and 4. Tapered cutter plates should center by pushing firmly down on mainshaft of the counterbore tool. Tap counterbore tool side to side to center tool and visually inspect for degree contact in the bore.
NOTE: Rotating a tapered cutter plate may wear a groove into the surface of the cutter plate. Retract the cutter plate 1 from the bore and lock it in the full up position by closing the feed valve 4. Refer to "Setting Cutter for Bore Diameter" and set cutter bit. NOTE: Do not resharpen cutter bit. A resharpened or dull cutter bit loses its center line and will cause the bore to be cut incorrectly.
Insert cutter bit 6 all the way into the cutter plate 1 and tighten cutter plate swivel pad set screw. Cutter bit should enter with noticeable drag due to ball spring detent on bottom of cutter plate. The cutter bit must fully contact the main shaft of the boring tool to assure accurate boring. NOTE: The cutter bit must be inserted into the cutter plate slot with the tip to the lower left side of slot. NOTE: The cutter bit has a shallow hole which will face downward when the cutter bit is properly inserted into the cutter plate slot.
Place a 0. Open feed valve and lower cutter plate until the cutter bit rests on the feeler gauge. Tighten swivel pad set screw to secure cutter bit in place. Loosen the set screw on the depth set collar 8 and adjust the set collar up turn counterclockwise. Attach the depth set spacer 9 to the mainshaft below the depth set collar 8 and resting on the counterbore tool housing. Place the repair insert A between the depth set collar 8 and the depth set spacer 9. Lower turn clockwise depth set collar down the mainshaft so that it rests squarely on the repair insert and securely tighten the set screw in the depth set collar.
Remove the repair insert. Pull mainshaft to the full upright position and lock feed valve 4 in the closed position. Remove feeler gauge. Install universal drive adapter and drill onto driveshaft of counterbore tool and prepare to bore without stopping until the counterbore tool freewheels.
NOTE: Approximately half way through the cut, the operator should be prepared for the increased load put on the counterbore tool caused by the additional material being cut.
A firm grip and a balanced stance are recommended. Operation is complete when counterbore tool freewheels. Remove the electric drill from boring machine. Open feed valve 4 and retract cutter plate 1 to its full up position. Close feed valve 4 to lock cutter plate in the up position.
Loosen swivel pad set screw and insert tool removal hook 13 into shallow hole in bottom of cutter bit 6 and pull to remove cutter bit 6 from cutter plate 1. Measure the actual depth of cut with 9U Depth Gauge Assembly and determine the difference between the actual bore depth and the bore depth in the chart "Cutter Plate, Cutter Bit, and Machining Dimensions for Cylinder Block.
Loosen set screw of depth collar 8 and loosen depth collar 8 clockwise 1 mark for each. Remove all chips and foreign material from the cutter recess and the access areas where the cutter contacts the mainshaft.
It is very simple to clean these areas with a cotton swab. Foreign material in these areas could cause the next bore to be cut oversize. Repeat steps 13 through Remove the counterbore tool. Refer to instructions "Cylinder Liner Projection" for the appropriate engine and measure the cylinder liner projection. Cylinder Liner Projection Tools Needed Check cylinder liner projection above top of spacer block as follows: 1.
Make certain the cylinder liner flange and cylinder block are clean.
