Caution: Do not bore or hone the cylinder bore sleeve. The cylinder bore sleeve inside diameter (I.D.) is fully machined and honed to size and is optimally finished as shipped. Any attempt to modify this factory-produced sizing and finish with additional boring and honing will lead to engine damage, excessive noise or abnormal oil consumption.
- After installing the NEW cylinder bore sleeve(s) into the engine block, trim the excess material from the cylinder bore sleeve flange.
Caution: Ensure that all the metal particles are collected in order to prevent internal damage to the engine or bearings.
- Place the EN-45680-884 metal shaving catch plug into the cylinder bore sleeve to be trimmed. Position the top approximately 3.0 mm (0.12 in) below the top surface of the cylinder bore sleeve.
- Place additional EN-45680-884 metal shaving catch plugs into all remaining cylinder bore sleeves.
Caution: Installing the metal shaving catch plug deeper than the recommended depth will create a decrease in vacuum system performance. A decrease in vacuum system performance will cause metal shavings to enter the engine and cause engine failure.
Caution: Installing the metal shaving catch plug above the recommended depth will cause damage to the metal shaving catch plug.
- Ensure that the EN-45680-884 metal shaving catch plug is 3.0 mm (0.12 in) below the top surface of the cylinder bore sleeve.
- Ensure that the correct bore trimmer pilot and chamfer bit are installed on EN-45680-861 trimmer base assembly :
| • | EN-45680-881 chamfer bit , 88 mm sleeve |
| • | EN-45680-885 trimmer pilot , 88 mm sleeve |
Note: Before using the trim tool assembly, the height of the cutting blades must be set to the proper specification. The proper specification is that the cylinder bore sleeve flange must be flush to +0.02 mm (0.0008 in) above the block deck surface.
- The groove side of the set gauge ring (1) on EN-45680-886 gauge ring assembly should be positioned upward on a flat surface.

Caution: For proper tool operation, a drill motor with a 1/2 inch chuck, 1 1/8 hp, 7 amps, triple gear reduction, and a 450-600 RPM rotational speed in a clockwise direction must be used. If the proper drill motor is not used, damage to the cylinder bore sleeve will occur.
- Fasten the EN-45680-866 drive adapter into the drill chuck.
Caution: Ensure that there are no crimps in the air feed hose or the vacuum hose. Crimps in the hose may cause metal shavings to exit the cutting tool in any direction, causing engine damage.
- Connect a compressed air supply (75-125 psi) to the male quick connect located on EN-45680-861 trim tool assembly . Turn the compressed air valve to the open position. This starts the venturi vacuum system that will catch the metal shavings.
Note: It should not take longer than 15 seconds to complete the trimming procedure. If it does, the brimming bits must be positioned to a new cutting surface.
- Place the EN-45680-866 drive adapter and the drill assembly vertically onto the drive adapter end of EN-45680-861 trim tool assembly . Do not apply downward force on the drill until full rotational speed has been reached. After reaching full rotational speed, gradually apply downward force until the cutting action is complete in approximately 5 seconds.
- Remove the EN-45680-866 drive adapter (1) and the drill assembly from the EN-45680-861 trim tool assembly .
- Turn OFF the compressed air valve.
- Remove the EN-45680-861 trim tool assembly from the engine block.
- Wipe the cylinder bore sleeve and the surrounding areas of any powder residue. Remove the EN-45680-884 metal shaving catch plug .
- Install a straight edge on the cylinder block perpendicular to the crankshaft centre line.
- Using a light, illuminate the rear side of the straight edge.
- Looking at the front of the straight edge, inspect to see if light is protruding through the bottom of the straight edge and the top of the cylinder bore sleeve flange. If light is present on either side of both sides of the cylinder bore sleeve, the cylinder bore sleeve is cut incorrectly and a new cylinder bore sleeve needs to be installed.
- Looking at the front of the straight edge, inspect to see if light is protruding through the bottom of the straight edge and the top of the cylinder block deck surface. If light is present on both sides of the cylinder block, the cylinder bore sleeve is cut correctly.
- Proceed to the next bore sleeve to be trimmed, repeating steps 10-19 if necessary.
- Install the piston and the connecting rod. Refer to
Piston, Connecting Rod, and Bearing Replacement : LE5 or LE9 .
