If not already marked, match-mark the rod and cap on the tang side with the cylinder number from where they were removed. Changing the position of the ring in relation to the cylinder can disrupt the wear patten causing premature wear of the cylinder and ring. Even if you could just get the connecting rod I would not. Installation of Piston and Connecting Rod Assembly To install the piston and connecting rod assembly to the engine except 14L and 12. Otherwise, assembly may be impossible. Before loading the piston into the liner, turn the connecting rod so that the bearing end is offset approximately 1015 degrees and not perpendicular to the crankshaft, as is the case with cast iron pistons. Note: Do not allow the piston to slide out of the bottom of the ring compressor.
If not already marked, match-mark the rod and cap on the tang side with the cylinder number from where they were removed. . Piston pin bolts are considered one-time use items and must be replaced with new bolts when removed for any reason. Note: If removing the piston and connecting rod assembly to work on the cylinder liner, stop here. Remove the piston and the cylinder.
The guides also prevent the connecting rod from contacting the liner and damaging the surface. Note: It is not necessary to torque the bolts. No other bolts or spacers may be used. Remove the 14L and 12. Install piston pin into the pin bores through rod until it rests against the previously installed snap ring. Apply a tightening torque of 60 Nm 44 lbft to the installation tool center bolt. Nicks or burrs on the inside diameter of the ring compressor may result in damage to the piston rings.
Note: Coolant system maintenance is very important. Piston pin bolts are considered one-use items and must be replaced with new bolts when removed for any reason. This will prevent damaging or jamming the Connecting Rod when the piston is pushed inside the Cylinder Block. Disassembly of Piston and Connecting Rod Assembly Piston assembly components should be segregated by cylinder and match-marked during disassembly to ensure they are assembled in the same position and orientation. Connecting Rod Guides Installation Note: The connecting rod guides are threaded at the upper end and attach to the rod bolts. Note: Coolant system maintenance is very important.
The number on the cap and rod should be on the same oil cooler side. Repair or Replacement of Piston and Connecting Rod To determine if repair is possible or replacement is necessary, perform the following procedure. To avoid this situation, always check the part number on the end of the existing piston pin or measure the piston pin I. Bleed off all the air from the system and top off. Note: It is not necessary to remove the oil pump on 1991 and later model year engines. Considerable force on the dome could scratch or otherwise damage the inside of the cylinder liner. These orientation lugs face the front of the engine.
Connecting Rod and Cap Identification Note: When removed, the bearing cap and the bearing shell must be reinstalled on the original connecting rod before another connecting rod bearing cap is removed. The specifications on reusing piston assembly components are and. Note: For forged steel one piece piston assemblies skip to. Positioning of Piston Dome Note: If piston is a one piece forged steel piston assembly proceed to step 5. Push by hand until resistance is felt. Connecting Rod Indexing Note: There are orientation lugs cast into one side of the upper and lower sections of the connecting rod.
Note: The piston pin may feel considerably tighter than with conventional designs and possibly may not be turned easily by hand. Then the new Cylinder Sleeve can be pressed in with your hands. The Piston Compression Rings should now be fully compressed. Allow the Piston to rest on the Cylinder Block, then tighten the piston ring compressor by turning the lever in a clockwise direction until it is snug around all sides of the piston. If there is no clearance, check for proper bearing cap installation.
Information regarding 14L and steel cylinder kits will follow cast iron procedures when different. Replacing this kit you would need a Screwdriver and a Wrench. Be sure to lubricate the compression and the cylinder bore with a small amount of engine oil before attempting to push the piston into the cylinder. The numbers on the side of the connecting rod and cap identify the rod with the cap and indicate the particular cylinder in which they are used. Install the new piston and cylinder. Note: Be sure the connecting rod bolts have not been unseated or turned and the bearing locating tang is in its proper location.
