Connecting Rods And Pistons
Use the 7M-3978 Ring Expander to remove piston rings or install piston rings.Use the 5P-3526 Piston Ring Compressor to install pistons into the cylinder block.Tighten the connecting rod nuts in the step sequence that follows:
Apply 4C-5593 Anti-Seize Compound to the threads of the bolts and the contact surfaces of the bolt head.
Tighten all nuts to the following torque. Torque for nuts ... 82 8 N m (60 6 lb ft)
Put an alignment mark on each cap and bolt.
Tighten the nuts from the mark to the following value. Angle from the mark. ... 120 5 degreesConnecting Rod Bearings
The connecting rod bearings fit tightly in the bore in the rod. If the bearing joints or backs are fretted, check the bore size. This can be an indication of wear because of a loose fit.Connecting rod bearings are available with 0.63 mm (0.025 inch) and 1.27 mm (0.050 inch) smaller inside diameter than the original size bearing. These bearings are for crankshafts that have been ground smaller than the original size.Main Bearings
Main bearings are available with a larger outside diameter than the original size bearings. These bearings are available for the cylinder blocks with the main bearing bore that is made larger than the bores' original size. The size that is available has a 0.63 mm (0.025 inch) outside diameter that is larger than the original size bearings.Cylinder Block
If the main bearing caps are installed without bearings, the bore in the block for the main bearings can be checked. Tighten the nuts that hold the caps to the torque that is shown in the Specifications. Alignment error in the bores must not be more than 0.08 mm (0.003 inch). Refer to the Special Instruction, SMHS7606 for the use of the 1P-4000 Line Boring Tool Group for the alignment of the main bearing bores. The 1P-3537 Dial Bore Gauge Group can be used to check the size of the bores. The Special Instruction, GMGO0981 is with the group.

Holding top plate to cylinder block (typical example)
(1) 3H-0465 Push Puller Plate. (2) 1P-2396 Puller plate. (3) 2F-0126 Seal. (4) Top plate.
Use the following steps to check the liner projection above the top plate.
Ensure that the top plate (4) and the cylinder liner flange are clean.
Install a new spacer plate gasket.
Install the cylinder liners in the cylinder block without seals or bands.
Use 3/4 - 16 NF bolts 76.2 mm (3.0 inch) long with two 2F-0126 Seals (3) on each bolt to hold the top plate (4) to the cylinder block. Install two bolts with seals (3) on each side of the cylinder liner. Use the following four steps to tighten the bolts. Tighten the bolts to the following torque. ... 14 N m (10 lb ft)Tighten the bolts again to the following torque. ... 35 N m (26 lb ft)Tighten the bolts again to the following torque. ... 70 N m (52 lb ft)Tighten the bolts again to the following torque. ... 95 N m (70 lb ft)Note: Install two bolts with washers on each side of each cylinder liner. Install the bolts along the complete length of the top plate. This will keep the installation and removal of the bolts and washers to a minimum as each liner is checked.
Use the following items to hold the liner down.

Use the following four steps to tighten the bolts evenly. Tighten the bolts to the following torque. ... 7 N m (62 lb in)Tighten the bolts again to the following torque. ... 20 N m (15 lb ft)Tighten the bolts again to the following torque. ... 35 N m (26 lb ft)Tighten the bolts again to the following torque. ... 70 N m (52 lb ft)The distance from the bottom edge of 8B-7548 Push Puller Tool Group (6) to the top plate must be the same on both sides of the cylinder liner.
