- When the connecting rod cap is installed, make sure that the cylinder numbers, marked on rod end cap at disassembly, match. When a new connecting rod is installed, make sure that the notches holding the bearing in place are on the same side.
- Replace the connecting rod if it is damaged at either end of the thrust faces. If it has a wear, or if the surface of the inside diameter of the small end is severely rough, replace the rod.

- Install the expander.
- Install the upper side rail. To install the side rail, first put one end of the side rail between the piston ring groove and spacer, hold it firmly, and press down with finger on the portion to be inserted into the groove. (Scheme 111) CAUTION: Do not use a piston ring expander when installing the side rail.
- Install the lower side rail by the same procedure described above.
- Apply engine oil around the piston and piston grooves.
- Using a piston ring expander, install the No. 2 piston ring.
- Install the No. 1 piston ring.
- Position each piston ring end gap as far away from its neighboring gaps as possible. Make sure that the gaps are not positioned in the thrust and pin directions.
- Hold the piston rings firmly with a piston ring compressor as they are inserted into cylinder.
- Install the upper connecting rod bearings into the connecting rod.
- Install the lower connecting rod bearings into the connecting rod bearing caps.
- Make sure that the front mark of the piston and the front mark (identification mark) of the connecting rod are directed toward the front of the engine.
- When the connecting rod cap is installed, make sure that any cylinder numbers placed on the rod and cap at disassembly match.
- When a new connecting rod is installed, make sure that the notches for holding the bearing in place are on the same side.
- When assembling, bolts should be fastened using the following technique. Apply oil to the threads and matching areas. Tighten the connecting rod bolt. Connecting rod bolt, tightening torque: 35 N.m + 92° (350 kg.cm + 92°, 26 lb.ft + 92°) CAUTION: After removing the connecting rod bolt, do not use it again. When using a new bolt, do not tighten the bolt more than 3 times.
- Check the bearing clearance as follows: Remove oil and dirt from the bearings and journals. Cut plastigauge to the same length as the width of the bearing and place it in parallel with the journal, avoiding the oil holes. Install the bearing and cap. Tighten to the specified torque. During this operation, do NOT turn the crankshaft. Remove the cap, measure at the widest part by using the scale printed on the plastigauge package. Connecting rod cap bearing clearance, standard value:0.022-0.040 mm (0.0009-0.0016 in). Limit: 0.1 mm (0.0039 in)
- Check the connecting rod side clearance. Connecting rod side clearance, standard: 0.10-0.25 mm (0.0039-0.0098 in.) Limit: 0.4 mm (0.0157 in.)

DISASSEMBLY
- Remove the timing belt, cylinder head assembly, drive plate, transaxle mounting plate oil pan. See «TIMING SYSTEM»(ref-159249-S10433538892004120200000) .
- Remove the oil seal case and the rear oil seal.
- Remove the connecting rod caps. NOTE: Mark the main bearing caps to reassemble in the original position and direction.
- Remove the main bearing caps and remove the crankshaft. Keep the bearings in order by cap number.

- Check the crankshaft journals and pins for damage, uneven wear and cracks. Also check the oil holes for restrictions. Repair or replace any defective part.
- Inspect for out-of-roundness and taper of the crankshaft journal and pin.
