Cylinder Block (Internal Parts)

CYLINDER BLOCK (INTERNAL PARTS)
1. Disassemble in the order shown in the figure, referring to Disassembly Note.
2. Assemble in the reverse order of disassembly, referring to Assembly Note.

Cylinder Block (Internal Parts):

Disassembly Note

Piston and connecting rod assembly
Before removing the piston and connecting rod assembly, inspect the following.
1) Connecting rod large end side clearance.
2) Connecting rod bearing oil clearance.

Piston pin

Caution
^ The connecting rods must be reinstalled in the same positions from which they were removed. If they are not, it can cause premature and uneven wear.

Note
^ Mark the connecting rods to show their original positions.





1. Before disassembling the piston and connecting rod, check the oscillation torque as shown. If the large end does not drop by its own weight, replace the piston or the piston pin.





2. Insert the SST into the piston pin as shown.





3. Mount the piston and connecting rod in the SST as shown.





4. Press out the piston pin.





Main bearing cap
1. Before removing the main bearing caps, measure the crankshaft end play.
2. Loosen the main bearing cap bolts in two or three steps in the order shown in the figure.
3. Remove the main bearing caps.

Crankshaft
Before removing the crankshaft, measure the main bearing oil clearances.

Assembly Note





Main bearing cap
Tighten the main bearing cap bolts in two or three steps in the order shown.

Tightening torque:
54-58 N-m (5.5-6.0 kgf-m, 40-43 ft-lbf)





Piston pin
1. Set the piston pin on the SST as shown.





2. Apply clean engine oil to the piston pin.
3. Set the stopper bolt so that dimension L is as specified.

Dimension L: 61.4 mm (2.42 in)





4. Insert the piston pin and SST assembled in step 1 into the piston and connecting rod assembly.





5. Press the piston pin into the piston and connecting rod until the SST (guide) contacts the SST (stopper bolt).
6. While inserting the piston pin, check the pressure force. If it is less than specification, replace the piston pin or the connecting rod.

Pressure force: 4.91-14.70 kN
(500-1,500 kgf, 1,100-3,300 lbf)

7. Check the oscillation torque of the connecting rod.





Piston and connecting rod assembly
1. Verify that the second ring is installed with the scraper face downward.
2. Position the end gap of each ring as shown.





3. Insert the piston and connecting rod assembly into the cylinder with the (mark facing the front of the engine.





4. Align the matching marks on the connecting rod and the connecting rod cap, install the connecting rod cap.

Tightening torque:
30-34 N-m (3.0-3.5 kgf-m, 22-25 ft-lbf)
