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. Remove the piston pin by using the SST.

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.
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. Install the piston pin clip into the clip groove in the piston.
2. Assemble the piston and the connecting rod in the direction from which they were disassembled.
3. Apply clean engine oil to the piston pin.
4. Install the piston pin from the side opposite the clip.
5. Install the piston pin until the pin contacts the clip. If the pin cannot be installed easily, heat the piston.
6. Install the second clip into the clip groove in the piston.
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. Verify that the top ring is installed with R mark (tapered side) face upward. When the ring has no mark (taper), it can be installed with either side facing upward.
3. Position the end gap of each ring as shown.





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





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

Tightening torque:
48-50 N-m (4.8-5.1 kgf-m, 35-36 ft-lbf)
