Installation

PROCEDURE

1. Install the expander.
2. Install the upper side rail. To install the side rail, first place one end of the side rail between the piston ring groove wall and the expander, press it in, then, pressing around the circumference, install it into the piston ring groove.

Do not use pliers to spread the piston rings when installing the side rail.

3. In the same way, install the lower side rail.
4. Using piston ring expander pliers, install the No. 2 compression ring.

5. Using piston ring expander pliers, install the No. 1 compression ring.
6. Apply a thin coat of engine oil to the piston and piston rings.

7. Position the piston ring end gaps as shown in the illustration.
8. Using a special tool, compress the piston rings onto the piston.
9. Install the piston with the piston rings into the No. 1 cylinder, with the mark on the piston facing the front of the cylinder block.
10. Using the handle of a hammer, tap the piston into the cylinder so that the big end of the connecting rod seats on the crankshaft journal.
11. Install the connecting rod bearing insert into the connecting rod cap.

12. Install the connecting rod cap and tighten the nuts.
Torque: 32–35 N·m

13. Using a feeler gauge inserted between the connecting rod and the crankshaft, measure the connecting rod side clearance.
Standard connecting rod side clearance: 0.10–0.25 mm
Maximum allowable clearance: 0.40 mm
