Piston: Service and Repair

INSTALLATION


Note: Before installing piston, apply a coat of engine oil to ring grooves and cylinder bores.


1. If crankshaft is already installed:

- Remove connecting rod caps, then slip short sections of rubber hose over the threaded ends of connecting rod bolts.
- Install ring compressor, check that bearing is securely in place, then position piston in cylinder and drive in using the wooden handle of a hammer.
- Stop after ring compressor pops free and check connecting rod-to-crank journal alignment before driving rod into place.
- Install rod caps with bearings, and torque nuts to 29 N.m (21 lb-ft).

2. If crankshaft is not installed:

- Remove rod caps and bearings, install ring compressor, then position piston in cylinder and drive in using the wooden handle of a hammer.





- Position all pistons at top dead center.

Note: Maintain downward force on ring compressor to prevent rings from expanding before entering in cylinder bore.
