7. After installing a new set of rings, measure the
ring-to-groove clearances:
8. Rotate the rings in their grooves to make sure they do not bind.
9. Position the ring end gaps as shown: 1. Set the crankshaft to bottom dead center (BDC) for
each cylinder as its piston is installed.
2. Remove the connecting rod caps, then install the ring compressor. Check that the bearing is securely
in place.
3. Apply new engine oil to the piston, inside of the ring compressor, and the cylinder bore, then attach
the ring compressor to the piston/connecting rod
assembly.
4. Position the mark (A) to face the cam chain side of the engine block.
5. Position the piston/connecting rod assembly in the cylinder, and tap it in using the wooden handle of a
hammer (A).
Push down on the ring compressor (B) to prevent
the rings from expanding before entering the
cylinder bore.
6. Stop after the ring compressor pops free, and check the connecting rod-to-rod journal alignment
before pushing the piston into place.

17. Install the main bearings, then put the lower block
on the engine block.
18. Apply new engine oil to the threads of the bearing cap bolts.
19. Tighten the bearing cap bolts, in sequence, to 29 N·m (3.0 kgf·m, 22 lbf·ft).
20. Tighten the bearing cap bolts an additional 56 °. 21. Tighten the 8 mm bolts, in sequence, to 22 N·m
(2.2 kgf·m, 16 lbf·ft).
22. Apply a light coat of new engine oil around the crankshaft oil seal.
23. Apply a light coat of new engine oil to the crankshaft and the lip of the crankshaft oil seal.
24. Use the driver and the oil seal driver attachment 96 to drive a new oil seal squarely into the engine
