1. Inspect all piston surfaces for nicks and scuffs.
2. Inspect piston and ring grooves for wear.

1. Fit the piston onto the connecting rod (3).
2. Press in the piston pin (1).
3. Install the snap rings (2).
4. Replace the piston rings as required. See «REMOVAL»(ref-306563-S12985905212008121700000) .
5. Load the piston/connecting rod assembly (1) into a ring compressor (2) with light oil lubrication.
6. Drive the piston into the cylinder using a wooden drift and a mallet. NOTE: The connecting rod bearing shell with the oil drilling (2) must be installed in the connecting rod, otherwise the connecting rod bearings will not be lubricated. The anti-twist locks of the connecting rod bearing shells must be located in the slots (1) of the connecting rods and the connecting rod bearing caps.
7. Align the connecting rod caps with the marks (1).
8. Install the connecting rod bolts.
9. Tighten the connecting rod bolts in three stages. Stage one, 5 N.m (44 in. lbs.) Stage two, 25 N.m (18 ft. lbs.) Stage three, rotate bolts 90° clockwise.
10. Test the engine for ease of rotation.
11. Install the timing chain. See «INSTALLATION»(ref-306563-S34110069372008121700000) .

1. Remove the pistons and connecting rods. See «REMOVAL»(ref-306563-S14659348812008121700000) . CAUTION: Do not remove the oil scraper ring with the pliers. The oil scraper ring must be removed and installed by hand.
2. Using piston ring pliers, remove the piston rings. CAUTION: Do not cut or scratch pistons while cleaning.
3. Use a ring grove cleaner or a broken ring to remove deposits in the ring grooves.
4. Inspect the pistons for heat scoring and distortion at the piston pin openings and piston skirts. Replace as required.

1. Measure the end gap (1) with rings at the bottom of the cylinder. Ring # 1 clearance is .20 mm (.007 in.) to .35 mm (.013 in.). Ring # 2 clearance is .20 mm (.007 in.) to .40 mm (.015 in.).
2. Measure the vertical clearance (2) of the piston rings (1).
3. Ring # 1 clearance is .012 mm (.0004 in.) to .060 mm (.002 in.).
4. Ring # 2 clearance is .010 mm (.0003 in.) to .030 mm (.001 in.).
5. Install the rings on the pistons as shown in the illustration. Compression ring (1) Sealing ring (2) Oil Ring Rail (3) Oil Ring Expander (4)
6. The ring gaps when installed must be positioned as shown in the illustration. Ring one (1) Upper side rail (2) Ring two and spacer expander (3) Lower side rail (4)
7. Install the pistons and connecting rods. See «INSTALLATION»(ref-306563-S22447334572008121700000) .

Thirty-degree offset crank pins on the crankshaft provide even, 120-degree, firing intervals for smooth operation. The crankshaft with these split pins has ample strength without adding material between the pins, keeping the engine compact and reducing weight.
