Turn the crankshaft until the bearing journals forthe pistons to be installed are at bottom center.2. Put clean engine oil on the crankshaft journalsand on the inside of the cylinder liners. Put cleanengine oil on the piston rings and connecting rodbearings.3. Move the rings on the piston until the ring open-ings are approximate y 90° apart.CAUTIONNever install the ring compressor on the pistonunless the cylinder liner is used as a guide.Damage to the piston rings can be the result.4.5.6.Put ring compressor (A) in position on the cylin-der liner. Put the connecting rod and piston inposition in the same cylinder liner from which itwas removed and into the ring compressor. Makesure the “V” mark on the piston is in alignmentwith the “V” mark on the cylinder block.Push the piston into place as the connecting rod isput into position on the crankshaft.Put clean engine oil on bearings, bolt threadsand surfaces of the nuts that make contact withthe connecting rod caps. Put caps (1) in posi-tion on the connecting rods and install the nuts.Tighten the nuts to a torque of 40 ± 4 N·m (30± 3 lb.ft.). Put a mark on each nut and the endof each bolt. Tighten the nuts 90° more.CAUTIONWhen connecting rod caps are installed, makesure the number on the side of the cap is next toand respective with the number on the side ofthe connecting rod.7. Follow the same above procedure for installationof the remainder of the pistons.end by:a) install oil panb) install cylinder head5-132
