Repair Procedures: Reassembly
- Thoroughly clean all parts to be assembled.
- Before installing the parts, apply fresh engine oil to all sliding and rotating surfaces.
- Replace all gaskets, O-rings and oil seals with new parts.
- Assemble the piston and the connecting rod.
- Install the snap ring (A) in one side of the piston pin hole.
- Align the piston front mark and the connecting rod front mark.
- Insert the piston pin (B) into the piston pin hole and the small end bore of connecting rod.
- Install the snap ring (C) in the other side after inserting the piston pin.
NOTE: Apply a sufficient amount of engine oil to outer surface of the piston, inner surface of piston pin hole and small end bore of the connecting rod before inserting the piston pin.CAUTION:- Be careful not to damage and scratch the small end bore, piston pin hole and piston pin when inserting the piston pin.
- Set the snap ring firmly so that the snap ring can contact with the whole groove of the piston pin hole.
- Install the piston rings.
- Install the oil ring spacer and 2 side rails by hand.
- Using a piston ring expander, install the 2 compression rings with the maker mark facing upward.
- Position the piston rings so that the ring ends are as shown. (The No. 1 ring should be on the opposite side of the No. 2 ring.)
Example)
CAUTION: Check to ensure that the oil ring can be turned smoothly. - Install the connecting rod bearings.
- Align the bearing claw with the groove of the connecting rod or connecting rod cap.
- Install the bearings (A) in the connecting rod and connecting rod cap (B).
CAUTION: Be careful not to change the position of bearing caps. - Install the crankshaft main bearings.NOTE: Upper bearings have an oil groove of oil holes; Lower bearings do not.
- Align the bearing claw with the groove of the cylinder block, and push in the 5 upper bearings (A).
- Align the bearing claw with the groove of the lower crankcase (B), and push in the 5 lower bearings (A).
- Install the thrust bearings.
Install the 2 thrust bearings (A) on both sides of the No. 3 journal of the cylinder block with the oil groove facing out.
- Place the crankshaft (A) on the cylinder block.
- Apply liquid sealant on the top surface of the lower crankcase.
- Using a gasket scraper, remove all the old packing material from the gasket surfaces.
- The sealant locations on the lower crankcase and the cylinder block must be free of harmful foreign materials, oil, dust and moisture. Spraying cleaner on the surface and wiping with a clean duster.
- Assemble a new rubber gasket (A) on the top of lower crankcase.
- Apply liquid sealant on the bottom of the cylinder block. Continuous bead of sealant should be applied to prevent any path from oil leakage.
Bead width: 2.5 ~ 3.5 mm (0.10 ~ 0.14 in.)
Sealant: Threebond 1217H or equivalent
CAUTION:- Assemble the lower crankcase within 5 minutes after applying sealant.
- The engine running or pressure test should not be performed within 30 minutes after assembling the lower crankcase.
- Excess sealant on application surface of sealant of following process should be removed before hardening.
- If the sealant is applied to the top surface of the lower crankcase, it should be the same position as the cylinder block.
- To prevent leakage of oil, apply sealant gasket on the inner threads of the bolt holes.
- Place the lower crankcase on the cylinder block.
- Install the main bearing cap bolts.
Using SST (09221-4A000), install and tighten the 10 main bearing cap bolts, in several passes, in the sequence as shown.
Tightening torque
1st step:
27.5 ~ 31.4 N.m (2.8 ~ 3.2 kgf.m, 20.3 ~ 23.1 lb-ft)
2nd step: 120 ~ 125°
CAUTION:- Do not reuse the bearing cap bolts.
- Do not apply engine oil on the bolt threads to achieve correct toruqe.
NOTE:- The main bearing cap bolts are tightened in 2 progressive steps.
- If any of the bearing cap bolts is broken or deformed, replace it.
- Be sure to assemble the main bearing cap bolts in correct order.
- Install the lower crankcase bolts, in several passes, in sequence as shown.
Tightening torque:
18.6 ~23.5 N.m (1.9 ~ 2.4 kgf.m, 13.7 ~ 17.4 lb-ft)
Check that the crankshaft turns smoothly.
- Check the crankshaft end play.
- Install the piston and connecting rod assemblies.NOTE:
- Before installing the piston, apply a coat of engine oil to the ring grooves and cylinder bores.
- Install the piston and connecting rod assembly with the front marks facing the front of the engine.
- Install the ring compressor, check that the rings are securely in place, and then position the piston in the cylinder, and tap it in using the wooden handle of a hammer.
- Stop after the ring compressor pops free, and check the connecting rod-to-crank journal alignment before pushing the piston into place.
- Apply engine oil to the bolt threads. Install the rod caps with bearings, and tighten the bolts.
Tightening torque
1st step:
17.7 ~ 21.6 Nm (1.8 ~ 2.2 kgf.m, 13.0 ~ 15.9 lb-ft)
2nd step: 88 ~ 92°
CAUTION: Do not reuse the connecting rod cap bolts.NOTE:- Using the SST (09221-4A000), tighten the bolts.
- Maintain downward force on the ring compressor to prevent the rings from expending before entering the cylinder bore.
- Check the connecting rod end play.
- Install a new rear oil seal.
- Apply engine oil to a new oil seal lip.
- Using SST (09231-H1100, 09214-2E000) and a hammer, tap in the oil seal (A) until the rear oil seal face is aligned with the cylinder block assembly rear face.
