28. Remove the connecting rod bearing cap.
29. Install the piston.
30. Rotate the crankshaft by hand and check whether it rotatessmoothly.
31. If the bearings are damaged,
- replace the oil presser relief valve. - clean the oil pump and oil filter housing carefully and
replace the hose if necessary. Notice After assembling the engine, check the camshaft timing, adjust the start of fuel injection and check the TDC sensorbracket setting.
32. Fill oil and run the engine and then check the oil pressure and oil level. Notice Install the original oil filter element and then change the engine oil and oil filter element after 1,000 - 1,500km.
27. Measure the radial clearance (L) of the connecting rod
bearing. Example) Measured value ‘J’ = 47.700mm
Measured value ‘K’ = 47.653mm
Clearance ‘L’ = 0.047mm
Radial Clearance ‘L’0.026 - 0.068mm
Notice If the clearance is out of standard, adjust the radial clearance of connecting rod bearing by replacing theconnecting rod bearing shells.
26. Measure connecting rod bearing journal diameter (K).
Notice Refer to measurement of the crankshaft bearing journal
diameter.
24. Insert the new connecting rod bearing shells into theconnecting rod and connecting rod bearing cap and tighten
the 12-sided stretch bolts (11).
25. Measure inner diameter of connecting rod bearing.
