CONNECTING ROD RADIAL CLEARANCE
Radial Clearance
0.016 - 0.051 mm
Bearing Oil Clearance (Plastigauge)
• Check the oil clearance of the connecting rods and crankshaft.
− Clean all engine oil off of the connecting rod bearing and the crankshaft journal.
− Cut the plastigauge into lengths as wide as the crankshaft journal.
− Lay the plastigauge across the crankshaft
journal.
− Carefully install the connecting rod cap.

Assembly
NOTE :
• The connecting rod bolts should NOT be reused.
• Before installing the NEW rod bolts, apply clean engine oil to the threads and under the bolt heads.
Piston and Connecting Rod
• Oil the piston rings and the side of the piston.
• Position the piston rings in the proper alignment
with the piston pin (2):
− Top Ring (1)
− Bottom Ring (3)
− Oil Control Ring (4)
• Install protective coverings over the connecting rod
bolts.
• Rotate the crankshaft journal to the lowest position.
• Use a suitable piston ring compressor to insert the
piston and connecting rod assembly into cylinder.
• Make sure the forward mark on the top of the pis-
ton is facing the front of the engine (5).
• Using a suitable tool, tap the piston and connecting rod assembly into cylinder.
NOTE :
The piston direction mark (2) should point toward the
timing belt side (1).
• Check the axial clearance of the connecting rods.
