MAIN BEARINGS AND CONNECTING ROD BEARINGS
Visually inspect each bearing for peeling, melt, seizure and improper contact. Replace the faulty bearings.
OIL CLEARANCE MEASUREMENT
To check the oil clearance, measure the outside diameter of crankshaft journal and crank pin and the inside diameter of bearing. The clearance can be
obtained by calculating the difference between the measured outside and inside diameters.
Oil clearance:
Crankshaft main bearing
0.02-0.05 mm (.0008- .0019 in.)
Connecting rod bearing
0.02-0.05 mm (.0008- .0019 in.)
Limit:
Crankshaft main bearing
0.1 mm (.004 in.)
Connecting rod bearing
0.1 mm (.004 in.)
PLASTIC-GAUGE METHOD
Plastic-Gauge may be used to measure the clearance.
(1) Remove oil and grease and any other dirt from bearings and journals.
(2) Cut Plastic-Gauge to the same length as the width of the bearing and place it in parallel with the journal, off oil holes.
(3) Install the crankshaft, bearings and caps and tighten them to the specified torques. During this operation, do NOT turn the crankshaft. Remove the
caps. Measure the width of the Plastic-Gauge at the widest part by using a scale printed on the Plastic-Gauge sleeve.
