HOW TO SELECT PISTON AND BEARING
In grinding crankshaft pin to u
se undersize bearings, keep the
fillet R (A) [0.8 - 1.2 mm (0.031 - 0.047 in)].
Main BearingINFOID:0000000005930973
HOW TO SELECT MAIN BEARING
When New Cylinder Block and Crankshaft Are Used
1. “Main Bearing Selection Table” rows correspond to main bearing housing grade on left side of cylinder block.
• If there is a corrected stamp mark (B) on cylinder block, use itas a correct reference.
2. Apply main journal diameter grade stamped on crankshaft front side to column in the “Main Bearing Selection Table”.
3. Read the symbol at the cross point of selected ro w and column in the “Main Bearing Selection Table”.
4. Apply the symbol obtained to the “Main Bearing Grade Table” to select main bearing. NOTE:
Service part is available as a set of both upper and lower.
When Cylinder Block and Crankshaft Are Reused
1. Measure the dimensions of the cylinder block ma in bearing housing inner diameter and crankshaft main
journal diameter individually. Refer to EM-97, "
Inspection".
2. Apply the measured dimension to the “Main Bearing Selection Table”.
3. Read the symbol at the cross point of selected ro w and column in the “Main Bearing Selection Table”.
4. Apply the symbol obtained to the “Main Bearing Grade Table” to select main bearing. Bearing undersize table:
Refer to EM-119, "
Connecting Rod Bearing".

INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
Fluids and Lubricants".
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
• Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration. Tool number WS39930000 ( – )
