Connecting Rod Bearing
DESCRIPTION
| Selection points | Selection parts | Selection items | Selection methods |
|---|---|---|---|
| Between cylinder block and crankshaft | Main bearing |
Main bearing grade (bearing thickness) |
Determined by match of cylinder block bearing housing grade (inner diameter of housing) and crankshaft journal grade (outer diameter of journal) |
| Between crankshaft and connecting rod | Connecting rod bearing | Connecting rod bearing grade (bearing thickness) | Combining service grades for connecting rod big end diameter and crankshaft pin outer diameter determine connecting rod bearing selection. |
| Between piston and connecting rod | — | — | — |
-
The identification grade stamped on each part is the grade for the dimension measured in new condition. This grade cannot apply to reused parts.
-
For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the measurement with the values of each selection table.
-
For details of the measurement method of each part, the reuse standards and the selection method of the selective fitting parts, refer to the text.
WHEN NEW CONNECTING ROD AND CRANKSHAFT ARE USED
Apply connecting rod big end diameter grade stamped on connecting rod side face to the row in the “CONNECTING ROD BEARING SELECTION TABLE”.

Read the symbol at the cross point of selected row and column in the “CONNECTING ROD BEARING SELECTION TABLE”.
Apply the symbol obtained to the “CONNECTING ROD BEARING GRADE TABLE” to select connecting rod bearing.
WHEN CONNECTING ROD AND CRANKSHAFT ARE REUSED
Measure connecting rod big end diameter and crankshaft pin journal diameter. Refer to Inspection.
Correspond the measured dimension in “connecting rod big end diameter” row of “CONNECTING ROD BEARING SELECTION TABLE”.
Correspond the measured dimension in “crankshaft pin diameter” column of “CONNECTING ROD BEARING SELECTION TABLE”.
Follow step 3 and later in “WHEN NEW CONNECTING ROD AND CRANKSHAFT ARE USED”.

UNDERSIZE BEARING USAGE GUIDE
-
When the specified connecting rod bearing oil clearance is not obtained with standard size connecting rod bearings, use undersize (US) bearings.
-
When using undersize (US) bearing, measure the connecting rod bearing inner diameter with bearing installed, and grind crankshaft pin so that the connecting rod bearing oil clearance satisfies the standard.
CAUTION:
In grinding crankshaft pin to use undersize bearings, keep the fillet R
[1.5 - 1.7 mm (0.059 - 0.067 in)].
| Bearing undersize table | : Refer to Connecting Rod Bearing. |
