Check con-rod bearing clearance (with micrometer
gauge and internal measuring device)
Measure
| 1. |
Attach inner plunger and calibrate with micrometer gauge
(1)
|
| 2. |
Mount con-rod bearing cover on con-rod
| • |
Tighten 2x bolt 35 Nm + 45° +
15°

| • |
Measure at points I, II and III with internal measuring
device
|
|
|
|
| 4. |
Work out average con-rod diameter
| • |
Formula: I + II + III / 3
