Checking clearances between the insert and the crankshaft journals

The test is performed with a special calibrated plastic wire.

Thoroughly clean work surfaces and inserts the corresponding crankshaft journal. Put a plastic thread segment equal in length to the width of the liner to the surface of the cervix. Depending on the type of audited neck set on the neck of the connecting rod with a lid or main bearing cap and tighten the nuts or bolts. Nuts rod bolt tightening torque 2.9 kgf ?� m, bolts main bearing caps - torque 5.3 kg ?� m. Avoid while cranking the engine.

Remove the screws, remove the cover and, using a scale printed on the packaging of the wire, the deformation of the wire define backlash size.

If the bearing clearance exceeds

0.1 mm pereshlifuyte neck under the repair size and put oversize liners.
