Piston

3. Insert the new piston ring in the groove of the piston and probe measure the clearance between the piston ring and the wall of the groove. If the clearance exceeds the limit, replace the piston.

5. Feeler gauge, measure the end gap of the piston ring.

1. Check countertops rod bearing inserts the lack of bands, scratches, localized corrosion, development and other damage. If necessary, replace the pads. If work surfaces rod bearing inserts badly damaged, check the crank pins of the crankshaft. If the crankshaft is also damaged, replace it or to reuse pereshlifuyte neck to the nearest reduced size.

2. Measure the inner diameter of the connecting rod bearing inserts and the diameter of the crankshaft journals. If the oil clearance exceeds the allowable limits, replace the pads and, if necessary, the crankshaft.

2. Align the front label and insert the piston pin. The piston pin must be a smooth entrance into the piston by pressing it by hand (at room temperature). If there is a large gap, replace the piston pin.

1. Install the piston oil ring expander and the oil ring. Pliers for a release of piston rings, set the compression ring ?��2, then set the compression ring ?��1. Make sure that the label on the piston rings are directed towards the bottom of the piston.

2. Place the piston rings, as shown in the figure.

4. The special adaptation compress piston rings on the piston. Hammer handle press the piston into the cylinder so that the bottom head of a rod was established on the crankshaft.

5. Install the connecting rod bearings into the connecting rod cap. Install the connecting rod cap and tighten the nuts. Torque: 25 N ??? m tighten on a corner 90 ?�.

Do not use more than three times the bolts of covers of rods.

6. Probe inserted between the connecting rod and the crankshaft, connecting rod, measure the backlash.
