Installation of a persistent half ring of a cranked shaft
1. Install the gasket into the groove in the cylinder block and the rear main bearing cap.
2. Install special tool rod (21.085) on the pad.
3. Hit the flat surface of the special tool with a wooden mallet so that the gasket properly fills the groove provided for it and does not deform. Align the ends of the gasket with the plane of the cylinder block and the cover; elements of the gasket material should not protrude above this plane. Lubricate the liners with oil grooves with engine oil and lay them in the seats of the cylinder block, paying attention that they are in the same seats in which they stood before (comply with the designations).
4. Carefully install the crankshaft onto the main bearing shells.
5. Install main bearing caps No. 2, 3, 4 and 5, and preliminarily, without side seals, bearing cap No. 1. Tighten main bearing cap bolts to 110 Nm.
6. Position the dial indicator so that its measuring tip touches the front of the crankshaft.
Check the axial clearance of the crankshaft, which should be 0.08–0.29 mm.
7. In the event of an inappropriate value of the axial clearance, the thrust half rings of the crankshaft must be replaced. There are two thicknesses to choose from: 2.30 and 2.50 mm.
Installing the side seals in the rear main bearing cap
1. Unscrew the rear main bearing cap (№1) crankshaft.
2. Fit the side seals onto the rear main bearing cap, holding them with special tool 21.085 and attach the cover to the tool.
3. Lubricate the surfaces of the side seals with engine oil and press the entire assembly against the cylinder block. Insert the rear main bearing cap bolts and tighten to 110Nm.
4. Check whether the crankshaft rotates freely in the bearings.
5. Trim the ends of the side seals so that they protrude 0.5 mm from the bottom plane of the cylinder block. Use the 0.5 mm thick metal bar supplied with the special tool.
