Pressing the crankshaft rear oil seal into the crankcase before cutting off
Crankshaft mounted in rear main bearing (the rear seal is indicated by an arrow)
Free installation of the timing chain on the crankshaft
Checking the centering of the intermediate disc
1. Place the top half of the crankshaft rear oil seal into the crankcase groove. After installation, the ends of the stuffing box should protrude 0.5 mm. Insert the oil seal with an oiled hammer handle and cut it to the required size.
2. Thoroughly clean the seats of the main bearing shells, the crankshaft journals and the back surfaces of the shells.
3. Place the upper main bearing shells in the crankcase and lubricate them with oil.
4. Lower the crankshaft onto the bearing shells.
5. Insert the lower main bearing shells into their caps and lubricate them with oil.
6. Put covers of radical bearings, insert their bolts. Make sure the oil pump mounting bolt is on the front cover.
7. Lightly tighten all main bearing cap bolts, then tighten them sequentially and finally to the specified torque.
8. Track that the cranked shaft rotated freely, and that its shift did not go beyond the established limits.
9. Place the distribution mechanism bracket on the cylinder block, install the lubrication system pressure reducing valve and tighten the plugs.
10. Set the camshaft target loosely on the crankshaft, make sure the keyway is in its groove, and tap the timing sprocket so that the chain can be put on it. If the sprocket was difficult to remove, heat it to 80°C before installation.
11. Install the intermediate plate on the rear of the cylinder block, insert and lightly tighten the bolts. Using a dial gauge, check the centering of the plate on the crankshaft, and then finally tighten the bolts.
12. Install flywheel (driving disk), front crankshaft oil seal, sprocket (asterisks) camshaft (shafts) and pistons.
