1. Wipe the back of the new top liner and put him to bed in the head of the connecting rod bearing. Ensure that the guide tab insert was in response to the rod groove. In no case do not insert zastukivaet bed hammer. Nothing can lubricate the bearing at this stage. 2. Wipe the back of the second loose leaf and lay it in the bottom head of a rod cover. Again, make sure that the tongue was back in the groove. Do not use any grease - it is essential that the mating surfaces of the bearing and rod were absolutely clean and dry. | 3. Place the piston ring locks as shown in the illustration.
A - Castle expander oil ring B - Castle bottom section of the working oil scraper ring C - Locks top working section of the oil ring and the top compression ring D - Lock the second compres- sion-ring |
4. Tighten the screws in the bearing cap segments of suitable diameter rubber hose. 5. Lubricate the piston and piston rings with pure impellent oil. Put the piston mandrel tool for crimping rings. Leave the piston skirt projecting from the mandrel tool of approximately 6.4 mm for free-filling it into a cylinder. Rings should be flush with the crimped forming surface of the piston. 6. Rotate the crankshaft so that the crank neck first appeared in BDC position. Lubricate the motor oil of the first cylinder mirror. 7. Expanding the assembly mark in the form of a recess in the bottom of the piston forward on the engine, carefully thread the rod into the first cylinder block. Get into the cylinder of the piston skirt, tightly pressed to the surface of the block of the lower edge of the mandrel tool for crimping rings. 8. Tap the upper edge of the mandrel to ensure density pressing it to the block around the perimeter of the bottom edge.
| 9. Gently tapping the bottom of the piston hammer wooden handle, enter the piston inside the cylinder, at the same time directing the bottom head of a rod in the neck of the corresponding crank crankshaft. The piston rings can suddenly jump out of a mandrel tool, and constantly watch density pressing to her unit. Take your time, if there is any resistance, immediately stop zastukivanie piston. Find out the cause of jamming and eliminate it. | In any case, do not attempt to push the piston into the cylinder force - it can lead to mechanical damage or destruction of the piston rings! |

10. After the introduction of the connecting rod and piston assembly into the engine before final installation of the bottom head of a rod cover, check the operating clearance of the crankshaft connecting rod bearing. | 11. Cut a piece of the calibrated plastic wire measuring set Plastigage, a length slightly shorter than the width of the connecting rod bearing liner and lay it along the first crank pins, parallel to the axis of the latter. |
12. Wipe the surface of the bearing in the cover of the bottom head of a rod and set the cap on the connecting rod. Make sure that the label on the cover turned out to be rotated in the same direction as the mark on the rod. 13. Lightly grease the bottom ends of the mounting nuts clean motor oil, screw them in three stages tighten with demanded effort. | To avoid jamming the key, use the thin face head. If you have any signs of seizing the key between the nut and the connecting rod, slightly lift the head and continue tightening. Keep cranking during the execution of the procedure. |
14. Give nuts, and carefully remove the cover from the connecting rod. Try not to damage the segment flattened plastic thread. | 15. From the width of the flattened wire, measured on a scale, printed on the packaging to a collection Plastigage, define size of a working backlash in the bearing. Compare result of measurement to requirements of Specifications. |
16. If the clearance is out of range before to look for a different size inserts, check Do not get under the bed backrest embedded in the connecting rod and cap liners dirt / oil. Once again, measure the diameter of the shaft journal. Flattening of the wire from one end longer than the other indicates the presence of cervical cone (see. Section Checking the crankshaft). |
