3.1.2.5.7. Assemblage of knot a rod-finger-piston

THE GENERAL DATA

Typical order of placing of piston rings

1 – маслосъемное a ring, 2 – a second sealing ring, 3 – the top sealing ring

Piston installation in a sleeve of the cylinder by means of a special holder for piston rings

To establish the piston on the adaptation so that "drop" on its lateral surface has been turned upwards. The arrow on the piston bottom also should be directed upwards. Accordingly to establish a rod.

The sizes send a sealing ring of a cranked shaft from outside a camshaft


Assemblage

PERFORMANCE ORDER

1. To arrange a rod on a heater so that heads of rods heated up, and the bases of rods should be isolated by means of a heatproof plate or in another way; on a head of a rod as the temperature gauge to place a solder slice. 2. To include a heater food, to switch off a food when solder will begin плавиться. 3. It is necessary to expedite following actions:       – To clean a drop of solder from the first rod and to prepare a rod for installation;       – To wait a minimum of 10 seconds, and then to lift a rod and to take all knot;       – To take a shaft, and then to execute the same actions for other rods;       – To establish on each piston of a ring (fig. the Typical order of placing of piston rings see);       – To arrange at an angle 120 ° locks of rings on the piston. 4. Installation of locks маслосъемного rings should be following: the lock of each link should be from each party of a piston finger, on 30–50 mm from its both parties, the spring cut should be precisely on an axis. 5. Installations of a sealing ring (top) and sealing (second) should be such that their locks have been displaced on 120 ° concerning a spring and did not coincide. Sealing rings to establish an inscription "TOP" upwards. The prevention Not to mix in places sealing rings as the top and second sealing rings have a different profile. 6. To combine in steams pistons with sleeves of cylinders. It is necessary to use a special holder for rings. At installation it is necessary to observe adjusting signs. The arrow on the piston should be directed towards a camshaft drive, and a sign on a cylinder sleeve (in case of installation) – On the same party, as before removal. 7. To establish sleeves of cylinders together with their round sealing rings in the block of cylinders. If sleeves are established repeatedly it is necessary to keep their position concerning the block of cylinders. Pistons should be established so that the arrow has been directed towards a camshaft drive. At installation of pistons in the cylinder preliminary to compress piston rings оправкой (fig. piston Installation in a sleeve of the cylinder by means of a special holder for piston rings see). 8. To establish covers of rods with loose leaves and to tighten their necessary moment. 9. To establish on cranked to a shaft an asterisk of the oil pump together with шпонкой and a chain. 10. From outside a camshaft drive to establish the cover of the radical bearing greased with means Loctite. 11. By means of special send 0.153D to establish a sealing ring (fig. send a sealing ring of a cranked shaft from outside a camshaft see the Sizes). 12. To put on a chain the oil pump, to arrange under the pump a support. To fix the pump. 13. To fix the oil pallet together with its lining. 14. To establish a cranked shaft in installation position timing: шпонка should be turned towards the pump of a cooling liquid and it is established horizontally. 15. To take an adjusting element. Спомощью, for example, выколотки for pins to adhere it so that it acted over a surface of the block of cylinders, and to establish a head of the block of cylinders. 16. To establish a gear belt and to adjust its tension.
