2.30. Removal and installation of pistons and rods

GENERAL INFORMATION

Prevention

At installation it is necessary to use new bolts of fastening of covers of rods.


Drawing of labels of identification on a cover and the bottom head of a rod

PERFORMANCE ORDER
1. Remove a head of the block of cylinders.
2. Remove the oil pallet, a maslozaborny tube of the oil pump and an oil reflector.
3. Using a hammer and a center punch or paint, note the provision of a cover of the bottom head of a rod and cylinder number (see fig. Drawing of labels of identification on a cover and the bottom head of a rod).
4. Turn a cranked shaft so that pistons of the first and fourth cylinders were established in the bottom dead point. Unscrew bolts of fastening of a cover of the bottom head of a rod of the first cylinder. Remove the bottom cover of a rod together with the loose leaf and hold them together.
5. If there is a deposit in the top part of the cylinder, remove it with a scraper from a soft material. Step existence in the top part of the cylinder testifies to excessive wear of the cylinder and need of boring of the cylinder of the engine.
6. Using the hammer handle, вытолкните the piston up the block of cylinders also take it from the block of cylinders. Remove the top loose leaf of a rod from a cranked shaft and hold it together with a rod.
7. Similarly remove the piston of the fourth cylinder.
8. Turn a cranked shaft on 180 ° for installation of pistons of the second and third cylinder in the bottom dead point and similarly remove pistons.
9. Note a relative positioning of the piston and a rod. Using an edge of a thin screw-driver, remove from the piston a lock ring and a hand squeeze out a piston finger. At repeated installation of a piston finger use only new lock rings.
10. Check a piston finger and the bearing of the top head of a rod on wear existence.
11. Rods usually do not demand replacement if before it there was no engine jamming.

Installation

Piston installation in the cylinder on the engine of 1,6 l
At piston installation to the cylinder of the shooter on the piston it should be sent towards a gear belt on the engine of 1,6 l.

Piston installation in the cylinder on the engine of 2,0 l
At piston installation in the cylinder of the shooter on the piston it should be directed towards a gear belt on the engine of 2,0 l.

Ledges on a rod and a rod cover
Ledges on a rod and a cover of a rod should be directed towards a flywheel on the engine of 1,6 l.

Piston installation in the cylinder with use of the handle of a hammer

Installation of the bottom cover of a rod on the engine of 2,0 l

Tightening of bolts of fastening of a cover of the bottom head of a rod dinamometrichesky key

Tightening of bolts of fastening of a cover of the bottom head of a rod dovorachivy them on a certain corner on the engine of 2,0 l

PERFORMANCE ORDER
1. Arrange pistons with rods according to cylinders in which they will work.
2. Clear a back part of shatunny loose leaves and a place of their installation in rods and covers of rods.
3. Grease pistons and piston rings and place locks of piston rings according to requirements.
4. Installation of pistons is necessary for beginning with the first cylinder. Compress piston rings on the piston the special adaptation for compression of piston rings.
5. Insert the piston with the adaptation compressing rings in the top part of the first cylinder. Thus the arrow on a head of the piston should be directed towards a gear belt. Using wooden whetstone or the hammer handle, press on the piston and press it into the cylinder (see fig. Piston installation in the cylinder on the engine of 1,6 l, piston Installation in the cylinder on the engine of 2,0 l, Ledges on a rod and a rod cover, piston Installation in the cylinder with use of the handle of a hammer).
6. Check combination of the bottom head of a rod with a neck of a cranked shaft. If necessary tighten the piston a rod and establish the bottom head of a rod with the loose leaf on a neck of a cranked shaft. The ledge on the basis of a cover подшипни a rod should be directed towards a flywheel. Screw up bolts of fastening of a cover of a rod the demanded moment (see fig. Installation of the bottom cover of a rod on the engine of 2,0 l, the Tightening of bolts of fastening of a cover of the bottom head of a rod a dinamometrichesky key, the Tightening of bolts of fastening of a cover of the bottom head of a rod dovorachivy them on a certain corner on the engine of 2,0 l).
7. Similarly establish other three pistons with rods.
8. Establish an oil reflector, a pipe of a maslopriyemnik and the oil pallet.
9. Establish a head of the block of cylinders.
