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 tags of identification on a cover and the lower head of a rod

PERFORMANCE ORDER
1. Remove a head of the block of cylinders.
2. Pick up the oil pallet, the maslozaborny phone of the oil pump and a reflector of oil.
3. Using the hammer and a center punch or paint, note the provision of a cover of the lower head of a rod and number of the cylinder (see rice. Drawing tags of identification on a cover and the lower head of a rod).
4. Turn a bent shaft so that pistons of the first and fourth cylinders were installed in the lower dead point. Unscrew bolts of fastening of a cover of the lower head of a rod of the first cylinder. Remove the lower cover of a rod together with an insert and you hold them together.
5. If there is a deposit in the top part of the cylinder, remove it with a scraper from soft material. Existence of a step 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, push out the piston of the block of cylinders up and take it from the block of cylinders. Remove the top insert of a rod from a bent shaft and you hold it together with a rod.
7. Similarly remove the piston of the fourth cylinder.
8. Turn a bent shaft on 180 ° for installation of pistons of the second and third cylinder in the lower dead point and similarly remove pistons.
9. Note a relative positioning of the piston and a rod. Using an edge of the thin screw-driver, remove a lock ring from the piston 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 for wear existence.
11. Rods usually do not demand replacement if before it there was no jamming of the engine.

Installation

Installation of the piston in the cylinder on the engine of 1,6 l
At installation of the piston to the shooter's cylinder on the piston it has to be sent towards a gear belt on the engine of 1,6 l.

Installation of the piston in the cylinder on the engine of 2,0 l
At installation of the piston in the shooter's cylinder on the piston it has to be directed towards a gear belt on the engine of 2,0 l.

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

Installation of the piston in the cylinder with use of the handle of the hammer

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

Tightening of bolts of fastening of a cover of the lower head of a rod dynamometer key

Tightening of bolts of fastening of a cover of the lower 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 connecting rods and the 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 needs to be begun with the first cylinder. Squeeze piston rings on the piston the special device for compression of piston rings.
5. Insert the piston with adaptation squeezing rings in the top part of the first cylinder. At the same time the arrow on a head of the piston has to be directed towards a gear belt. Using wooden whetstone or the handle of the hammer, press on the piston and press it into the cylinder (see rice. Installation of the piston in the cylinder on the engine of 1,6 l, Installation of the piston in the cylinder on the engine of 2,0 l, Ledges on a rod and a cover of a rod, Installation of the piston in the cylinder with use of the handle of the hammer).
6. Check combination of the lower head of a rod with a neck of a bent shaft. If necessary tighten the piston a rod and establish the lower head of a rod with an insert on a neck of a bent shaft. The ledge on the basis of a podshipna cover of a rod has to be directed towards a flywheel. Screw up bolts of fastening of a cover of a rod the required moment (see rice. Installation of the lower cover of a rod on the engine of 2,0 l, Tightening of bolts of fastening of a cover of the lower head of a rod a dynamometer key, Tightening of bolts of fastening of a cover of the lower head of a rod dovorachivy them on a certain corner on the engine of 2,0 l).
7. Similarly install other three pistons with rods.
8. Establish an oil reflector, a pipe of an oil receiver and the oil pallet.
9. Establish a head of the block of cylinders.
