3.5.21. Installation of pistons with rods

PERFORMANCE ORDER
1. Clear a back part of a connecting rod and the place of its installation in rods and covers of rods.
2. Grease pistons and piston rings and place locks of piston rings according to requirements.
3. Installation of pistons needs to be begun with the first cylinder. Squeeze piston rings on the porshnespetsialny device for compression of piston rings.
Petrol engines
4. Insert the piston with adaptation squeezing rings into 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.
5. Using wooden whetstone or the handle of the hammer, press on the piston and press it into the cylinder.
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 cover of the bearing of a rod has to be directed towards a flywheel.
7. Screw up bolts of fastening of a cover of a rod the required moment (at the left – tightening of bolts of fastening of covers of bearings of the lower head of a rod the required moment, on the right – tightening of bolts of fastening of the lower cover of a rod, dovorachivy on a certain corner).
8. On engines of 1,8 l and 2,0 establish the main cover of bearings and in the diagonal sequence from the center to edge tighten fastening bolts.
9. On all engines establish an oil receiver pipe, the oil pallet and a head of the block of cylinders.
Diesel engines of 1,7 l
10. Take bolts from the rod basis and establish new bolts in a rod.
11. Insert the piston with the mandrel squeezing piston rings into the top part of the first cylinder. At the same time the adjusting tag on a head of the piston has to be directed to a gear belt.
12. Using wooden whetstone or the handle of the hammer, press on the piston and press it into the cylinder.
13. Check combination of the lower head of a rod with a neck of a bent shaft and, 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.
14. Establish a cover of the lower head of a rod and put the clamps the required moment / dovorachivaniye on a certain corner.
15. Similarly install other three pistons with rods.
16. Turn a bent shaft and check that it rotates freely and without jammings. Establish a partition in the lower part of the block of cylinders and fix by bolts, having tightened them the required moment.
17. Establish an oil receiver pipe, the oil pallet and a head of the block of cylinders.
Diesel engine of 2,0 l
18. Insert the piston with the mandrel squeezing rings in the top part of the first cylinder. Thus the arrow on a head of the piston has to be directed to a gas distribution mechanism drive chain. Using wooden whetstone or the handle of the hammer, press on the piston and press it into the cylinder.
19. Check combination of the lower head of a rod with a neck of a bent shaft and, 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. Establish a cover of the lower head of a rod with an insert. At the same time the ledge on a cover of a rod has to be directed to a flywheel.
20. In several stages tighten fastening bolts the required moment (at the left – tightening of bolts of fastening of a cover of the lower head of a rod a dynamometer key, on the right – tightening of bolts of fastening of a cover of the lower head of a rod with their dovorachivaniye on a certain corner).
21. Similarly install other three piston and a rod.
22. Turn a bent shaft and check that it rotates easily and without jammings.
23. Establish an oil receiver pipe, the oil pallet and a head of the block of cylinders.
