7.21.3. Installation of pistons with rods


Installation of an insert in a rod cover

Ledge under the piston bottom on 6-cylinder petrol DOHC engines
On 6-cylinder petrol DOHC engines the ledge under the bottom of the piston has to settle down from a flywheel.

Installation of the piston in the cylinder with use of wooden whetstone or the handle of the hammer

Tightening of bolts of fastening of a cover of the lower head of a rod, dovorachivy them on a certain corner

PERFORMANCE ORDER
1. Clear a back part of a connecting rod and the place of its installation in rods and covers of rods. Establish inserts in rods and covers of rods (see rice. Installation of an insert in a rod cover).
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 piston the special device for compression of piston rings.
4. Insert the piston with adaptation squeezing rings into the top part of the first cylinder. At the same time the arrow has to be directed to the bottom of the piston towards a driving chain, and tags on rods and covers of rods were in the same situation, as before removal (see rice. A ledge under the piston bottom on 6-cylinder petrol DOHC engines). Using wooden whetstone or the handle of the hammer, press on the piston and press it into the cylinder.
5. 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. Screw up bolts of fastening of a cover of a rod the required moment.
6. Similarly install other pistons with rods.
7. Further installation is made in the sequence, the return to removal taking into account the next moments.
8. On 4-cylinder petrol engines install the oil pallet and a head of the block of cylinders.
9. On 6-cylinder petrol SOHC engines install the oil pump, the oil pallet and a head of the block of cylinders.
10. On 6-cylinder petrol DOHC engines install the oil pump, a masloulavlivayushchy plate, the oil pallet and a head of the block of cylinders.
11. On diesel engines install the oil pump, a masloulavlivayushchy plate, the oil pallet and a head of the block of cylinders.
