GENERAL INFORMATION

Prevention

Before removal of pistons and rods remove a head of cylinders, the oil pallet and the oil pump.


Dismantle

PERFORMANCE ORDER
1. On engines of 2,7 l remove the balancer shaft (see subsection 3.3.14).
2. By means of development remove the fillet formed as a result of development in the top part of the cylinder.
3. Turn the engine.
4. Check an axial side play of rods, inserting probes between the crankshaft and a rod. The axial side play will be equal to the total thickness of probes at which the side play disappears.
5. If the axial side play of a rod exceeds standard value, then the rod(s) should be replaced. If new rods are established (or the crankshaft), then the axial side play can be less norm (in this case it is necessary to proshlifovat rods, if necessary consult in a workshop of car service). Repeat the procedure for other rods.
6. In the absence of tags on rods and covers of rods (marking is specified by an arrow) to a nakernita on them number of the corresponding cylinder.
7. Weaken an inhaling of nuts of covers, turning off them on 1/2 turns at one time until nuts do not begin to turn away by hand. Uncover a rod of the first cylinder together with an insert, do not take an insert from a cover.
8. Push out the piston with a rod and an insert through the top part of the cylinder, previously having dressed pieces of hoses on bolts. If resistance to movement of the piston is felt, then check purity of removal of a fillet.
8. Turning the crankshaft, repeat the procedure for all other cylinders.
9. Collect rods with covers, tighten nuts of covers by hand.
