PERFORMANCE ORDER

Prevention

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


1. Remove the fillet formed as a result of development and deposits of a deposit in the top part of the cylinder, previously having checked a nail existence of a ledge. If not to remove a fillet, then breakage of the piston during its removal is possible.
2. Turn the engine.
3. 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. If the axial side play of a rod exceeds standard value, then the rod 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.
4. In the absence of tags on rods and covers of rods to a nakernita on them number of the corresponding cylinder.
5. Weaken an inhaling of nuts of conrod 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. 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.
6. Turning the crankshaft, repeat the procedure for all other cylinders.
7. Collect rods with covers and bearings, tighten nuts of covers by hand.
