The piston

Check

The piston

 PERFORMANCE ORDER

    Check up an external surface of the piston on absence of damages, development or non-uniform deterioration. If necessary, replace the piston. Check up a piston finger, inserting it into a piston aperture. The piston finger should enter smoothly into the piston by pressing it a hand (at a room temperature).

Piston rings


 PERFORMANCE ORDER

    Check up each piston ring on absence of damages and non-uniform deterioration. If necessary, replace piston rings. At piston replacement also it is necessary to replace piston rings.
    Insert a new piston ring into a flute of the piston and щупом measure a backlash between a piston ring and a flute wall. If the backlash exceeds maximum permissible value, replace the piston.

Backlash between a piston ring and a flute in the piston:

The second компрессионное a ring: 0,065–0,11 mm
Maslosemnoe ring: 0.03–0.07

    Measure a backlash in the lock of piston rings, manually having inserted a piston ring into the engine cylinder. The piston bottom push a piston ring in the bottom part of the cylinder.
    Щупом measure a backlash in the lock of a piston ring.

Backlash in locks of piston rings:

The first компрессионное a ring: 0,2–0,3 mm
The second компрессионное a ring: 0,30–0,45 mm
Maslosemnoe ring: 0,20–0,45 mm

Maximum permissible backlash: 0,8 mm

Loose leaves шатунных bearings

 PERFORMANCE ORDER

    Check up working surfaces of loose leaves шатунных bearings on absence of strips, scratches, local corrosion, development and other damages. If necessary, replace loose leaves. If working surfaces of loose leaves шатунных bearings are strongly damaged, check up a condition шатунных necks of a cranked shaft. If the cranked shaft also is damaged, replace it or for a reuse перешлифуйте necks till next reduced size.
    Measure internal diameter of loose leaves шатунных bearings and diameter of necks of a cranked shaft. If the oil backlash exceeds admissible limits, replace loose leaves and, at necessity, a cranked shaft.

Oil backlash in шатунных bearings: 0,024 – 0,042 mm
Maximum permissible backlash: 0,10 mm

Installation

Rod, piston finger and the piston

 PERFORMANCE ORDER

    Connect the piston to a rod.
    Combine forward labels and insert a piston finger. The piston finger should enter smoothly into the piston by pressing it a hand (at a room temperature). In the presence of the big backlash replace a piston finger.

Piston rings

 PERFORMANCE ORDER

    Establish on the piston a dilator маслосъемного rings and маслосъемное a ring. Пассатижами for a release of piston rings establish компрессионное a ring №2, then establish компрессионное a ring №1. Be convinced that labels on piston rings are directed to the piston bottom.
    Arrange locks of piston rings, as is shown in drawing.
    Establish the piston with piston rings over the first cylinder, thus the label on the piston should be directed to a forward part of the block of cylinders.
    The special adaptation compress piston rings on the piston. The hammer handle press the piston into the cylinder so that the bottom head of a rod was established on a neck of a cranked shaft.
    Establish шатунный the loose leaf in a rod cover. Establish a cover of a rod and fix nuts. The inhaling moment: 25 Nm to tighten on a corner 90 .

Do not use more than three times bolts of fastening of covers of rods.

    Щупом, inserted between a rod and cranked shaft, measure a lateral backlash of a rod.

Nominal lateral backlash of a rod: 0,10–0,35 mm
Maximum permissible backlash: 0,40 mm
