- Remove a head of the cylinder with an inlet collector, a collector of an exhaust system and a water taking away pipe, having addressed to Section Valves and a head of the block of the cylinder in this Chapter.
- Remove the oil pump, having addressed to Section the Oil pump in this Chapter.
- Note cylinder number on all pistons, rods and covers of bearings of a rod.
- Remove covers of bearings of a rod.
|
|
- Establish directing hose (1) over a carving шатунных bolts. It prevents damage of a neck of the bearing and a carving шатунных bolts at rod removal.
|
- Remove a deposit from top of an aperture of the cylinder before to get the piston from the cylinder.
- Push out the piston and rod knot at the top from a cylinder aperture.
|
|
Dismantling
|
|
|
|
- By means of a dilator of piston rings remove two компрессионных rings (top and the second) and маслосъемное a ring from the piston.
|
- Remove a piston finger from a rod.
- Loosen the lock rings of a piston finger (1).
|
|
Cleaning
Remove a deposit from the bottom of the piston and flutes of a piston ring by means of the suitable tool.
Check
The cylinder
|
|
- Check up walls of cylinders about scratches, roughnesses or the ledges specifying in excessive deterioration. If a cylinder trunk very rough or strongly scratched, or with ledges, chisel the cylinder and use the piston большего the size.
- With the help компрессиметра measure internal diameter of the cylinder in a direction of draught and an axial direction in two positions. If you notice something from following positions, chisel the cylinder.
- Internal diameter of the cylinder falls outside the limits norms.
- The difference of measurements in two positions falls outside the limits a bias.
- The difference between measurements of axial section and a draught direction leaves with a deviation from круглости.
|
|
1 — 50 mm (1.96 inches)
2 — 95 mm (3.74 inches) |
|
|
- Limit of internal diameter of the cylinder: 84.050 mm (3.3090 inches)

- Limit: 0.10 mm (0.0039 inches)
- Internal diameter of the cylinder with a deviation from круглости:
- Limit: 0.10 mm (0.0039 inches)
|
|
|
If though one of four cylinders has to be chiseled, chisel all four cylinders on the same больший the size. It is necessary for the purpose of uniformity and balance preservation. |
|
|
Pistons
|
|
- Investigate pistons about defects, cracks and other damages. The damaged or faulty pistons should be replaced.
Diameter of pistons
- Diameter of the piston should be measured in a point of 26.5 mm (1.04 inches) from the end of a skirt of the piston in a direction perpendicular to a piston finger.
|
|

Piston backlash
|
|
- Measure internal diameter of the cylinder and diameter of the piston to find a difference which will be a piston backlash. The piston backlash should correspond to the technical requirements specified below. If it does not correspond to technical requirements, chisel the cylinder and use the piston большего the size. A piston backlash: 0.02 – 0.04 mm (0.0008 – 0.0015 inches).

|
|
1 — 26.5 mm (1.04 inches) |
Backlash of grooves of rings
|
|
- Before to check, it is necessary to clear, dry and release from a deposit of a groove of the piston. Put a new piston ring (1) in a piston groove, and measure a backlash between a ring and a crosspiece between two flutes of piston rings with the help калибромера (2).
|
- If the backlash does not correspond to technical requirements, replace the piston.
- Backlash of a groove of rings

- The second: 0.02 – 0.06 mm (0.0008 – 0.0023 inches)
|
|
Piston finger
|
|
|
|
- Check up a piston finger, internal diameter of the plug of a piston head and internal diameter of the piston about deterioration or damage, paying special attention on a condition of the plug of a piston head of a rod. If the piston finger, internal diameter of the plug of a piston head of a rod or internal diameter of the piston are worn strongly out or damaged, replace a piston finger, a rod or the piston.
|

The general information on rod bearings
Repair bearings of a rod happen the standard size and on 0.25 mm (0.0098 inches) less, bearings of the smaller size happen 5 types different from each other by stability to influence. That it was possible to distinguish the bearing of the smaller size, it is painted in red colour in a point shown in drawing, the thickness of the bearing of the smaller size in the centre makes 1.605 – 1.615 mm (0.0632 – 0.0635 inches).
Visual survey of the bearing of a rod
Examine bearing loose leaves on a subject оплавления, изъязвлений, прожога or отслаивания and examine drawing of an arrangement of contact. Bearing loose leaves in failure condition should be replaced.
Backlash of the bearing of a rod
|
|
- Before to check a bearing backlash, clean the bearing and a rod neck.
- Establish the bearing in a rod and a bearing cover.
|
|
- Put a part of a plaster solution (1) for full width of a neck of a rod in a place of contact of the bearing (in parallel коленвалу), bypassing lubricant apertures.
|
- Establish a cover of the bearing of a rod on a rod.
|
|
- At cover installation be convinced that the arrow (1) on a cover specifies in the pulley party коленвала. Having greased with engine oil rod bolts, twirl cover nuts by the specified rotating moment. The rotating moment of an inhaling: a nut of a cover of the bearing of a rod (): 45 Н•м (4.5 kg th, 33.0 pound on foot).
|
|
|
DO NOT TURN коленвал with a plaster solution inside. |
|
|
- Uncover and by means of a ruler (2) on a cover of a plaster solution (1), measure width of a plaster solution (1) in the widest place (backlash). If the backlash falls outside the limits norms, use the new bearing of the standard size, having addressed to subsection the Selection of bearings of a rod in this Section. After selection of the new bearing try on a backlash.
- Backlash of the bearing of a rod:
- Norm: 0.045 – 0.063 mm (0.0018 – 0.0024 inches)
- Limit: 0.08 mm (0.0031 inches)
|
- If it is impossible to result a backlash in norm limits even with the new bearing of the standard size, replace коленвал or переточите шатунную a neck on the size less nominal as follows.
- Establish the 0.25-millimetric bearing of the smaller size on the big head of a rod.

Selection of bearings of a rod
|
|
- If the bearing is faulty or the bearing backlash does not correspond to technical characteristics, choose the new bearing of the standard size according to the following procedure and establish it.
- If for any reason replace коленвал or a rod and its bearing, choose the new bearing of the standard size for installation, having addressed to the figures printed on a rod and its cover and-or letters, printed on a cheek коленвала the cylinder №3.
|
|
|

|
Assemblage
|
|
To provide a necessary backlash between the piston and the cylinder, there are two sizes of pistons available, in quality spare parts of the standard size. Establishing the piston of the standard size, do not forget to adjust the piston with the cylinder as follows. |
|
|
|
|
- On each piston (1) number (7 1 or 2 is printed. He specifies in external diameter of the piston.
|
- On the block of the cylinder (2) numbers (6 1 or 2 also are printed, and it also is painted in red or blue colour (3). Number specifies in internal diameter of the cylinder.
