Establish directing hose (1) over a carving шатунных bolts. It is necessary to avoid damage of a pin of the bearing and a carving шатунных bolts at rod removal.

Ослабьте lock rings of a piston finger (1).

Remove a piston finger.

The difference between measurements of axial section and a draught direction leaves with a deviation from “круглости”.
Limit of internal diameter of the cylinder: 75.15 mm (2.9586 inches) Bias of internal diameter of the cylinder
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.

Diameter of the piston should be measured on distance of 23 mm (0.91 inches) (1) from the end of a skirt of the piston in a direction perpendicular to a piston finger.

Norm

74.970 – 74.990 mm (2.9516 – 2.9523 inches)

The repair size: 0.50 mm (0.0196 inches)

75.470 – 75.480 mm (2.9713 – 2.9716 inches)

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).

The internal diameters of the cylinder used here, are measured in a draught direction in two positions.

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).

Check up a backlash of a piston finger on the top head of a rod. Replace a rod if its top head is worn strongly out or damaged or if the measured backlash leaves for an admissible limit.

Norm: 0.003 – 0.016 mm (0.0001 – 0.0006 inches) Limit: 0.05 mm (0.0020 inches)

Internal diameter of a small head of a rod: 19.003 – 19.011 mm (0.7482 – 0.7484 inches)

 Diameter of a piston finger: 18.995 – 19.000 mm (0.7478 – 0.7480 inches)

Check up a lateral backlash of the big head of a rod, having inserted and having attached a rod to it шатунной to a neck regularly. If it will appear that the measured backlash falls outside the limits norm, replace a rod.
Lateral backlash of the big bottom head of a rod
Norm: 0.10 – 0.20 mm (0.—39 – 0.0079 inches) Limit: 0.35 mm (0.0137 inches)

Check up шатунную a neck on presence of non-uniform deterioration or damage. Measure шатунную a neck on a deviation or a bias with the help a micromeasure. If шатунная the neck is damaged or if a deviation or a bias more than an admissible limit, replace коленвал or переточите шатунную a neck, having addressed to point f).

Norm

43.982 – 44.000 mm (1.7316 – 1.7322 inches)

0.25 mm (0.00984 inches) below the nominal

43.732 – 43.750 mm (1.7218 – 1.7224 inches)

Check up bearing loose leaves on presence оплавления, изъязвлений, прожига or peelings and examine a configuration of contacts. The damaged loose leaves of the bearing should be replaced. There are two types of bearings of a rod available: the bearing of the standard size and the bearing less than standard size of 0.25 mm. That they could be distinguished, on the bearing of the smaller size of 0.25 mm are number (US 025), printed on its back party, and the bearing of the standard size without number.

a. Before to check a bearing backlash, clean the bearing and a rod neck.
b. Establish the bearing in a rod and a bearing cover.
c. 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.

d. Establish a cover of the bearing of a rod (1) on a rod. At cover installation be convinced that the arrow (2) on a cover specifies in the pulley party коленвала (3). Having greased with engine oil rod bolts, twirl nuts of a cover with specified rotating the moment. Do not turn коленвал with a plaster solution inside. The rotating moment of an inhaling: a nut of a cover of the bearing of a rod () — 35 Н•м (3.5 kg th, 25.5 pound on foot).

e. Uncover and by means of a ruler (2) on a cover of a plaster solution (1), measure width of a plaster solution in the widest place (backlash). If the backlash falls outside the limits norms, use the new bearing of the standard size and try on a backlash.

Oil backlash of the bearing of a rod

The lock ring should be established a detachable part upwards or downwards.

Establish piston rings in the piston:
The first ring (1) differs from the second ring (2) under the form and marks. Distinguish the first ring from the second, having looked at drawing, and establish these piston rings in the piston, directing the marked party of each ring on the top of the piston. Establishing маслосъемное a ring (3), at first put распорку, and then two erasing edges маслосъемного rings.

Do not put oil between a rod and the bearing or between a cover of the bearing and the bearing.

Establish directing sleeves over rod bolts. These directing sleeves protect шатунную a head and a carving of bolts of a rod from damage at installation of a rod and piston knot.

Establish the piston and rod knot in a cylinder trunk. Use the special tool (the compressor of piston rings) to compress rings. Direct a rod into place in коленвале. By means of the hammer handle besiege easy blows a piston head to establish the piston in a trunk. Firmly hold the compressor of rings against the block of cylinders until all piston rings will not enter into a cylinder trunk. The special tool: () 09916-77310.

Establish a cover of the bearing (1): establish an arrow (2) on a cover towards a pulley коленвала (3). Fasten cover nuts according to technical recommendations. The rotating moment of an inhaling: a nut of a cover of the bearing of a rod () — 35 Н•м (3.5 kg th, 25.5 pounds on foot).
