CHANGES IN XUD 7TE, XUD 9 AND XUD 9TE ENGINES

Laying of a head of the block of cylinders

Some engines have the block of cylinders designated by a symbol "V" which is characterized by a ledge of pistons over edge of cylinders, equal or big 0,84 mm. In them it is necessary to establish surely laying of a head 1,83 mm thick which is designated by four cuts.

Springs of valves

Since December, 1988 valves are equipped only with one spring which replaced knot from two springs.

Diameter
29 mm
Height under load of 320 N
42,4 mm
Height under load of 550 N
33,0 mm
Diameter of a wire
3,8 mm
Color of designation
blue, colors of "a sea wave"

Saddles and final valves

For unification XUD 7T and XUD 9 engines are equipped with the same nests of final valves, as well as in the THAT XUD 9 engine.

Application of this modification led to the fact that deepening of a nest of the final valve concerning the surface of connection of a head of the block of cylinders became equal 2,5 mm instead of former 2 mm, and also the plate thickness of the valve for preservation of former extent of compression respectively increased.

Heads of new type are identified by means of openings with a diameter of 9 mm (instead of openings with a diameter of 7 mm) in the ledges located over glow plugs.

Since January, 1992 the XUD 9 engine with the modified head of the block of cylinders has the designation XUD 9A/L.

Components of both types of heads of the block of cylinders are not interchanged.

System of gas distribution

Engines were gradually equipped with gear belts from the materials HSN (Hydrogene Sature Nitrile) which are characterized by the increased stability on influence of oils and the increased temperature.

These belts have the designation HSN.

In case of replacement of a belt it is necessary to establish a HSN belt surely.

Brand and type: Pirelli 136 RPP 254 or Gates HTD 58136x1.

Since January, 1990 in cars with system of steering without hydraulic booster diaphragm vacuum pumps are gradually replaced with bladed rotational pumps with the drive directly from the camshaft. As a result of this modification the camshaft was changed – its length for providing the drive of the pump of low pressure was increased.

Starting with serial number 70 491 894 the vacuum pump on the end of the camshaft is also installed in cars with system of steering with the hydraulic booster.

In cars with conditioning the former decision is left.

Since model of 1993 the thermostat 89 ° is replaced with the thermostat 83 °.

Since model of 1993 former sensors of temperature are replaced on new with the following characteristics:

1st step:
  – without conditioning
92,5 °C
  – with conditioning
90 °C
2nd step:
  – without conditioning
97,5 °C
  – with conditioning
101 °C

Turbocompressor

Starting with numbers of engines 1CV33-49714, 1CV35-67544, 1CV47-77513, 1CV48-20272, 1CV87-2457 fastening of a returnable oil pipeline on a turbocompressor was changed for improvement of tightness of connection. The bringing oil pipeline was also subjected to change.

Separate parts of both types of fastening are not interchanged.
