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

Lining of a head of the block of cylinders

Some engines have the block of cylinders designated by a symbol "In" which is characterised by a ledge of pistons over the edge of cylinders equal or big 0,84 mm. In them it is necessary to establish necessarily a lining of a head in the thickness of 1,83 mm which is designated by four cuts.

Springs of valves

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

Diameter

Height under loading 320 Н
42,4 mm
Height under loading 550 Н
33,0 mm
Diameter of a wire
3,8 mm
Colour of a designation
Blue, colours of "a sea wave"

Saddles and final valves

With a view of unification engines XUD 7Т and XUD 9 are equipped by the same nests of final valves, as well as in engine XUD 9ТЕ.

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

Heads of new type are identified by means of apertures in diameter of 9 mm (instead of apertures in diameter of 7 mm) in the ledges located over candles накаливания.

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

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

System timing

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

These belts have designation HSN.

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

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

Since January, 1990 in cars with system of a steering without the hydraulic booster диафрагменные vacuum pumps are gradually replaced on лопастные rotational pumps with a drive directly from a camshaft. As a result of this updating the camshaft has been changed – its length for maintenance of a drive of the pump of low pressure has been increased.

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

In cars with air-conditioning the former decision is left.

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

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

1st step:
  – Without air-conditioning
92,5 WITH
  – With air-conditioning
90 WITH
2nd step:
  – Without air-conditioning
97,5 WITH
  – With air-conditioning
101 WITH

Турбокомпрессор

Since numbers of engines 1CV33-49714, 1CV35-67544, 1CV47-77513, 1CV48-20272, 1CV87-2457 fastening returnable маслопровода on турбокомпрессоре has been changed for improvement of tightness of connection. To change also has been subjected bringing маслопровод.

Separate parts of both types of fastening are not interchangeable.
