Folksvagen Sharan/Sharan repair>> The diesel engine>> Head of the block of cylinders>> Installation of a head of the block of cylinders On sale there are linings of a head of the block of cylinders which have a various thickness. The thickness of a lining of a head of the block of cylinders depends on that, pistons over a surface of the block of cylinders how much act. If you change only a head of the block of cylinders or again establish an old head of the block of cylinders with a new lining the new lining can be bought, having looked, how many is available notches or apertures from outside linings. Besides, it is possible to look number of a spare detail of an old lining.
If replacement of pistons, details krivoshipno-shatunnogo the mechanism or the block of cylinders it is necessary to measure anew distance on which pistons over a head of the block of cylinders act is made.
To define a thickness of a lining of a head of the block of cylinders it is necessary to put one of pistons in position ВМТ and by means of a ruler and the indicator to define how much the piston bottom acts over a surface of the block of cylinders (fig. 409 see). Having measured this distance and using the data cited more low, define a thickness of a lining of a head of the block of cylinders.
The lining of a head of the block of cylinders is marked by figures 1, 2 or 3 or is designated by apertures (fig. 408). The arrow shows number of a spare detail on a lining of a head of the block of cylinders. If the lining of a head of the block of cylinders is established correctly this number can be read, looking at a lining of a head of the block of cylinders from above.
Ledge Quantity
Pistons of notches
0,91—1,00 mm 1
1,01—1,10 mm 2
1,11—1,20 mm 3
As it has already been told, the lining of a head of the block of cylinders can be marked by means of the punched apertures. In this case it is necessary to read not «quantity of notches», and «quantity of apertures».
For gauging carrying out establish an indicator pin on the piston, put value of the measuring device on a zero, and then shift a pin on carefully cleared surface of the unit. The received size is equal to distance on which the piston acts from a head of the block of cylinders. Depth badly gives in to measurement as it is very insignificant. Lining number should be defined under the catalogue of spare parts.
There are the special directing bolts, serving to align a head of the block of cylinders at installation on the block of cylinders. If you we will get them establish in 410 place specified in fig., i.e. on "the cold" party of the engine. Otherwise it is necessary to make adjusting screws which should be screwed in the specified places correctly to combine a lining and a head of the block of cylinders. Also in drawing the directing plug which should be located in the unit is shown.
Carefully clear surfaces of a head of the block of cylinders and units.
The lining should be taken out from packing directly ahead of the installation and to address with it it is necessary very cautiously. Put a lining on a head of the block of cylinders and put on a head of the block of cylinders the block of cylinders.
Put on a head of the block of cylinders both directing screws (fig. 410 see), establish directing plug and обстучите its plastic or rubber hammer.
Insert bolts of fastening of a head of the block of cylinders and tighten them by hand.
Turn out both directing screws from the block of cylinders.
Being guided by fig. 411, gradually tighten bolts of fastening of a head of the block of cylinders in the specified sequence and according to the further recommendations:
- In the specified sequence insert a key into each bolt, having remembered position воротка, and tighten each bolt for one approach precisely on a turn quarter, without using thus динамометрический a key. After you will make it on all bolts, tighten them on a turn quarter.
All further works on installation are carried out in return sequence concerning process of removal (item 17.3.1).
