2.8.4. Removal and installation of a forward sealing flange crankshaftа with an epiploon crankshaftа

Removal

Fig. 2.306. Removal damperа крутильных fluctuations


Remove damper крутильных fluctuations (fig. 2.306).
Turn off a pulley of a belt drive from the water pump.
For untwisting of bolts as a countersupport use цапфовый a key.
Unscrew bolts.

Fig. 2.307. Fastening of a forward sealing flange


Remove a forward sealing flange (fig. 2.307).

Installation
Remove old hermetic from a flute of a sealing flange, and also from landing surfaces.
Remove the rests of hermetic from a sealing flange and the block of cylinders, and also from the oil pallet, for example, a rotating brush-nozzle with a plastic bristle.
Clear landing surfaces; on them there should not be an oil and greasings.
Cut off a tube nouse on a forward mark (diameter an aperture about 2 mm).

Fig. 2.308. Filling of a flute of a landing surface with hermetic


Put silicone hermetic on a pure landing surface of a sealing flange how it is shown in drawing 2.308.
The flute of a landing surface should be filled by hermetic.
The hermetic platen should act over a landing surface on 1,5–2,0 mm.

THE NOTE
The hermetic platen should be not thicker than the specified sizes, otherwise superfluous hermetic can get to the oil pallet and litter the mesh filter of the oil pump.

The sealing flange should be established during 5 mines after hermetic drawing.

Fig. 2.309. The scheme of installation of the adjusting tool


Establish the adjusting tool on распорную the plug and spread a sealing flange 1 on распорную the plug (fig. 2.309).
Take the adjusting tool.

Fig. 2.310. Flange installation on crankshaft


Establish a sealing flange 1 with inserted распорной the plug on crankshaft (fig. 2.310).
Twirl bolts пошагово cross-wise (fig. 2.307).
The further installation is carried out in return sequence.
Establish damper крутильных fluctuations.
Establish полиwedge a belt.
Establish a framework of a radiator with hinged details.
Establish facing of a forward bumper.

The inhaling moments
Forward sealing flange to the block цилиндров* – 9 Нм.
Pulley of a belt drive to the water pump – 20 Нм.
* Tighten пошагово cross-wise.
