Volkswagen Touareg / Touareg repair>> Engine>> Removal and stretcher installation>> Removal and installation of heads of the block of cylinders
Removal
Dismantle the engine and a transmission.
Remove a sound-proof cover and a cover of a head of the block of cylinders from block heads.
Dismantle the fuel pump and the pump of tandemny type from heads of the block of the cylinder.
Establish a cranked shaft in the provision of a dead point of the first cylinder check gazoraspredeleniye phases.
Dismantle leading gear wheels of camshafts.
Unscrew fixing bolts between a cover of the distributive mechanism and a head of the block of the first and second row of cylinders.
Bolts of a head of the block of cylinders weaken and unscrew in the set sequence (
(fig. 2.202)
shows in the movement direction).
By means of the assistant carefully remove heads of the block of cylinders.
Installation
Before installation of heads of the block of cylinders establish a cranked shaft in the provision of a dead point of the first cylinder.
Rotate a cranked shaft against the direction of rotation of a shaft of the engine until all pistons will evenly not stand in situation below a dead point.
Establish sealing laying of a head of the block of cylinders.
Establish a head of the block of cylinders, considering a position of a compensatory slip
(fig. 2.203)
, bolts of a head of the block of cylinders with washers establish and twirl by hand.
Heads of the block of cylinders tighten in four stages in the specified sequence of an inhaling (
(fig. 2.204)
shows the movement direction).
1–Tighten a dinamometrichesky key:
– stage 1 = 30 N · m;
– stage 2 = 60 N · m.
2–Further rotate a usual key:
– a stage 3 = to tighten on 1/2 turns (180 °);
– a stage 4 = to tighten on 1/2 turns (180 °).
Establish leading gear wheels of camshafts.
Adjust gazoraspredeleniye phases.
