Volkswagen Touareg / Touareg repair>> Engine>> Mechanical part (petrol engines 4,2L)>> Removal, installation and tension of a gear belt of a drive of GRM
Removal
Remove the shumoizolyatsionny screen.
Remove an arm of fans together with fans of system of cooling.
Bring a radiator frame into service situation.
Mark the direction of a course of a poliklinovy belt and remove it.
Remove the right and left covers of a gear belt.
Mark with a waterproof felt-tip pen the course direction on a gear belt.
Bring the crankshaft into the top dead point. The mark in a cover of a gear belt A should coincide with a notch on a belt pulley of Century.
Check the provision of gear wheels of cam-shafts. Large openings in adjusting plates
(fig. 2.106)
should settle down the friend opposite to the friend on inside.
Unscrew a carving cap at the left from the block of cylinders
(fig. 2.100)
. The opening of VMT of the crankshaft should be visible behind an opening of a carving cap and to be felt to the touch.
Accurately twist fixing bolt 3242 in an opening against the stop and thus fix the crankshaft from a prokruchivaniye.
Remove an average cover of a gear belt.
Turn off a damper of krutilny fluctuations.
At first turn off a bolt 1 from the case of the oil filter, then bolts of 2 covers of a natyazhitel of a gear belt
(fig. 2.107)
.
Uncover.
Scroll the lever of a tension roller of a gear belt 1 internal shestigrannik in the direction
(fig. 2.108)
.
After the lever will be compressed by a natyazhitel 2 so that openings were in the case and the piston the friend opposite to the friend, fix a natyazhitel a lock pin of T40011.
Insert a clip of cam-shafts of T4000 into adjusting plates of cam-shafts and turn off fixing bolts, having turned them approximately on 5 turns
(fig. 2.109)
.
Remove a clip of cam-shafts of T40005.
After that by means of a two-handled stripper of T40001 and a hook of T40001/2 remove gear wheels of cam-shafts from a cone
(fig. 2.110)
.
Turn off a tension roller (see
fig. 2.111
) and remove a gear belt.
Installation and tension
At first lay a gear belt on a crankshaft 1 gear wheel, then on a by-pass roller of a natyazhitel 2 and after on a tension roller 3. Further, as it is represented in drawing, on gear wheels of cam-shafts and a remenny pulley of the pump of system of cooling
(fig. 2.112)
.
Again establish a clip of cam-shafts of T40005 on gear wheels.
Put 5 mm a drill between the tension lever and the piston of a natyazhitel
(fig. 2.113)
.
Tighten still the weakened tension roller a dinamometrichesky key of V.A.G 1410 with the got graggers of VAS 5122 and a key for tension rollers of T40009 counter-clockwise
(fig. 2.114)
with the moment of an inhaling of 4 N · m.
In this situation Tighten a bolt 1 on 22 N · m.
After that take 5 mm a drill.
Scroll the lever of a tension roller of a gear belt 1 internal shestigrannik in the direction
(fig. 2.114)
.
After the lever will compress the piston in a natyazhitel of a gear belt 2, take out a lock pin of T40011.
Turn the lever of a tension roller of a gear belt 1 internal shestigrannik in the direction
(fig. 2.115)
and put between the case and the lever 7мм a drill.
Fasten gear wheels of cam-shafts with the moment of an inhaling of 55 N · m.
Remove a clip of cam-shafts – T40005.
Again take out a drill inserted between the case and the tension lever.
Unscrew fixing bolt 3242 of an opening, twirl a carving cap
(fig. 2.101)
and tighten it on 30 N · m.
Scroll the crankshaft two times in the direction of rotation of the engine and Check the adjusting size A
(fig. 2.116)
. Preset value of 5 mm.
Further installation is carried out in return sequence.
