2.4.3.3. Installation of a belt of the GRM drive
Install the piston of the 1st cylinder in compression step VMT.
Fig. 2.235. Combination of adjusting tags on the cogged pulley of a bent shaft and the case of the oil pump
|
Temporarily establish a bolt of a pulley of a bent shaft and, turning a bent shaft, combine adjusting tags on the cogged pulley of a bent shaft and the case of the oil pump (see fig. 2.235).
Fig. 2.236. Check of coincidence of tags on cogged pulleys of camshafts with tags on a GRM drive belt cover No. 3
|
Using the special tool, turn camshafts, having combined adjusting tags on cogged pulleys of shaft and a cover No. 3 of a belt of the GRM drive (see fig. 2.236).
Establish a GRM drive belt.
Fig. 2.239. The sequence of installation of a belt of the GRM drive on mechanism elements
|
Remove if is available, any liquid from cogged pulleys and rollers. At installation of the reused belt be convinced that the arrow is directed towards rotation of a belt. Combine adjusting tags on a belt and a pulley of a bent shaft. Combine adjusting tags on a belt and pulleys of camshafts. Establish a GRM drive belt, putting on it elements in the specified sequence, as shown in the figure 2.239:
1 – cogged pulley of a bent shaft;
2 – pulley of the pump of cooling liquid;
3 – pulley of the forward camshaft;
4 – intermediate pulley;
5 – pulley of the back camshaft;
6 – roller-natyazhitel.
Establish a natyazhitel of a belt of the GRM drive.
Fig. 2.240. The six-sided key fixing a rod
|
Move a rod of a natyazhitel so that to combine openings on a rod and the case of a natyazhitel (effort of 980-9800 N). Record a rod a six-sided key on 1,27 mm. Establish a boot on a natyazhitel. Alternately tighten two bolts of fastening of a natyazhitel the moment of an inhaling of 27 N · m. Take out the six-sided key fixing a rod (fig. 2.240).
Check gas distribution phases. Turn a bent shaft on one turn before combination of adjusting tags on the cogged pulley of a bent shaft and the case of the oil pump (see fig. 2.235). Check whether adjusting tags on pulleys of camshafts and a cover No. 3 of a belt of the GRM drive were combined. If it did not occur, reinstall a belt (see fig. 2.236). Turn off a bolt of a pulley of a bent shaft.
Establish the right support of the engine, having fixed it by the moment of an inhaling of 28 Nanometers.
Establish a GRM drive belt cover No. 2. Check, did not crack whether laying of a cover of a belt was stratified. If necessary replace laying.
Establish a cover No. 2 of a belt of the GRM drive and wrap five bolts the moment of an inhaling of 8 N · m. Establish protection of conducting on a GRM drive belt cover No. 3.
Fig. 2.241. Installation of a guide of a belt of the GRM drive
|
Establish a GRM drive belt guide by the coming-out part (fig. 2.241).
Establish a cover No. 1 of a belt of the GRM drive and wrap four bolts the moment of an inhaling of 8 N · m.
Fig. 2.233. Removal of a pulley of the GRM drive: 1 – special tools
|
Establish a pulley of a bent shaft, having combined a spline on cranked to a shaft with a shponochny groove on a pulley, establish a pulley and, using the special tool, tighten a bolt of fastening of a pulley the moment of an inhaling of 216 N · m (see fig. 2.233).
Establish an arm No. 2 of the generator and acquire a hinged bolt and a nut, without tightening them.
