Fig. 2.12. Removal of the drive of the camshaft: 1 – forward protective cover; 2 – rubber sealant; 3 – gear belt; 4 – camshaft pulley; 5 – cogged pulley of a bent shaft; 6 – remote washer; 7 – tension roller
|
Remove a forward cover of 1 (fig. 2.12) of a gear belt. Turn off a nut of fastening of the mechanism of a tension. Weaken and take off a gear belt 3. Shoot a tension video 7 with a remote washer 6.
Holding a pulley 4 camshafts from a provorachivaniye with adaptation 67.7811.9509, turn off a bolt of fastening of a pulley, remove a pulley and a spline. Remove the cogged pulley 5 from a bent shaft.
Fig. 2.13. Removal of the pump of cooling liquid: 1 – back protective cover of a gear belt; 2 – pump of cooling liquid; 3 – laying
|
Turn off bolts of fastening of the pump 2 (fig. 2.13) of cooling liquid. Turn off a bolt and a nut of fastening of a back cover of 1 gear belt and remove it. Take out from a nest in the block of cylinders the pump of cooling liquid with laying 3.
Remove a final collector with laying.
Disconnect hoses from the thermostat and remove it. Remove the bringing pipe of the pump of cooling liquid and the taking-away cooling shirt branch pipe with laying.
Adaptation A. 60312 (fig. 2.14) remove an oil filter with laying. Disconnect from branch pipes on a cover of a head of cylinders and on the block of cylinders a hose of the exhaust ventilation of a case. Take out the index of level of oil.
Uncover a head of cylinders. Turn off bolts of fastening of a head of cylinders and remove it assembled with the camshaft. If necessary sort a head of cylinders as it is specified in subsection. "Head of cylinders".
Fig. 2.15. Removal of the oil pump: 1 – oil pump; 2 – laying of the oil pump; 3 – receiver of the oil pump; 4 – laying of a case; 5 – case; 6 – sensor of provision of a bent shaft
