Removing and installing toothed belt / installing valve timing Engine RF-N
Adjusting the timing should be carried out after the repair work, which was filmed at the toothed belt or disassemble the engine. When checking the setting the timing should perform all operations, except for replacing the timing belt.
Withdrawal Disconnect the negative battery terminal.
A WARNING When you disconnect the wire from the negative terminal of the battery is erased the memory of electronic storage devices, such as a radio receiver code. |
Lift the car and remove the right front wheel. Remove the bottom engine cover on the right wheel arch.

Set the first cylinder to TDC in the compression stroke. To do this, turn the

engine crankshaft to align the marks on the crankshaft pulley with the mark on the front cover of the cylinder (Fig. 4.13). Secure crankshaft from turning and remove the bolts of the crankshaft pulley. To lock the engine include 5th transfer and the assistant should press on the brake pedal. Remove the crankshaft pulley. Remove the screws and remove the right and left casings of a gear belt. Remove the engine support. Remove the spark plugs. For cranking the engine and apply the parking brake, set the gear lever to the neutral position. With ratchet and head cranked shaft from the right-hand wheel arch.
A WARNING In no case did not turn a cranked shaft of the camshaft pulley through a belt drive. |
Chalk, markers or paint, mark the direction of rotation of the toothed belt. If you are installing the toothed belt will rotate in the opposite direction, it will collapse. Motor pulley rotates clockwise.
| Fig. 4.14. Loose bolts and removal of the tension roller of a gear belt
|
Loosen the bolt of a tension roller and move the tension roller of a gear belt (Fig. 4.14). After loosening the toothed belt tension, retighten the bolt tensioning pulley. Remove pulley. Remove the timing belt. After removal of the timing belt pulleys do not turn.
WARNINGS Before removing the toothed belt again to check that the mark on the camshaft pulley to the edge of the cylinder head, and if necessary, adjust the position of the pulleys. If it is necessary to crank the camshaft when removing the toothed belt, none of the piston must be in the TDC, as might otherwise be severely damaged pistons and valves. |
If you want to rotate the camshaft, pistons are pre-set in the middle of all of their travel. To do this, put a chalk mark on top of the crankshaft pulley with the crankshaft must be in the TDC position of first cylinder, then turn the crankshaft pulley 1/4 turn (90 ?�) to the left or right. Now, the label must be directed to the left or right.
A WARNING Do not bend or fold the toothed belt. Always replace contaminated, damaged or worn belts. Check the uniformity and ease of rotation of the tensioning pulley. |
Setting Make sure that the mark on the crankshaft pulley coincides with the mark on the front cover of the cylinder, and the label on a pulley of a camshaft - a mark on the back casing of a gear belt. If necessary, turn the pulleys to align all the labels. Install the timing belt pulleys. Old Route the belt in accordance with the previously applied by the arrow indicating the direction of rotation of the belt. Install the pulley and fix a bolt, having tightened its moment of 50 N ??? m.
A WARNING Make sure that the belt pulleys are well covered and do not sag. |
Adjust the belt tension Loosen the bolt tension roller so that the roller can move to a gear belt under spring force. Rotate the crankshaft two turns clockwise to align the label of a camshaft with a label on the back casing of a gear belt. Once again, make sure that all the labels are the same. Tighten the bolt of a tension roller 50 N ??? m. Rotate the crankshaft two turns in the direction of rotation of the engine and recheck the alignment marks.

A branch of a gear belt between pulleys high pressure fuel pump and camshaft must bend to 9,0-11,0 mm when pressing the belt force of 10 kgf (strong fingers) (Fig. 4.15). Otherwise, loosen the bolt of a tension roller, and again adjust the belt tension. Establish and fix bolts right and left casings of a gear belt, tightening the bolts to 10 N ??? m.
| Fig. 4.16. Location nuts and bolts of the upper engine mount RF-N
|
Install the upper engine mounting and tighten the bolt to 115 N ??? m, and the nut to 90 N ??? m (Fig. 4.16). Lock the crankshaft from turning, tighten the bolts of the crankshaft pulley and tighten to 30 N ??? m. To lock the engine include 5th transfer and the assistant should press on the brake pedal. Replace the spark plugs. Install and tighten the V-belt. Replace the cover on the right wheel arch. Attach the wire to the negative terminal of the battery. If there are clock, set the time and enter the security code radio.
