Removal
- Place the car on a two-post lift and lift the front wheels.
- Disconnect the cable from the negative terminal of the battery.
- Remove:
- right front wheel;
- protective shields under the engine;
- protective fender of the front right wheel arch
- Drain the gearbox oil (within 3 minutes).
- Remove the oil pipe mounting bracket on the oil filter base and plug the holes to prevent oil from leaking out.
- Remove the jet thrust completely.
- Remove the exhaust pipe.
On the right side of the car
- Remove:
- the front right floating brake caliper bracket and to protect the brake hose from damage, secure it to the suspension spring (rice. 3.26);
- unscrew the two bolts securing the intermediate support of the drive shaft in the support bearing (rice. 3.27);
- using the T.Av puller. 476 tie rod end (rice. 3.28);
- unscrew the bolts of the lower fastening of the shock-absorbing strut;
- wheel speed sensor.
- Loosen the lower ball joint tip mounting nut as much as possible and use a ball joint impact puller to press the tip out of the steering knuckle (Figure 3.29).
- Remove the drive shaft - steering knuckle - brake disc assembly. Do not damage the corrugated covers of the drive shafts.
On the left side of the car
- Remove the floating brake caliper bracket and attach it to the suspension spring
- Remove the three bolts securing the drive shaft corrugated boot.
- Using a Tav 476 puller, remove the tie rod end.
- Disconnect the wire from the brake pad wear sensor.
- Remove the bolts of the lower suspension strut mounting.
- Disconnect the tie rod ends and lower ball joints from the steering knuckles.
- Remove the drive shaft - steering knuckle - brake disc assembly.
- Install a universal support and lift the engine up until it hangs out (do it together).
- Remove the right engine pendulum mount bracket (4 bolts) together with the pendulum suspension travel limiter.
- Unscrew the lower nut of the left pendulum suspension (1 bolt).
- Remove the upper accessory drive belt cover.
- Lower the power unit 70 mm and move it to the left.
Attention. Watch the air conditioning system hoses in the area between the air conditioning compressor and the receiver dryer, as the tension in these hoses limits the lowering of the power unit.
- Remove the accessory drive belt.
- Remove the accessory drive belt pulley from the crankshaft.
- Remove the timing belt covers.
- Remove the plug covering the hole for the TDC clamp and insert the TDC clamp Mot. 1318 or 7 mm diameter rod.
Setting the valve timing
- Rotate the crankshaft until the mark on the crankshaft pulley (C, fig. 3.31) will not be directed downward, and the mark (D) on the camshaft pulley - on the left at an angle of approximately 45° (The inner mark A of the camshaft pulley should be opposite the mark on the cylinder head cover) and label (I) injection pump pulley - opposite the mark on the injection pump casing.
- Unscrew the nut (IN) and bolt (E) and loosen the timing belt.
- Remove the timing belt.
Installation
- Make sure that the TDC lock Mot. 1318 is in place.
- Reinstall the tension roller.
- Install the timing belt, aligning the marks on the pulleys and the belt.
Note. The following procedure for adjusting belt tension must be strictly followed.
- Rotating the bolt (E. fig. 3.31) tighten the timing belt, while the bracket-mark (N, fig. 33) tension roller must align with the stop (F) and, without applying much force, tighten the adjusting screw lock nut.
- Remove the TDC lock and turn the crankshaft 3 full turns clockwise until the piston of the 1st cylinder is installed in the TDC position. Re-insert the TDC lock.
- Unscrew the lock nut of the adjusting bolt, then gradually move the tension roller to the nominal position when the hatch mark (G) passes through the center of the bracket-mark (N). Tighten the lock nut to 30 Nm.
Note. Do not rotate the crankshaft against the stroke direction.
- Check the injection timing of the injection pump
- Remove the TDC clamp
- Clean the crankshaft pulley bearing surface
- Apply 2 drops of LOCTITE AUTOFORM locking agent to the crankshaft pulley bearing surface.
- Be sure to replace the crankshaft pulley bolt with a new one
- Further installation is carried out in the reverse order of removal
