Removal

PERFORMANCE ORDER
1. Disconnect a hose of ventilation of a case.
2. Remove a pulley of the water pump and a bent shaft.
3. Remove a casing of a gear belt.
4. Take away a roller of a tension of a gear belt to the water pump and temporarily enshrine it in this provision.
5. Take off a gear belt from a camshaft pulley.
6. Remove a camshaft pulley.

Check

PERFORMANCE ORDER
1. Check the camshaft for lack of uneven wear, cracks or damages.
2. Measure height of each cam of the camshaft in two points.

Nominal height of cams of the camshaft of inlet valves: 42,8575 mm
Nominal height of the camshaft of final valves: 42,7354 mm
Minimum admissible height of cams of the camshaft of inlet valves: 42,3575 mm
Minimum admissible height of the camshaft of final valves: 42,2353 mm

3. Check surfaces of cams for lack of uneven wear and damages.
4. Check each bearing for absence of damage. If the working surface of the bearing is excessively damaged, replace a head of cylinders or a cover of the bearing of the camshaft.

Forward sealing ring of the camshaft

PERFORMANCE ORDER
1. Check working edges of a sealing ring for lack of wear. If the working edge is worn-out or damaged, replace a sealing ring.
2. Check the surface of the camshaft contacting to a sealing ring. If this surface is evenly worn-out, replace the camshaft.

Axial side play of the camshaft: 0,07–0,28 mm.

Installation


PERFORMANCE ORDER
1. Before installation apply a thin film of pure engine oil on all surfaces of sliding of the camshaft. Install the camshaft.
2. Establish covers of bearings of the camshaft.
3. Install the ignition coil.
4. Establish a shaft of yokes and a yoke.
5. Oil engine working edges and an external surface of a sealing ring and establish by the special tool 09221-21000 a sealing ring on a forward part of the camshaft.
Establish by blows of the hammer to special adaptation a sealing ring against the stop in a nest.
6. Establish a pulley of the camshaft and fix it by a bolt.

Inhaling moment: 80–100 N • m

7. Combine an adjusting tag of the camshaft and an adjusting tag of a pulley of a bent shaft with indexes, at the same time the piston of the 1st cylinder will be in VMT in a compression step.
8. Establish laying in deepening of a cover of a head of cylinders.
9. Temporarily establish a cover of a head of cylinders.
10. Launch the engine and leave it to work at the frequency of rotation of a bent shaft idling.
11. Tighten bolts of fastening of a cover the required moment.

Inhaling moment: 8–10 N • m

12. Establish casings of a gear belt.
13. Establish a pulley of the water pump and a pulley of a bent shaft.
