Removal

PERFORMANCE ORDER
1. Establish the piston of 1st cylinder in ВМТ a compression step (subsection 3.1.1.3 see).
2. Uncover heads of cylinders (subsection 3.2.1.4 see).
3. Uncover a chain drive of cam-shafts (subsection 3.2.1.6 see).
4. Remove the oil filter (subsection 2.2.1 see). In case of filter damage at removal replace the filter.
5. Turn away a nut and bolts of fastening and get натяжитель chains. Remove a ring lining натяжителя.
The prevention

At removal натяжителя rotation коленвала is not supposed.


6. Turn away bolts of fastening and remove top directing to a chain from the top part of a head of cylinders.
7. Turn away a bolt of an axis of a boot натяжителя chains and remove a boot from the block of cylinders.
8. Release and turn on bolts (arrows) and remove успокоитель.
9. Release bolts of asterisks of cam-shafts, keeping each of cam-shafts рожковым a key for лыски in a forward part, get each of bolts together with a washer.
10. Remove asterisks from cam-shafts. At easing of adjusting pins in end faces of cam-shafts, remove pins and store together with asterisks.
11. Remove a chain from a leading asterisk коленвала.
12. If necessary remove an asterisk with коленвала, preliminary having paid attention to correct position of an asterisk, and remove шпонку (at easing шпонки in a flute коленвала). Store шпонку together with a leading asterisk.

Condition check

PERFORMANCE ORDER
1. Check up presence on the leader and two conducted asterisks of such signs of deterioration and defects as сколы, крючковатость or absence of teeths. At detection of any of the listed signs of deterioration and damages it is necessary to replace all asterisks, and also a chain in the complete set.
2. Examine chain links, check up deterioration of rollers. Degree of deterioration of a chain can be defined on a deflection in a horizontal plane. In a new chain the deflection almost is absent. If in chain links is available appreciable axial люфт it is necessary to replace a chain. Keep in mind that irrespective of presence of external signs of deterioration, also it is necessary to replace a chain after considerable run or if on the working engine appreciable noise from outside chains is listened. Insistently it is recommended to change a chain in the complete set with asterisks as installation of a new chain on the worn out asterisks, or on the contrary, leads to the strengthened deterioration of a new detail and does not justify from the point of view of expenses. If the condition of chains and asterisks casts doubts address for the qualified consultation in car-care centre Nissan service.
3. Check up presence of signs of deterioration or damages on успокоителе and directing chain in a place of contact to a chain, at detection of defects replace these details.
4. The condition натяжителя can be estimated only by comparison with a new detail. If the condition натяжителя casts at least small doubt it is necessary to replace it.

Installation

PERFORMANCE ORDER
1. Be convinced that the piston of 1st cylinder still is in ВМТ a compression step (a flute under шпонку on a sock коленвала should be turned vertically upwards if to look on the right side of the engine). Insert шпонку into a flute on a sock коленвала.
2. Correctly сориентируйте a leading asterisk коленвала (the adjusting label on an asterisk should be turned aside from коленвала, and the flute in an asterisk should be combined with шпонкой) and dress on коленвал.
3. In a chain there are three links different on colour (are specified by arrows), each of which corresponds to a separate adjusting label. Two links which are is more close to each other, correspond to adjusting labels of cam-shafts, the third link should coincide from an adjusting well-aimed leading asterisk коленвала.

The prevention

On some cars those links of a chain which correspond to adjusting labels of asterisks of cam-shafts, can differ on colour from a link corresponding to an adjusting label of a leading asterisk.


4. Сориентируйте a chain so that different links on colour have been directed outside and settled down opposite to corresponding adjusting labels, get a chain on a leading asterisk, having combined a link (arrow) allocated with colour with an adjusting label on an asterisk.
5. Establish conducted asterisks on cam-shafts of inlet and final valves, thus adjusting labels on asterisks should be turned outside.
The prevention

Both asterisks are identical.


6. Dress a chain (it is specified by an arrow) in asterisks of a cam-shaft of final valves so that different links on colour were combined with adjusting labels.
7. Then dress a chain (it is specified by an arrow) on asterisks of a cam-shaft of inlet valves, having combined different on colour links with adjusting меткама.
8. Insert into end faces of cam-shafts adjusting pins (if acted in film), combine grooves in asterisks with adjusting pins. Be convinced that different links on colour are combined with corresponding adjusting labels of asterisks. Otherwise remove a chain from asterisks and execute necessary adjustments.
9. After combination of adjusting labels with corresponding links of a chain wrap bolts of asterisks of cam-shafts, having dressed on washer bolts.
10. Tighten bolts with the set moment. During an inhaling do not suppose проворачивания a cam-shaft, keeping it for лыски рожковым a key.
11. Establish успокоитель and tighten a bolt успокоителя with the set moment.
12. Establish a boot натяжителя chains and tighten a bolt of an axis of a boot with the set moment.
13. Establish top directing to a chain on a head of cylinders, tighten bolts with the set moment.
14. Release the clamp lever натяжителя (1), press плунжер in the case and fix in such position by a hook, having thrown with it a pin плунжера (2).
15. Establish on a flange натяжителя a new lining, and in a case flute lay a new sealing ring.
16. Establish натяжитель, having convinced that the arrow on a flange is turned aside from a head of cylinders. Dress washers and tighten nuts натяжителя with the set moment. After an inhaling of nuts the assembly hook should leave automatically gearing with a pin, having released плунжер.
17. Establish the new oil filter and fill the engine with oil (subsection 2.2.1 see).
18. Establish a cover of a chain drive (subsection 3.2.1.6 see).
19. Establish a cover of a head of cylinders (subsection 3.2.1.4 see).
