Timing Chain Replacement Nissan X-Trail
Content
On the Nissan X-Trail, the timing chain needs to be replaced as it wears out. The resource of the chain is much higher than that of the belt, this is a big plus. Replacement is required on average after 200 km.
To determine the degree of wear, remove the cover and inspect the tensioner. The more it stretches, pulling the chain, the greater the degree of wear.
The following equipment is required to replace the Nissan X-Trail timing chain:
- oil pump circuit;
- oil pump chain tensioner;
- crankshaft oil seal;
- sealant;
- seals;
- distribution network;
- timing chain tensioner;
- engine oil;
- antifreeze;
- since the oil filter will also have to be changed during operation, a new filter will be required;
- rags, work gloves, wrenches, screwdrivers;
- it is more convenient to use pneumatic wrenches, which provide high-quality loosening and tightening of bolts and nuts. With the ability to work with this tool, the risk of stripping the thread and twisting the bolts crooked is almost zero.
Many operations require the application of significant physical strength. If a woman is engaged in repairs, then, in principle, one cannot do without pneumatic tools.
Distribution network
Replacing a Nissan X-Trail chain is not half an hour or an hour of fun. We'll have to dismantle almost half of the car. For untrained mechanics, assembly and disassembly takes several days. Proper assembly can take even longer as it requires smoking instructions and familiarity with the service manual.
Preparatory stage
We turn off the power of a hot car, in the standard way, carefully drain the engine oil and antifreeze into pre-prepared containers. Be careful, the oil may be hot. Do not drain used oil into the ground, into tanks, ditches. Taking this opportunity, it makes sense to remove the magnetic trap for metal particles under the bottom of the car and properly rinse and clean with a rag.

Disassembly
You have to remove the right front wheel. Protection, if installed, too. Lockers are removed without problems.
Remove the intake rail receiver and the upper engine mount along with the brackets.
Then the crankshaft pulley, drive belt, attachment tensioners, power steering pump, generator, air conditioning compressor, power steering, exhaust pipe and everything that prevents you from getting to the chain, remove the belts and tensioner.
Very often on the way you will have to tear off the glued joints. Mark these places to fill with sealant during reassembly.

How to remove and replace a chain
When removing the chain, you must first remove the tensioner located on the left. It is fixed with bolts that need to be unscrewed.
After removing the chain, it is strongly recommended to inspect all components for damage, stuck metal fragments, debris, breaks, cracks. Replace all damaged parts. The sprockets need to be replaced.
How to use string tags? The chain itself has the following markings. 2 links are marked in the same color, and one link is painted in a different color.
It is necessary to combine the marks on the intake and exhaust camshafts, the mark of a different color must match the mark on the crankshaft.
Some do the procedure on cats. This is inconvenient and unreliable. The vehicle must be well secured. We recommend using a lift or, even better, a flyover with special supports. It is safer and speeds up the process by an average of 3 times. The lift-mounted machine can be seen from all angles, with full access to the suspension, engine and attachments.
With automatic repair, do not be too lazy to photograph each step in detail. It will be very helpful when reinstalling. Take photos, even if it seems ridiculous and stupid to you, because everything seems completely obvious and understandable.
Distribution network with brands
When replacing the chain, use the Nissan X-Trail timing marks. How to set the marks can be found in the Nissan X-Trail engine service manual. It is necessary to align the marks on the chain with the marks on the camshaft and crankshaft.
The use of a chain is more justified in terms of better handling, reliability and durability of the Nissan X-Trail compared to a belt drive. However, replacing a chain on any Nissan X-Trail model is much more difficult than replacing a belt.

The car will be in a semi-disassembled form, and it is better to carry out repairs in a workshop or a spacious garage.
Question: Is special equipment required?
Answer: Yes, you will need a good professional set of tools and special equipment to remove the pulleys.
Question: What is the savings on auto repair of a car?
Answer: In the workshop for the operation to replace the chain, you will be charged about 10 thousand rubles plus accessories. If you already have the tools and don't make mistakes, you can save that amount, even if it takes a long time. If there are no tools, their acquisition will cost more than the cost of repairs. In addition, tools take up a lot of space and need storage. Best of all in special iron boxes.
Whenever you try to repair a Nissan X-Trail yourself according to the instructions, you must remember that stunt performers and circus performers are people too. They have exactly the same arms and legs as everyone else, which means that everything they can do is within the reach of anyone else. Theoretically yes. In practice, it happens to everyone.
Replacing a Nissan Xtrail timing chain is a technically complex process. More difficult than any skilled person is doing a back flip, for example, or playing the violin. Everyone can. If you study daily, with teachers, in a special educational institution. You will be surprised, but all fitters, turners and locksmiths in a car service have a special education that allows them to perform high-quality car repair work.
If you do not want to take risks, it is better to leave the Nissan X-Trail in the hands of professionals. Non-Professional Repair Repairing an error is often more expensive than simply replacing the required component. For this reason, auto repair videos and instructions are welcome in auto repair shops. Treat video tutorials and car repair manuals with a grain of salt. They are no more effective than any other instructional videos, and you are risking your own expensive property completely of your own free will. By the way, attempts to self-repair a car are not insured events.
On the other hand, you can simply study the subject, so that later, perhaps, you can do car maintenance yourself.
What to look for when reassembling
After completion of the repair and during the process of reassembly, it is necessary to pay attention to the tightness of tanks and connections, pallets, consumables. Otherwise, oil and antifreeze will flow in the car while driving, which usually leads to sad consequences.
When tightening the bolts during assembly, do not forget to lubricate them with grease.
Some parts can only be rotated in one direction. Therefore, the crankshaft cannot be rotated counterclockwise.
