Newer Navara D40 models are fitted with single timing chain drive. Although these timing chains should last the life of the truck or at least 100K miles but the weak single chain design snaps at about 40-60K miles. This is a common fault and replacement timing chain kit needed. Unfortunately D40 Navara single timing chain drive will wear off the twin cam chain gear then the chain goes off each cam. If you have the single timing chain on your Navara D40 then you should listen to the rattling noise that the engine gives at start up. If the timing chain is not rattling then it is not stretched and doesn't have to be changed. When a timing chain is rattling then it is stretched and no longer under tension. Should be replaced. The chain tensioner try to keep the chain tensioned but it also should be changed at about 40K miles. Our Navara D22 timing chain replacement has duplex chain drive. Although it is older but it is more reliable than the newer D40 models.

When you need to change your timing chain?

* After 100K miles (advised by Nissan)
* If you noticed rattling noise on start up
* If your D40/R51 engine cuts out after some time. In this case you will most likely have a stretched chain.

How to make sure that you have a stretched chain?

1. Unplug your camshaft sensor (NOT the crankshaft sensor and DON NOT remove the camshaft sensor! Just unplug it, disconnect it.)
2. Try to run your engine, use it without camshaft sensor being connected
3. If the problem persist try to investigate further. (Change SCV valve, crankshaft sensor, ECU etc.)
4. If the engine cut out seems to be resolved after disconnecting your camshaft sensor then you have a stretched timing chain and it is due to be changed.

Also is the engine gets scratchy on startup or it becomes hard to start and would stop dead under 1000rpm then most likely you have a stretched timing chain.

D40 2006-2010 (Euro 3-4)

Navara D40 and Pathfinder with YD25DDTi engine up to 2010. Euro 3 and Euro 4 engine.
If you select this option then you will get an additional duplex conversion sprocket which fits your original D40 vacuum pump. IT DOES NOT REQUIRE YOU TO MODIFY YOUR ORIGINAL VACUUM PUMP! Our German made sprocket will fit the original shaft so it is very easy to fit. (The duplex chain upgrade sprocket is INCLUDED this option!)
In this option your newer (2006-2010) stock simplex timing chain will be converted to a durable duplex chain system.
In this option we include a timing cover gasket and two essential O-ring seals.

Quality: German aftermarket quality (see below pics).

If you select this option you will get all parts included above in (D40 2006-2010) option + additional parts to be able to fit the duplex upgrade to your Euro 5 engine.
(Please note that timing cover gasket is NOT included with this option!)

Japan aftermarket product.

Although the German aftermarket option fulfils most customers' expectations we always recommend to choose the Japanese aftermarket option. Our Japanese  timing chain kit supplier is much longer on the market and their products are proven to be superb quality. If you select Japanese option you'll still receive 1-2 German parts inside the kit depending on which Navara/Pathfinder R51 model you have. Euro 3-4 or Euro 5. The reason for getting some German parts within Japanese kit is that some parts for duplex timing chain upgrade have been developed and manufactured only by our German supplier.

Alternator clutch pulley.

Other common problem with Navara D40 and Pathfinder is the alternator pulley. It is highly recommended to change when you change your timing chain. If you opt it then you'll receive a genuine INA alternator pulley.

Alternator belt.

It should be changed if you do the chain job. If you opt it then you'll receive a genuine Contitech alternator belt. 

Water pump

It is recommended to change water pump when you do a timing chain change.

Vacuum pump bearing

With our timing chain kit you don't need to remove the engine, remove the vacuum pump just to change its shaft like other cheaper alternatives. Our kit offers a hassleless timing chain upgrade without modifying your original vacuum pump but if you still want to change the vacuum pump bearing then you can tick this box. 

Transfer box seal

Other common problems with Navara D40 and Pathfinder R51 is the rear/output seal of the transfer box. The transfer box switches fail due to moisture coming in from that seal. It is recommended to check and change this seal when you do a chain upgrade. Please note that replacement seal (including genuine) will fail shortly due the developed groove in the shaft by the old seal.  If you just simply replace this seal it will not solve the problem as the oil will still leak under the groove. Alternative solution is to get a new half shaft which can be expensive or just use our double lip shaft seal. These lips will run on a different surface and the problem is permanently resolved.

With genuine Nissan upper AND lower chain + upper tensioner (on request only for additional cost)

With these high-performance engines the lower timing chain is the weakest and the most important part of the timing. It is recommended to select this option as the genuine Nissan upper and lower chain last longer. 
If you tick this option whichever timing kit you choose we change the upper & lower timing chain to genuine OE Nissan chains + a genuine upper chain tensioner.

Competitors online:

There is paid sponsorship available on nissan-navara forum. On their forum you will find no other alternatives to these Navara duplex chain conversions apart from & . Don't expect others since they (including moderators) run the forum.

You may also want to ask why is that no other qualified mechanics are never recommended on the forum? It looks like United Kingdom have only 2 recommended mechanics. and . Odd isn't it? Moderators are all extremely helpful when they need to recommend the forum sponsors' names.  

You may find comments on these forums where they try to explain that stripping down the vacuum pump and swap the sprocket and shaft (extra 1-2 hours labor) is actually better than using a newly developed duplex sprocket which requires NO extra job. This makes sense only to those who actually try to sell their parts & services and of course to the forum sponsor moderators.
These forum moderators try to generate sales for the forum sponsors with their comments and let you pay for the extra labor to your mechanic. Think twice before you give credit to those comments.
