Presentation... service on Kashirskoe shosse • ​​Presentation of the Land Rover LR VES service... In this video, using the example of a Range Rover Sport in the L494 body (2014-present), we told you everything about the timing chains of 5.0 Supercharged and 3.0 Supercharged engines. The information will be absolutely identical, so in the following text we will resort to 5.0 Supercharged. As you have already understood from watching this video, even if your Range Rover or Range Rover Sport is already of the next generation, namely L405 or L494, this does not mean that you have new-style chains installed! In our case, the situation is when the Range Rover Sport 2014-2015 with a 5.0 Supercharged engine, on which old-style chains are installed, and you have become a piper. The mileage of this Range Rover Sport is approximately 80,000 km. Decide for yourself whether it is a lot or a little, but as service practice and many years of experience show, after installing an upgraded set of chains, the replacement is not performed again. The new timing chain set for 5.0 Supercharged and 3.0 Supercharged differs in that the chain tensioners have a metal heel (rivet), which prevents excessive pressing of the metal, and the timing chain tensioners themselves have a different angle of applied pressure. The chains have not undergone any changes, but be that as it may, they also stretch and need to be installed new ones. Features that you should know about when replacing timing chains on a Range Rover, or rather what else may be required during this type of work. Water pump. It may have excessive play in the pulley shaft bearing or even leak along the body, which will indicate a violation of its tightness. In this case, when replacing the timing chains on 5.0 Supercharged and 3.0 Supercharged, it is better to install a new water pump for the cooling system. Drive (nose) Supercharged The spring-insulator, which is installed in it, breaks and when the supercharged air compressor is running, you can hear an extraneous and quite spectacular rumble, which can, let's say, scare you. In this case, the manufacturer offers to install a new compressor drive assembly, the cost of which is from 30,000 rubles to 50,000 rubles. LR-West offers a different solution to this problem, realizing that the causal spare part is the spring-insulator. Having taken all the necessary dimensions, we ordered the production of couplings that not only solve the problem with the Supercharged drive, but also allow you to reduce the cost of expenses by 5-7 times. Oil nozzle The oil nozzle that supplies oil to the crankshaft sprocket is a new model, which has been modified in geometric shape due to the fact that the previously installed one was simply knocked off by the chain. When replacing the timing chains on a Range Rover, pay attention to this and, if necessary, install a new oil nozzle. Fuel injection pump shaft chain tensioner When replacing the timing chains on a Range Rover, also pay attention to the third chain tensioner, which also comes in a new model. Its modification consists of an additional casting on the plastic housing, which prevents the spring from jumping off. You can easily and simply distinguish between tensioner samples. In the very bottom line of the inscription on the tensioner housing itself, the designation CB means the old model. CC is a new model. It is humane to install a new third chain tensioner when replacing timing chains on 5.0 Supercharged and 3.0 Supercharged. Synchronization of the injection pump drive shaft When replacing the timing chains on a Range Rover, it is also necessary to check the synchronization of the injection pump drive shaft and the vacuum pump for synchronization. It can go out of sync for various reasons, but its synchronization is performed using an original special tool. The injection pump and vacuum pump drive shaft must be set to the marks, otherwise during subsequent operation of the Range Rover, there is a high probability of incorrect operation of the fuel system and unstable operation of the 5.0 Supercharged and 3.0 Supercharged itself. Timing phase shift clutches Cutting out the teeth of the timing clutches is not a reason or subject for their replacement. It is most likely impossible to say that after installing the clutches you will achieve a quieter engine operation. Timing phase shift clutches must be changed only in fact and in the presence of their internal malfunction. Thank you all for your attention and good luck on the road!
