As a collection of tens of thousands of parts, a car is constantly exposed to movement and vibration during use, and it is sometimes said that it needs to be “break in. Many people have heard of “engine break-in”, where the engine is run at a low RPM for a while, but it is a little known fact that there is a similar break-in process for suspensions as well. In this article, we will discuss “breaking in the suspension”. Is it necessary to break-in the suspension? There are pros and cons regarding the need for suspension break-in. However, as it turns out, the suspension needs to be broken in. The suspensions of mass-produced cars are subject to a small amount of error. Therefore, even if the suspension is 100% complete, some amount of driving is necessary before the matching is completed in the assembled state. Therefore, it is necessary to break-in the suspension. In particular, it is a good idea to break in the suspension when you have replaced the stock suspension with an external suspension or dampers. Break-in of the factory installed suspension Some people believe that the factory-installed stock suspension does not need breaking-in, but the stock suspension […]
I knew that there was some play in the idler pulley before, so I changed the alternator and then replaced it as well. Idler pulley genuine product. Part number: 11927-VC800 It’s easy to replace. Loosen the nut in the center to free it, so use the adjust bolt below to raise the pulley and remove the belt. After removing the belt, lower the pulley to remove the nut, remove the washer inside like a lid, and remove the pulley. The bearing of the old idler pulley that I removed was still loose. Installation is completed easily in the reverse procedure. Since the bearing is quite loose with respect to the shaft, the backlash is not completely eliminated. I think that it is better to replace the shaft if it seems that the backlash is too bad even if it is replaced. Since this belt only drives the air conditioner compressor, adjustment is completed with moderate tension so as not to overload. It was easy to finish, so I tried “Isn’t it cheaper to replace only the bearins?” From the result, it seems that it is impossible to use hand-held tools. The board was thin, and it was probably baked in, […]
At the time of vehicle inspection, it was pointed out that the power steering belt may be loose and worn, so I checked it. Loosen two fixing bolts to move the power steering pump. First, align the hole of the pulley on the back side of the pulley with the bolt, and insert a 14 mm box wrench. The radiator shroud is an obstacle, but if you press it, it will dent, so I will manage to thrust it. The second can be reached by pushing the box wrench from the bottom of the pulley and from the side. If you loosen the two fixing bolts, the pump will be free, so you can adjust by moving the adjust bolts indicated by the blue arrows. I think it was loosened by turning left and tensioned by turning right. It was easier than I expected, so I took off the belt and inspected it carefully. The ridges of the belt seem to be slightly worn, but there are no cracks at all, so I will reuse it. I would like to change it to a reinforced product such as HKS, but since it can be easily replaced, I will not waste […]
The bare type air cleaner has the problem of sucking hot air. I thought that I wouldn’t mind if I was running with a duct for guiding the wind. However, looking at the ECU data and logs, it was found that even during high-speed cruising, air with an outside temperature of + 20 to 25 ° C was inhaled. In the intake air temperature correction, when the temperature rises by 20 ° C, the fuel is thinned by about 4%, so it cannot be overlooked because the loss is -4 horsepower at 100 horsepower and -24 horsepower at 600 horsepower. When I investigated why breathing hot air, the wind that hit the engine was heated by the fan and diverted to the side, hitting the air cleaner directly. As a countermeasure, we will make a heat shield. Mold with thick paper. I had a sheet metal shop in my neighborhood make it. Aluminum, which is easy to process, is good for DIY, but since it can be cut by a machine, I asked him to make it with a stainless steel plate. I made some adjustments and did some processing myself, but stainless steel is hard to scrape anyway! Aluminum […]
Recently, intermittent fuel injection during engine braking has recurred. I thought it might be because I had fixed it when I turned off O2 feedback before, but it seems different. There is also a flutter when the accelerator is suddenly stepped on, and it seems that the deterioration of the sensor is the cause when examining various things. Part number: 22620-05U01It’s a reasonable price of $ 50. Is it because it is also used in other models? This sensor has the following two functions, and the coupler on the main body side is the throttle valve switch. ・ Throttle sensor (voltage change due to throttle amount)・ Throttle valve switch (ON / OFF switch for idle judgment) First of all, the hose is an obstacle to turning the bolt, so pull it out. Remove the bolt by turning it with a 7 mm spanner or a + screwdriver. Remove the coupler on the main unit and the coupler with the cable. The coupler on the main unit has a pin to prevent it from coming off, so remove it. You can see the shaft by removing the sensor. There is a notch so you can see it when installing. There is […]
First of all, don’t forget to protect the mating place with curing tape. And recommend working with two people. Remove the 5 clips (all are not shown) indicated by the yellow circles and remove the panel. Remove the clip indicated by the yellow circle and remove the interior of the trunk. Do this for both sides. Also remove the floor mat. It is not fixed. Remove the nut indicated by the yellow circle. Remove the coupler indicated by the right arrow. Push the grommet indicated by the left arrow to the outside (bumper side). Do this for both sides. Remove the clip indicated by the circle on the rear tire house. Do this for both sides. Remove the cover of the tire house,and remove the nut that secures the rear under and bumper. The bolt fits into the hole in the rear under, so remove it. Do this for both sides. Remove the clips and nuts indicated by the circles on the left and right, and remove the diffusers on the both side. Although it is not shown in the photo, remove the clip that holds the center diffuser and rear under, and remove the rear under. The side can […]
It has been 13 years since the Nissan R35 GT-R was released. Since the initial model (2007–2009) has a large number of sales, the price of used cars has decreased. There will be more and more people who purchase second-hand cars and become new owners, or purchase as a base vehicle for tuning. So, for those who will be the owners of the future, as one of the 2008 model owners, I have summarized the problems that have occurred in my GT-R so far. The LED lamp behind the meter went out About 28,000 miles (about 3 years) later, the LED on the fuel gauge gradually began to blink, and at the end it completely disappeared. I had no problems in driving, but I replaced it because other lamps may go out in the future. I was lucky enough to be able to fix it with the manufacturer’s warranty. By the way, it is said that there is no report of trouble after it became the blue color meter of the current model. Looseness of the flywheel housing Familiar defects in 2007–2009 models, loose flywheel housing. When the mileage was about 57,000 km, it started rattling at high speeds, so […]
I’ve always been concerned the gap of front bumper. So I decided to fix it cheaply. There is quite a gap between the headlight and the bumper. This bothers me. This is the parts I will use here. – bolt(M6×120㎜)– high nut(M6×30㎜)Both are made of iron. You can get them for about $5 at home improvement center. Then carrying out. Attach the previous one to the bolt at the red circle. It comes out from the car body side and is fixed with a nut. First of all, take the stay fixing the bumper. You cannot install the bolt without removing this. Let’s install the bolt. I don’t think there is a problem without it, but it would be good to have a spring washer to prevent it from loosening. I think there are various ways to adjust it, but I adjusted it while lifting the bumper. I think that there is no problem if you adjust with your own method. Adjustment is complete. The gap of the bumper has disappeared successfully. As a precaution, keep in mind that if you raise it too much, the hood will not close. By the way, this time I dropped the bonnet from […]
