Unfortunately, I didn't find any torque specs for its bolts in the manual. Water Pump Pulley Bolts----------------------------------17 – 18 I question this! Location: Tacoma WA. Torque specs for thermostat housing and urban development. Reinstall plug in t'stat housing. Applies to screwed joint with strength class readTightening torques (Nm)M5 5 M6 10 M 7 17 M8 24 M10 50 M 12 80 M 14 130. Last edited by ES6T; 09-19-2018 at 08:40 PM. Does anyone know the torque value for the two bolts on the thermostat housing (the plastic neck piece on the coolant return hose).
Housing gasket as I remember is flat. All bolts were new from Toyota and all broke at the same spot with approximately the same amount of force applied. I noticed the other day that a small amount of coolant was sitting on one of the studs above the nut. To that effect, why are you using a torque wrench for 14lb torque value? As you can clearly see from Vida: " Note! Time Change This Sunday! I always inspect the o-rings and have never found one to be broken or even brittle. Replacing thermostat today, whats the torque specs on the bolts. It's nice to have though. Does anyone have the torque specs for the 2 thermostat bolts?
1999 4runner Highlander (Manual). Volvo now recommends Wurst super silicone for those applications and gaskets and or gasketless surfaces such as the transmission valve body cover and other places. Chevy 350 thermostat housing torque. 1990 4runner 4wd Auto V6. Do you think anyone in the real world is going to quibble about a difference of 5nm? Yup, searched a few threads for the torque specs for the 2 bolts that bolt down the thermostat housing and could find everything but the specs. If those bolts are only 10 or 12mm then the housing is likely smaller and more delicate than I have envisioned (I have not put my dirty fingers on it yet).
I agree, 14 ft-lbs isn't exactly a herculean amount of force and should be pretty straight forward. I watched a professional do it one day. I can see maybe needing to cut the handles off to get them in tight spaces. Not necessary to tighten more than that. Thermostat housing torque specs. Please change the text in the following Service Manual, page 66, section L3, from one gasket to two gaskets. What is more important is that they are good bolts to start with, that the mounting surfaces of the housing and the intake are smooth and that you tighten them evenly. Here it is for the rear wheels: Volvo calls this procedure "Angle-tightening, " all other bolts are simply referred to as using the correct torque.
I made certain the mounting surface was true with a flat file on both the intake and the housing. I'm being forced to rebuild/clean my duo-valve because it's decided to become super-sticky in the last few days. I told him that I think it's supposed to be 180. Last post by gibbi42. Then the lower housing cracked at a torque of less than 15 ft-lbs. I just tightened by feel then, I am wondering if I didn't squish the oring gasket. Torque specs for thermostat housing bubble. The sensor which comes as part of the housing kit now, fails as well. There was a thread on torque settings only 2 days ago but 10 seconds on Google with 'MGB torque settings' will produce any number of hits with that information. Remove plug in top of t'stat housing. 6L JK engine, the torque in question is 106 in/lbs, according to the 2012 JK service manual. You may not edit your posts. 1993 Nissan 300zx Twin Turbo. What do I have to torque the bolts on the housing down to?
Aftermarket or AISIN water pumps frequently come without new bolts. I'm thinking 18ftlb (ish). Strut to Tower----------------------------------------------------24. It's a 3/8" drive with 10-75lbs range. Torque setting for thermostat water neck bolts. Despite offering advice, the individual insists on the factory published torque and argues with everyone that tries to help. So do yourself a favor find out if your particular housing kit comes with new bolts, gaskets, or if aftermarket, needs some sealant or not, but change everything, over time it makes a difference if your going to keep your Volvo. The higher grade HF stuff is supposed to be pretty good. Or show me where the parts catalog indicates the thermostat housing comes with new bolts.
I reused the existing bolts, I usually do not. It was worse before I changed it again this last weekend. Hope this helps you further. FWIW, I have a redblock reference (e. g. 240's) with 11-15 ft*lb for the spec, so that's probably a safe range. If it is leaking you probably should replace it.
35 ft lbs is 47 Nm, if you do that the bolts will either break or strip the aluminum. Gonna take a stab and say something was wrong with the studs already in some way. Last post by Ejbdunes. 5 ft-lbs); I may default to those if no one has a different number, but that feels a bit light to me. Need thermostat housing and intake manifold help! ICON came out ahead in terms of consistency and accuracy. Screws coated with a locking fluid or self locking nuts must be replaced with new when reinstalled. " At least steel bolts are used so they can be removed, Al can be retapped and a slightly larger bolt on that starting here by one of our members - although it's the water pump, not the thermostat, it's still the same concept (steel threads into aluminum casting, and either too much torque or crud or both): Something many dealers don't pay for BTW. I'd just get it good and snug with a star pattern and call it good. Not with 3 new bolts, no way.
04-24-2021, 04:11 PM. I just purchased a Volvo pump over the counter AISIN WPV-800 ((manufactured by Aisin)), it did not come with bolts, I expected that it would. Vida BTW is full of contradictions, this is why factory training is important. Knowing this will make a big difference in the answer given.
I was in a hurry, call my a hypocrite. ) Nothing like gingerly rotating them back and forth, little by little as you feel the crunchiness. The intake manifold is tightened to 20nm, again new bolts, (locktite. ) Sent from my iPhone using Tapatalk. This can also be done with the engine off by pulling the highest heater hose. Mine has been on and off a few times over the last 2 years (to change thermostat and put in a restrictor). I have searched high and low and have not found it. 3 members ( fattboyzz, 3800GUY, 1 invisible), 74. guests, and.
Control Arm to Knuckle Nut & Bolt--------------------------29. Grandpa always said to "stop tightening well before it starts getting looser". Haven't been there in years but I still use some Pittsburg tools I got ages ago when my only vehicle was a quintessential poor guy Suzuki Esteem, which was an amazing beater car tbh. Or this sealant you claim it calls for. Don't want to break them off after replacing thermostat, gaskets, and water pump. This is just one reason your dealers labor rate is 2x any independent shops, it is expected that all new fasteners and gaskets are to be used, ultimately for reliability, and dependability.
Location: Florida and/or Raleigh NC, depending on the day. Of course if your like so many and just want to get it out of the "shop" and get it to last 30 days,.. do what ever you want as so many do. And just tightening them is enough. Shogun - thanks for the feedback, this helps. The intake uses M7, which are 17Nm.
Again, they move away from the point where they combine as if they never met each other. Figure 16-44 shows the displacement y versus time t of the point on a string at, as a wave passes through that point. Sometimes you just have to test it out. Waves that appear to remain in one place and do not seem to move. So if I overlap these two. As the earthquake waves travel along the surface of Earth and reflect off denser rocks, constructive interference occurs at certain points. Here, is displacement, is the amplitude of the wave, is the angular wave number, is the Angular frequency of the wave, is time. Q31PExpert-verified. Typically, the interference will be neither completely constructive nor completely destructive, and nothing much useful occurs. Frequency of Resultant Waves. So the total wave would start with a large amplitude, and then it would die out because they'd become destructive, and then it would become a large amplitude again. Moreover, a rather subtle distinction was made that you might not have noticed.
From heavy to light, the reflection is as if the end is free. Your intuition is right. As we keep moving the observation point, we will find that we keep going through points of constructive and destructive interference. There may be points along the resultant wave where constructive interference occurs and others where they interfere destructively. The following diagram shows two pulses interfering destructively. On the one hand, we have some physical situation or geometry. Then visually move the wave to the left. If the amplitude of the resultant wave is twice as likely. Navigate to: Review Session Home - Topic Listing. Let me play just a slightly different frequency.
If 2x happens to be equal to l /2, we have met the conditions for destructive interference. If the amplitude of the two waves are not equal, than the overall sound will vary between a maximum and a minimum amplitude but will never be zero. For a pulse going from a light rope to a heavy rope, the reflection occurs as if the end is fixed. 18 show three standing waves that can be created on a string that is fixed at both ends. When the end is loosely attached, it reflects without inversion, and when the end is not attached to anything, it does not reflect at all. The result is that the waves are superimposed: they add together, with the amplitude at any point being the addition of the amplitudes of the individual waves at that point. If the amplitude of the resultant wave is twice as old. Here, the variable n is used to specify an integer and can take on any value, as long as it is an integer. Keep going and something interesting happens. Describe the characteristics of standing waves. How do waves superimpose on one another? The basic requirement for destructive interference is that the two waves are shifted by half a wavelength. You may have noticed this while changing the settings from Fixed End to Loose End to No End in the Waves on a String PhET simulation. Wave interference occurs when two waves, both travelling in the same medium, meet.
That's what this beat frequency means and this formula is how you can find it. So you see this picture a lot when you're talking about beat frequency because it's showing what the total wave looks like as a function of time when you add up those two individual waves since this is going from constructive to destructive to constructive again, and this is why it sounds loud and then soft and then loud again to our ear. Two interfering waves have the same wavelength, frequency and amplitude. They are travelling in the same direction but 90∘ out of phase compared to individual waves. The resultant wave will have the same. If the speakers are at the same position, there will be constructive interference at all points directly in front of the speaker. Part 5 of the series includes topics on Wave Motion. The given info allows you to determine the speed of the wave: v=d/t=2 m/0. Given a particular setup, you can always figure out the path length from the observer to the two sources of the waves that are going to interference and hence you can also find the path difference R1 R2.
In general, whenever a number of waves come together the interference will not be completely constructive or completely destructive, but somewhere in between. Lets' keep one at a constant frequency and let's let the other one constantly increase. Which of the diagrams (A, B, C, D, or E) below depicts the ropes at the instant that the reflected pulse again passes through its original position marked X? The standing wave pattern shown below is established in the rope. Displacement has direction and so when added the two cancel each other out. If the amplitude of the resultant wave is twice as great as the amplitude of either component wave, and - Brainly.com. For example, water waves traveling from the deep end to the shallow end of a swimming pool experience refraction. All these waves superimpose.
All sounds have a vibrating object of some kind as their source. The resultant wave from the combined disturbances of two dissimilar waves looks much different than the idealized sinusoidal shape of a periodic wave. Here we have to use the wave equation for the 1st wave using equation (i), we get. If the amplitude of the resultant wave is twice as great. Consider one of these special cases, when the length of the string is equal to half the wavelength of the wave. At the boundary between media, waves experience refraction—they change their path of propagation. What the example of the speakers shows is that it is the separation of the two speakers that determines whether there will be constructive or destructive interference.
The resultant wave will have the same. For this reason, sound cannot move through a vacuum. To start exploring the implications of the statement above, let s consider two waves with the same frequency traveling in the same direction: If we add these two waves together, point-by-point, we end up with a new wave that looks pretty much like the original waves but its amplitude is larger. The principle of linear superposition applies to any number of waves, but to simplify matters just consider what happens when two waves come together. Pure destructive interference occurs when the crests of one wave align with the troughs of the other. The reflected wave will interfere with the part of the wave still moving towards the fixed end. "I must've been too flat. " It is just that it is too hard to time it right, unless a computer can play 2 equal tones with a set phase interval between them. Answers to Questions: All || #1-#14 || #15-#26 || #27-#38. Translating the interference conditions into mathematical statements is an essential part of physics and can be quite difficult at first.
However, the waves that are NOT at the harmonic frequencies will have reflections that do NOT constructively interfere, so you won't hear those frequencies. This is why the water has a crisscross pattern. So that's what physicists are talking about when they say beat frequency or beats, they're referring to that wobble and sound loudness that you hear when you overlap two waves that different frequencies. Tone playing) And you're probably like that just sounds like the exact same thing, I can't tell the difference between the two, but if I play them both you'll definitely be able to tell the difference. What would happen then? The two previous examples considered waves that are similar—both stereo speakers generate sound waves with the same amplitude and wavelength, as do the jet engines. Hence, the resultant wave equation, using superposition principle is given as: By using trigonometric relation. Because the disturbances add, the pure constructive interference of two waves with the same amplitude produces a wave that has twice the amplitude of the two individual waves, but has the same wavelength. 667 m. Proper algebra yields 6 Hz as the answer. Here again, the disturbances add and subtract, but they produce an even more complicated-looking wave.
This refers to the placement of the speakers and the position of the observer. Again, R1 R2 was determined from the geometry of the problem. I have a question: since the wave travels up and down, what does it mean when the distance from the midline to the trough is negative? Constructive interference, then, can produce a significant increase in amplitude. Let's say you were told that there's a flute, and let's say this flute is playing a frequency of 440 hertz like that note we heard earlier, and let's say there's also a clarinet. So, if we think of the point above as antinodes and nodes, we see that we have exactly the same pattern of nodes and antinodes as in a standing wave. The two special cases of superposition that produce the simplest results are pure constructive interference and pure destructive interference. We've got your back.
When there are more than two waves interfering the situation is a little more complicated; the net result, though, is that they all combine in some way to produce zero amplitude. In addition, the High School Physics Laboratory Manual addresses content in this section in the lab titled: Waves, as well as the following standards: - (D) investigate behaviors of waves, including reflection, refraction, diffraction, interference, resonance, and the Doppler effect. This is called destructive interference.
