- Q:where is the shuttle valve located in 03 land rover discovery hse ?
- The shuttle valve is a part of the brake modulator this problem is addressed by the replacement of the brake modulator and that's a $1,500.00 dollar part plus labor but I believe that they sell a shuttle valve repair kit for around $100.00 dollars.....
- Q:I recently converted my furnace from l.p. gas to natural gas. It's been maybe two weeks of me troubleshooting and replacing. I have a new gas valve and transformer in the furnace. There is 24v running to the valve and it clicks to open but no gas comes out. I have exhausted all my options with the mechanical/electrical components on the furnace. I have bled the valve to be sure that there was gas making it to the inlet side. Does anyone have an idea as to why the valve stopped opening once I converted it over?
- may sound like a stupid answer but there is an arrow on the bottom of the gas valve and i have seen them put in backwards,or it sez inlet on 1 end,,make sure the knob is turned to on,make sure the arrow is pointing towards the burners
- Q:I have an old trumpet valve stem that will not screw in the valve cap. I ordered a new one but I'm not sure how to remove the old one and put the new one on without doing anything that would influence the look and playing. HELP!!! Professionals are welcome and others. I don't have any professional technicians near by .Summer band is starting up so I need this FAST.
- I hope you have a Bach trumpet, because each valve stem is specific to a particular maker and even to specific models. So, if you don't have a Bach trumpet it is very likely that the stem won't fit. If you cannot remove the valve stem with your hands you can try soaking the joint with oil and/or warm water and dishwasher detergent. You should give yourself a couple of days to see if you can loosen them up. Do not use tools--no screwdrivers, no pliers, no vices, no strap wrenches--if you don't know what you're doing you stand to damage the very fragile valve. You may need to take it to a tech--remember you're trying to avoid a $100+ dollar bill for repairing a damaged valve.
- Q:My sump pump shut-off valve is very noisey. I wrapped insulation around it, but it still clunks. The clunk can keep me awake.
- Silent Sump Pump
- Q:I have a 40 year old Holton Bb trumpet. It plays fine except the first valve always gets stuck when I play it, in the middle of a song it won't come back up. I can pull it back up and it doesn't get stuck real bad, but how can I fix this? I always oil it properly and insert the valves right. Do I have to replace it? Thanks
- You need not replace the valve, but it does need a bit of attention. There are many possible reasons for the sticking and you can spend a long time trying to chase them down. Inconsistent sticking suggests 2 likely reasons (there are several more possible reasons). The first is piston wear that has slightly misshapen the valve casing so it sticks because it doesn't travel through the valve casing exactly the same way every time. The second is that the felts and corks are worn and need to be replaced. The best thing for you to do is to take it to a shop, describe the problem and spend a few bucks to get it fixed right.
- Q:This trumpet has been in storage in its casing untouched for about 5 years. I took it out and tried to play it but only air comes out and no sound. The 2nd and 3rd valves are hard to push down. What do I do to fix it? Thanks!
- Dis is a pretty common problem. The valves are in the wrong valve case or they are turned aound in the case. Take each valve out and check the number...... most have a number stamped near the top, or on the part around the spring. Get them in the right place with the notch in the case matching the little peg on the side of the valve and all should be well. By the way, if you can't get a buzz on the mouthpiece the whole problem is you alone.
- Q:Hey my sexy internet homies lt;3: I need help on artificial valves. I need to know the following things:How do the properties of the materials artifical heart valves are made from make them useful?Explain how the structure of the technology is related to the function that it needs to perform.Thanks!!
- There are three of these things: the caged-ball which utilizes a metal cage to house a metal ball, tilting-disc valves, which have a single circular occluder controlled by a metal strut. They are made of a metal ring covered by a tissue, into which the suture threads are stitched, in order to keep the valve in place once implanted and there's bileaflet valves, which consist of two semicircular leaflets that rotate about struts attached to the valve housing which is the most recent type, eh? So heart valves are considered to be extremely durable. They're made of either pyrolytic carbon or titanium coated with pyrolytic carbon, and the sewing ring cuff is Teflon or polyester or dracon (probably dacron :P). They key to the materials chosen is durability because of the constant fluid flow. I see this as pure engineering, not medicine, specifically fluid mechanics: like if there are rare complications for example thrombus formation is a debilitating side effect of high shear stresses created by design of the valves. Ideal heart valve from an engineering view would produce minimal pressure drops of course have small regurgitation volumes because it's supposed to minimize turbulence and regulate the flow.
- Q:1990 Pontiac Sunbird, I took a piece of hose going to the egr valve to try and see if it is working properly, but with car off, I can suck through, and blow out into hose going to egr valve, and it doesn't seem like there's any seal stopping air flow either way...is it supposed to, or what is this supposed to do?
- won't be able to help precisely yet this is a image of it so do the the place's waldo with this hyperlink. it is in lots of situations linked to the intake manifold the PCV is on the valve conceal and all vehicles from approximately seventy 8 on have EGR's
- Q:There has been brake fluid leaking below where the Master Cylinder was and pinpointed that the leak was at the base where the steel lines and proportional valve intersect(kinda sprays out out like if a seal is bad or someone didn't tighten enough). Any way to fix this or replace? Vehicle is a 1988 Plymouth Reliant (2.2 liter) Auto, no ABS.
- no count number if it incredibly is a proportional valve a 24 volt supply won't supply proportional administration. to boot, controlling an inductive load with a persevering with voltage slows the reaction time.
- Q:how to replace a valve cover gasket on a 98 pontiac sunfire 2.2. engine?
- First off, you remove the PCV hose and unscrew the plastic nut that retains the PCV valve. Next you remove the air intake tube from the throttle body and the air intake housing. Now locate the bracket on the side of the throttle body that contains the throttle cable. Remove the 2 bolts from this bracket and remove the cables from the throttle body. You should now be able to remove the valve cover from any obstructions. If you are not cleaning the valve cover, there is no need to remove the PCV valve. If you are cleaning it with soap and water, take the PCV out. The gasket is one piece and rubber, but you may find it a pain to keep the gasket in the groove on the valve cover, so you might try some yellow weatherstrip sealer to help hold the gasket in place. Let it dry for a little while before reinstalling the valve cover, so the gasket doesn't 'roll' out of the groove on the corners, or it will leak heavily. Good luck.
