Vacuum Brake Booster Testing and Diagnosis Vacuum Brake Booster Testing and Diagnosis This procedure will require the use of a hand operated vacuum pump with a vacuum gauge. If you do not own one it can often be rented or borrowed from most “big box” parts stores. (Note: 18”HG is the minimum engine vacuum at idle in gear to effectively operate a vacuum booster 1) Remove vacuum hose from check valve on booster. Place hose from vacuum pump onto check valve and draw booster to 20” of vacuum. 2) Let booster sit with vacuum applied for 5 minutes. If vacuum does not stay steady at 20” it is faulty and needs to be replaced. If vacuum does hold steady at 20” proceed to step 3. 3) With 20” of vacuum in booster depress brake pedal once and release it. The booster should transfer some but not the entire vacuum in reserve. Depending on how hard the pedal is depressed it is normal to see 5-10” of vacuum depleted from reserve. The most important thing is to ensure the booster does transfer vacuum but does NOT transfer the entire vacuum in its reserve. If vacuum remains at 20” OR goes to zero the booster is bad and will need to be replaced. If vacuum transfer is within the above parameter proceed to step 4. 4) Once again draw booster down to 20” of vacuum. Go inside car and depress brake pedal and hold down for 30 seconds. You should see the gauge drop slightly and then hold steady. Vacuum should stay steady as long as you are holding the pedal down. If vacuum drops while pedal is being held down the booster is faulty and will need to be replaced.

Referred to as the Town of Angels, La is well-known around the world because of its films, lively tradition and luxurious lifestyle. In 2007, more than 61 million people moved to and from Los-Angeles airport poor, testifying for speed and the plain draw of the town.
INSTALLATION INSTRUCTIONS Location 1. The fireplace may be hanged on any wall surface that can support its weight and where it can be leveled. As it does not irradiate any heat from the back and no rear clearances are needed. 2. The heater, which is located at the base of the fireplace, must be a minimum of 16 inches away from any combustible material. 3. It is important that the wall on to which the fireplace is to be installed is of sound construction. It is recommended that the brackets are installed directly into beams for support. But not necessary depending on the size and weight of the unit. 4. Yosemite fireplaces are approved for indoor use only. 5. The fireplace must be kept away from any source of damp or moist conditions. Avoid any close contact with water. 6. This fireplace produces heat. Consequently it is important to ensure that a suitable wall covering is selected behind and around the appliance. Typical wood frame drywall construction is suitable. 2|P a g e Installation Figure 1 1. Select the position of the fireplace on the wall to which it is to be mounted. Draw a level horizontal line on the wall at the required height. This line will correspond to the top of the fireplace so it is important to allow for the extra height of the glass face. 2. Mark the center line of the fireplace on to the horizontal line. 3. Place the Installation Plate along the horizontal line and line up the center “V” cut out with the center line. See Figure 1. 4. DRYWALL INSTALLATION Install screws into studs at 4 outside corner screw holes. If studs are not present, install self drilling hollow wall anchors at the 4 outside corners and find wood studs with at least 4 more screws on the mounting plate (two high and two low). Holes are offset to allow finding wood studs at normal spacing. Attach more screws into larger models as needed.
The new SolidWorks Electrical 2D is powerful software that includes all the functionality required for electrical engineers to complete their projects. It allows you to work and collaborate easily on several electrical projects simultaneously, create comprehensive single or multi-line schematic diagrams, generate automatic reports and bills of materials, and even include manufacturing information or instructions. The line drawing planning tool, for example, provides innovative capabilities and can be used at any stage of the development process. With a large library of symbols, it allows designers to create simple yet powerful representations of the electrical wiring that are perfect for project management and reporting. You will also benefit from the extensive database of manufacturer parts that are updated frequently and available within the software. This allows you to search, find, and add the right motor, contactor, or any other electrical component when designing the electrical system. Using simple tools, you can draw and define connections between the components regardless of where they are in the design. In addition, cables or wires can be assigned even at this stage using the cabling window. After adding some terminals and selecting the right cable from the cable repository, you can assign its conductors as connections between electrical components. But, more importantly, it’s also linked automatically to the traditional detailed multi-line diagrams so you don’t have to wire things twice. This helps prevent errors as well as
THE PERFECT OIL CHANGE The “Perfect Oil Change” is the easiest thing in the world to do. The problem is that oil changes are often seen as a chore, and the necessary time and attention are often skimped in the rush to get to something that seems more important. You may well be the first owner of the tractor to do this right. The first step is to get the motor good and hot. Run it for at least a half-hour, until the cylinder head is too hot to touch and the oil filter can is uncomfortably warm. This ensures that the oil is hot, which makes it flow easier, and it also makes sure that any crud in the oil is fully entrained and will come out with it. Park it, shut it off, and immediately remove the drain plug on the underside of the engine. Have a drain pan that will hold 6 quarts of oil under the drain. You’ll get a hot, oily hand, because the drain hole is big and most of the oil will come out in one big rush. Once that is draining, turn to the oil filter can, on the left side of the engine. Remove the cap by undoing the big hexagon bolt on the top. Don’t remove the filter yet. Next, locate the drain plug for the filter can – it’s on the bottom of the can, towards the front. It may have a hexagon head, or it may have a square head – either way, it’s usually all boogered up from people using pliers to remove it. Remove it, with a drain pan under the hole – this will allow the oil in the filter can to drain out. Now – go away and leave it alone. Find something else to do, but leave it to drain for at least an hour,...

Let's consider the following example: One has measured the force necessary to extend a spring from its rest (equilibrium position) for various extensions. The goal is to find the spring constant. The theory (Hook's Law) predicts the linear dependence between the force and the change of the length of the spring: F = -kx To find the spring constant k, one needs to plot the negative force -F as a function of x and find the straight-line fit. The slope of that line is equal to the spring constant k. Finding the best straight-line fit could be quite time consuming if done with a calculator. Using Microsoft Excel program significantly simplifies the whole procedure. Follow the steps shown below to make a graph and then draw a straight line that fits your data. A. Start Microsoft Excel 2010 (or Excel 2007). B. Enter your data into Excel spreadsheet. C. Highlight all cells containing data. In our example, the first column (A) contains values of x, whereas the second column (B) contains values of force -F: D. From the "Insert" tab select "Charts - Scatter". Use the first type of scatter charts – “Scatter with only Markers”. You should see a simple plot prepared by Excel. E. Next step is to add axis labels and legend to the graph. Select “Layout” tab from “Chart Tools”. Then add a header using the “Chart Title” button and add axis labels using “Axis Titles” button (both for horizontal and for vertical axes). Optionally, you may edit or simply remove the legend. Grab and drag a corner of the graph (chart) to enlarge its size. F. The last step is to add the linear fit (a straight line fit) to your graph (chart). Click once anywhere inside the graph area. Select the “Layout” tab from “Chart Tools”. Click on the “Trendline” icon and select the “Linear Trendline” option. You should see a graph similar to this: ...
