GRINDING MACHINES Grinding is the process of removing metal by the application of abrasives which are bonded to form a rotating wheel. When the moving abrasive particles contact the workpiece, they act as tiny cutting tools, each particle cutting a tiny chip from the workpiece. It is a common error to believe that grinding abrasive wheels remove material by a rubbing action; actually, the process is as much a cutting action as drilling, milling, and lathe turning. The grinding machine is used for roughing and finishing flat, cylindrical, and conical surfaces; finishing internal cylinders or bores; forming and sharpening cutting tools; snagging or removing rough projections from castings and stampings; and cleaning, polishing, and buffing surfaces. Once strictly a finishing machine, modem production grinding machines are used for complete roughing and finishing of certain classes of work. The grinding machine supports and rotates the grinding abrasive wheel and often supports and positions the workpiece in proper relation to the wheel. Grinding machines have some special safety precautions that must be observed. These are in addition to those safety precautions described in Chapter 1. SAFETY PRECAUTIONS GRINDING MACHINE SAFETY Grinding machines are used daily in a machine shop. To avoid injuries follow the safety precautions listed below. Wear goggles for all grinding machine operations. Check grinding wheels for cracks (Ring Test Figure 5-11) before mounting. Never operate grinding wheels at speeds in excess of the recommended speed. Never adjust the workpiece or work mounting devices when the machine is operating Do not exceed recommended depth of cut for the grinding wheel or machine. Remove workpiece from grinding wheel before turning machine off. Use proper wheel guards on all grinding machines. On bench grinders, adjust tool rest 1/16 to 1/8 inch from the wheel. 5-1 TC 9-524 TYPES OF GRINDING MACHINES From the simplest grinding machine to the most complex, grinding machines can be classified as utility grinding machines, cylindrical grinding machines. and surface grinding machines. The average machinist will be concerned mostly with floor-mounted and bench-mounted utility grinding machines, bufting machines. and reciprocating surface grinding machines. UTILITY GRINDING MACHINES The utility grinding machine is intended for offhand grinding where the workpiece is supported in the hand and brought to bear against the rotating grinding abrasive wheel. The accuracy of this type of grinding machine depends on the operator’s dexterity. skill, and knowledge of the machine’s capabilities and the nature of the work. The utility grinding machine consists of a horizontally mounted motor with a grinding abrasive wheel attached to each end of the motor shaft. The electric-motor-driven machine is simple and common. It may be bench-mounted or floor-mounted. Generally, the condition and design of the shaft bearings as well as the motor rating determine the wheel size capacity of the machine. Suitable wheel guards and tool rests are provided for safety and ease of operation. Grinding machines come in various sizes and shapes as listed below. Floor Mounted Utility Grinding Machine The typical floor-mounted utility grinding machine stands waist-high and is secured to the floor by bolts. The floormounted utility grinding machine shown in Figure 5-1 mounts two 12-inch-diameter by 2-inch-wide grinding abrasive wheels. The two wheel arrangement permits installing a coarse grain wheel for roughing purposes on one end of the shaft and a fine grain wheel for finishing purposes on the other end this saves the time that would be otherwise consumed in changing wheels. Each grinding abrasive wheel is covered by a wheel guard to increase the safety of the machine. Transparent eyeshields. spark arresters. and adjustable tool rests are provided for each grinding wheel. A tool tray and a water pan are mounted on the side of the base or pedestal. The water pan is used for quenching carbon steel cutting took as they are being ground. Using the 12-inch wheel, the machine provides a maximum cutting speed of approximately 5.500 SFPM. The 2-HP electric motor driving this machine has a maximum speed of 1.750 RPM. 5-2

Pg. 62-63 Drivers' Racing Shoes - Victory Lane Magazine

Personal Safety equipment is part of the driver mental and physical racing package. Two months ago in Victory Lane Magazine, we discussed drivers suits as the first in a series on personal safety equipment. This month we will discuss racing shoes. This continues the topic of safety and begins a series on the selection and use of racing shoes. As with previous topics, the racer needs to check with his/her local racing club and make sure t h a t Pyrotect racing shoes. the shoe type is approved and/or fits with the club’s guidelines for racing shoes. One of the primary functions of a racing shoe or racing boot is to allow the driver to “feel” the pedals of the car, this tactile interaction of the driver and the car’s controls is of the utmost importance. Another key feature of the product is to provide a shoe sole that feature low, or no heel elevation, as this disrupts the ease of pedal movement. There should be no overhanging sole edge to be trapped behind pedal edges. The laces should help the shoe fit securely. Some shoes have Velcro that keeps the foot secure and prevents movement. The lace ends should be worn under the racing suit bottom or be covered by the Velcro strap. It is a must that if you are driving a race car on track, the shoes should be fire resistant with Nomex lining. The size and shape of the shoe needs to conform to the pedal space of the individual vehicle or car. Many racing clubs require that shoes and or boots conform to the SFI Standard 3.5, which says that “shoes and boots shall incorporate fire resistant/retardant material in the non-sole area. Other materials may be used providing they do not inhibit the protective capability of the assembly. Shoes shall have a standard configuration. Boots shall extend up the leg at least six (6) inches (15.2cm). This dimension shall be taken at the rear of the boot, measured from the bottom of the sole to the top of the extension.” We are interviewing makers and suppliers of racing shoes and will have a series of articles about these interviews. In this issue there are interviews from maker Oakley Race Wear and suppliers Averill Racing Stuff and Safe Racer or ...

The subject vehicles are equipped with brake pressure accumulators consisting of a metal plunger containing brake fluid encased in a metal housing. The plunger is designed with metal pleated bellows to allow for motion. Nitrogen gas is sealed between the plunger and housing. There is a possibility that a fatigue crack could develop in the bellows due to the vertical vibration of the plunger while driving. If this occurs, nitrogen gas could leak into the brake fluid and gradually cause the brake pedal stroke to become longer, resulting in decreased hydraulic pressure. Under certain circumstances, this condition could affect stopping distance and increase the risk of a crash. Q1a: A1a: Q1b: A1b: Q2: A2: What is the Brake Pressure Accumulator? Brake fluid is discharged by the Brake Booster Pump and passes through a check valve where it is then stored in the accumulator. The brake fluid that is stored in the accumulator provides the hydraulic pressure that is needed for brake operation. What is the cause of the condition? The cause of this condition is insufficient strength of components inside the brake pressure accumulator. Are there any warnings that this condition exists? Yes. You may notice a squeak from the engine compartment during brake application. Additionally, the brake pedal may have a longer stroke and/or spongy feeling.

JEGS 80079 Engine Stand Installation Instructions

Ford EFI Engine Lift Plate Safety Guidelines The installation begins with common sense! It is highly recommended that you support the vehicle with four heavy duty jack stands. ALWAYS use an engine hoist specifically designed for this procedure. The vehicle should be positioned on a hard, flat and level surface (asphalt in the summer can be very dangerous). NEVER use a bumper or scissor jack for the support of your vehicle! ALWAYS use safety glasses. Allow the engine and transmission to cool before disassembly. Instructions 1. If you are unfamiliar with the vehicle wiring, fuel connections, coolant or vacuum hose routing, it is always advisable to mark each connection before removal. 2. Always make sure the engine is cold and relieve fuel pressure to minimize the possibility of personal injury or vehicle damage. Use caution in removing electrical connections due to the sensitive nature of most locking style connectors. 3. Remove the coolant hoses, fuel lines, inlet ducting, throttle cable/linkage, vacuum hoses and wiring from the alternator, battery, distributor, gauge sending units, injectors, starter and throttle body. 4. Remove the 6 or 8 (varies by intake design) upper to lower intake manifold bolts. 5. Carefully remove the upper intake from the lower. In some cases the upper may be heavy and may require some maneuvering. 6. With the alignment tab facing the front of the engine, attach the lift plate using the hardware included and tighten the bolts to 12-18 lb ft. 7. Attach the engine hoist lift using one of three holes in the plate to achieve the proper lifting point and tilt angle to the engine assembly for removal making sure that all hooks, bolts, pins etc. are secure before placing tension on the chain assembly. 8. Remove the driveshaft and insert a plug or extra yoke on the output shaft of the transmission to prevent fluid leakage. Secure to prevent the unit from becoming disengaged during the removal process. 9. Remove the remainder of the bolts from the exhaust, motor mounts, driveshaft and transmission crossmember. 10. Always utilize a helper when attempting engine removal for your own personal safety and ease of removal. 1-800-345-4545
