One of the most important tools in an automotive repair shop is the auto lift. Providing access to the under belly of a car or truck, automotive lifts make the job of car repair much easier for the home garage or auto shop. Choosing a lift that meets your needs is the key to profitability in time and money. There is a large variety of lift types available to meet the needs of anyone who is looking to purchase one. Keep the following in mind when choosing the best automotive lift for you.

Auto Lifts For The Home User

Consumers with a garage at home can now easily perform maintenance and repairs on the undercarriage of their automobiles. The convenience of owning a home auto lift not only increases the productivity of repairs, but also increases the amount of storage space available. Home automotive lifts usually involve a group of four posts, pneumatically controlled to lift an automobile safely.

These lifts provide a safe means to raise one’s vehicle for access to the car’s undercarriage for transmission and oil work. Automotive lifts also provide increased storage space, by allowing the consumer to lift their car out of the way and to open up the garage floor space. Lesser used vehicles and box storage can be placed on the lift and raised out of the way. Then, you can park your own vehicle underneath the lifted platform.

Automotive lifts are great for people who collect cars. A typical garage can only house two cars, but with use of a lift, four cars can be efficiently parked.

Auto Shop Automotive Lifts - Features To Consider

For more serious garages and commercial operations, there are heavy-duty automotive lifts available. Standard equipment usually involves one, two, or four post lifts. The final choice involves the balance of lift capability, lift stability, and available additional space for the lift equipment. These heavier lifts usually require additional maintenance. The industrial nature of these auto lifts means that their maintenance is better left to professionals if the user has any doubt about being able to work the equipment while maintaining the designed safety features.

One post lifts are the most economical in terms of space. The two varieties of one post lifts are centered lifts and offset lifts. Centered one post auto lifts have a lot more strength than offset one post auto lifts. Offset lifts provide space for a vehicle to be placed underneath a lifted object, providing space economy. Four post models also allow for the same space saving capabilities as a single post model, but they do require more space and power. The upside to a four post lift is a greatly increased power output (four times that of a single post). The two post model is a balance between the two versions.

Auto lifts give a home user full access to their vehicle from different sides. This allows you to perform maintenance and repairs on your vehicle from the comfort of home, saving you both time and money.

Handling Soot in Antique Car Engines
By Peter Salmonford

In the course of running soot is formed in the engine, the quantity varying with the richness of the mixture and the facility for the lubricating oil to get past the piston. This carbonaceous deposit, combined with the non-inflammable constituents of road dust which are sucked through the carburetter, adheres to the cylinder walls and combustion head, causing falling off of power, and in time preignition. When the valve cap is removed it will be found that its underside is coated with soot, and sometimes even with a hard deposit, an indication of the state of the interior of the cylinder. To remove this carbon deposit, the usual procedure is to take off the cylinder so as to expose the parts and scratch off the deposit with a screwdriver or some similar instrument. From the tops of the piston the deposit can be cut away with a knife, and when removed the surfaces should be polished with fine emery cloth, as deposit adheres less easily to a polished surface. The deposit must be completely removed from all parts of the cylinder as well as the piston, a matter of some difficulty.

There have been one or two inventions evolved from time to time to remove the deposit without necessitating the dismantling of the engine. One of these is to insert a steel ball of about 5 inch diameter into the cylinder and then to run the engine, its action being to hammer the carbon deposit and so chip it off the surface. Another, and more promising, process consists in passing a stream of oxygen into the cylinder, lighting it, and so causing a chemical combination to take place between the carbon and the oxygen. As soon as all the carbon has combined the flame goes out, and it is known that the cylinder is clean. The writer has not tried either of these schemes, but mentions them as matters of interest. The ball process, however, would seem rather risky.

To keep an engine in good running order the valves, apart from grinding-in, require careful attention. In the olden days silence of running was not of great importance, but nowadays it is an essential, and to obtain it one of the most important points is to see that the clearance between the valve tappet and the bottom of the valve stem is small. As the engine runs it will be understood that the tappet rises rapidly and strikes the foot of the valve. If there is a large clearance between these two the impact between the tappet and the valve causes a clicking noise, which should be stopped by adjusting the tappet head close up to the valve stem. The usual distance or clearance is about 5 inches. The top of the tappet head is inlaid with fibre to reduce the noise, and in course of time this fibre becomes dented or recessed. The tappet should then be removed and its head filed flush so as to remove the indentation.
