LONGER LIFE

Decrease Your Car Vibration The smooth action and long, useful life of the modern automobile is due m no small part to the war that has been waged against vibration by the car manufacturers. TVLTHOUGH it is impossible to ellml- ** nate this, destructive l agency entirely, its damaging effects have been greatly minimized by improvements m design and construction. Crankshafts have been made stiffer and mounted more rigidly m their bearings. As an additional step* 'the use of a greater number of bearings holding the shaft at more points has been found effective. Reciprocating parts have 'been made lighter and sets of connecting rods and pistons more carefully balanced. Combustion chambers have been made uniform m size to equalize explosion forces. % x Closer fitting of bearings and pistons has taken up the play that results m premature wear. Engines have been more securely mounted, frames made stiffer and rer inforced to withstand the twisting Ftrains set up by the forces acting on the crankshaft. Valves, camshafts, and gears have come m for their share of consideration. 1 More careful design of cams and pear teeth have made these parts function more smoothly.
