A Word to the Motor Mechanic
The repairing and servicing of the automobile, bus and truck is an important and active industry in the United States, because more than 26,000,000 motor vehicles must be repaired and maintained if they are to operate ej|fideafly in transportation.
To properly handle this work the motor machine shop must have practical precision equipment. Car and truck owners are discriminating more and more in favor of the well-equipped~ shop that turns out a first class, accurate job at a reasonable price. The well-equipped shop soon becomes the best known shop in the community. `
No single piece of equipment so well enables the shop to do a wide range of accurate service work at reasonable prices and at a good profit, as the Back-Geared, Screw Cutting Lathe. This universal tool when fitted with proper attachments, will do all the service jobs which would otherwise require several single purpose machines. For ~example, one South Bend Lathe, with a few attachments, will handle the grinding of valves, boring of connecting rods, making of bushings, truing of armatures, undercut- ting of mica, finishing of pistons by turning or grinding, machining of flywheels for ring gears, cutting of screw threads, general machine work, etc.
The price of a lathe and attachments for handling gen- eral automotive service work in the motor machine shop is less than one-fourth the total price of the special machines required to do the same work. No other shop tool .is the equal of the lathe in versatility, ease of opera- tion, wide range, accuracy and economy of operation. In this handbook are illustrated and described a few of the most important motor service jobs, and the latest shop practice for handling them. South Bend Lathe Works
< The Back-Geared, Screw. Cutting Lathe is an all-round general purpose tool-the most practical tool in the equipment of the motor machine shop. The lathe is popular because it ~can take care of all jobs specified in the following list and hundreds of other jobs.

Fig. 2. Machining a Flywheel for a Steel Starter Gear in the 16" x 8' South Bend Lathe
Machining Flywheels
For machining flywheels for steel starter gears,truing the clutch face, and handling other fly-
wheel servicing operations, we recommend the16" x 8' South Bend Lathe as listed in the
No. 16 Shop Equipment on page 14. The South Bend method of mounting flywheels, as shown
in Fig. 3, is efficient and accurate and insures that the machined surface of the flywheel will
run true with the axis of the crankshaft. Fly-wheel servicing can also be done on the 18-inch
and #36-inch lathes.
for Steel Starter Gears
Tf e time required to machine a flywheel in the lathe and fit it with a new steel starter gear
is from 20 to 30 minutes. For prices of fly- wheel servicing equipment, see page 27.
In addition to servicing flywheels, the 16-inch lathe is practical for truing brake drums of de-
mountable wheels, servicing crankshafts, driveshafts and axles, pistons, connecting rods, dif -
differentials, valves, bushings, armaratures , cut tin gib screw threads, for general machine and repair
work, and hundreds of other jobs.
"How to Service Flywheels"-Bulletin No. 3
Th e motor mechanics interested in handling flywheel work should have a copy of this 8-page bulletin, size 81[2xl I inches, for
reference becauseit shows the most practical and efficient method for doing this import-ant work. The bulletin contains more than
thirty illustrations show-ing how to mount a flywheel in the lathe for removing damaged teeth;
machining the flange for starter ring gear, and many other jobs.
