The SW1 was the second generation of 3,402 cu in (55.75 L) switcher from EMD, succeeding the SC (cast frame) and SW (welded frame). The most significant change from those earlier models was the use of an engine of EMD's own design, the then-new 567 engine, here in 600 hp (450 kW) V6 form. 661 locomotives of this design were built, [ 1 ] with a ...
The 2.2l S10/Sonoma had the starter located in the same position as front wheel drive cars. A rear wheel drive bellhousing is displayed at right, and the integrated front wheel drive bellhousing is displayed at the lower right (in this case, as a part of the GM 6T70 Transmission). GM 60-Degree 2.8/3.1/3.4/3.5/3.9 L V6 (also used by AMC) Buick ...
Below is a comprehensive drill and tap size chart for all drills and taps: Inch, imperial, and metric, up to 36.5 millimetres (1.44 in) in diameter. In manufactured parts, holes with female screw threads are often needed; they accept male screws to facilitate the building and fastening of a finished assembly.

ASTM A325 is an ASTM International standard for heavy hex structural bolts, titled Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength. It defines mechanical properties for bolts that range from 1 ⁄ 2 to 1 + 1 ⁄ 2 inches (13 to 38 mm) in diameter. [1]
From 1 ⁄ 4 in up to 1 + 1 ⁄ 2 in, thread pitch is the same in both systems except that the thread pitch for the 1 ⁄ 2 in bolt is 12 threads per inch (tpi) in BSW versus 13 tpi in the UNC. Thread form
A full turn of the thimble 12 rotates the nut sleeve 13 and its two threads (20 tpi outside and 25 tpi inside) to move the rod 1 / 20 - 1 / 25 = 0.01 in (0.25 mm) relative to the barrel. Differential screw illustration from an 1817 machine design handbook. ab & ef have one thread pitch while cd has a different one.
For example, a bolt circle of 5×130 or 5-130 indicates that a rim is to be attached to the car via 5 screws evenly spaced along a circle with a diameter of 130 millimeters. [1] Other common uses for bolt circles are for indicating mounting for sim racing and real-world car steering wheels, or in the industry for mounting of servomotors or for ...
