The internal width of the overbridges was only, but the railway's springs on No . 2 were adjusted and the crank pins shortened to reduce its oscillation.
22.
On the reboilered 7th Class locomotive, problems were experienced with overloaded bearings and loose crank pins which led to a decision not to convert any of the others.
23.
The term " scotch yoke " continues to be used when the slot in the yoke is shorter than the diameter of the circle made by the crank pin.
24.
The crank pins are not normally called " journals " although they form the centre shafts of the big end bearings and are therefore journals in the more general sense.
25.
Note that typical 2-stroke V4s have four crank throws or pins ( see below ) so it is important to stipulate all four crank pin phases with the two-stroke engines.
26.
Since the cylinders center-lines were no longer centralized over the crank pin bearing journals, the connecting rods were re-designed with the big-ends offset from the piston pin ends by 1.5 mm.
27.
As this engine was not a true V6 but had a separate crank pin for every connecting rod, the crank pins were offset by 55 degrees within every pair of cylinders.
28.
As this engine was not a true V6 but had a separate crank pin for every connecting rod, the crank pins were offset by 55 degrees within every pair of cylinders.
29.
Lancia Fulvia V4 engines with narrow V angle have crank pin phase offset corresponding to the V angle, so the firing spacing ( phase pattern ) is exactly like an ordinary inline-four.
30.
In the V6 with 120?between banks, pairs of connecting rods can share a single crank pin, but the two cylinder banks run like two inline 3, both having an end-to-end rocking couple.
