Depending on the seal type these two angles are varied to create a pressure distribution at the seal contact line which has a steeper slope on the oil side of the seal. The shallower the slope on the oil side of the seal, the wetter the seal will run. The spring is positioned such that axially the centerline of the spring is biased to the air ...
Labyrinth seals are also found on pistons, which use them to store oil and seal against high pressure during compression and power strokes, as well as on non-rotating shafts. In these applications, it is the long and difficult path and the formation of controlled fluid vortices plus some limited contact-sealing action that creates the seal.
A 2WD 5 speed transmission found in most light duty Toyota Dyna trucks, this transmission has a drum brake on the rear and steel housings. These transmissions can be used to give a significantly lower first, and a slightly higher overdrive (5th: 0.695:1) when fitted to an R151 4WD gearbox. [4] First Gear: 5.147:1; Second Gear: 2.74:1; Third ...
