Want this question answered?
You take driven divided by drive. 15 divided by 5 is 3. So the ratio would be 3:1
You would use a worm drive meshed with a gear that has 130 teeth.
Number of teeth on driven gear divided by teeth on driven gear.
What is the speed ratio of an input with 36 teeth meshed to a gear with 20 teet?
The answer does not depend on which gear is driving. Linear-wise, the two gears are meshed so the teeth are moving at the same speed. Rotation-wise, the smaller gear has smaller radius so it is "turning faster" in terms of RPMs.
The transmission input shaft has gears on it that mesh with the different drive gears. It is spun by force from the engine, as you select different gears with the shifter, there are different sets of gears being meshed together inside transmission. The synchronizers ensure that the gears being meshed together are turning at the same speed, thus resulting in a smooth shift and no damage to the gears.
First start the gear > Typically, turning a rotating drive line through 90 degrees (turning a corner).
Tech b
Third gear could have a broken tooth, chipped tooth or bent tooth on the gear and only makes a noise when it has drive pressure applied to it, so either way when pressure is applied it makes a noise.
There is a picture of a gear in the related link. a gear tooth is one of the things on the outside of the gear that sticks out. This gear has 18 teeth.
The gear is the same, but the nose cone is different.
Could be starter drive not engaging xcompletely Could be a bad starter drive Could be a chipped or broken tooth on ring gear (fly wheel) Try turning engine manually (large socket on crankshaft) and then try to start - -if vehicle does turn over probably a chipped or broken tooth - if not, possible above starter problems
