Pinion Angle Question

[chicane]

I see what... you... are saying Tim. But the disconnection with how the others try to explain it leaves a reader astray.

Although... your example above... -4*/-3*/+4*... describes a truck... not a lowered street car. This cannot be applied to the example. Beside's... (-4)+(-3)+(+4) does not equal less than 1 or close to it. -3* is still outside of the 1* maximum. I hate to think that you are looking at this from a shaft angle 'point of view'.

The reality is... it would be better for the individual chassis to be measured, loaded, at ride height and make an adjustment from there.

In Pilot20's example... and with the relative suspension articulation associated with the peticular suspension being used... the pinion centerline and the transmission centerline need to be parallel and within 0.500*. With the associated suspension movement the operating angle will increase, but should not exceed 15 degrees. If he runs -3.5* power train and +3.5* pinion... he is well within the 0.500* tolerance... at a given ride height. It will change if/when the suspension is lowered and/or raised. But if he were to set it at -3.5*/+3.5* at static ride height... I dont believe that he will obtain the 15* maximum with the suspension lowered.

Anyway... we are
