What degree should pinion angle be?
between 1 and 3 degrees
According to Currie, the average car crafter should strive for between 1 and 3 degrees between the tailshaft of the transmission and driveshaft, and 1 to 3 degrees between the driveshaft and pinion. Furthermore, the two angles should be nearly equal (between 1 and 3 degrees), but always opposite (see crude diagram).
Does ride height affect pinion angle?
The ride height has no bearing on the engine angle, but it does on the pinion angle with a live rearend.
What does changing pinion angle do?
For tubeframe cars, pinion angle is the difference between the angle of the driveshaft versus the angle of the pinion shaft. Knowing how much our suspension linkage changes the angle of the pinion, we can lower the angle of the pinion at the yoke end by the same amount that the suspension permits the pinion to raise.
Does tire size affect pinion angle?
Tire size does not affect the angles. If you put larger diameter tires in the rear, the rake of the car changes, so does the relative angles with respect to true level.
Does tire size change pinion angle?
Tire size does not affect the angles.
What is the minimum U joint operating angle that manufacturers recommend?
1 DEGREE
RULE 1: UNIVERSAL JOINT OPERATING ANGLES AT EACH END OF A DRIVESHAFT SHOULD ALWAYS BE AT LEAST 1 DEGREE.
What is the max pinion angle?
In order to minimize power loss and vibration in an offset configuration, the pinion centerline and the transmission centerline need to be parallel. In general, the largest angle for racing applications should be 2 degrees and the centerlines should be parallel within a few 1/10 of a degree.
How important is pinion depth?
Proper pinion depth makes sure the pinion teeth mesh with the middle of the teeth on the ring-gear – between the top and the root. Increasing pinion depth moves the pinion closer to the center-line of the ring gear, moving the pinion “deeper” into ring-gear teeth and reducing the checking distance.
How can I increase my pinion depth?
Use shims to move the ring gear closer to the pinion to decrease backlash. Use shims to move the ring gear farther from the pinion gear to increase backlash. Use shims to move the pinion closer to the ring gear to move the drive the pattern deeper on the tooth (flank contact) and slightly toward the toe.
