tor effective cancellation.
Measuring Two-Piece Propeller Shaft System
Working Angles
Introduction
Two-piece propeller shaft systems have three working
angles instead of two as in one-piece systems.
• The first angle is the front working angle. It
is formed by the angle of the output shaft of the
transmission and the angle of the front
propeller shaft.
• The second angle is the middle working angle. It
is formed by the angle of the front propeller
shaft and the angle of the rear propeller shaft.
• The third angle is the rear working angle.
It is formed by the angle of the rear propeller shaft
and the angle of the pinion yoke of the rear axle.
