Installation Techniques
On applications having more than two shafts, mount the first coupling shaft as outlined in the preceding example, and each addi-
tional coupling shaft at a 1 to 1-1/2 degree universal joint operating angle to the previous coupling shaft.
Install or tilt the axle to the same angle as the last fixed coupling shaft so the centerline of the axle and the last fixed coupling shaft
are parallel.
Note: THIS ASSURES THE UNIVERSAL JOINT OPEARTING ANGLE AT EACH END OF THE LAST SHAFT WILL AUTOMATICALLY
BE EQUAL (See Fig. 11).
