Drive Shaft And Universal Joints - Olympic Hydro Drive Manual

DRIVE SHAFT and UNIVERSAL JOINTS

The drive input shaft is provided with a Spicer*
rectangular type companion flange (Part No. 3-1-
604). This flange is securely mounted to the drive
input shaft on a Standard S.A.E 1 ¼ inch taper.
This flange matches the 1410 Series Spicer
universal joint assembly. The drive line must be
provided with a slip joint which is to be located at
the engine end of the shaft assembly. It is
recommended that the engine be installed so that
the operating angles of the universal joints are not
greater than 8° nor less than 2°. The standard drive
tube size is 3 inches outside diameter x 0.083 wall.
The maximum length of the drive line that can be
used for the recommended RPM and horsepower
measured between journal pivots is 65 inches, and
the minimum length is 12 3/8 inches.
Contact your local universal joint specialist for
recommendations on your installation and for
proper selection of the 1410 Series universal joints,
drive tube, and slip joint to adapt to your engine.
Your universal joint specialist or automotive
machine shop is equipped to assemble, weld, and
dynamically balance the drive line.
In using universal joints, the best results are
obtained with the joints operating at equal angles
and with the shafts parallel. The angle of both joints
must lie in the same plane. When assembling the
drive shaft, the slip joint must be installed so that
forks 1 and 2 lie in the same plane. (Figure 3.)
