Installation of Split Shaft
Installation Instructions – Split Shaft
Split shaft Power Take-Offs are installed into the vehicle driveline. This requires cutting and reworking driveshafts.
No attempt will be made here to list driveline fabrication or rework procedures. For answers to specific questions,
contact the Drivetrain Service Division. Listed are the necessities for a good Power Take-Off installation that will
run quietly and without vibration. The unit itself should be suspended from a rubber isolated crossmember and will
replace the center bearing for the driveline. Grade 8-Bolts should be used for all fastenings.
1. Front—a short coupled joint connecting the transmission to the split shaft should be installed so as to permit
equal joint angles of less than 3°.
Rear—A two joint assembly connecting the split shaft to the rear axle should be installed so as to permit
equal joint angles of less than 5° to ensure the best performance. The joint angles should be kept within a
minimum of 1° to 3°.
Front & Rear—the two joint assembly at the front and rear should be installed so as to permit equal joint
angles of less than 5°.
2. Determine a suitable location for crossmembers for mounting the split shaft. Raise or lower or move the split
shaft front or rear as required to reduce the joint angles to a minimum but not less than 1°.
3. Align the split shaft with the transmission and rear axle.
A. For the best installation and optimum performance, the input and output shafts of the split shaft should be
parallel respectively within 1° to the main shaft of the transmission and the pinion shaft of the axle.
B. With the shafts parallel, the joint angles should be in one plane only. Make sure the offset in the horizontal
or vertical planes will provide for equal joint angles of less than 3° with a short coupled joint or less than 5°
with a two joint assembly.
4. Excessive angles result in a loss of speed and power. The figures shown below are approximate and any
angle less than those shown will provide a better installation.
Speed
5,000 RPM
4,000 RPM
3,000 RPM
Slight angles of 1° in each joint are necessary for the circulation of the needles.
5. The front and rear shafts should be assembled, straightened, and balanced before installation.
