Cut Drive Shaft Assembly
The inner drive shaft is shipped separate from the turntable and consists of the
following:
• Drive shaft section (A)—2.37-in diameter x 82 in long, with a grooved
1.06-in diameter end for the turntable side
• Drive shaft section (B)—2.37-in diameter x 72 in long, with a knurled 1.0-in
diameter end for the motor drive side
• Shaft coupling—with 1/4–20 self-tapping screws for joining the two shaft
sections
Follow these steps to cut the shaft to the desired length. The material is PVC and
can be cut with a hand or reciprocating saw with a 6-in blade length.
1. Determine the distance DIM1 from the center of the turntable to the
mounting holes in the floor support next to the motor drive unit. This
DIM1 dimension is critical in determining the length of the drive shaft and
shaft housing. See Determine Shaft Length on page 24 for more
information.
2. Determine the required total length of the drive shaft after section A and
section B are connected with the coupling.
3. Subtract 978 mm (38.5 in) from DIM1 in step 1 for the total overall length
of the shaft.
4. Subtract 6.3 mm (0.25 in) for the total combined cut length of section A
and section B. The coupling will add 6.3 mm (0.25 in) to the shaft length
after the two sections are assembled.
5. Divide the total cut length in step 4 in half. Cut shaft B longer than
shaft A as described:
• Add three inches to the half length, and mark shaft A to this length.
Measure from the 1.0-in diameter end.
• Subtract three inches from the half length, and mark shaft B to this
length. Measure from the 1.06-in diameter end.
This will offset the coupling three inches from the center after it is
assembled.
