904657-12 – Short Couple Driveshaft – 1710 (1.938 x 6.094) Series – 13.380″ Flange To Flange

904657-12 1710 Series Short Couple Driveshaft 13.380" Flange to Flange

The 904657-12 is a 1710 series short couple driveshaft measuring 13.380" flange-to-flange and 7.380" centerline-to-centerline. The 1710 series uses 1.938" cap diameter trunnions with a 6.094" span, placing it at the top of the standard SAE driveshaft series torque range — above 1610 and 1480.

Specifications

• Part Number: 904657-12
• Series: 1710 (1.938" x 6.094")
• Flange to Flange: 13.380"
• CL to CL: 7.380"

When fitting the 904657-12, confirm the flange-to-flange installed dimension is 13.380" and that both end flanges are drilled for 1710 series U-joints. The 4.000" difference between flange-to-flange and CL-to-CL is consistent with standard 1710 flange yoke geometry — use this delta to cross-check your measurement method.

The 1710 series (1.938" x 6.094") requires matching 1710-series U-joints at both ends. Do not substitute 1610 or 1480 series U-joints as the cap diameter and span are dimensionally incompatible. Verify both flange yoke bores accept a 1710 cap before ordering the 904657-12.
