904657-1 – Short Couple Driveshaft – 1710 (1.938 x 6.094) Series – 10.620″ Flange To Flange

904657-1 1710 Series Short Couple Driveshaft 10.620" Flange to Flange

The 904657-1 is a 1710 series short couple driveshaft with a 10.620" flange-to-flange length and 6.620" centerline-to-centerline dimension. This is the shortest unit in the 904657 1710-series family available with both F-to-F and CL-to-CL data, suited for tight-clearance installations requiring maximum torque capacity at a compact assembled length.

Specifications

• Part Number: 904657-1
• Series: 1710 (1.938" x 6.094")
• Flange to Flange: 10.620"
• CL to CL: 6.620"

When fitting the 904657-1, verify the installed flange-to-flange measurement is 10.620" with both companion flanges seated. The 4.000" F-to-F to CL-to-CL differential is consistent with standard 1710 flange yoke CJ-to-flat geometry. Both end flanges must be bored for 1710 series U-joint caps (1.938" diameter).

Within the 904657 series, the -1 suffix denotes the shortest available F-to-F at 10.620". If your application measures closer to 11.620" F-to-F, cross-reference the 904657-5. Both share the same 6.620" CL-to-CL, so measuring flange-to-flange is the decisive dimension for selecting between these two units.
