204249-1 – Short Couple Driveshafts – 1550 (1.375 x 4.964) Series – 8.500 – 5.500

204249-1 1550 Series Short Couple Driveshaft 8.500" Flange to Flange

The 204249-1 is a 1550 series short couple driveshaft measuring 8.500" flange-to-flange and 5.500" centerline-to-centerline. This is the shortest unit in the 204249 1550-series family. The 1550 series uses 1.375" cap diameter trunnions on a 4.964" span.

Specifications

• Part Number: 204249-1
• Series: 1550 (1.375" x 4.964")
• Flange to Flange: 8.500"
• CL to CL: 5.500"

When fitting the 204249-1, measure the installed flange-to-flange gap and confirm it is 8.500" with both flanges fully seated. The 3.000" differential between F-to-F and CL-to-CL reflects the combined flange yoke CJ-to-flat geometry. Both end flanges must be bored for 1550 series U-joint caps (1.375" diameter).

The 204249-1 is the shortest unit in the series at 8.500" F-to-F, 5.500" CL-to-CL. The 204249-2 is next at 8.750" F-to-F with a 5.750" CL-to-CL. If your installed F-to-F falls between 8.500" and 8.750", measure CL-to-CL as well — the differing CL-to-CL values between the -1 and -2 units indicate different flange yoke configurations at one end.
