When fitting the SA68740S, confirm the driveshaft tube OD is 120 mm with a 3 mm wall thickness. The 114.25 mm butt diameter pilots into the tube bore; verify the tube cut is square and the bore is within tolerance before welding. The 255 mm CL-to-weld must be included when calculating overall driveshaft length for the specific vehicle application.

The SA68740S is built around the 68740/2040 series specification, which is a metric heavy-duty series used on commercial trucks and buses in markets where metric driveshaft standards are prevalent. Confirm the mating yoke and U-joint are also 68740/2040 series to maintain dimensional compatibility throughout the driveshaft assembly. Verify tube OD and wall spec before welding.
