Re: Measuring for torque tube shortening
.
Similar to what Mart is saying above, the PIN hole location in the pinion spline for rear end of the drive shaft is one of the critical measuring points.
The centerline location of the speedometer gear is the other critical measuring point on the front end of shaft. ALWAYS cut torque tube at REAR end. The length required of the torque tube will be determined as a result of situating the rear end banjo housing at the desired location, fore/aft. Bolt the bell end of the torque tube to the transmission. Whatever dimension of tube that goes rearward BEYOND the banjo front bolt face is the total amount to shorten torque tube...shortening at REAR of tube.
When re-welding rear of torque tube, make sure the drain-back hole in banjo flange is at the correct, BOTTOM rotation. Also, make sure SPEEDOMETER turtle hole is clocked as necessary for your application. DD
