Re: Checking Driveling Vibration & Calculating It.
Looking at these Numbers - allows - No Pinion Wrap Up . .
1. Eng. Trans . 3 Degrees Down ( Correction ) 3.3 Degrees Down ! 2. 1st Drive Shaft Driven - Trig. Out the Angle to be 4.854 Degrees . 3. 2 sec. Drive Shaft Driven Trig. Angle to be 3.75 4. Rear Diff. Total = 3 Degrees Down. Equals Operating Angles of : Operating Angles of : 1st 1.55 2nd 1.1 3rd .75 Then Also : *Taking into Acct. say 1 Degree ( Wrap Up ) for 1 ton Springs* Looks like a Need to move Pinion at Least 1.0 Degree Down in Front . . Or Add 1 Degree Shim to the ( Leaf Spring Perch ) - making Total Pinion = 2.0 Degrees Down But the Operating Angle of 1.75 Degrees . . Running down Road - I'd get . . 1st Operating 1.55 2nd Operating 1.10 3rd. Angle 1.25 Degree - which would allow approx .65 Degree Wrap Up .. Operating Angle of 1.75 Degrees Hope I have this Sorted Out Now - Anyone Say ? Corrected Type -O Last edited by Port&PolishMan; 05-14-2017 at 12:19 AM. |
