Spohn Adj. People inside
Spohn Adj. People inside I just installed a new Moser 12-bolt along w/ a Spohn Adj. TA and the rear pinion angle is off by alot. the drive shaft is at like a -1 and the rear is going upwards at about a +2 so it has a +1 angle which is not where i want to be. I bought the set up used so i dont have any instructions on how to adjust the Pinion Angle w/ the TA so if anyone can shed some light on this it would be appreciated.

Mine was way off as well. Loosen both of the lock nuts and adjust it to where you want it. Don't go by the drive shaft angle. Check it at the tailshaft of the tranny and the yoke of the rear end. If the tranny tail shaft is at 0 degrees then set the rear yoke angle at -2.

I usually measure the angle of the oil pan on the engine since I believe its parallel to the crank/transmission centerlines.
There is also a catch to setting pinion angle too.If your tranny centerline is say -4 degree's,the rear needs to be set at +2 to +4 degree's.This will 0 out the rotating mass.You'll know when it's not right by serious vibration and high speeds.
Tonigth i removed the driveshaft and stuck the angle finder on the trans output shaft. it was -4* and the Rear is like i said before is at +2*. which turns out to be -2* over all but i though the rear was supposed to be the (-) number and the engine center line the (+) number. this way the rear has a +2* and is pointing upwards. i always though the rear needed to be angled down for better traction or is it just the overall angle that were after? I read the above post and i just wanted to clarify that i should be ok since this is all new to me. Another question i have is if this need to be fixed can i shim the trans up under the trans mount to 'zero' it out?
with the weather being pretty bad around here i cant get the car out of the garage to go test it. i'll take it out the first nice day i get and take it up to speed and see if there is any noticable vibration. sorry for the long post.
Fireball: i checked the oil pan and it was -3* so mine is off by 1* from the trans output shaft center line.

The easiest way to explain it is that you first have to zero out the rotating assembly.So if the tranny is -4,then the rear has to be +4.Then if your shooting for -2 degree's of pinion angle,you take it off the +4 which ='s +2..The rear will be pointing up,but that is correct for your app.
Mine is the same as yours but I set it for 0 pinion angle(+4) which got rid of all of my vibration.
