Conversions & Hybrids - Setting pinion angle.

Alright, so I'm about to fab up my transmission crossmember, but i'm concerned with pinon angle. not sure on where the motor/trans needs be set at(angle). Will I need the drive shaft in in order to figure this out?


You guys get what I'm saying?
Anyway the help is much appreicated.

I used a level with a lazer beam. I set the differential to aim just below the tailshaft and set the transmission to aim just above the yoke. There might be a better way but this works for me.

Driveshaft not required. You want complimentary angles. For example, if your tailshaft is 3° down, you want the pinion 3° up. That's ASSuming the pinion won't rotate on acceleration or deceleration.

You want the two shafts to be parallel. In other words draw a straight line out from each shaft and adjust the mount so the lines are always the same distance apart no matter where you measure them.

i made a couple of laser pointers like in the link below. Mount them to each shaft. I then held a piece of lined notebook paper up to the trans laser pointer and marked how far apart the two dots are both up and down and left and right. I then held the paper in front of the laser pointer at the diff and did the same. Then it was just a matter of adjusting the diff and/or trans until the distances were the same front and back.

sound easy enough.
I'll have to try it out.

i always set mine up with the pinion -2 so i measure at the face of the crank pulley/ dampener and the face of the pinion gear and set it so the pinion gear is 2 degrees less.
engine l \ rear or engine / l rear hope this helps.

Great explanation on things here....

Here is another link with great info on proper pinion angle setting from Inland Empire Driveland. http://www.iedls.com/ptsetup.html

There are a lot of variables that play into pinion/driveline angles...You may want to read til your eyes bleed before you take some of this advice into consideration...Although everyone meant well...
