Another quick pinion angle question

Hi guys, I'm wondering if you could confirm something for me.

I have been playing arouns with pinion angles of late, and as wel all know the dual shaft setups are a bit more complicated than the singles ones, but the same principles apply.

With that in mind, I'm setting up my Toyota dual cab rear end and was wondering if wehat I have sounds right.

I have my trans pointing down 4 degrees, and the first shaft point down 1 degree. The second shaft is pointing up 3 degrees and the pinion is sitting at zero degrees.

If the same basic principles are applied than that of a single shaft setup, it should be ok, right? I figure 4-1 equals 3 degrees working angle for the trans/first shaft, and 3 degrees plus or minus zero for the second shaft/pinion. This would effectively cancel out all angles right, or am I way off?

I have lifted the carrier bearing to take the extremes out of the angles, but I want to get my angles spot on so when/if I change to larger/smaller wheels in the future, I have maximum adjustment forward and back on my link arms.

Any help/insight would be great.

Thanks,

LeighOZ.

P.S...I have read the bagginit.com article and anything else I've been able to find!

Anyone?

I PM'd this to you on ARTcom as well...

Ok, so your trans points down 4*, and the first shaft goes down 1*. You go the operating of 3* correct. Now the second shaft points up 3*, so the operating angle between the first and second shaft is 4* (3up + 1 down).

So now we take the second operating angle (4*), and subtract from itthe first (3*), to get 4* - 3* = 1*. (note: it doesn't matter which is subtracted from which, as there really are no 'negatives' and 'positives'. You'd get either a -1, or a 1, which are both 1* operating angles).

So the operating angle between the diff and second shaft would have to be 1*. But if you already have your rear end in place, and you're adjusting link bars, then the second shaft will change angle as you change the pinion angle, so essentially you'll want to adjust it a lil, then remeasure, recalculate, etc, etc, until you have it right.

Make sense?
