Thread: Pinion Angle

Tweet

I've been trying to copy photos from my gallery (page 5, photos 624 and 626) to this thread in order to show explain how I deal with drive line angles. In these particlarpics, however, it is a irs altho what I want to do does do some basic install strategy and process.











In the photo at the left you can see the fixture that I use on cars similar to the 30s hot rodsto locate the crank nose centerline at the level of the top edge of the frame rails(this is for blocks/cranks similar to chev or non FE type fords or 383-hemi mopars with skirted blocks) Center pic shows crossmember with transmission mount bolt holes to locate trans tailshaft c/l in direct line toward pinion shaft c/l (yes, I do the fabrication around a direct line for crank/trans/pinion and then work offset for some u-joint angle)Pic at right shows me moughting up the brake system master and hydraboost. I will mount up all the stuff for the vehicle BEFORE I do all the tubes for the center frame structure---fuel pumps/filters/regulators/exhaust(this car got side pipes,easy)


This car got an Ford 9 inch IRS with a centered housing resulting with a sideways angle to the drive shaft amount of the pinion offset in the Ford niner (forgot exactly what the degrees result was with this length shaft but within reason)


With the IRS there is no movement of the housing so it was a piece of cake compared to a live axle type build.
