2 engine building enthusiasts (me and my dad) have worked on this for the last nights to get this Idler Gear Stud (and Gear) in the correct location for gear mesh, etc. What a sucker it was . . . and now we need to make a sharp, steel, center punch deal to fit over the end of the idler shaft, and a solid aluminum plug installed in the gear cover, and "center punch" the cover, then we know where to bore the bushing perfectly - so the stud is supported in the cover too . . . It Still Ain't Done Yet !
