kingpin bushing orientation
I know I asked this before but I thought I would ask again. Does anyone know which way the kingpin bushings go in? The bushings I got in my NOS rebuild kit have triangular cutouts for the grease zerk path. This is right in the middle, not offset. The grease channels cut into the bushings are not symmetrical. The shop manual says to be sure to put the bushings in with the grease channels in the correct position but does not say what that is. Thanks, that's really helpful! I know it probably doesn't make much difference but if the engineers went to the trouble to have them manufactured that way, then there must be a reason for it. I failed to make a note of how the old bushings were oriented so we just guessed. I think we pressed them in with the triangular, arrow-shaped cutout pointing in the same direction the bushing was going in. It just bugs me that I don't know for sure which way is the correct way.
Thanks!
Thanks!

2speed,
Are '52 bushings different? Mine have the opening pretty much dead center.
Jeff,
That makes sense and for once luck was on my side and I had installed them that way. George (Earl's owner) said the same thing.
It probably won't make a lot of difference but I wanted them installed correctly. I believe that engineers know what they are doing most of the time. If a part is designed to be positioned a certain way, I don't mind trying to figure out what that is. It was particularly frustrating that the shop manual made a point of saying to install the bushings with the grease channels in the correct position yet made no mention of how to determine that.

Oh yeah, make sure the hole lines up with the grease zerk. If the bushings need reamed a typical reamer can make the diameter the correct size but misalign the bore of each bushing. Find a shop that has a reamer that locates one bore off the other. But in a pinch I've used sand paper on a drill bit. The method used affects longevity more than anything.
