Offset Link Pin Bushing Orientation
Posted: November 10th, 2007, 5:49 pm
Good Afternoon,
I have a question about the orientation of offset link pin bushings. Basically, what is the proper orientation?
The Story:
I recently acquired the 1965 Autodynamics that was listed on here a couple months ago, and noticed the front end had a lot of binding, and the camber was very uneven between the two front wheels. When i disassembled it, the first thing I noticed was that the number and placement of the shims was funky.
"Passenger" Side
Lower Pin - 8 inside, 1 outside
Upper pin - 1 inside, 8 outside
"Driver" Side
Lower Pin - 6 inside, 3 outside
Upper Pin - 1 inside, 14 outside
The "passenger side" camber wasn't too bad, about 1.2 degrees camber with driver weight. The "driver side" camber was at just a tick over 1.5 degrees postive, and that side was pretty bound up.
Obviously this will get corrected when it gets reassembled, and I had considered having the offset link pin bushings installed.
However, while cleaning and prepping the beam to receive a height adjuster, I've noticed it does in fact have the offset link pin bushings. Well, I assume they are the offset bushing because if very obvious that the through-hole is drilled at a slight angle/offset.
But the big boo-boo seems to be that the offset bushings are not installed in the same orientation side to side. In an attempt to describe it:
"Passenger side" looking at the hub as mounted on car:
Thicker portion of the offset is at the top of the bushing, with the thinner portion on the bottom.
"Driver side" looking at the hun as mounted on car:
Thinner portion of the offset is at the top of the bushing, with the thicker portion on the bottom.
There are also small punch marks on the face of the bushings. Two little punch marks on the bottom bushings, and one little punch mark on the top bushings. However, the passenger side has the punch marks on the thicker section, while the driver side have them on the thinner side.
If need be, I'll try to snap a picture and host it.
Basically, are the "driver side" bushings installed 180-degrees out of orientation?
Lastly, With these offset bushings installed correctly, what would be a good starting point for washer count and placement.
Thanks for any help.
