I tore down two spare steering boxes to gain experience in the process before taking the one in my car out and tackling it. One of the boxes appears to have been rebuilt at some point. The worm gear looks in excellent shape and has the standard type caged bearing for the front. The bottom bearing was replaced with a tapered roller bearing(skf 10302 J2). This bearing is 1/2" long so a 1/8" thick aluminum plate,the same size as the cover plate,was fabricated to go between the cover plate and the box instead of shims! Actually there was one very thin bronze shim.
Also seeing as how the bearing was not a precise fit in the box opening a very thin shim was fitted around the outside of the bearing shell and then segments of this shim were folded over to keep it in place. The person who did this had to use his ingenuity seeing as how he did not have access to a new original bearing and kudos to him.
The rocker shaft looks in good shape as well as the peg so I should be able to reuse those.
The bushing appears newish and unscored so I might just leave that as well. If I clean up the rocker shaft and bushing and fit them together there should be no side to side movement ,correct? One other thing...the bushing seems to have been pressed in about 1/8' farther than it should have been. You can see the protrusion when looking into the hole between the worm and the rocker shaft. Is that an issue?
The bushing itself does not have that spiral oil passage on it that I believe the original has. Is this a concern?
CJD...I read your last thread on parts to buy for the rebuild. When you say "upper worm shaft seal" do you mean a bronze shim?
Any advice or comments most appreciated.:eagerness:
