[TR] Steering box rebuild om 3A

[DLylis at aol.com]

There are two areas of adjustment you pay attention to.  One is the  
adjustment of the pressure on the top of the rocker shaft which is done by the  screw 
on top of the cover with jam nut.  That is a matter of gentle  adjustment.  
The other is the end float in the worm inside the box and that  is a matter of 
removing the box, maybe replacing bearings and races and shimming  the cover to 
get '0' end float.  This is a shipwrights issue because  while you are doing 
this, I highly recommend replacing the silentblocs with the  Delrin bushes in 
the steering gear AND be sure to check out the idler as to  play.  
If your problem is leaking and it is coming from the bottom of the rocker  
shaft you have a seal to replace.  If it is leaking from the "nut and  olive" 
(lets not start that again) that is a different issue.
Be warned that once you get in there you may find a worn rocker shaft and  
chipped worm and that is about $400 in new parts, as I recall.  Randall is  far 
better versed in this exercise, but this is what I found when I did  mine.
BTW it is not as precise as rack and pinion but it steers unbelievably well  
now.
