pitman shaft(output) seal on a '90 F150 2wd power steering box


does the seal have a metal lip shell around it that overlaps over the under edge of the steerin box housing around the pitman shaft opening?

or do you not mess with the metal shell?
(when replacing the seal)

from the pics of the new seals i cant see a metal shell lip part of the new seal.

so im confused..

ive got the pitman arm rmeoved and the snap ring removed and im confused what part is the actual seal and what is not

completely rubber?

or metal shell also?

google has been no help at all

i dont know these ford p/s boxes very well.


thanks

 

The sector shaft seal kit comes with the dust seal, the pressure seal and sometimes a metal washer/shim which you usually don't need.

Look at the bottom right part of the picture below.

Some people pull the pit-man arm, remove the snap ring, start the engine and turn the steering wheel left and right which blows the seal out of the gear box. If the leak at the seal is too big this method doesn't work.

I ended up pulling the steering box, removed the top cover and knocking the
seal out from the inside. I did have to readjust the sector shaft adjusting screw which is not easy to do if you don't have an analog dial type inch lb. torque wrench.
