I;m replacing the clutch in my 94 F-250 powerstroke and want to replace the front seal on the trans as well. How do I remove the housing that the throwout bearing rides on to replace the seal? I don't want to mess up the shaft. Thanks

 

Remove the three release bearing guide tube retaining screws. Remove guide tube.

NOTE: The through-bore of oil seal is designed such that oil seal can be
removed without having to disassemble the transmission if removal and replacement of oil seal is all that is required.
Tap on oil seal with a screwdriver until oil seal turns then use the screwdriver to pry out oil seal. Insert new oil seal and drive it in flush with the case.
Driving the seal into the case itself is NOT recommended.
