oil seal for automatic transmission control shaft
 

This is the third time I'm replacing this seal (91209-612-003) on my son's 2001 4 cylinder Accord, and they always seem to leak (part #10 in the diagram). Does anyone know what the trick is to install them without leakage? I use a hook to puncture and remove the old seal and then tap the new one in using a socket to push the seal in around the control shaft.

Link or image did not come through. Find another source for parts diagram?

Do you mean the CV axle shaft seal in the differential housing?

good luck

Sorry, I didn't realize I could do jpg files by clicking advanced. I attempted to load a URL link.

This isn't the CV axle, but the transmission. Maybe this picture will help. The seal is item #10. Let me know if you need further clarification.

Recurrent leaking of a seal usually means the shaft being sealed is wobbling due to worn supporting bearing. If leak is intially sealed and develops with time, this scenario seems likely.

If it leaks immediatly, the may be a problem w/ part (OEM?) or damage to the sealing surface (shaft rough).

good luck

When the shift cable pushes & pulls, does that shaft move (other than pure turning)? You might have to watch it while someone shifts. Make sure the car is well supported & chocked.

Thank you for your insight. I'll check these possibilities out with my son this weekend. At least now we have something to look for.

Sorry for the delay, but today was the first day my son has returned home before dark.

The shaft just rotates, with no other movement, no matter how much I push. I guess the bearings aren't the problem here. Can you think of anything else that might cause early demise of this seal? Are there any other things I should check when I install the new seal or other suggestions for the installation?

The other thing that can cause a good new seal to leak, is when the shaft is not smooth where the seal rides. Corrosion? Scratches?

Check the entire outside end of the shaft. If there's something sharp or abrasive, it might damage each new seal as you push it over the sharp piece.

I'll go over the shaft with 300 grit then 600 grit sandpaper before installing the new seal. I also plan to coat the seal in O-ring silicone grease before installing.
