Yeah, all was going well - both output shaft seals went in without a hitch, eazy-peazy. Installed a brass (bronze?) bushing at the shifter console too. Then I manage to drop the old input shaft seal INTO the freakin' case, trying to get a screwdriver to pierce the seal. I had previously tried to drill the seal for a sheetmetal screw but the bit was too short to reach because of the drill's bulky battery section. So, it's FAIL ARMY for me on this one (IMG:style_emoticons/default/biggrin.gif)

Anyway.. what are the options now - full tear down? Can one of the side plate's come off and allow access for old seal retrieval? Tie it to my boat so I don't drift down current?

Assuming you just punched the seal into the differential cavity; you can remove the side cover to the differential.

Beware: the side cover is sealed with a large o-ring. Plan on replacing that. Adding gasket material or RTV under the cover could affect ring and pinion mesh. Just plan ahead and replace the O-ring gasket. I’d also have at least one output shaft seal on hand - just incase you damage one of those while removing the diff.

Doesn't sound too bad I guess. Will the Diff. need to come out ?

Only God knows.

Once the side cover is off I’d bet you can fish it out one way or another.

If you can fish it out with a soft metal, I used a coat hanger, didn’t damage the shaft at all, I believe it is hardened. Maybe a length of mig wire? Wasn’t easy needed a lot of pulling. Good luck.

Am I calling it the wrong thing? It most certainly will fall in.. into the bore, yes it's still around the shaft but inside the bore - after aggressive screwdriver work.

I did as @Superhawk996 suggested and popped the cover off of the diff area (thanks for the encouragement).. that's the seal at the end of my screwdriver

And a shot after I cut the seal off of the input shaft.

So now we know - if any other doofus does what I did trying to get the seal out, it can be accessed by removing the diff cover.

Large O-ring ordered!

Yes, that's the seal.
Accidentally pushed mine into the case, never bothered to remove it, just added a new seal.

It can't go anywhere, it'll just catch a ride on the shaft until the next time someone opens up the case.

Which you did, but i did not.

(IMG:style_emoticons/default/laugh.gif) glad you got it easily.

I couldn’t remember off the top of my head whether the input shaft crossed in front of or behind the ring gear and whether you would have to remove the differential.

As someone that’s recently assembled an entire car, that seems to be the theme with a 914.

True enough. I guess we get to enjoy it. (IMG:style_emoticons/default/headbang.gif)
