Hi guys

Workin on replacing the oil seal. I’m having difficulty getting old one out & the part looks different than what’s up on truck. Is there a cap that covers oil seal? It’s not shown in shop manual.

51 MERC-CT · 10-28-2020, 01:20 PM

There are a few different oil seals, which one are you talkin' about?

adileo · 10-28-2020, 01:52 PM

Thanks- The part number is M-4676.

Is there a deflector / cap over it? If yes is it presses on or screw in. See pic to left above.

Bob C · 10-28-2020, 02:01 PM

The shop manual doesn't show a deflector, just the seal and companion flange.

adileo · 10-28-2020, 02:06 PM

I know but maybe this rear was changed out. See pic it has a cap - deflector or something I can’t get off....

How did get the plate or seal out?

Do I need the deflector if I destroy it getting it out?

alanwoodieman · 10-28-2020, 03:47 PM

drill two hole on opposite sides--run a large sheet metal screw in and pry out seal using the alternate holes. always remember the "edge" of the seal goes against the fluid side

Bob C · 10-28-2020, 03:53 PM

What deflector? Are you asking about the oil slinger that's behind the seal?

adileo · 10-28-2020, 04:00 PM

No please see pic on left. It’s in front

51 MERC-CT · 10-28-2020, 04:16 PM

Does the pic on left show the shield and bearing in place with the axle removed?

adileo · 10-28-2020, 04:20 PM

Hi no

The pic shows the view with drive shaft, companion flange & nut removed.

This now becomes a little clearer (it's the pinion shaft seal not an axle seal)
It should pry off utilizing the outer seam.

This from shop manual:

adileo · 10-28-2020, 05:35 PM

Thanks all! It was confusing that the replacement didn’t look like what I was seeing on the truck. What I’ve gathered is the old original seal had a metal lip. The replacement doesn’t and it’s not needed. So I can now hack at it tomorrow.

JSeery · 10-28-2020, 06:07 PM

Just remember you're messing with the pre-load on the pinion. Need to mark the nut well and be sure it gets back to the same location.

adileo · 10-28-2020, 06:23 PM

Jerry thanks. I didn’t mark it. The book says tork 140-180.

Two questions. Since I still haven’t removed the oil seal. Should I put the nut and yoke back tork and mark? Or too late and just tork to specs?

JSeery · 10-28-2020, 06:46 PM

I think it's to late to correct it now. For future reference, always mark a pinion nut before you remove it. The torque spec is all you have to go on now, most likely will be ok.

My bad. Thanks!

Ross F-1 · 10-28-2020, 08:23 PM

I would absolutely go with torque to specs rather than the position the nut was in 68 yrs ago when it had brand new bearings. Although you may end up backing off to get the cotter pin in.
