Because I used the Rubber Gasket Cement when I installed the Seal it did not harden. That made it easier to get out.

I the past I used to coat Seal bores and the outside of seals with Red Loctite before I Installed them. But, that was when someone else was paying for the Loctite.

In any event I am thankful that the new Seal came out as easy as it did (and I was able to reuse it) because the Old one took more drastic destructive measures to get it out.

What was the purpose of the red loctite on oil seals?

Seals do not always come out easily. In the case of the differential Seals I had to Hammer a Screwdriver between the seal and the Bore to loosen the Seal. (You will never see me recommend this method to someone because you need to really be careful doing it. Also in this particular case I did it at the highest point I could and Differential Oil is not under pressure and is thick so there is very little chance it is going to leak.)

That often nicks up the Bore. You can dress down the high spots but there is low spots to deal with. Sealant takes care of that.

Also when I worked as a Mechanic I did everything possible to insure that what I worked on was not returned for any reason under warranty. For me sealants were insurance against the off chance of something leaking.

Also the outer surface of a lot of Seals is just plain Steel. You do not want to install a seal like that without some sort of Sealant.

When something comes back to the Shop under warranty the Shop pays the Mechanic to fix it for Free; they also lose the Profit the Mechanic could have made for the shop while he was doing the Free fix, and often they lose a Customer.
The Shop also loses the Cost of parts and materials used to do the Fix.

Well, the above sort of worked once I gave up on the fact that I was not going to meet the deadline I had set for Myself I was able to relax and eventually figured out what might work.
Unforunately for Me I had no Beer in the House. I might go to a Bar once in a while but I seldom Drink at Home.

When you are not concerned about damaging the seal, a small slide hammer threaded into the metal face of the seal always pops them out. Sometimes you may need a couple of opposing holes popped sequentially, but I've never had it fail. And on recessed seals with part of a shaft sticking through, it's the only way you will ever get them out.

That might have worked well on these Seals because they are Big and there is at least 1/2" between the Bore and the Lip if the Seal. Also the Seal had some decent Metal on it.
