When changing gears in a Hewland transmission we used gasoline on a rag to wipe off the Blue Hylomar used to seal the rear cover on the trans. Good against hot gear oil.

Gasoline, not so much.

Locktite 515or Locktite 510 – I have used both. 510 has a higher temperature operating range.  400F vs 300F. Just don’t get to much if any on the long ¼” bolts. Makes them very hard to back out. Once the bolts are removed only a light tap with a rubber mallet is required. A little goes a long way so don’t over fill. Any squeeze out on the exterior will also be on the inside. It will harden into a solid ring and looks really strange the first time you dissemble.

3. When you do get 'em apart, there are sealants that don't harden...
