Vacuum Oil Extraction

[Bruce of MN]

I have used a pump like this to empty my Triumph TR4A differential (no drain plug for some reason).

Not sure how the tube would get past the baffles in the oil filler tube on an A, though.

If a problem, just remove the oil filler tube.

The tube in my replacement uncracked block is in Very securely. It looks like a process like rolling tubes in a heat exchanger was used. Others should be luckier.
