I have used this assembly lube based upon suggestions from the "old wise mechanic" that used to rebuild Craftsman ratchets on the spot when the Sears & Roebuck Brick and Mortar stores were thriving in the '90s and early 2000s.
Absolutely, these are not sealed. Some manual transmissions use ATF and it holds up fine, no need to take it apart just toss it on a jug with ATF covering the head of the ratchet over the weekend. Drain it off, wipe it down and work all week with it.
