If I’m greasing my zerk fittings, is it better to take them out and clean them first?
Just clean them of the dirt and then just use the grease gun . No need to remove them .
Wipe the outside with a rag, grease the joint, wipe the excess.
There is a little ball at the end that only allows grease under pressure to enter, no worries. There is a greater chance of contamination if removed, my thought.
If you have problems injecting grease,
Get the Ramo-Matic zerk fitting cleaner.
Yup, the only thing I will add is that they all are not screwed in. Some are pressed/knocked/pounded in so you’ll ruin them taking them out. I used to install zirks in wheels during my school years-lots and lots of them.
Wow, that’s what I call advice. Much thanks, folks!
