Great video thanks for explaining the push in type!

[Michael-twrv]

Excellent video! Informative, comprehensive and well prepared and presented.

[rotfan]

Thanks, I wasn’t sure about the push type. But I saw a rounded outer edge and wasn’t sure at all how to get it out. Thanks for your video.

Possibly also worth mentioning that some fittings are Metric threaded / sized and others may be Imperial threaded / sized. Nice video! 😀

[parkland]

Thanks for the video. I take it there are metric threaded fittings to confuse things as well?

PERFECT! Went to O'Reilly's and they didn't know the difference's. Went to NAPA, older gent educated me on the "tap in" type. Voila'.

You can also try to heat the fitting. Sometimes old grease gets hard and by heating it, it helps to move things in there. It has worked for me in the past.

Great video! Just the information I needed thank you very much and God bless

[lovetrinity]

so glad i ended up on this video first. I like that I could use the tools I have at home to change the fittings instead of getting a special tool. I hate that everything is common sense, but you don't realize it till after seeing it done by someone else, like using those common tools to swap those fittings out. you made it look like a piece of cake. lol Thanks for the tutorial! Liked

What tool set would you recommend for having in a rock truck to change the screw type fittings ?

[tomedgar]

Nope, most of the time they don’t need replacing. Some greases turn hard and won’t allow new grease in. Pull the fitting off and soak them in diesel or kerosene for a couple of hours and they will work just fine. I prefer to use an ultrasonic cleaner with kerosene. Cleans them up in twenty minutes.

I hope someone didn't ask this in the previous 50 comments (no way to search when there are so many comments?) I removed a drive in (press in) grease fitting. Concerned that the hole is now larger than the original from pulling it out. Should I replace with another press-in or drive-in fitting? Seems to me that they would make self-threading fittings that would cut into the existing press in hole for a better install. I could only find 1/4-28 thread cutting zerk (grease) fittings. These are too small and don't bite into the hole for a press in. Have you ever heard of 5/16 "thread cutting" fittings? I can't seem to find any. Please let me know if I should just use 5/16 drive in fitting to replace. Thank you!

[rodkramer]

Do the drive in fittings have all the same size end that gets driven in?

[johnwyman]

So how do we remove and replace angled press in grease zerks?

[VINTAGE-AMERICANA]

1960 Buick, 15 zirts, 2 won't take grease - thanks for advise

[JoshAllenGoated]

How do you remove a broken press fit fitting?

[jstpsgthru]

Will tapping cause a problem from filings? Would it be appropriate to try the next larger straight drive, or could that be destructive?

[KelliNorgaard-dzmf]

Can you change out a drive in zirt and upgrade to a screw in zirt?

[williamokrasinski]

Thanks for the tutorial, but one piece missing for the odd nut like me. My 37 YO JD316 38" mower deck hub zerk failed and lets grease back out the nipple. It is press in and I pulled it out. Hole Dia. .188". I can drill and tap for small threaded zerk but can't find out what thread pitch for correct tap. Some said 1/4-20 but I think 1/4-28. Any help for us dummies who want to install a threaded zerk in place of push in ???
