Stripped threads

Maine_Polack · Nov 16, 2006

I have a grease fitting "hole" that is stripped out. I can push the zerk in and out the hole easily.

I do not want to take the thing apart, or I would and tap for the larger zerk.

Can purchase a thread insert, but also have to get kit, $25,...Naw.

Any ideas/tips would be appreciated

I have found some barbed grease fittings at the auto parts store. Finding one that is the proper size that will fit into the hole and be snug enough to work, will be the hard part.

They sell self-tapping zerks. We use them on our loaders for that reason. They work very well when you find the correct size. Might be the same/similar to Dusty's recommendation.

They also make drive in grease fitting's. They are installed by tapping them in with a hammer. Might work in this situation or you can use the thread forming type already mentioned.

Thanks for the info! I did call a couple of local Auto part stores before I posted my question. They did not have a clue.

Went to the big city, (Bangor), today, and ran into the same thing.

I will keep hunting.

It sure is nice to be able to tap such a vast knowledge base, as found on this site. I truly appreciate all the input

Check the diameter of the hole using a drill bit and post it. I will check my supply and also in town. If I can find one, I will put it into the mail to you. Just let me know what size.

Very nice of you to do that. Will check the size tomorrow. Dark now.

Send me a PM to remind me. I might not see the post.

I believe you can get zerk fittings with metric thread. Might be able to use a slightly larger metric. If you try this don't try to tap it or anything, just turn it in and leave it.

I had a zerk that would not take grease, I took the zerk out and cleaned it out and grease went through it until I put it back in the part, then it would not take grease again, what now?
