While doing my 50 hour maintenance I noticed I had busted off two Zerk fittings on my 7308 loader. I got the one on the side pin out ok, but the one that the quick attach locking pin slides thru seems to be a press fit? Are those metric or standard fittings?

Dutch74, there are now so many zerk sizes that only God would know for sure. Yes there are drive in and metric zerks. In the good ole days 99% of all zerks were 1/8 inch pipe thread. If you can get the broken one out without destroying it take both stubs along to a farm supply store and find the ones that match. If you have to destroy the one surely your dealers parts book or tech manual would show the correct size. Frank. ....

The small threaded zerks are threaded into a 1/4-28 threaded hole. The larger ones are 1/8 NTPT as stated before. If you are removing a treaded zerk, drill the center out to fit the correct size EZ-Out. Left hand drill bits work great here because if the zerk breaks loose, it will just back it's self right out. If you are trying to get a press fit zerk out, try the EZ-Out method first, then if that doesn't work you will have to drill it right to size. The nice thing about getting zerks out is there is already a hole in the center to guide the drill. ....
