Thanks guys. I'll look for
1/4" barb zirk
or
1/8" ptf zirk + R bit + 1/8" ptf tap
...I think I've got that right.

The proper drill size for a 1/8" NPT tap is 11/32", 1/4" NPT tap is 7/16".

If a drive zerk came out.. what about putting inthe correct drive zerk.
you can always 'shrink' the hole 2 ways.
1, take a flat faced hammer and pound on the open hole perfectly square.. the ID of the opening should shrink as you hit it.
2, and can be used in conjunctin with one. 'Stake' the hole.. use a pip punch and make a series of pricks around the hole, just a lil bit back fromthe edge. as you make the prick with the bunch and hammer, you distort the metal where the divot/prick s left.. this ushes metal toward the hole. thus shrinking it.
cant tell you how many loose dive zerks I've 'fixed' by staking them in without pulling them.
once they are out.. i try shrinkingthe hole and a new zerk.. then stake if needed.
