[TowerTalk] Zerk fitting for MA-40

[Don W7WLL]

IMHO, use an EZ-out, inexpensive and work. I've never seen a Zerk that was 
not tapped but surely could exist. Mine are tapped. Even if you have to end 
up drilling it out you can rethread. Just keep the drill size of the EZ-Out 
doesn't work less that the tap size specified for the Zerk thread. Be sure 
to THROUGHLY flush out the fitting hole, don't want any chips or crud 
getting into the bearing. You can't put to much grease in, you should see it 
oozing out before stopping the greasing.

Good information everybody.  And quick too!  Thank you.

One more question.  Removing the remains of the Zeck fitting, would
anybody know if this is tapped or pressed?
