How do you drill out the 582 lord mounts on a mod IV?

I'm glad you got your answer on the other thread, Jay. I was in the process of composing a reply that you not try to do it all in one cut, but go up 1/64" at a time, when someone who knew what he was talking about pointed you in the right direction. Good luck!

They are next to impossible to drill without damaging the rubber just use smaller bolts and sleeve the bearer with a bit of moly tube

I got two done at lunch with our fancy drill press. I say fancy as it's almost a milling machine with its adjustable bed. I just stepped up the drill sizes until I hit 5/16". The first one was close to center and the second one was dead on. I used window cleaner as a coolant, it was handy, and did no damage to the rubber. Just gotta go slow and steady. I hope to get the other two done tomorrow.

Never heard of window cleaner as a coolant, but glad it's working out. Like most of these things, once you learn the trick you wonder why it seemed hard.

I got the other two drilled dead on center today. The window cleaner was the only water based spray I had on hand. Oil is hard on rubber, so I used the window cleaner. Works great!
