Any suggestions on getting this gear case drain plug unscrewed on A702? The edges have been rounded off before I got it. Thanks

Heat the case around it, or drill it and chip it out a piece at a time. Pipe wrench can be helpful too.

A little heat and a pair of vise grips or weld a nut to the plug should get it out. I never understand when plugs start to get worn why people don't replace them. I have removed a lot of plugs over the years that look like that one.

Thanks Hedgerow, finally came out it was a tough one.

Glad it worked out. Worked at a factory the last 15 years of my working in town live before I finally came home to the farm. Did a lot of P.M.'s in areas I normally didn't work and when I first started there a lot of gear box plugs looked like that too many monkey wrenches around there and people that didn't care. Over time a old guy I worked with on these P.M.'s and myself switch every thing over to a allen based plugs so when the oil needed change every six months it was not a problem. Most of this equipment ran 24/7 only shut down for P.M.
When we would have these shut downs we would work 16 hour days 7 days a week so the last thing you needed was to mess with rounded off plugs.

You were smart! See a problem take the time to fix it. My motto is always look for ways to make your job easier!

The operators in the chemical plant where I spent thirty plus years all carried the dreaded channel lock pliers, which they used for EVERYTHING. I've seen a truckload of rounded off plugs caused by using an inappropriate tool. Taking the time to get and use the right tool pays off in the long run. Glad you got it out.
