I'm trying to drain/change the tran oil in my 915, and the drain plug won't budge an inch. I'm using the proper hex nut/ratchet (17mm), but the darn thing will not move. Any suggestions...are they always this tough to remove?

search here and on Pelican

DO NOT open it or try to w/o getting the fill plug loose first. You posted on Pelican about that, right? If not self-evident yet, just think about what you'll do with a drained trans. you cannot refill.

fill plug is out...this isn't my daily driver, so I'm not at the mercy of these stubborn plugs I posted over on Pelican as well....

OK - do a search on Pelican for various ways people have gotten these out - folks have tried everything except for C-4... heat works well if you have a torch

she's out...what a pain the a**. Leverage is the key (and a little heat). I ended up heating the case a little bit, and let it cool down. Then I used an old torque wrench (much longer handle and stronger than the 3/8 wrench I was using). Now off to replace the oil...

For future use, having a couple of three foot long pieces of galvanized pipe, of sufficient ID to fit over various wrenches/breaker bars really helps. NEVER use those pipes to re-install hardware!

Pete, good idea...I feel like an idiot for not using a 1/2 socket wrench in the first place. I just assumed since the hex head I was using fit a 3/8 wrench...that's what I should use. Lesson learned...

Actually I used a 3/8 inch socket as well. I have a 3/8 to 1/2 adaptor and have an old 1/2 inch torch wrench that is now a breaker bar. It works great. I had more of a problem getting the filler plug out first. I could not get enough torch and keep the socket flush. I ended up using a 2 foot long extension so I was turning the plug from outside the rear wheel well. The first hard crank broke it loose and a piece of cake from there on in...
