Re: Gear case wrench size?
Some on this site use a 3/8" rod coupler instead of the 14mm hex key. In case you're not familiar with it, it looks like a long nut. Although it's for 3/8" rod, the outside dimension is 9/16" (a hair larger than 14mm). On my LT, it's a better fit. Much less expensive and more available, as long as it will fit without gouging out metal.
Also, in the archives I saw a drain funnel made from a plastic 1 qt. oil bottle. I hope I'm not wrong but, I think it was David Shealey's idea. You cut the bottle lengthwise at @ 3/4" tall. I tried it on my last gearbox oil change and liked it better that the hourglass apron. For me, less mess.
