What is the size of a typical oil drain plug on a wood splitter, is it 1/4 inch? Last year I used a hand siphon to remove the old oil (don't like it) since I don't have that size wrench I would need to pick one up if it's a 1/4 inch.
What engine? Most are 1/4" NPT pipe plugs with 3/8" or 7/16" square drives. An open end wrench will drive it but a double square 8 pt socket would be even better. Sears usually has them on the shelf if you look carefully.
My b &s motor allows me to only use the socket wrench without any socket on it. There is 2 locations to remove oil, and luckily there is a hole in the frame below the motor. Did u look well in between the axle and base of motor. Mine was alittle tricky to find.Not sure your setup is the same as mine.
Sounds like a vertical shaft engine. Like the Huskee 22 ton. Those have a lawn mower style plug in the bottom of the engine as you describe.
After doing an oil change on my Huskee, I bought one of these. Works great too. http://www.liquivac.com/
$55.00 at Tractor Supply....Lowes has it at $29.98. I'll grab the liqivac today, the Generator will be the first thing I use it on, hopefully both splitters by the 26th of October. The oil in the MTD is still looking good (I'll still change it) but the 24 ton splitter needs changing before running it again.
I thought we were avoiding siphons/evacuators? Heck I would've told you to do the liqui-vac right off then! I use an evacuator in every possible situation, and avoid drain plugs like the plague.
Harbor Freight has a transfer pump on sale for $5 - $10 all the time. Works well. I have used them to adjust the automatic transmission fluid level, remove/change windshield fluid from summer to winter mixes, ...
I had bought this after your post, I finally used it for the first time today, it works great. Thanks
