Ok guys. I was given a 1974 140 parts tractor to complete my 1972 140, and I have the motor removed. As for the transmission, I'm having issues with removing the lug nuts. On the later 140's, you screw on a nut to hold the wheels to the brake hub studs. Anyhow, on the left rear, there are three nuts that are rusted fast to the lugs, and I've been soaking them with penetrating oil for the past week and a half, tapping the nuts with a hammer and screw driver each day. I tried again tonight to try and get the nuts off, and just about gave myself a hernia. These suckers are on there tight. So far, I've tried a 1/2" impact gun, heat, and a 1/2" socket wrench with the big breaker bar, and they aren't even trying to budge. Any recommendations out there that I might try and use to get these things off? I don't want to ruin the studs, but I guess if that is the only thing left to do, then so be it.
The tires on this tractor are in need of tubes, but I'm not looking forward to installing tubes while the wheel is still mounted to the tractor. I also need to replace the brake on this same rear, but I can't do that until I can get the lugs and wheel off. The sooner I get this tractor disassembled, and the 72 140 completed, the sooner I can roto-till the garden before fall sets in.
