Did a little work on that 1A tiller I picked up last week. I know the chains are just supposed to be run in grease but the only way I can find to lube them is to take the whole thing apart. Well that's not gonna happen so I drilled and tapped a 1/8" pipe thread into the case at the top near the input shaft and pumped about 1/2 gal of 80/90 gear oil that I had laying around into the case. It now turns nice and free. So far it's not leaking but I honestly don't care if it does. I'll just put more oil in it. No pics at the moment it's hanging from my engine hoist with a bucket under it incase it leaks. Gotta check out the right angle gear box next. Then the 149 and see if the whole mess works. If it seems OK then I need to find some tines for it, my tines are pretty well spent and factory stuff shows as NLA. Guess Cub figures you'll just buy a new tractor and tiller yep that's not going to happen with this boy.
