With winter fast approaching, I have been telling myself "No more painting. I need to switch to doing work inside the house, like engine repairs." Then I dragged home a Simpson's Supremacy. I have been looking for one for quite a while, so when this one popped up, I jumped on it. Paid way more than I have for other walk behinds in similar condition ($60), but (sing alone if you know the words) I didn't have one. Sorry, no before photos.
This tractor came without an ID tag, but with the wrong engine (an ACN built in January 1959), so dating it is difficult. What I know is that it has the 4-stud engine carrier (SN 600 to 4171) and the B127-301 gear case (SN 1244 and up). That should put it somewhere between SN 1244 and 4171.
It had sat outside in the rain with the crank case breather cap missing, so I knew the crankcase would be full of water. I pulled the engine to remove the water & get it running again. I drained the chocolate milk & removed the base to remove the sludge. Then I cleaned & set the points. Then it was the carb & sediment bowl. Finally, I replaced the spark plug. It runs fine, but that isn't the problem.
The problem is that once I had the engine off, I noticed there was a lot of axle play in the housings. The wheels needed to come off anyway because they were leaking Calcium Chloride all over the floor. So, with that much removed, it just seems logical to remove the gear case cover and pull the axle to see just how bad things really are. The axle bushings are shot, so dirt got between the bushings & the axle and wore grooves into the axle and elongated the hole in the gear case cover. Once the axle started to flop around, the oil seal soon failed and its metal housing wore another groove in the axle. The misaligned axle burred the edges of the final drive gear. A file took care of them.
All that means that I need to get an axle made, have the cover hole over-sized & bushed, and install a new oil seal & a couple of bushings. Seeing as it is all in pieces, I might as well paint it. I need to paint the rims before the tires go back on anyway. From water in the engine to a complete restoration.
