Got a Super A this past weekend and when the guy brought it to the house he said "It runs, I drove it on the trailer". Well.......we have all heard that before. We just had to believe the guy though as he seemed innocent enough and was real nice so I said "OK, let me grab a battery and see what she sounds like". It would fire and hit right off, but not run and would just pop and fuss like the timing was off. Decided that was the case and made a deal for a couple pieces of Cub Fast Hitch Equipment that he wanted.
Later that evening I wanted to go out and see if we could get her running, so I begun by doing a compression test (125 psi across all cyls), checking the timing and the output of the Magneto. Had spark and it also has a "rebuilt" carburetor, so I tried it. Nothing, not even a pop. Took off the cap to set the timing to #1 TDC. Noticed that the rotor button wasn't turning when my uncle turned the crank. Hmm....weird. Took off the mag to replace with a distributor thinking it is maybe something with the mag. Before we installed the distributor, I decided to turn the engine over with the crank watching the notches in the governor. NOT TURNING! I pushed in on the governor (notches) and it started turning with the crank. My uncle said that it wasn't meshing with the governor teeth for some reason and we thought maybe they were rounded off or ground back a little.
We pulled the radiator to get a good look at the governor. Took it off and here is what we found...........
What the heck!?!? Almost 1/4 of the teeth on the Governor are sheared off nearly FLAT!! How did this happen. From there we took a look at the camshaft timing gear (what we could see of it). As we turned the engine with the crank, we saw a just a few teeth with some chipped or broken places. Nothing like the governor gear though. Also, as turning the engine with the crank, I noticed where the cam gear was "slipping" in some places and not turning in syncronization like it should.
This is where we decided to pull the front bolster with the axle and pull the front engine cover because we knew the camshaft timing gear needed replacing also. Not that
bad......but oh no, it gets worse. Notice the chipped teeth near the governor hole and near the hydraulic pump gear. Pulled the cover, then found this...........
It looks like not only is she gonna get a new Governor, a New Camshaft Timing Gear, but a New Crankshaft as well. The teeth on the crankshaft gear look to be fine, as well as the teeth on the hydraulic pump gear.
Ugghhhh.....oh, the work ahead.
It's ok though, still not a bad deal as the rest of the tractor seems
to be in decent shape. It can all be fixed correctly, I just hate to see someone "sham" up a tractor.
