What are the chances that it doesn't leak?

Tim,

Others, with more experience than I, will be along soon with thoughts. My take is that the chances it doesn't leak are between these two extremes --- slim and none.

I bet you can take a dental pick and pull that seal out.

I didn't even bother looking for slim...figured he is in or on his way to OH.

Looked around on my cluttered shelf and found an extra tst "reworked" retainer. :D

after I was offered a replacement by one of our gracious members :worthy:

Installed with a new gasket and some right stuff,

Plan to send the original to tst for a new seal and will ask that he report his findings.
Any non-cash wagers?

Tim, since you have it off now see if you can push the seal out with your fingers, bet you can.

won't budge....The gasket came off intact, not sure if it is original part or not.

Hi,
I don't know if you oiled the crankshaft where the seal runs or not. If not, squirt a little motor oil into the seal, at the lip from the outside, probably better than no oil.

it is always a good practice with any seal to pack some grease on the inside to make sure the spring does not pop out when the seal is installed, also it lubes the seal to save it from damage from something turning it dry, I have many cubs apart with new seals leaking and the spring is knocked off

Thank you for the grease packing tip. I did put oil on the crankshaft and seal before installing. And wouldn't you know it, the spring popped out while installing. Fortunately, tst mentioned it in his above post so I was looking for it and fixed it.

Adjusted the valves, for the first time ever, and all of them needed adjusting. It was a lot easier than expected. :)
47 valve adjusted.jpg

Sprayed some seafoam into and onto the valves, springs, tappets, etc. and replaced the cover/gasket for a good soaking while I tend to other repairs.

Removed the governor primarily to replace this guy,
47 governor seal original;.jpg


and while disassembling I noticed a recurring yellowish white paint dob on most all the external parts, including the oil pump and retainer. As you can see on the governor, there is the same color of paint on each item, like someone was marking the parts with their finger dobbed with paint.

There is a dob on the diff housing and rear tube extension that looks like a spray can application. Same yellowish white color.

Was this a quality control check during assembly?

edit; or, perhaps someone disassembled it at some point, along with other cub(s), and did not want to mix tractor parts.

I presume the odds of the front crankshaft seal not leaking are the same as the rear, so it is getting replaced too.

The only seal left to replace is this one,

which does not appear to be leaking oil into the magneto, so I'm thinking about leaving it alone, for now, until I change my mind, later today. :?

Could not figure out how to remove front crankshaft seal while on the tractor so I removed the front cover,
47 front cover off.jpg

popped out the old seal and installed a new one,
47 front cover new seal.jpg

and replaced the governor seal.

With the cover off, I was able to confirm the gears are aligned properly at TDC and inspect the gears, etc.

Installed the governor, making sure the dots were aligned. Everything looks good, no broken parts in the bottom of oil pan, just black oil :D

If you haven't already installed the front cover, the manual says to NOT tighten the bolts down until the front pulley has been installed. This ensures the cover/seal is centered on the pulley, and reduces the chance of leaking.

Dale,

Thank you for that long distance reminder!!!! I had the front cover torqued down along with the governor and read your post BEFORE installing the pulley. I hope you are having an awesome time, sure you are.
