Troy built mower honda 160 engine oil leak around governer shaft. no oil seal but shows one on parts breakdown. Can not find part number for shown seal.

probably oil seal or weak gasket engines build up pressure if theres a weak spot on gasket or seals it will find the spot .it can also be the pcv valve ,pollution control valve

over filled or bad seal. or someone tilted over engine, 90 degrees. or more.

If you look at the bottom of the engine, if you see oil on the large shaft coming out of the engine where the blade is attached, the PTO or crankshaft seal is leaking. It can be replace without taking the engine apart, but you'll need to remove the blade and adapter from the crankshaft, which can be difficult without the proper tools. You'll also have to remove the old seal, with a seal puller, or by using a couple self-tapping sheet metal screws into the outer metal part of the seal. You then would pry on the screw heads to remove the seal. Replace with a new one after cleaning out the bottom of the crankcase. Clean the PTO so that the new seal is not damaged as it is slid into place. You can use a length of plastic pipe to drive the new seal into place. Replace adapter and blade. Check oil level before use.
Oh, be sure it is not the drain plug, as it may have been left a bit loose if the oil was recently changed.

The agitater shaft that the beater attaches to is bent and needs to be replaced. It's easy to do . You should replace the shaft , pin, and seal above it. You may also want to replace the part the shaft mount through, to stop oil leak. You can google the model number and find a parts breakdown for the part numbers .

Bad or defectived shaft seal. Replace it or take it back where you bought it.

it's on the same side as the muffler near the bottom of the engine. carefull with the oil if you run it before you change the oil as it will be HOT!!!...good luck

Not sure what a pont is, or what motor you have, but on some of the Troy built small engines from Honda the geniuses designed the motor with no drain plug. You have to tilt or flip the engine over to drain oil out the filler

It is toast you fried the crank/connecting rod, by running it low on oil.
Its hard to say what caused the oil leak, but now it is ruined.

there is a possibility the c oil is bad, pull the plug and with wire attached pull cord to see if any spark

Just about any engine with a 3/4" horizontal shaft that is internally threaded on the end and has the four bolt mounting pattern around the shaft will work. I have gone to Harbor Freight and purchased their 6.5 H.P. engine that is a Honda clone and it will work fine and only costs $100-150 dollars. The only difference is that it uses a metric bolt to hold the pulley on the shaft,the four mounting bolts are metric and you have to disconnect the low oil shutoff or the engine will die when you are tilling deep. It is a good low cost option for the Horse tillers.
