Inside the K181 - take a look
 

Well..... In my expert opinion it looks like the "do-hicky" gear busted which made all of the "thingy-ma-bobs" fly everywhere and break the camshaft. I apologize for using all the highly technical terms, but I don't want anyone to know that I have no idea what I am talking about. Good news is the cylinder walls still show the factory crosshatch, the piston still has the machining marks and the rod journal looks prefect. I have not checked the ring gap yet because I am still planing to replace it all anyway, just need to find the tool box with all my engine hones and cylinder dial meters.

Only ran into one setback getting the engine off when the clutch "springs" shot off and vanished, I did manage to find two of them. I also found that the clutch "flex plate" is cracked. One question I have is how do you get the flywheel off this engine?

Ouch!!! :bigeyes:

:bigthink: I hope the Governor gear in my 169 doesn't look that bad LOL. At least it was nothing too catastrophic. Keep us posted.

Ouch! Typical fragged junk plastic governor gear. It would be nice to try and locate a metal replacement, but they are getting hard to find. Cant say Ive seen a cam break like that, but when things let go in these engines, its always a surprise when you open them up. Thankfully the cylinder is in great shape as you say....looks like a strait forward repair :biggrin2.gif:

Okay then.... So my "do-hicky" gear is the governor gear? Learned something new already. Thanks for the info

As soon as I seen the plastic gear in pieces I knew I was not the first person to have seen one bust. Why would they use plastic? That is some straight up box store Briggs & Stratton stuff there.

I'm pretty sure it boils down to manufacturing cost...but I'm not certain. All the new replacements that are currently available are plastic, unless you can locate a NOS or used metal gear which is obviously more durable. Ive rebuilt engines with both metal and plastic...the plastic ones definitely wont last forever, but they usually last quiet a while.

back to your question...
 

pull that bushing out of the aluminum hub your screen is over, and you will find a large nut. remove the screen, crankshaft nut and washer, then, using a puller( should have 2 threaded holes in flywheel, 180 degrees apart) put some tension on flywheel against crankshaft. I agree with most here. tap on puller and flywheel should come loose fairly easily.

so as not to confuse you
 

looks as if the screen comes off last on a k -181. in your pics there are no screws holding the screen to the flywheel.

Thats an excellent set of photos. Very informative. Cameras, photography and website has come a long way in the last few years.
