How to lift a Kohler

You didn't get older, you got smarter.

Come to think of it, does anyone have a junk head and some weights lying around.....???? hmmm.....

Actually...I have a spare head from an M18 laying in the shop.

engineers and mechanics seldom get along.

Thats because everything from an engineering standpoint works great on a piece of paper and a good mechanic knows better.

Couldn't agree more.

I don't know how many times I've seen engineering have epic fails when their "program" or "piece of paper" didn't stand up to the practical application.

No offense to the engineers here. CAD you have proven to me to be the most "practical" engineer I have ever met. You have yet to produce something I strongly disagree with. You seem to have used your skills, or background to actually build things on your own. You are one of the few who have both the knowledge base (engineering) and the mechanical aptitude to put your own ideas into actual products that work. Hats off to you.

I get along fine with mechanics Though I dont really work in mechanical engineering. Common sense plays a roll in good engineering, finding the perfect balance between weight/ material saving and strength isnt always easy, and it becomes even harder when being pushed to save company's every dollar possible. I'm a decent mechanic, but I don't think I could design something like a diesel injector pump and have it work, lol. At the end of the day there are a lot of good mechanics and engineers that use common sense and make some great stuff.

On the topic, the engineer in me says the numbers look good and i can lift the engine fine, my common sense says that head is soft metal, if it rocks or get pulled sideways it could pull the threads out, and the mechanic in me says I guess I'll take another 5 minutes and use two head bolts so I don't have to replace the head if something goes wrong. No offense to anyone, that's just how I see it.

Yep. I was a farmer before I was an engineer. Then a motorhead. Then a machinist. Then an engineer. Now I dont even do engineering.

But I have met a lot of very practical engineers that can get the rubber on the road. And I have met some that are so theoretical you wouldnt want to test pilot anything they have designed.

At the same time I have met some great, practical mechanics with fantastic experience and wisdom. And I have met some that are full of hot air and I wouldnt let them come near my equipment with a 10ft pole.

Im not going to generalize based on an arbitrary label put on either group.

Having said that, Im looking forward to seeing how much weight jimbob can hang on his scrap head.....

(oh, for the record this wouldnt be my choice of how to lift an engine. But I like the philosophical debate (kinda like wallowing in the mud with pigs))

We get the engineer type customers here, most of them are sensible guys. The ones that make me laugh are the ones who claim to know it all, "but I dont have time to fix this" lol. My kohler 12 also has a lifting bracket there from the factory, it worked well. Thanks, TB

100,000lbs. huh. I must be a lot stronger than I though, because I've twisted a lot of them out with a short handle rachet before......

You go right ahead and do it that way if you want, but in the words of Jerry Clower..... "I ain't gonna do it!".

big difference between torque (twisting) and pulling (pressure). If we crank the engine without supplying fuel or ignition (so there's no combustion), the compression stroke of the piston produces a modest pressure peak (perhaps 120 PSI) right at TDC. On the other hand, if we provide a combustible fuel/air mixture combustion causes the pressure to build to a much higher value - typically 800 PSI in a normally-aspirated engine. Just sayin. Oh, by the way thanks for the discussion, I appreciate your view and you know your stuff.
