Smoked a clutch on my tiller....

[smstonypoint]

This has been fun to watch. I didn't realize tillers were so serious ;-)

Engineers are a much maligned faction in this thread. I am not a disputant, and I am not yet heated, but fear the slip clutch springs were heated. I think they should be freed, and their length as free springs checked, lest the compressed length check become invalidated, and iterative empirical tightening must proceed henceforth.

I'm far from "heated" or "provoked", more like "amused" and/or "entertained". It's all so incredible that someone would take this so seriously, or for that matter, believe everything is either black or white, with no middle ground.

Not everything in life is taken straight from the text book. There lies the major difference between an engineer and a GOOD engineer.....The ability to differentiate between what we expect to happen on the drawing board and what does happens in the real world.

I prefer to take WHAT I see as real in this world, then apply what I know to explain WHY, rather than taking what I THINK I know and using THAT to build certain expectations that often times aren't attainable/reasonable.

To each his own I suppose.....

That might sum up the difference between a shear pin and a slip clutch. Shear pins are a black and white solution. A slip clutch allows for lots of middle ground or gray area, and even some gray smoke at times. There's no way to watch where you are driving AND watch the rear implement 100% of the time. I've smoked mine enough times to know they work well, protect the gear box and PTO, and still give me time to react several seconds late and not harm anything. I like how forgiving they are.

To the OP. The chances are your clutch will be fine. If it stops smoking and makes grating sounds then it's replacement time.

On slip clutches is the force required to make them slip the same as that required to keep them slipping?

Well said! :thumbsup:

Yeah.....maybe not. My experience shows that once you get the clutch "warmed up" it's gonna slip progressively easier. Because I didn't have wrenches to make the needed adjustments...nor the patience to let things get cooled down.....I got the clutch severely overheated when I thought I could finish my job with the now very hot clutch. No way!

I kinda figured the lining was toast...but it works fine again. It's not the end of time....Even if one were to ruin the clutch disc.....$50 and your back in biz. Schmidt happens!

We have a BINGO!

No, it takes more force to start them to slipping, and a good deal of force reduction to get them to stop again. Before they are slipping, the coefficient of static friction would apply, and afterwards, the coefficient of dynamic friction would apply.

Youre going to have to stop knowing stuf an engineer would know. Some are highly threatened by it. Its even worse if you point out anything to them. They know better than the truth ... or else the truth is not valid. :confused2:
