Clutch spring hack

It's mainly a con I think. I worked with a bloke who leaned hard into compliance, the book, the manual etc. I remember watching him twat away a morning revving and idling a new saw. He greased the nose of Husky/Oregon bars. I'm convinced that's the beginning of the end of them because all he talked about was nose sprockets shitting themselves. Meanwhile plenty of bars (i.e. Stihl ones) that never see grease, still work.

My theory is that grease attracts and holds dirt, which causes bar nose failure.

Yep. That. I've probably just signed my 661's death warrant by putting the caged bearing in with some chain oil just now. I shit you not, the rollers were spinning freely before I lubed it and then bound up with the oil.

I fycking hate the thing anyway. Heavy, loud bastard. Fcxk off. I want a 40 foot birch I can do with a zingy little 2511 and a packet of sweets.

You may be on to something there. At this time of the year my workshop is full with stihl long reach trimmers with goosed gearboxes.

 

For reference sake, there are two points to grease on all, maybe not all but most articulated hedge trimmers. The main gearbox and the one that no one does which costs them a lot of money is on top of the head, the bit that doesn't move. These get neglected and contaminated with water.

 

I’m sure you know this, and you’re just being facetious with the resident drunken anarchist.  But for the benefit of those more easily led astray…

 

These don’t have a proper seal, just a loose bit of plastic against the end where the blades protrude from. It’s not like a round shaft where a rotary lipped seal can easily form a total seal against the oil. 
 

I laughed at his post because although he have have filled it with chain oil, he hasn’t yet realised that there’s none left inside it unless he’s stored it standing up for the last 15 years and not used it. 
 

Your workshop is full of trimmers for the reason that people assume once it’s ’filled with grease’ then it’s good. What actually happens is that they get hot with use, the grease gets liquid, and escapes from the blade end. And then it’s not replaced. What’s left inside emulsifies with the loss of the oil component of the grease through heat and ends up in the familiar waxy looking crap everywhere in the head except where it’s needed- on the gears and in particular the con rod bearings. 
 

stick a grease nipple into the fitting and grease it every other time it’s used and they will not fail.

Been saying that for years . Acts like a lapping paste .

I’d be interested if full time foresters/fallers grease their nose sprockets.

 

Never greased a clutch bearing in my life either
