The nose sprocket on my bar seized today

[manual]

SRT-Tech , a thin film of oil will lubricate the roller bearings well . Not all the oil is flung away from the rollers .

Yes It will,
I'm taking an underdog stand on this thread.
IF you are doing alot of plunge cutting. It would be best to greese your tip.
Some people feel comfortable greesing there tip. Let them.
there is some help full tips here in this thread for the guy who likes to use greese.
why would they put a greese hole on the bar if nobody uses it ?

Good post.

I only cut hardwoods and always greased my oregon tips for years before coming to this site. I quit greasing and lost two tips in two months. The stihl bars don't have a grease hole, and have metal plates between the bar and the sprocket to keep dust/dirt out of the bearings. I haven't had a Stihl tip let go on me. Just had a couple that need the tips replaced do to wear on the heel of the tip after many many hours of use.

So, I went back to greasing on the bars that actually have a grease hole. It works for me, so I use it. I do plunge cuts 99% of the time I fell, so I grease them every time I am done cutting with it, so it is ready to go the next time I cut. I do not grease with every tank of fuel. Just more stuff to carry to the woods.

Manual , if I did a lot of plunge cutting or cutting logs that were on snow then I'd grease with a water proof grease . I don't so I only oil the bearings and have only oiled them for 17 years . I have never siezed a sprocket , only bound one up twice .

I'm with you, I don't use grease.
Some guys do and some guys don't.

Note: I need to start using "people" instead of "guys". More woman are popping up around here.

Agreeing with you twice in one day would set a pattern. LOL

I don't anymore either, the rails on my Husky bars are gone long before the sprocket even shows any wear.

The woman thing, yea
but now mine wants to try out a chain saw.
That would mean I would have to stack more often. Grrrrrrrrrr

Woah, I'd say....

I think usage might have a roll in it. For guys that cut less than say 5 cords a year and then the ones that cut 20+ a year.

I used to cut approx 6-8 cord a year and never had a tip problem while greasing, but this year I have cut about 20 cord and lost two tips without greasing.....

Guys that use the saws for less time probably have less chance to sieze a tip, unless they are cutting underwater in deep sand. LOL.

That sucks, mine makes a good stacker and I've tried to get her behind a saw, but she won't. I guess that is a good thing

I dont grease, cut mostly softwood, just occasionally plunge cut and hardly ever lose a tip.
A year ago I got ahold of a couple of Windsor(USA) old stock bars. Was falling hardwood and doing a fair amount of plunge cutting. The tip blew out on the first bar the first day. I replaced the tip (still not greasing) and the bar lasted great. Wish I could find some more.
If I cut hardwood regularly I probably would start greasing but for what I usually do it seems to be a waste of time.
I dont know how it affects the longevity of the tip but at home with an air compressor you can really clean them out. Make it scream and then it freewheels easily. But then it is bone dry on startup for a minute unless you do something to it.

Fs , did you by chance open the tip to see how it actually failed ?

Bearing siezed, no reason to investigate it further....

I don't know about lots of loggers up here don't grease there tips without problems.
It has more to do with tip usage.
You say you plunge cut alot. that increases heat build up and stress on bearings.
I know a guy that pice cuts and is a tip user when delimbing. never uses grease but has divets in his tip. totaly worn out. No bearing failures.
He defeats all practical reason for bearing failures. "Go figure"
the only thing I can figure is he says off the sprocket.

Guys that cut on the landing or are cutting fire wood thats been skidded eat tips up.
I grease if I am going to not use the saw for awhile or if I am cutting in the woods and its raining out. Keeps the tip form rusting when its sitting in the back of my truck.

 

[SRT-Tech]

ok so some of use grease, some dont, great discusion in any case.

but to the guy that said greasing takes too long, i gotta ask: what are you doing wrong that it takes that long?

seriously, it takes MAYBE 1 second per greasehole to inject a fresh squirt of grease.

"oh but i dont wanna carry all that stuff with me its heavy, waaaaa"

well if you cant handle carrying a tiny greasegun that weighs less than an candybar, meybe you should'nt be carrying that saw around eh?

little humor for everyone :hmm3grin2orange: :sword:

Guess that grease gun will fit nice inside your man purse, eh?

point taken...opcorn: opcorn: opcorn:

Never needed to pack one with me... ever. The Stihl bars that I have had on my saws never had a grease hole.

...and I never said greasing a tip takes to long. Just one other thing that I don't have to worry about. Or care about.:censored:
