Hello all, didn't want to 'dig up' and old thread, but since this one is just from a few months ago and pretains to the same 'problems', I thought it was best just to reply here.
I also bought a Husqvarna 450 just a couple months ago, and I to have been having a heap of trouble with it.
I haven't ran more than 5 or 6 tanks of fuel through this saw, its basically brand new. Bought it from a local Husky dealer on a saturday
(they were the only saw dealer open that day...) Found out later, that they ripped me off for about an extra $60
above retail price...
Only reason we purchased a husky, is because we had one before many years ago, and it was a great saw, worked great, lasted a long time, and never required anything more than regular normal maintenance.
Anyway, at first the saw worked ok, but didn't have the power I would expect from a 50cc/3.2hp
Each time I used it, things just got worse.
And No it was not from a dull chain, I sharpen my own chains and keep them sharp.
PLUS I put a brand new Stihl Pro 'Yellow'
(not the 'green' low kick back 'homeowner') Semi-Chisel chain on it.
A few days ago, I was cutting and found that the bar was getting Really Hot, nearly hot enough to burn you if you held your hand on it. It made the oil smoke on the bar. Which I had been watching the oil flow anyway, and had tested often to see if I could get a streak off it. And it kept getting less and less.
Now, it hardly puts out any oil at all. Dumped the Stihl oil out, and replaced it with the 'classic' brand stuff they sold me with the saw, which seems to be thinner. Was able to get a little to sling off the chain, but not near enough.
Note that I also cleaned the bar, oil holes, and oil slot several times during this. Sharpened my chain while I was at it. And then tested it on some firewood rounds about 8-10" in diameter. It was cutting a little better, bar wasn't
AS hot, but the oil flow still just wasn't what it should be. Then on the 5th or 6th cut, the chain locked.
So I put it in the vise, and took the cover off, removed chain. Found that the front nose sprocket had completely seized in the stock husky bar. Couldn't turn the sprocket with anything, it just wouldn't budge no matter what. Agravated, took a propane torch and heated it, burning out what ever debris was in there, and with some effort, finally got it to turn, spun it around several times to clear it, and it turned freely again. Let it cool, re-greased it, tested saw again but still hardly no oil getting to the bar.
And no, i don't expect the bar to last after doing that, don't like the husky bar anyway.Removed bar, and ran saw, oil is just dribbling out the slot.
Sooooo... I'm getting ready to tear into it, and see if I could figure out why its not oiling.
And while I was doing some research, I found this thread. Which has already been helpful.
But I wanted to ask:
Has anyone found 'THE' reason that these husky oilers keep failing?? Or at least what
specific part of the oiler system is failing?
I mean this saw doesn't even have 10 hours of run time on it. And it seems to be the Exact same problem as the OP had. So this isn't just a
'one off' problem, it has to be a design issue of some sort, as it seems this is happening to multiple
Brand New Husky Saws.
I'm also getting ready to order parts, including a new bar.
I was looking at the Oregon 20" Pro-Lite Chainsaw Bar (78 Drive Links) 200SLGK095 from bailieys.
Anyone have any opinions of the Oregon bars? I haven't used them before, but I know I don't care for the husky bars at all...
Also on oregon's website, it shows this bar needs an 8 tooth sprocket, I'm pretty sure the husky 450 comes stock with a 7 tooth. So I may also be upgrading to a rim sprocket while I'm at it.
Any input would be appreciated.~Thanks
